Home remedies for growing edges back: what actually works
Last updated 2026-07-09
TL;DR
A few home remedies have real evidence for thinning edges: rosemary oil matched minoxidil 2% in a 2015 trial, scalp massage thickened strands in a 2016 study, and correcting low iron or vitamin D reduces shedding. None work overnight. None reverse scarring. The first step that matters most is removing whatever pulls on your hairline.
Why are your edges thinning in the first place?
Before any remedy matters, you need to know what you are dealing with. The two most common causes of thinning edges in Black women and women with textured hair are traction alopecia and telogen effluvium, and they respond differently to home treatment.
Traction alopecia is hair loss caused by repeated mechanical tension on the follicle, from braids, weaves, ponytails, buns, or tight headbands worn consistently over time. The American Academy of Dermatology notes that traction alopecia is one of the most preventable forms of hair loss, and that catching it early, before follicle scarring sets in, gives the best chance of regrowth [1]. If your edges look thin but the skin at your hairline still looks normal (no shine, no absence of follicle openings), you are likely still in the reversible stage.
Telogen effluvium is a temporary shed triggered by stress, illness, hormonal shifts, or nutritional deficiency. New mothers often deal with this around three to four months postpartum, and it usually resolves on its own within six to twelve months. If you have recently been through something physically or emotionally intense, that timeline matters for setting expectations. See our guide on postpartum hair loss if that context fits.
A third possibility, less common but worth ruling out, is alopecia areata, an autoimmune condition where the immune system attacks follicles. Home remedies do not touch autoimmune activity. If you see smooth, coin-shaped patches or complete absence of hair with no obvious traction history, see a board-certified dermatologist before spending money on oils.
For most readers here, the cause is traction, chronic product buildup stressing the follicle, or some mix of tension and a nutritional gap. That is where home remedies have real, documented room to help.
Which home remedies actually have evidence behind them?
Let me be honest with you upfront: the research on natural hair growth remedies is thin. Most studies are small, run on people without textured hair, and never look at the hairline specifically. A few remedies still have enough behind them that recommending them is reasonable rather than hopeful.
Rosemary oil is the most studied natural option. A 2015 randomized controlled trial in SKINmed Journal compared rosemary oil to minoxidil 2% over six months in men with androgenetic alopecia [2]. Both groups had similar hair count increases at six months, and the rosemary group reported less scalp itching. The mechanism is thought to involve improved circulation and inhibition of DHT (dihydrotestosterone) at the follicle. The study used Rosmarinus officinalis leaf extract diluted in a carrier oil, applied twice daily. This does not prove rosemary oil grows edges back after traction, but it is the closest rigorous comparison we have. Our deeper explainer on rosemary oil for hair growth covers dilution ratios and how to make your own.
Scalp massage has a small but genuinely interesting study behind it. A 2016 Japanese study in ePlasty found that standardized scalp massage (four minutes daily for 24 weeks) increased hair thickness in nine healthy male participants [3]. The proposed mechanism is mechanical stretching of dermal papilla cells. Four minutes a day costs nothing and asks almost nothing of you. At the hairline, use the pads of your fingers in small circular motions. No fingernails.
Castor oil is everywhere in the natural hair community. Honest answer: no peer-reviewed clinical trial confirms it grows hair. What it does have is ricinoleic acid, which some lab research suggests carries anti-inflammatory properties at the follicle level [4]. It also acts as a humectant and can cut breakage at the fragile hairline. Use it as a protective sealant, not a miracle cure.
Peppermint oil showed meaningful follicle stimulation in a 2014 animal study, outperforming minoxidil 3% on some growth markers, but animal data does not translate directly to human results [5]. Diluted in a carrier at 3%, it is low-risk to try, and it is cheap.
Onion juice has a small 2002 study showing regrowth benefit in alopecia areata patients, but only 23 participants and nothing on traction-related loss [6]. The smell is genuinely hard to manage. I would put this low on the priority list unless you are very motivated.
Nutrition matters too. Iron deficiency is strongly linked to hair shedding. A review in the Journal of the American Academy of Dermatology found that serum ferritin below 30 ng/mL correlates with increased hair shedding in women [7]. If you have not had bloodwork recently, getting iron and vitamin D checked is a smarter first move than buying any topical remedy.
How do you use rosemary oil for edge regrowth at home?
Rosemary essential oil is potent and should never go on skin undiluted. The standard safe dilution for scalp use is 2 to 3%, which means roughly 12 to 18 drops of rosemary essential oil per ounce (30 mL) of carrier oil [2].
Good carrier oil choices for the hairline are jojoba (closely mimics sebum, light enough not to clog), sweet almond (lightweight, absorbs well), or coconut oil if your skin tolerates it without breakouts. Castor oil can be a carrier too, but it is thick, so blending it with a lighter oil at a 1:3 ratio works better at the hairline.
Here is a routine that makes sense. Apply every other night to the hairline only, not the whole scalp, which invites over-oiliness and buildup right at the edge. Use a clean cotton swab or your fingertip to press the oil directly into the hairline, then follow with two minutes of circular massage. Wipe any excess off your forehead so it does not migrate into your pores overnight.
Give it at least 90 days of consistent use before judging. Hair growth cycles run roughly 90 days for early anagen (growth phase) to become visible [8]. Quit at 30 days because nothing has shown up yet, and you gave up before the mechanism had time to work.
You can also make your own rosemary-infused oil using dried rosemary herb and a carrier oil. See the step-by-step guide on how to make rosemary oil for hair for the cold and warm infusion methods.
| Rosemary oil (2-3%, every other night) | 6 |
| Scalp massage (4 min daily) | 6 |
| Tension removal alone | 9 |
| Nutritional correction (iron/vitamin D) | 6 |
| Castor oil (sealant use) | 0 |

What does scalp massage actually do for the hairline?
Scalp massage thickens individual strands over time, which reads as a fuller hairline. The 2016 ePlasty study is the best data we have, and it found increased hair shaft thickness after 24 weeks of four-minutes-daily standardized massage [3]. Thickness is not the same as density, but thicker strands look fuller, and the mechanical stimulation is believed to affect dermal papilla cells in the follicle.
For the hairline, technique matters more than force. Press the pads of three or four fingers against the very edge of the hairline and move in small, slow circles. The goal is to shift the scalp skin itself slightly, not rub the surface. Work across the entire hairline, baby hair area and all, spending about 30 seconds per section. Two minutes per session, twice a day, is enough.
If you use a massage tool like a scalp brush, make sure the bristles are soft and wide-spaced. Stiff, narrow bristles on thin, fragile hairline skin cause more trauma than benefit. Manual finger massage is safer at the edges.
One thing scalp massage clearly helps with: product buildup. Edge-care products, gels, and edge control products sit heavily on the hairline and can block follicle openings over time. Gentle massage while shampooing lifts that buildup and keeps follicle mouths clear.
Are there foods or supplements that support edge regrowth?
Yes, and this gets far less attention than topicals deserve to lose to it. Fixing an iron or vitamin D gap does more for deficiency-related shedding than any oil.
Iron is the biggest nutritional factor in hair shedding for women. The Journal of the American Academy of Dermatology review mentioned above found serum ferritin under 30 ng/mL associated with increased shedding [7]. A complete blood count and ferritin panel from your doctor is worth the copay if your edges have been thinning with no obvious traction history. Iron-rich foods include lentils, fortified cereals, spinach (paired with vitamin C for absorption), and red meat.
Biotin gets a lot of marketing attention. The National Institutes of Health Office of Dietary Supplements notes that biotin deficiency is rare in the United States, and there is no strong evidence that biotin supplements benefit people with no deficiency [9]. Eat a varied diet and you are almost certainly not biotin-deficient. Biotin is water-soluble and generally safe at over-the-counter doses (2,500 to 5,000 mcg), so trying it does no real harm. Just keep your expectations low.
Vitamin D deficiency has been linked to non-scarring alopecia in several studies. A 2019 review in the International Journal of Molecular Sciences found an association between low vitamin D levels and alopecia areata, telogen effluvium, and female pattern hair loss [10]. The NIH defines deficiency as serum 25(OH)D below 20 ng/mL [9]. Fatty fish, egg yolks, and fortified dairy raise levels through food; a D3 supplement (1,000 to 2,000 IU daily) is generally considered safe for most adults without conditions affecting calcium metabolism.
Protein is the building block of hair, the keratin structure itself. Under-eat protein (below 0.8 grams per kilogram of body weight per day, the RDA according to the NIH) [9], and no topical remedy compensates. Hair follicles are among the first tissues to lose resources when your body is protein-restricted.
What home remedies should you skip or approach with caution?
Not everything popular in the community is safe or effective. A few categories deserve honest skepticism.
Raw garlic applied directly to the scalp can cause chemical burns and contact dermatitis. People advocate for it based on garlic's antimicrobial properties, but the risk of irritation at the already-thin hairline skin is real. Want the proposed sulfur-compound benefits? Eat garlic. Lower risk, same compounds.
Excessive heat on the hairline, even during deep conditioning, adds trauma to an already stressed area. Hooded dryers and steam caps are fine on lower settings, but direct heat from a flat iron or curling wand near thinning edges speeds up the damage cycle.
Over-oiling is a real problem that rarely gets mentioned. Applying heavy oils like castor oil or Jamaican black castor oil every single day to the hairline can lead to follicular occlusion, where oil, dead skin cells, and product residue block the follicle opening. Every other day maximum, and always follow with a clarifying wash at least once weekly.
Growth-stimulating products with unverified ingredient lists deserve scrutiny. The FDA does not regulate hair growth claims the way it regulates drug claims, so a product can say "promotes growth" without proving it. Read the ingredient list. If the first several ingredients are water, glycerin, and fragrance with a splash of a featured oil far down the list, the active concentration is likely too low to matter.
Petroleum jelly and heavy petrolatum-based products do not grow edges. They coat and protect, which helps shield fragile baby hairs from friction, but they stimulate nothing at the follicle level.
How long does it take to grow edges back with home remedies?
You want a straight answer, not an optimistic hedge, so here it is: months, not weeks, and only if the follicles are still alive.
Human hair grows about half an inch per month on average, though some sources cite a range of 0.35 to 0.45 inches per month [8]. The growth cycle has three phases: anagen (active growth, 2 to 7 years for scalp hair), catagen (transition, about 2 weeks), and telogen (resting and shedding, about 3 months). Follicles gone dormant from traction or stress need to re-enter anagen before any growth shows.
Here is a realistic timeline for non-scarring traction alopecia with consistent home remedy use.
| Timeframe | What to expect |
|---|---|
| Weeks 1 to 4 | No visible growth; this is normal. Focus on killing tension and applying treatments consistently. |
| Months 2 to 3 | Possibly fine "baby hairs" beginning at the hairline. Some people see nothing yet at this stage. |
| Months 4 to 6 | Short new growth (roughly 0.5 to 1 inch if follicles have re-entered anagen). Texture may differ from your mature hair. |
| Months 9 to 12 | Meaningful visible regrowth if the cause was removed and follicles were not scarred. |
| Beyond 12 months | Continued gradual filling in; full density may take 2 to 3 years in moderate cases. |
Scarred follicles, the result of long-term severe traction alopecia, will not respond to home remedies. Under a dermatoscope, scarred follicles show fibrosis where the opening used to be. No oil penetrates that. A board-certified dermatologist can assess it.
Patience is the hard part. Most people who abandon home remedies do so around the 6-week mark, before any biologically meaningful growth window has even closed.
What else do you need to stop doing while using home remedies?
Home remedies work alongside behavior change, not instead of it. Apply rosemary oil every night but still sleep in a tight bun or slick your edges down with strong-hold gel under a tight headband every morning, and the daily tension will swamp whatever benefit the oil provides.
Style rotation is the single most useful change you can make. No hairstyle should pull on the same area for more than two to three weeks at a time. The AAD recommends that people avoid wearing braids, weaves, or extensions for long stretches without breaks [1]. A good rule of thumb: if taking a style out leaves a red mark at the hairline, or the style feels tight the moment it goes in, it is too tight.
Sleep protection matters more than people think. Cotton pillowcases drag on the hairline all night. A satin or silk pillowcase, or a satin-lined bonnet, cuts that friction sharply. Not glamorous advice. Among the cheapest and most consistent things you can do for your edges every single night.
Product buildup at the hairline is a follicle-level stressor most people underestimate. Edge control products, gels, and sprays that never fully wash out form a layer that traps dead skin and hampers follicle function. A sulfate-free clarifying wash at the hairline once a week, even if you protective-style the rest of your hair, keeps the follicle environment cleaner.
For detailed guidance on styles that minimize hairline tension, our guide on protective hairstyles covers installation tension, duration limits, and takedown practices that reduce damage.
Can you use multiple home remedies together, and is that better?
Combining approaches can make sense, but stacking products without a system usually leads to over-manipulation and buildup, both of which hurt more than help. Fewer products used consistently beat more products used randomly.
A practical, low-complexity routine that combines the best-evidenced remedies looks like this.
Night routine, every other night: Cleanse the hairline with a gentle sulfate-free shampoo if there is buildup. Pat dry. Apply 3 to 4 drops of your rosemary-and-carrier-oil blend directly to the hairline. Massage for two minutes with finger pads. Done.
Morning routine: Do not layer more oil on top of last night's application unless you have washed. Apply only what you need for styling, and choose products without petroleum, sulfates, or alcohol in the first five ingredients.
Weekly: One scalp-focused wash day with a clarifying rinse, followed by a light protein treatment if your hair is breaking. Check your style and confirm no single area of the hairline is under repeated tension.
Nutrition runs parallel to all of this. Consistent protein, iron-rich foods, and vitamin D (from food or a supplement if you have a confirmed deficiency) are the internal support structure.
If you want a formula that combines several of these actives without DIY blending, Edge Naturale's collection of natural hair growth products includes options with rosemary, peppermint, and castor oil at pre-tested concentrations. Worth a look if the mixing feels like a barrier to consistency.
Pick a two-step routine and do it every other night for 90 days before judging results.
When should you stop using home remedies and see a dermatologist?
Home remedies suit early-stage, non-scarring hairline thinning where the cause (tension, nutrition, stress) is clear and removable. Some situations need professional eyes instead.
See a dermatologist if your hairline has been thinning for more than a year with no regrowth despite removing traction; the skin at your hairline looks shiny, smooth, or lacks visible follicle openings; you have lost eyebrows or eyelashes alongside scalp hair; the thinning is spreading beyond the hairline into the crown or sides; or you see coin-shaped bald patches anywhere on the scalp.
A dermatologist can perform a dermatoscopy (a non-invasive magnified view of the scalp) and sometimes a scalp biopsy to determine whether follicles are still present and viable [1]. This matters because the plan for reversible traction alopecia is completely different from the plan for scarring alopecias like central centrifugal cicatricial alopecia (CCCA), which is far more common in Black women than previously recognized and needs prescription anti-inflammatory treatment, not oils.
NIH's National Institute of Arthritis and Musculoskeletal and Skin Diseases posts publicly available information on alopecia types and treatments on its website [11]. The AAD also runs a physician-finder tool if you need a referral to a board-certified dermatologist with hair-loss experience.

What does the full evidence picture say about natural hair growth remedies?
Pulling it together honestly: the evidence ranges from "one decent RCT" (rosemary oil) to "plausible but unproven" (castor oil) to "promising in animals, unclear in humans" (peppermint oil). None of these have large, multi-site, randomized controlled trials proving they regrow hairline edges specifically in women with textured hair. That gap in the literature is real, and pretending otherwise would not help you.
Here is what we can say with reasonable confidence.
1. Rosemary oil at 3% in a carrier, applied consistently, is as well-evidenced as any over-the-counter option for hair growth and costs very little. 2. Scalp massage adds a low-risk, zero-cost complement with at least one study showing a thickening effect. 3. Correcting nutrition (iron, vitamin D, protein) is the most evidence-backed internal move for deficiency-related shedding. 4. Removing the cause of traction is not optional. It is the foundation every topical remedy sits on.
Nobody has good data on which combination works best for hairline regrowth specifically. The closest related research covers androgenetic alopecia or alopecia areata, and both differ from traction alopecia in cause and follicle biology. For a broader look at evidence-backed options beyond essential oils, see our article on essential oils for natural hair growth.
Edge Naturale's formulations are built around these same actives. If you want a pre-formulated option with clear ingredient concentrations, their collection is worth a look at the end of your research.
Home remedies for growing edges back are legitimate tools for non-scarring, early-stage hairline thinning. They do not replace a professional diagnosis, and they do nothing without removing the root cause. Set a 90-day timeline, pick the two or three approaches with the best evidence, and be consistent.
Frequently asked questions
Can thinning edges grow back completely with home remedies?
It depends on whether your follicles are still viable. If the thinning is recent and the hairline skin still shows follicle openings (not smooth or shiny), home remedies plus removing tension have a real chance of meaningful regrowth. Scarred follicles from long-term traction will not respond to any topical. A dermatologist can tell you which situation you are in.
How often should I apply rosemary oil to my edges?
Every other night is the sweet spot. Daily heavy oil can cause buildup at the follicle opening. Apply a 2 to 3% dilution (12 to 18 drops per ounce of carrier oil) to the hairline, massage for two minutes, and leave overnight. On off-nights, let the scalp breathe. Give it at least 90 days of consistent use before evaluating results.
Is Jamaican black castor oil actually better than regular castor oil for edges?
No clinical trial compares the two. Jamaican black castor oil is made from roasted castor beans and has a higher pH and ash content. Some practitioners prefer it; others see no difference. Both contain ricinoleic acid, the active component. Regular cold-pressed castor oil is less expensive and better studied in lab settings. Either works as a sealant and protective coating at the hairline.
What is the fastest way to regrow edges at home?
There is no shortcut that actually works. The fastest realistic approach: remove all tension from the hairline immediately, start rosemary oil every other night, add two minutes of scalp massage daily, correct any nutritional deficiencies (get bloodwork for iron and vitamin D), and protect your hairline at night with satin. Do all of these consistently for 90 days. That beats doing one thing sporadically.
Does hair loss from braids grow back?
Yes, in most cases, if caught before scarring occurs. Traction alopecia from braids is one of the most common and most reversible forms of hair loss when the tension is removed early. The American Academy of Dermatology notes it is preventable and, in early stages, reversible. The longer the tension was applied and the more severe the loss, the longer regrowth takes and the less complete it may be.
Can onion juice help grow edges back?
One small 2002 study of 23 alopecia areata patients found topical onion juice outperformed tap water for regrowth in that specific condition. There is no study on traction alopecia or hairline edges specifically. The sulfur compounds in onion may support keratin production. It is low-risk to try if you can tolerate the smell, but the evidence is thin and it ranks below rosemary oil and scalp massage for effort-to-evidence ratio.
How do I know if my edges will grow back or if the damage is permanent?
Look at the skin at your hairline. If you can see small follicle openings and the skin texture is normal, your follicles are likely still active. If the skin looks shiny, smooth, and flat with no visible pores where hair used to be, scarring may have occurred. A dermatologist with a dermatoscope can confirm this definitively. Persistent thinning after six to twelve months of removed tension warrants a professional evaluation.
Does biotin help grow edges back?
Only if you are biotin-deficient, which is rare in people eating a varied diet. The NIH Office of Dietary Supplements states there is no strong evidence that biotin supplements benefit people without a deficiency. Taking it is not harmful (it is water-soluble), but it is unlikely to produce dramatic results. Addressing iron and vitamin D levels is a more evidence-backed nutritional priority for hair shedding.
Can I still wear my hair in braids or ponytails while trying to regrow my edges?
Yes, but with limits. Keep styles loose at the hairline specifically, rotate which areas bear tension, and do not wear any one style for more than two to three weeks without a break. The AAD recommends avoiding extended wear of tight styles without breaks. If an installation causes pain or you see tenting of the scalp skin, ask your stylist to redo it looser. A tight style will undo every remedy you apply overnight.
What should I put on my edges at night to help them grow?
A light application of rosemary oil diluted in jojoba or sweet almond oil (2 to 3% concentration) applied every other night is the most evidence-supported option. Follow with two minutes of gentle circular massage. Cover with a satin bonnet or sleep on a satin pillowcase to reduce friction. Avoid heavy petrolatum or thick pomades nightly; they occlude the follicle with buildup over time.
How do I grow edges back after traction alopecia?
First, remove all tension from the hairline. Then apply a 2 to 3% rosemary oil blend every other night with scalp massage. Check for nutritional deficiencies (iron and vitamin D especially). Protect your hairline nightly with satin. Give it a minimum of 90 to 180 days. If there is no response after six months, see a dermatologist to assess whether scarring has occurred. Our full guide on traction alopecia covers the staging in detail.
Are there any home remedies that are dangerous to use on edges?
Yes. Raw garlic directly on skin can cause chemical burns and contact dermatitis, especially on the thin hairline skin. Undiluted essential oils cause irritation and sensitization. Petroleum-based products used daily can cause follicular occlusion over time. Frequent heat near the hairline worsens traction damage. Any remedy that causes redness, peeling, or increased shedding in the first two weeks should be stopped immediately.
Does hair type or texture affect how well home remedies work on edges?
Curl pattern itself does not change how follicles respond to topical actives. But tightly coiled hair (Type 4) has a curved follicle that makes it more prone to breakage from tension and manipulation, so the behavior-change part (removing tight styles) matters even more. Coily hair also tends to be drier at the hairline, so sealant oils like castor oil serve an important protective role alongside any growth-stimulating ingredient.
