You noticed it at the temples first. A little more forehead than there used to be, a thinning just above the ear, a hairline that has quietly moved back along the exact line where your hair has been pulled for years. Maybe there are small bumps after a fresh install. Maybe your scalp aches for a day or two afterwards and you have always assumed that was simply what a good, neat style costs.
I want to start with the good news, because there is genuinely some, and it is not something I can say about most of the hair loss I write about on this site.
Traction alopecia is preventable, and in its early phase it is reversible. Not managed. Not slowed. Reversible — if the tension comes off while the follicles are still there. That makes it almost unique in this field, and it is why it is worth understanding properly rather than being warned about vaguely.
Two things I want to establish before I go any further. First, this condition disproportionately affects Black women, and that fact has more to do with the tension that particular styling techniques apply than with the hair itself — a point the dermatological literature has become considerably better at making in the last decade (Haskin & Aguh, 2016). Second, my job here is not to tell you how to wear your hair. Hair carries meaning, professional expectation, cultural identity and a great deal of practical convenience, and a physician who ignores all of that in favour of just wear it loose has given advice that will not be followed and does not deserve to be. What I can usefully offer is the mechanism, the early signs, and the specific modifications that reduce tension without asking you to abandon a style you value.
What Traction Alopecia Actually Is
Traction alopecia is hair loss caused by sustained mechanical tension on the follicle.
The follicle is anchored in the dermis by connective tissue and, at the level of the bulge, by the arrector pili muscle. It tolerates transient force perfectly well — brushing, a ponytail for an evening, wind. What it does not tolerate is prolonged, repetitive traction applied in the same direction for hours at a time, day after day, over months and years.
Under that load, two things happen in sequence. Early on, the tension pulls hairs out and produces a perifollicular inflammatory response — you may see small papules or pustules around the follicles, and the scalp may be tender or itchy. This is the phase in which the follicle is still intact and still capable of recovery.
If the load continues, the inflammation resolves into fibrosis. The follicle and its stem cell reservoir are replaced by scar tissue, the follicular opening closes over, and the skin takes on a smooth, shiny, pore-less appearance. At that point traction alopecia has become a scarring alopecia, and the hair in the affected area will not return (Billero & Miteva, 2018).
The whole clinical task is to act in the first phase.
Where It Shows Up
The distribution of traction alopecia is a map of where tension has been applied, which is what distinguishes it from every other kind of hair loss on this site.
The frontal and temporal margins are by far the most common sites — the hairline above the forehead and the area in front of and above the ears. This is because most styles that pull do so backwards and upwards from the face, and the marginal hairs are the finest and most weakly anchored on the scalp.
Behind the ears and along the nape are the next most common, particularly with styles secured at the back or with headwear that sits and pulls in a fixed line.
Along a fixed part or along the lines of a braided pattern, where the traction follows the exact geometry of the style, sometimes producing linear or geometric areas of loss that mirror the parting pattern.
And crucially: the crown and mid-scalp are usually spared in pure traction alopecia — which is precisely the reverse of pattern hair loss, and one of the most useful distinguishing observations you can make yourself.
The fringe sign
There is one clinical finding worth learning to recognise, because it is both characteristic and easy to see.
In traction alopecia of the marginal hairline, a narrow band of fine, short hairs is frequently retained at the very front margin, with the loss occurring immediately behind it. It looks like a wispy fringe standing in front of a thinner area. This is the fringe sign, described by Samrao and colleagues, and its usefulness is that it helps distinguish traction alopecia from frontal fibrosing alopecia — a scarring condition in which the whole frontal hairline recedes as a band and the marginal hairs are not retained (Samrao et al., 2011).
If you have a wispy retained fringe with thinning behind it, that points toward traction. If your entire hairline has moved backwards as a clean band with no retained fringe, and particularly if your eyebrows have thinned as well, that warrants a dermatology appointment rather than a styling change, because frontal fibrosing alopecia is a different disease that needs medical treatment.
What Causes It — Named Plainly
Any practice that holds hair under tension for extended periods can cause it. The realistic list:
- Tight ponytails, buns and topknots, especially worn daily and in the same position
- Braids and cornrows installed with tension at the root, particularly when small and tightly gripped
- Weaves and sew-ins, where the weight of added hair is borne by the wearer's own braided base
- Bonded and glued extensions and wigs, and clip-in pieces worn in the same place repeatedly
- Locs, particularly as length and weight accumulate, and particularly at the margins
- Tight wig caps and lace fronts, including the tension of the cap itself and the repeated adhesive removal at the hairline
- Chemical relaxing combined with tension, which is a specific and well-described amplifier — a relaxed or chemically processed shaft has reduced tensile strength, and the same styling force does more damage. Khumalo and colleagues found the risk of marginal traction alopecia to be substantially higher where tension was applied to relaxed hair (Khumalo et al., 2008)
- Occupational and religious head coverings worn tightly, pinned in a fixed position, or over hair pulled back beneath them; and helmets, hairnets and surgical caps worn for long shifts
- Nightly tight wrapping or tying, which extends the daily hours under tension considerably
The rule that makes all of this actionable: if it hurts, it is too tight. Pain, a pulling sensation, a headache after installation, tenderness when you move your head, bumps or pustules at the hairline within a day or two — these are not signs that the style is set well. They are the follicle reporting mechanical stress. Discomfort that is described as it means it's neat or it settles in a couple of days is the single most reliable early warning you will get, and it arrives long before the hairline visibly moves.
Early Signs, Before You Can See a Gap
Because reversibility depends entirely on timing, these are worth knowing:
- Pain or tenderness during or after styling — the first and most useful sign
- Small bumps or pustules at the hairline or along parts after installation
- Broken hairs and short spiky regrowth at the margins
- Widened partings within a braided pattern
- A hairline that has become fuzzy and irregular rather than defined
- Increased shedding at removal that is out of proportion to the time the style was in
- And the retained wispy fringe described above
Reducing Tension Without Giving Up Your Style
This is the part I actually want to be useful. The following changes reduce load without requiring anyone to stop wearing braids, locs, wigs or a covering.
Change the position regularly. Tension damage is cumulative in the same place. A ponytail worn at the same height every day for years concentrates the load on the same follicles. Moving the position — higher, lower, off-centre, and rotating the parting — distributes it. Rotating parting lines between installs matters more than most people expect.
Ask for larger sections and looser roots. Smaller braids and tighter roots mean more tension per follicle. A larger section size and a deliberately looser first centimetre at the root reduces the load substantially while looking essentially the same. Stylists will do this if you ask, and it is a reasonable thing to ask for.
Take the style out sooner. Long wear increases total tension-hours, and regrowth increases the leverage on the follicle as the base of the braid rotates. Six to eight weeks is a commonly given ceiling, and shorter is better for the margins.
Give the scalp genuine breaks between protective styles. A week or two of low-tension wear between installs is not wasted time. It is the interval in which perifollicular inflammation settles.
Reduce the weight. With weaves, extensions and locs, weight is force. Lighter added hair, fewer pieces, and shorter lengths all reduce the load on the anchoring follicles — and locs in particular benefit from attention to weight at the margins as length accumulates.
Protect the hairline specifically. The marginal hairs are the finest and most vulnerable on your head, and they are the ones most often recruited into a sleek edge. Leaving the very front out of tension-bearing sections, avoiding repeated adhesive at the same line, and being cautious with edge-laying that involves pulling all matter disproportionately.
Separate chemical processing from tension in time. If hair is relaxed or coloured, giving it recovery time before a tension-bearing style — and avoiding both on the same day — reduces the compounding effect that the literature describes.
Loosen the night. Satin or silk on the pillow reduces friction; a loose bonnet or a loose scarf achieves the same protection as a tight one without adding hours of tension.
Check the covering, not the wearer. For religious, cultural or occupational head coverings, the tension usually comes from how the hair is secured beneath the covering rather than from the covering itself. Varying the position of pins and ties, avoiding a tightly pulled base underneath, and using softer fabric ties are modifications entirely compatible with wearing what you wear.
When to See a Dermatologist
Please make an appointment if:
- There is a smooth, shiny area where you cannot see the pore openings — this suggests fibrosis, and while it means that area will not recover, treatment can protect the margin around it
- There is persistent pain, redness, pustules or scaling
- The entire hairline has receded as a clean band with no retained fringe, especially with eyebrow loss — this raises frontal fibrosing alopecia
- The loss is not in a tension distribution — if the crown is thinning while the margins are fine, something else is happening, likely pattern loss
- Nothing has improved three to six months after the tension came off
A dermatologist will examine the scalp with dermoscopy, which shows whether follicular openings are preserved (Miteva & Tosti, 2012), and may recommend a biopsy where scarring is suspected. Early traction alopecia is treated medically as an inflammatory condition, and there is genuine evidence for intervention in the reversible phase — which is another reason not to wait and watch.
The Bottom Line
Traction alopecia is caused by sustained mechanical tension, appears at the frontal and temporal margins rather than the crown, is often preceded by pain, bumps and broken hairs, and frequently leaves a retained wispy fringe at the very front. In its early phase the follicles are intact and the loss is reversible. If tension continues, the follicles are replaced by scar and the loss becomes permanent.
You do not have to abandon protective styling to prevent it. Larger sections, looser roots, rotated positions and parting lines, shorter wear, real breaks between installs, less weight, and specific protection of the hairline all reduce load meaningfully.
And the rule that carries all of it: if it hurts, it is too tight. Pain is not the price of a neat style. It is early information, arriving while there is still something to do about it.
Dr. Susan Lin's Clinical Perspective
"This is the only common hair loss I can honestly describe as preventable, which is why I would rather be practical about it than moralistic. Nobody needs a physician telling them what their hair should mean or how they should wear it — that advice gets ignored, and deservedly. What people do need is the mechanism and the timeline: tension causes perifollicular inflammation, sustained tension converts that inflammation into fibrosis, and fibrosis is the end of the follicle. Everything useful sits in the interval between those two states. So I ask about pain rather than about style, because pain is the earliest reportable signal and it arrives while the follicles are still recoverable. And I ask about the hairline specifically, because the marginal hairs are the finest on the scalp and they are the ones we most often ask to do the hardest work."

Mechanism Spotlight: From Tension to Fibrosis — Where the Reversible Window Closes
Traction alopecia is a two-stage disease, and the boundary between the stages is the whole clinical story.
Stage one is mechanical and inflammatory. Sustained traction transmitted along the hair shaft acts on the follicle's anchoring structures. Hairs are extracted prematurely from anagen, and the surrounding tissue mounts a perifollicular inflammatory response — histologically an infiltrate around the upper follicle, clinically the tenderness, erythema and follicular papules that people describe after a tight installation. At this stage the follicular unit is preserved. The bulge, which houses the stem cell population from which the entire lower follicle is rebuilt each cycle, is intact. Remove the load and the follicle re-enters its normal cycle; regrowth over subsequent months is the expected outcome.
Stage two is fibrotic. Where traction is maintained, the chronic inflammatory response gives way to deposition of fibrous tissue in place of the follicular unit. Histopathological series of traction alopecia describe a progression from preserved follicular architecture with increased telogen and vellus hairs in early disease, to loss of terminal follicles with fibrous tracts and retained sebaceous glands, and finally to frank scarring in late disease (Billero & Miteva, 2018). Once the bulge stem cell reservoir is destroyed and replaced by scar, there is no template from which the follicle can regenerate. The follicular opening closes, and the surface becomes smooth and shiny — the same clinical appearance that defines the primary cicatricial alopecias.
Two practical consequences follow directly. First, the useful interventions all belong to stage one, which is why the presence of pain, bumps or broken hairs matters more than the presence of a visible gap: the symptoms precede the gap by a long way. Second, relaxed or chemically processed hair shifts the threshold, because a shaft with reduced tensile strength transmits and concentrates styling force differently — which is consistent with epidemiological work finding markedly higher rates of marginal traction alopecia where tension is applied to chemically relaxed hair (Khumalo et al., 2008).

MD HAIR Product Recommendation
MD® Scalp Essential — /products/scalp-essential
Let me be clear about the order of operations, because it would be dishonest to imply otherwise: the intervention that treats traction alopecia is removing the tension. No topical substitutes for that, mine included, and a product applied under a style that is still pulling is treating a symptom while the cause continues.
Where MD® Scalp Essential earns its place is the recovery phase — the months after the load comes off, when the perifollicular environment at the margins is settling and the follicles are re-entering their cycle. It is a lightweight, non-occlusive leave-on formulated to support a comfortable, balanced scalp environment, which is exactly what a hairline that has been under mechanical stress needs, and its texture is deliberately light enough not to add weight or residue at the margins. It goes on scalp rather than on hair. It is drug-free and hormone-free, so it does not interfere with anything a dermatologist has prescribed — though as with anything applied to skin under active medical treatment, clear it with them first, and do not apply it to broken skin, open pustules or acutely inflamed areas. Physician-formulated by Dr. Susan F. Lin, M.D. under the MD® mark (U.S. Reg. No. 4,471,494), manufactured in FDA-registered, GMP-compliant facilities in the USA. A cosmetic product, not intended to diagnose, treat, cure, or prevent any disease — and specifically, it does not treat scarring alopecia, which requires a dermatologist.
Alongside it: MD Nutri Hair™ — /products/nutri-hair-supplement
Because the reversible phase of traction alopecia is fundamentally an inflammatory one, I pair the topical with an internal input rather than asking you to choose. The best-evidenced thing I can tell you about MD Nutri Hair™ concerns inflammation: its lilac component is standardized for verbascoside, a plant phenol which in controlled laboratory studies on human dermal papilla cells reduced the release of pro-inflammatory signals including IL-1α, IL-6, IL-1β and TNF-α, induced cell proliferation, and prevented testosterone-induced cell death. Those are cell studies in a dish, not human trials; the authors state that clinical study is still needed, and the verbascoside studied came from Acanthus rather than lilac — the same molecule from a different botanical source, and not a study of our own material (Wisuitiprot et al., 2022). The capsule is a once-daily 300 mg proprietary blend with vitamin B3 as niacinamide, vitamin E as alpha tocopheryl acetate, and D-biotin at 0.05 mg — a sensible cofactor dose rather than a lab-distorting megadose — plus flaxseed powder, lignan powder and lilac. In the MD Nutri Hair™ 30-day in-office consumer use study (30 subjects, self-reported), 95% saw improved hair appearance, 90% reported better manageability, and 75% reported increased fullness. Individual results vary. As a dietary supplement it is not intended to diagnose, treat, cure, or prevent any disease, and it is not FDA approved — no dietary supplement is. Label warning: keep out of the reach of children. Do not take if you are pregnant or breast feeding. For adults only; one capsule daily.
A note on the assessment window: ninety days is the minimum honest period in which to judge anything here, and for traction recovery specifically, allow three to six months after the tension comes off before drawing conclusions. Photograph the hairline monthly under the same light.
A note on authenticity: genuine MD HAIR™ and MD Nutri Hair™ products are sold only through mdhair.com, md-factor.com, and the official La Cañada Ventures, Inc. stores on Amazon and Walmart. We cannot verify the storage, handling, labelling or lot integrity of units bought anywhere else.
