What the Research Actually Says About Traction Alopecia in South Africa

Most of what gets written about hair loss from tight styling is guesswork dressed up as advice. It does not have to be. Some of the best research in the world on this subject was done here, in Cape Town, on South African hair — and the numbers are worth knowing.

This article summarises published, peer-reviewed findings. Sources are listed at the end so you can read them yourself.

How common is it, really?

A team led by Professor Nonhlanhla Khumalo at the University of Cape Town and Groote Schuur Hospital examined 874 African adults in Cape Town. They found traction alopecia — hair loss caused by sustained pulling — in 22.6% of everyone examined.

• 31.7% of women had it, against 2.2% of men.
• In separate work, 17.1% of schoolgirls aged 6 to 21 already showed signs.
• Central centrifugal cicatricial alopecia affected 6.7% of women over 50.

Close to a third of women. This is not a rare condition affecting other people.

The single biggest risk factor

Here is the finding that should change how you plan a style. In the same Cape Town population, prevalence of traction alopecia rose to 48% — nearly one in two — where extensions had been attached to chemically relaxed hair.

A follow-up study of 574 schoolgirls and 604 women put a number on it. Adding traction to relaxed hair carried an odds ratio of 3.47 compared with natural hair — roughly three and a half times the risk.

Relaxing weakens the fibre. Tension pulls on the follicle. Neither alone is as damaging as the two together, and it is the combination that is routine in salons.

Pain is a warning, not a side effect

The 2008 study reported that only 18.9% of people with traction alopecia had never experienced hairdressing-related symptoms. Put the other way round: more than four in five had felt something — tenderness, stinging, bumps — before the loss appeared.

The authors concluded that avoiding hairdressing-related symptoms, and not applying traction to chemically processed hair, could reduce the risk of developing it. That is about as clear as clinical research gets. If a style hurts, that is information.

Why textured hair breaks more easily

A review in the International Journal of Trichology sets out the structural reasons. Afro-textured hair is elliptical rather than round and twists along its length, so mechanical stress concentrates at the bends. It also has fewer cuticle layers than straight hair, leaving less protective armour.

The same review notes that combing hair that has not been lubricated leads to breakage, and that breakage occurs at the points of highest combing force. This is the case for detangling with product rather than dry-combing, and for working from the ends upward.

What the evidence supports

Protein treatments on relaxed hair

A 2020 study in the International Journal of Cosmetic Science tested hydrolysed keratin peptides on sodium hydroxide-relaxed African hair. Mid-weight peptides penetrated into the cortex and raised break stress by around 18.6%. Premature fibre breakage fell from 15 of 50 untreated fibres to 6 of 50 treated.

Oiling before you wash

The often-cited 2003 study by Rele and Mohile compared mineral, sunflower and coconut oils. Coconut oil was the only one to meaningfully reduce protein loss, cutting it by up to 39% in damaged hair and 17% in undamaged hair as a pre-wash treatment. The authors attributed this to lauric acid’s ability to penetrate the shaft.

Scalp massage — promising, but hold it lightly

A 2016 Japanese study found daily standardised scalp massage increased hair thickness from 0.085 mm to 0.092 mm over 24 weeks. It involved nine men. A larger 2019 survey found 68.9% of 327 respondents reported stabilisation or regrowth, but it was retrospective, self-reported and had no control group — limitations the authors state plainly.

Massage is pleasant, free and unlikely to hurt. It is not proven to regrow hair, and we are not going to tell you it is.

Practical takeaways

• Do not add tension to relaxed hair. If you relax, wear looser styles. If you braid tightly, reconsider relaxing. The combination is the risk.
• Treat pain as a stop signal, not something to endure.
• Detangle lubricated, never dry, from ends to roots.
• Use protein on chemically processed hair — the measured benefit is real.
• Oil before washing rather than only after.
• Act early. Traction alopecia is reversible in its early stages and scarring becomes permanent later.

If you have thinning edges, tenderness that does not settle, or patches that do not recover after resting the hair, see a dermatologist. In South Africa you can ask your GP for a referral. Early traction alopecia responds to treatment; scarred follicles do not come back.

Where our products fit

We make cosmetic products, not medicines, and we are not going to claim otherwise. What the research above supports is a routine built on lubrication before manipulation, protein for chemically processed hair, and gentleness.

That is what Miracle Gro Hair Butter and the Keratin Creamy Hair Mask are built for — available together in the Hair Care Bundle. No product prevents traction alopecia. Only reducing tension does that.
