Hair loss myths, checked against the evidence

Everyone seems to have an opinion about hair loss. Some advice is harmless, some is costly, and some delays effective treatment. Here are ten myths we hear often in Malaysia, and what the evidence says instead.

Myth 1: Losing any hair every day is a bad sign

It is normal to shed some hair every day. The American Academy of Dermatology says shedding between 50 and 100 hairs a day is normal ¹. You will notice more on wash days or after brushing. Worry when shedding is clearly more than usual for you, comes out in clumps, or leaves visible thinning.

Myth 2: Baldness only comes from your mother's side

Pattern hair loss is influenced by several genes inherited from both parents, not just your mother's family ^{2 3}. Looking at your maternal grandfather alone does not predict your future.

Myth 3: Only men lose hair

Women also experience pattern hair loss, usually as widening of the parting and thinning on top rather than a receding hairline ^{4 5}. Women can also have shedding after childbirth, illness or iron deficiency. See iron deficiency and hair loss.

Myth 4: Washing your hair often makes it fall out

Hairs that come out during washing were already loose and due to shed. Washing simply releases them. Avoiding washing does not save hair, and a build-up of oil and flakes can make the scalp uncomfortable. Wash as often as suits your scalp and hair type ⁶.

Myth 5: Wearing caps or helmets causes baldness

There is no good evidence that normal cap or helmet use causes pattern hair loss. Very tight headgear worn for long hours can contribute to traction on the hair in some situations, but ordinary use is not a cause of balding. See helmets, caps and hair loss.

Myth 6: Shaving makes hair grow back thicker

Shaving cuts hair at the surface. It does not change the follicle, the number of hairs, or how thick each hair grows. Stubble feels coarse because it has a blunt tip. See does shaving make hair thicker?.

Myth 7: Hair loss treatments do not work at all

Some products do not work, but well-studied treatments do help many people. Minoxidil and, for suitable men after medical advice, finasteride have good evidence for slowing pattern hair loss and improving hair in many users ^{5 7 8}. Results vary, and they take months to show. See minoxidil in Malaysia.

Myth 8: If you stop treatment, you will lose more hair than before

When people stop minoxidil or finasteride, the hair maintained by the treatment is gradually lost over the following months, returning toward where it would have been without treatment ^{7 8}. Treatment does not make the underlying condition worse; it simply stops working when it is stopped.

Myth 9: Natural oils and home remedies are always safe

Natural does not always mean safe. Some herbal products sold for hair, such as he shou wu, have been linked with liver injury ⁹, and some oils and remedies can irritate the scalp. Evidence for most home remedies is limited ¹⁰. See is he shou wu safe?.

Myth 10: Creatine and gym workouts cause baldness

A small 2009 study raised concerns about creatine and DHT, but it did not measure hair. A 2025 randomised trial found no difference in DHT or hair measures over 12 weeks ¹¹. Exercise itself is good for health. See creatine and hair loss.

Where myths come from

Myths often start with a real observation that gets misinterpreted. For example, hair loss often begins in the same years people start gym training or wearing helmets daily, so one is blamed for the other. Online forums can repeat these stories quickly. See forum advice on hair loss.

How to check a claim

• Ask where the information comes from: a health body, a published study, or a personal story?
• Be cautious of products claiming dramatic, fast or certain results
• Talk to a doctor or pharmacist before spending money

The bottom line

Many hair loss beliefs are not supported by evidence. Shedding some hair is normal, genes come from both parents, women lose hair too, and proven treatments do help many people. When in doubt, check the source and get a proper assessment.
