Natural hair loss treatment: what helps

In shortA natural treatment helps when it fixes a cause: iron if you're low, enough protein, less traction on the hair. For pattern hair loss, oils, vitamins and shampoos have little good evidence, and none match minoxidil. Start with a blood test, not a supplement.

Step 1 of 6

Which are you?

Fix what a blood test finds

The HSE lists hair loss as a symptom of iron deficiency anaemia, and thyroid problems thin hair too. Both are found on a routine blood test and both are treatable. Taking iron or vitamin D without a test is guesswork, and too much iron is harmful.

Eat enough

Hair is made of protein and needs a steady supply of energy. Crash diets and fast weight loss, including on weight-loss injections, are a well-known trigger for shedding two or three months later. It usually recovers once your weight and eating settle.

Go easy on the hair itself

  • Loosen tight ponytails, braids and extensions: constant pulling causes traction hair loss at the hairline.
  • Keep heat tools and bleaching to a minimum on fragile hair.
  • Treat dandruff or an itchy scalp. Scratching and inflammation don't help.
  • Don't smoke. Smoking is linked with earlier pattern hair loss.

Oils, vitamins and shampoos

ProductWhat the evidence says
Rosemary oilOne small trial against weak minoxidil. Not enough to rely on.
BiotinHelps only in true biotin deficiency, which is rare. It can also distort some blood tests.
Caffeine shampooNo good trial evidence that it changes pattern hair loss.
Saw palmettoSmall studies, weak effect. Not a substitute for a prescribed medicine.
Scalp massageHarmless and pleasant. Evidence is thin.

Supplements: who needs them

People who are low in something. That means iron if your ferritin is low, vitamin D or B12 if a test shows a shortage, and a balanced diet if you have been eating very little. For everyone else, hair supplements add cost and nothing more. Some contain high doses of biotin, which can throw off thyroid and heart blood tests, so tell your GP if you take one.

When home treatment isn't enough

If the thinning follows a pattern and keeps going for six months, home measures won't stop it. See your GP first if the hair loss is sudden, patchy, coming out in clumps, or your scalp is itchy, sore, scaly or scarred. Those need a diagnosis before any clinic treatment.

Questions people ask

Which vitamin deficiency causes hair loss?

Low iron is the common one, especially in women. Very low vitamin D, B12 or zinc can add to it. A GP blood test tells you.

Can I regrow hair naturally?

If the cause was temporary, such as illness, a baby or weight loss, yes: it usually regrows by itself. Pattern hair loss doesn't.

Does stress cause hair loss?

A major shock or illness can trigger shedding two or three months later. It usually settles within about six months.

Is rosemary oil as good as minoxidil?

No. One small trial compared it with a weak minoxidil solution. That is not enough evidence to rely on.
