Peppermint, onion, green tea and massage

Peppermint oil, onion juice, green tea and scalp massage are not NHS treatments for pattern hair loss. The evidence is small, preclinical, or too uneven for a success rate. They are not a substitute for seeing a GP about sudden or patchy loss, or for minoxidil where pattern loss is the diagnosis.

See a GP if hair loss is sudden, patchy, or comes with illness, a rash, or other symptoms. The NHS asks for that conversation before a private clinic.

These four circulate because they are already in the kitchen. That is a poor proxy for evidence.

How strong is the evidence?

Onion juice, peppermint oil and green tea do not have a regrowth percentage worth quoting. The papers people forward are small, old, or not in humans. The NHS does not list any of them next to minoxidil and finasteride.

Onion juice and essential oils sting and can trigger dermatitis. If you try them, stop when the skin complains. Do not put them on broken skin, and do not use them on a child. Green tea as a drink is an ordinary drink. A concentrated extract is a supplement, with a dose the NHS has not set for hair.

Massage

Rubbing the scalp with your fingertips for a few minutes is cheap and, on healthy skin, low risk. There isn’t a trial that turns a set number of minutes into a hair-growth treatment. Tight, aggressive massage on a sore scalp is the opposite of help. A plastic massager is the same idea with a handle. It is not a light device and not a needle.

Where the evidence is clearer

Rosemary oil has a six-month randomised comparison with minoxidil 2%. Pumpkin seed oil has a placebo trial in men. Those pages quote numbers because the papers have numbers. These four do not have a result of that kind.

If you want a device rather than a kitchen experiment, red light has a larger clinical literature. The trials are on does red light work, and the hats are compared at red light hats.

Common questions

Does onion juice regrow hair?

There isn’t a result strong enough to say it regrows hair. It is not an NHS treatment. It can irritate skin.

Does peppermint oil work?

Laboratory and animal work is not a reason to quote a percentage for people. The NHS does not list peppermint oil for pattern hair loss.

Is scalp massage worth doing?

It can be pleasant and it is low risk if the scalp is intact. It will not stand in for minoxidil or for a GP visit.
