LimitedThe famous result is a mouse study. The tingle you feel is a cold-receptor trick, not proof of circulation change in humans.

The study usually cited treated mice with 3% peppermint oil, which grew thicker hair than minoxidil controls. There is no human trial in Evi's research file. The cooling tingle comes from menthol activating cold receptors — a sensation, not evidence of changed circulation in people.
Verdict: unproven in humans. If a peppermint product appeals, buy it for the feel — and read our rosemary piece for the ingredient with a human trial behind it.
