How it works
Menthol triggers TRPM8 cold-receptors — the instantly recognisable cool.
Encourages a brief vasodilation response that boosts blood flow to the scalp.
Astringent action helps normalise oil production between washes.
Soothes itch and scalp tension linked to product build-up.
History & heritage
Mentha × piperita is a hybrid mint first classified in England in 1753, but the mint family has been used medicinally in Egypt, Greece and Rome for thousands of years. Its cooling, tingling character comes from menthol, which activates the TRPM8 cold-receptor in the skin. Traditional herbalism prescribed peppermint for headaches, digestion and scalp complaints; modern interest surged when a 2014 study in Toxicological Research showed 3% peppermint oil outperformed both saline and 3% minoxidil for follicle count and dermal thickness in a mouse model — one of the strongest single-oil results ever published.
Traditional uses through history
- 01Ancient Egyptian temple medicine
- 02European folk remedy for headaches and tension
- 03Traditional scalp massage oil for cooling and clarity
- 04Modern aromatherapy for focus and alertness
The 2014 Oh et al. peppermint oil study is the most-cited paper on the ingredient. Menthol's activation of the cold-receptor causes a reflex increase in scalp micro-circulation — the same mechanism that produces its familiar tingle. Peppermint also has documented antimicrobial activity useful for scalps prone to dandruff or biofilm buildup.
How it actually works
Triggers cold-receptor circulation
Menthol activates TRPM8, producing a reflex rush of blood to the scalp that delivers oxygen and nutrients.
Cools and refreshes
The signature tingle isn't just sensory — it signals active scalp engagement.
Reduces microbial load
Documented action against common scalp yeasts and bacteria that can drive flaking and itch.
