Peppermint Essential Oil
A cooling, tingling essential oil that stimulates scalp circulation and freshens breath, beard, and body.
Peppermint essential oil (Mentha piperita) is 40–50% menthol — the compound responsible for the cooling sensation and the mild vasodilation that boosts scalp and follicle circulation. In shampoo, beard wash, and body wash, peppermint delivers a signature clean-tingle finish and modest hair growth support.
