Benefits of Peppermint Oil for Hair

    • Can lead to hair growth: Findings published in Toxicological Research say a peppermint oil solution led to more hair growth than minoxidil, a hair-growth product approved by the FDA.1

      Though, there isn't a ton of conclusive research that proves using peppermint oil will definitely cause an increase in growth.

    • Increase hair thickness: "Peppermint essential oil stimulates blood circulation to the skin, which may help with increasing dermal thickness, follicle number, and follicle depth." But Sara Panton, the co-founder of Vitruvi, warns that it's certainly clarifying. In fact, a study in Microvascular Research found a 4% menthol solution "caused blood vessels to widen, which increases blood flow."
      Reduce inflammation: Plus, peppermint has a pleasant cooling sensation when applied topically, and that sensation can help to reduce skin inflammation, Panton adds. "The final benefit is simply that it can help you relax because it is so cooling and calming—which is always a good thing when you're waiting for your hair to grow."
