Peppermint essential oil

Peppermint essential oil is used to soothe inflammation, irritation and itchiness on skin and scalp. It promotes wound-healing, and it is also touted as a natural remedy for soothing bug bites, and providing relief in pruritus, a common skin infection which leads to rashes, hives and itchiness.

Menthol, the main component in peppermint oil (and what causes its cooling sensation) has been shown to increase blood flow to the scalp. This positively impacts blood vessels, stimulating regrowth and follicle depth, for thicker, stronger hair strands.
