If you’re looking for thicker hair or even regrowth, peppermint oil may be able to take care of that for you. According to a 2014 study published in the Toxicological Research journal, when peppermint oil was applied to mice, it helped with hair regrowth. Of the four studies conducted, the group of mice that were given peppermint oil in jojoba oil (as a necessary carrier oil) ended up with thicker hair, and greater follicle numbers and depth. Granted, humans aren’t mice, but the researchers felt it was enough to conclude the studies were definitely onto something in regard to the positive effect of the essential oil.
“Research is limited, but peppermint oil could help hair growth,” board-certified dermatologist Craig Ziering, D.O., F.A.A.D. told Shape. “Menthol, the main component in peppermint oil, has been shown to increase blood flow to the area where it is applied. Better blood circulation to the skin could encourage more hair to grow in the affected area.” If you feel your hair could use a boost in the follicle area, then give peppermint oil a try.
