Studies have shown that peppermint oil possesses properties that can promote hair growth and prevent hair loss. Applying peppermint oil to your scalp helps to stimulate blood circulation, which, in turn, nourishes your hair follicles and encourages healthy hair growth. The menthol in peppermint oil has a cooling effect on the scalp, which not only refreshes but also invigorates the hair follicles, fostering an ideal environment for growth.
