Hair consists of a protein called keratin, which is produced in hair follicles in the outer layer of the skin. When the follicle produces new hair cells, the old cells are pushed through the surface of the skin at a rate of about six inches per year.
The hair that a person sees is actually a series of dead keratin cells. Each follicle in its head has its own life cycle which can be affected by age, disease, and a number of other factors.

Peppermint has been used for health purposes for many years, and leading health experts believe that the ancient Greeks, Romans, and Egyptians, applied peppermint for a variety of health reasons thousands of years ago.
Peppermint in essential oil form is used in cosmetics and foods for its minty aroma, cooling effect, and perhaps even for hair growth.
Peppermint oil may cause a cold tingling sensation if it increases blood flow to the applied area. This may be the reason why essential oils aid hair growth.
How peppermint oil can help with hair growth
Peppermint oil is used in shampoos, detergents, bath products, makeup, and lotions. However, peppermint oil's benefits can only go beyond cosmetics.
Peppermint oil stimulates the scalp and hair follicles, but should not be used on those with dry scalp or brittle hair. Peppermint oil increases blood flow to the skin, which can help improve skin thickness, follicle count, and follicle depth.
