Hair loss (Alopecia) is classified as loss of hair on your scalp or any area on your body. It can be the result of heredity, hormonal changes, medical conditions or a normal part of aging.
There are various active ingredients that help to stimulate the hair follicles to regain their activity, the most common being growth factors. Growth factors are specialised molecules that help to signal the cells in your body to fulfill a particular job. In the case of hair loss, they stimulate the follicles to receive more blood flow and nutrients, and in so doing stimulate the dormant hair follicles to “revive” themselves.
