Actually, hair doesn’t grow back, it just grows. Cutting or shaving the hair has no effect on its natural growth cycle. Depending on where it is on the body, hair grows about 1 cm per month. It goes through a growth phase, followed by a transitional phase and finally a resting phase before falling out of its follicle. Even though this process happens all over our body, we may not always be aware of it because we don’t really notice the hairs falling out unless we see them on our pillow or in the shower.
