Hair develops and grows inside a hair follicle. The follicle has a growth centre called a dermal papilla which sucks up nutrients and constantly creates cells that push up out of the skin. It’s this constant biological process that makes hair grow.
- Hair grows at about 1-1.5 cm per month
- After 3-7 years the follicle dies, letting the hair fall out
- Normally you lose 100-150 hairs each day
- Follicles then regenerate and grow new hair
Your scalp is full of follicles at varying stages of this cycle ensuring continuous and even hair growth.
