The typical hair growth cycle for most people is about four to seven years. This is often where the thought comes in that your hair is brand new every seven years. Technically, it is because by this time, the hair has cycled out and new hair is growing.
Does hair really change every 7 years?
A single hair has a normal life between 2 and 7 years. That hair then falls out and is replaced with a new hair. How much hair you have on your body and head is also determined by your genes. Nearly everyone has some hair loss with aging.
Is it possible to regrow hair after years?
“If a follicle has closed, disappeared, scarred, or not generated a new hair in years, then a new hair wouldn’t be able to grow,” Fusco says. But if the follicle is still intact, yes, it is possible to regrow the hair—or to improve the health of the existing thinner hairs.

What is the lifespan of a hair?
The only “living” part of a hair is found in the follicle as it grows. The hair strand above the skin has no biochemical activity and so is considered “dead”.

Does hair loss go in cycles?
