Each human hair is contained within a follicle.

Your legs and armpits combined have a massive 78,000 hair follicles, and the exact number you have is determined by your genes. Thanks mum and dad!

Hair itself is not alive. Once the cells that make up a hair are made, they die and harden, forming the hair shaft.

Women’s hair is finer than men’s, but it’s still about as tough as copper wire of the same thickness.

The hair shaft is pushed up from
an opening
through the skin at an average rate of growth is 6mm per month.

Women’s total hair removal area is 18 times greater than men’s – 1690cm² for women vs. 95cm² for men. How unfair is that?
