Does the human body keep generating new follicles throughout life?
By week 22, a developing fetus has all its hair follicles formed about 5 million, of that 100,000 are on the scalp. We do not generate new hair follicles anytime during the course of our lives. This is the largest number of hair follicles a human will ever have. The density of scalp hair is reduced as we grow from childhood to adulthood. The reason is our scalps expand as we grow.
