Something i noticed, hair on children

I have some friends who have small children, both my friends children are boys one 5 the other 6 and as it is summer they run around without a shirt on to keep cool.

One thing i noticed was the hair on their backs, there seemed to be so much of it, you can see it glistening in the sun.

So it got me wondering are we born with a certain amount of hair follicles and have them for life, and well we do

It seems that a developing fetus has all of it's hair follicles formed by week 22.

There are 5 million follicles on the body.
One million of those are on the head, and 100,000 are on the scalp.

It is the largest number of follicles we will ever have - hair follicles are never added during life.

As we grow older and our body grows, and the density of the hair follicles on the skin decreases.

Who would have thought, isn't it strange what you find out about how the human body works.
