Baby Hairlines

Why is it that when a baby’s hair is growing in, it starts with the pattern of the receding hairline? Thinner on top with a forelock and nothing at the temples?

On another note…is the hair at the temples and crown slightly thinner in even non balding people? I notice that women and children also seem to have lighter/thinner looking hair at the temples.

I just had my first grandchild on May 1st, and she was born with a Norwood class 4A balding pattern… so of course, the jokes ran around that we were going to transplant the new addition to our family. The proud daddy laughed and laughed. Over the course of 4 weeks, the hair loss pattern got better and now she almost has a full head of hair. I don’t have an explanation as to why some babies are born with less hair that quickly grows in, but it’s not uncommon. Some of my own kids were born with a gorilla look (hair-wise) instead of the class 4A pattern on my granddaughter. Don’t focus too much, as things in the hair side change rapidly in babies.

With regard to your second unrelated question, I don’t really see much of a difference around differing parts of the scalp, but hair in the very frontal hairline and the neck is often finer.
