Baby hairs at hairline

Quick question do baby hairs grow all over head but are mostly apparent around the temples and nape and hairline?

There are short vellus hairs that never grow up and there are hairs that are early in anagen that appear short. I have seen men who get good response from finasteride who show short anagen hairs that will eventually grow out once they have a few months of growth. There are also some short hairs that are at the end of their life and are frequently found in a hairline that is being lost through miniaturization. Is that what you are talking about with the term baby hairs?
