My hair used to be very straight and very similar to that of my fathers, but then when i went through puberty it seemed to get curlier and curlier, and no one in my family has curly hair. Do the characteristics of hair change in some people during puberty? If so, it is in any way linked to the growth of facial and body hair that also occurs during that time?
I suppose the hair character can be a genetic trait that can change with puberty or change as your hormones change. You often see hair color change in babies — blond hair to brown hair, for example.
