I noticed my son has a weak hairline at the temples. it’s hard to find information on the internet, but from what I gather, this could be his vellus hairs that will be replaced by terminal hairs at puberty.. Not sure if I’m being overly observant here, but I wanted to make sure it wasn’t an issue.
Hair lines are diverse and children’s hair line are no exception. Some babies are born without much hair and grow to have thick lush hair. Anything is possible and an overly observant parent may also be possible.
Follow up with your child’s pediatrician and express your concerns. There are other medical conditions that can impact hair as well. Please don’t let this last statement be a launching point for further Google search and a source for more confusion. The best advice is follow up with your doctor.
