It’s a bit embarrassing, but I don’t have much hair on the back of my head. It is quite common with babies during their first year. It usually comes from them rubbing their head when they sleep. I’ve been sleeping on my tummy every night for about a month so I hope my hair decides to grow back. Until then, I just have to cover it up with my top hair. If I don’t, it looks like I’m wearing a hair piece.
