Babies often lose their hair during the first six months of life.
This is because hair alternates between two stages, a growing stage and a resting stage, and in newborns, all of the hair follicles enter the resting period at the same time, causing them to fall out. This hair loss is thought to be due to the natural drop in a baby's hormone levels right after birth. As he starts to move around more and when he stops his head-banging behavior, this type of hair loss corrects itself. Some babies not only lose their hair, but also when their new hair comes in it's a completely different color and texture. Julie Carlson's son Will was born with a full head of thick black hair.
