Even those who were born with a full head of hair may find that it is either getting thinner and falling out all over. Other babies just get a bald spot in the back of their head.
This hair loss in babies is usually normal and the hair will quickly grow back.
Telogen Effluvium
Telogen effluvium is the medical term that explains common baby hair loss. A baby's hair often enters a resting state that causes it to easily fall out. This also often happens to older children and adults after a serious illness like a severe infection, high fever or major surgery.Once your baby's hair enters a growth cycle again, the older, resting hairs are pushed out, making it seem like your baby is losing her hair.
Friction Alopecia
Another way that babies lose their hair is when they lie in the same position, especially flat on their back. These babies often rub the back of their head in their bed, car seat or swing. The friction of rubbing their head against these surfaces causes the hair to come out, creating small bald spots on the back of a baby's head.Fortunately, these bald spots quickly fill in with hair once the baby is sitting up, rolling over, and spending less time on her back.
