Hair loss in newborn babies is completely normal and nothing to worry about. In fact, it is common for infants to lose hair during the first 6 months of life, a condition known as resting hair loss. There is an anagen phase and a resting phase. The growth phase lasts about 3 years and the resting phase is only about 3 months (resting phase is normal as long as it is within the time frame of 1 to 6 months). During the resting period, the hair remains in the follicle until new hair growth begins. Normally, there is always about 5% to 15% of the hair on the scalp in the resting phase, but emotional stress, fever, and changes in hormone levels can cause a large amount of hair to suddenly stop growing. Hair loss occurs after about 3 months when the hair enters the anagen phase again. Hair loss can occur when the hormone levels in your baby’s body drop immediately after birth. Mothers who have just had a baby usually lose a lot of hair for the same reason. If you notice bald spots on your baby’s head, pay attention to the position in which your baby sits and sleeps. If your baby always sleeps in a fixed position or likes to rest his head in the same position in the baby seat when sitting, then he will lose hair in the corresponding area of his head. Sometimes the back of the head can also become bald because the baby’s metabolism is strong and sweats a lot, and he always likes to rub his head on the bed when he sleeps. In fact, there are many newborn babies who have no hair at all and are little bald. Examine your baby’s scalp carefully, though, and you may find grayish, shaggy, extremely fine hairs. This sometimes lasts until the baby is a week old. You have absolutely nothing to worry about and enjoy the good old days of not having to care for your baby’s hair for a while!
