go to your baby's pedia. he/she will prescribe a gentle formula for your baby. and don't use serum or anything that is formulated for adults. if anything, use natural like aloe vera leaf and gently rub it on your baby's scalp. and refrain from using shampoo everyday. even adults are advised not to used shanpoo everyday because it will just make the scalp and hair dry. 2-3 x a week will do.
