It called cradle cap for infant, which is similar to "dandruff" in older children.
You might try washing her hair less often, maybe every 5-7 days
If it does not help:
1)Use baby oil or olive oil to soften the thick crusts. Rub it in with your fingers, let the oil soak in for 15-30 minutes, then gently remove the crusts with a soft toothbrush. Wash the oil out immediately. This is very important, leaving the oil in too long can cause whole face of the baby to break out in a rash/>.
2)Antidandruff shampoo. Use an over-the-counter brand, such as Neutrogena T-gel. Be careful to keep it out of baby's eyes. After lathering it into baby's hair massage the scalp with a washcloth. Use it once or twice a week for about two weeks.
