Naturally stiff bristles (bristles) will help fight cradle cap, which occurs in most babies between one and four months of age. The brush massages the baby's scalp, cleansing it of the cradle cap. Remember to use it together with an olive, for the best results - just brush the baby's head with the olive before bathing and then brush the scales. If this does not help, brush your baby's head with olive or greasy cream for a few hours.
