My 2.5 month old had the worst cradle cap. Thick, dry , and scaly. I used this every 2 days when I gave him a bath and within a week and a half it is all gone and new hair is growing back so nicely, and his scalp is all healed and healthy. Follow the instructions use the sponge, then the brush and then comb out the crusty stuff. It worked wonders. I wish I had this with my firstborn who also had it. I also used regular Aveeno baby shampoo and body wash.
