My baby had cradle cap as well, I just used baby oil and let it sit for maybe 5-10 minutes and gave her a bath after and it started falling off in the water then just use a soft brush to brush the hair

My LOs doctor said to put plain yogurt on the head until it drys up and the wash it out and put coconut oil on. Then use a fine tooth comb and comb it out of the hair. Was gone in 2 days.

Honestly coconut oil works so well, be gone in a day or two, I use a fine tooth comb to get it off, ill stop after a few times so their head don't get sore, but coconut oil is awesome.

I used Elizabeth Parker natural cradle cap shampoo from Amazon and coconut oil.
