Hi it will go way , apply coconut oil every day and wash his head every day. Dont let the oil be on his head as it may invite dirt.

Yeah..on head
Earlier it was cradle cap,doc gave an ointment n it was cured
Now when his hair are removed,I found the patches again on head

On the head you mean right....Can you post some images...usually applying coconut oil will help ...No worries
