We put olive oil on her head an hour before bath time. Then applied mustela cradle cap shampoo, let it sit for a few minutes and then used that comb Nikki posted. Was totally gone in 2 washes. Granted it wasn’t awful cradle cap but it felt like magic.
I put baby oil on my boys head once a day and after a bath. It keeps it at bay. Its still there as it becomes flakey if I miss a day but it keeps it under control
I tried to get the dentinox shampoo but it wasn’t in stock anywhere so I followed the baby oil method. I rubbed loads of baby oil into her small amount of hair about 45mins before her bath and then shampooed it. After the bath I pulled out the big flaky bits that were stuck in her hair and kept gently rubbing it with a towel to get more bits out. After 3 days it was much better and now she has none. Good luck x
