Cradle cap and hair loss!

Charlotte

My little boy is 4 months old... he has had cradle cap for a few weeks and since it has started coming away from his scalp it is taking his hair with it! :( he had a lovely head of hair when he was born and he now has bald patches all on top.

Anyone else going through this?? Anything else I can do to help? I’ve used cradle cap shampoos, oils and also gently brushing...
