Cradle cap HELP!

Julie

My son is almost 11 months old and has had really awful cradle cap since 3 months old. It’s so bad! Flaky, itchy, chunks of skin everywhere. I feel like I’ve tried everything: baby oil, coconut oil, all the shampoos, brushes, combs, and scrubbers. Help! I can’t believe he hasn’t grown out of this yet and I don’t know what else to do. The peds recommended selson blue, but I’d really like to keep it natural. Note: my son has moderate eczema and unfortunately can’t be bathed every day ☹️
