My baby also has a lot of hair and similar like yellowish skin colour, I assume it’s cradle cap
My LG had cradle cap until 10 months. I always intended to just leave it, but one night decided to buy the DermaFrida sponge, brush and comb set. I used this on her in the bath, and it all came out immediately. If yours is a bit tougher, you can also use Dentinox cradle cap treatment.
My baby has lots of hair and her cradle cap looks almost the same as this. It's coming looser now but it's so thick the massage combs never worked I've been gently using my finger tip to loosen a few bits away. It says it should go away on its own after 12 months xx
