Cradle cap or Eczema

Kadijah

So my son has really bad eczema over his body, and he has scales of dry skin in the lining of his hair and in the front/middle but nowhere else in his head. When I comb it out his hair comes out with it and now he has a bald spot so I'm scared to comb more out. Any products or shampoos for eczema if it is the case?
