Girls, hello. My daughter is 7 months old and has seborrheic dermatitis. The doctor prescribed Fenistil gel. But it doesn't help. I also smeared Sudocrem and Bepanthen - there's no improvement. I read online that you can use shampoos like Nizoral and Dermazol. But can kids' heads be washed with them? Nothing is written about this. What do you think? Should I try? And maybe give me some tips on treatment methods? Because my baby is so uncomfortable, her scalp constantly scratches until bleeding, she cries, and she's just restless.
