Hello guys I have been suffering from seborrhoeic dermatitis for four years. It is on my scalp, behind my ears , inside my ears and around my nose. I have visited many dermatologists and their prescriptions give me relief for some time but it does not go away completely. The flakes are big ,dry and there is redness and itchiness. The shampoos I have used are Nizoral, Dercos, Sunshine Blue, T-Jel. If I remove my hair completely, it gets better. When my hair grows back, seborrhoeic dermatitis is back also. Is MCT oil good for this? Kindly recommend a good shampoo.
