I am experiencing a serious scalp issue (since more than a year) that looks like a fungal or inflammatory infection. My entire scalp has developed thick white flakes that peel off in large pieces. It feels like a layered dandruff buildup. The scaling is persistent and keeps returning even after cleaning. I've attached photo of flakes and my scalp. I have already taken some treatments prescribed earlier by dermatologists, including: Ketanol Shampoo (2%) Itraconazole 400mg EG 20mg Tab Apiderm GM Cream Hatric 5mg Tab Candid Lotion Tarsyl Shampoo Despite this, there is no major improvement. I am not sure whether this condition is seborrheic dermatitis, psoriasis, fungal infection, or something else. I would like to know: 1. Is this likely seborrheic dermatitis or another condition? 2. What treatment or medications should I follow now? 3. Are there any effective home remedies or lifestyle changes that can help reduce the scaling?
