Talk to Dermatologist on Fungal Infection On Hair

Need suggestions and recommendations from the doctors as well as from the people. We are really worried for our 2.2y old son, he got fungal infection in his hair and loose some part of hair from his head. Before that we didn't know it was fungal but after consulting Dr gohar Alam he cleared that it's a fungal infection. Well it's been 1 month and 7 days we followed the medicine and topical lotion recommended by the Dr gohar Alam but it's still there. Yesterday when we gave him bath, after drying of hair he produces a lot of dandruff, skin scalp, all over his head. He still had bald patches on his head. No hair growing from those part of the head where he shed hair. Please help me what should I do now. I'm sharing few pics that we took yesterday after bath. If anyone of you facing or your kid facing this kind of problem please share your experiences too. JazakAllah
