What should I use for these patches on my head? (Photo)

I have these strange patches on my head from last 4 months. I'm using Different lotions like zemetastone Tropical solution (minoxidil), Surbex Z Tablets, Hair Max Spray (minoxidil). And recently doctor recommend to use conaz shampoo. (Used for Scalp Fungus). Here my question is How can I prevent it and get my hairs back? I used Zemetastone for around 2 months and doc stopped it & let me use Hair MAX and Surbex Z Tablets. He also gave me K-kort Injection in early days to use it once in a month.
