Dry, itchy coarse , ropey coiled crown hair.

Hi,I have a odd scalp, hair problem. I am a haidresser, not working with hair now, never heard of this. I burned my scalp, then it flaked, then it had follicle holes, hair grew back but hard to comb, no slip, and now there is like coils of hair growing in circle at crown, I can't get comb thru. It is so weird, and I tried antifungal stuff, dry hair stuff, anyone know what it is? Thanks Tweet
