Red itchy scalp. Cure in homeopathy?

Shifted to mumbai in 2017 March. have had a problem of extreme itchy scalp in my hometown Varanasi as well. but in July 2017 I could feel intense irritation on my scalp and sudden excessive increase of dandruff on my clothes. my scalp got so itchy that blood used to come out as i scratched my head. then I realised few areas of my scalp getting red and patchy(scaly). I could see it getting spread to my forehead and back neck as well. I m cleanliness freak. then I could feel the same irritation and dry skin near to my genitals. since Dec mid I am using candid B lotion and cannesten lotion to cure them. but I think they r temporary cure n not permanent. my hair is getting grey as well due to using some chemical medicated shampoos. because of the hair getting too dry after using those dandruff shampoo, I had to use other shampoo nd conditioner as well. so I have been using Moroccan oil shampoo and conditioner. so is there any permanent cure in homeopathy?? pls help me..
