I understand your frustration. But you will need to visit an allopathic dermatologist. It seems by your complaint that you most probably have severe seborrhoeic dermatitis of the scalp (dandruff ) which will need prescription medicines. What you need to know is that it is treatable but it's a tendency and it recurs. Once you get it treated, ask the dermatologist to guide you on how to maintain the scalp and prevent it. It will help. http://www.skinmatra.com/single-post/2016/09/17/Listen-to-your-skin-talk-Here-is-how
