I have a smelly scalp and I been told that I have a fungas infection or overactive sweat glands on my scalp. Would any selsun blue shampoo help me?

Need prescription rx. If you have fungal infection in the scalp it needs to be checked and treated with prescription meds and shampoo may also help.I may be a good idea to consult a dermatologist to make a correct diagnosis and proper treatment plan.
