It's been almost an year that i was diagnosed d problem of seborrhic dermatitis on scalp.Since then i have been taking homeopathic treatment. There has been much improvement in the scalp condition as the flakyt layer now is very thin as compared to the condition earlier when the layer of dandruff was very thick but after a certain point of time the llayer is as it is it is not reducing anymore and if i scratch it, it reappears again and again. Please suggest some medical help or some natural remedies for this.
