Hi Sir, I am 21 years old when I was 6 I developed psoriasis first it began with chicken pox than psoriasis evolved after some months. Since then I am having treatment. Though my psoriasis is mild but its all over my body except nails palms etc, but if I stop my medications for some time. My skin starts itching and I get flakes in form of small dots I have not yet found proper medicine or treatment for my scalp psoriasis. Suggest the best medication or treatment.
