How Can seborrheic Dermatitis Be Treated?

Hello doctor,im Geetha...I was diagnosed with seborrheic dermatitis before 3 years and was given noskurf,steiprox,biotin,hairgro serum for a month.Problem seemed to disappear.I used to feel better .For nearly 3 months I m getting many boils all over my scalp and this time I was advised to use noskurf,steiprox for 2 months.Even after 2 months use,boils appear and what should I do to control it.Fed up with all chemical usage and hair fall for years,im going with home remedies like topical aloe Vera,curd.I have got patchy hair loss in areas of healed boils.What should I do now since my dermatologist advised to stop all treatment and go with dermadew shampoo twice a week and a mild shampoo like head and shoulders for daily use.How can I control my boils in scalp at present?is there no permanent solution to control seb derm?
