After taking accutane for 6 months my is scalp not producing sebum at all, hair has become extremely dry n brittle, facing extreme hair fall since then, please help. Have gone through all the tests suggested by doctor n all the reports are fine (thyroid, vitamins,zinc, iron,etc). The only problem I could feel now is that there is no oil/sebum production in my scalp even if I do not wash my hair for 4-5 days, my hair stays super dry n keeps falling like anything. I have been taking really healthy diet since last year under guidance of a dietician and have been oiling my hair twice a week but of no use. Been to a doctor earlier who advice me some multivitamins plus biotin course for 3 months but nothing helped. The only issue here is no production of sebum in my scalp which no doctor here in my area could help with. Thanks in advance if anyone could help.
