hello doctor. My scalp gives out damp and bad odor when ever I touch it. It often gets itchy and white dry flakes come out in finger nails some times and other times i get this greyish greasy susbstance in finger nails after scratching. Often time boils spread out around my head and most of the time they pop out around the crown area.
Significant hair thinning is also taking place at the moment.

Please note I had nodulocystic acne vulgris treated with roaccutane for 6 months couple of years back,.
Please advise
