Hi greeting. How severe has seborrhoea been ? Please understand that seborrhoeic dermatitis is partly and inflammatory condition triggered by stress/fungal colonisation/oily hair/ oily skin type/ polllution / etc . It can be controlled and for practical purposes brought to remission. Maintenance shampoos may be needed sometimes. Seborrhoeic dermatitis is not a contradindication for hair transplant, however, reasonable control must be achieved prior to surgery. Please see a qualified dermatologist. If you are from Bangalore, you could see me with appointment - (details available on Practo Profile) or see any other qualified dermatologist of your choice. Warm Regards , Dr Govind Suresh Mittal, Excel Care Hospital / Roots Hair and skin clinic , Bengaluru
