I had seborrheic dermatitis on my cheek. This year I realized the inflammation has spread to my scalp margin, forehead, nasolabial folds and external ear canal. Whats' the worst case for hair colour?

The hair dyeing products used in professional salons are very potent and thus can aggravate the scalp problem the most if you are sensitive to the chemicals in them. Do-it-yourself kits contain milder strengths of the same substances as salon products.
Tints are a one pack product that coats the hair for 1-2 washes and cause less scalp problems but require frequent washing and application.
Usually if a hair product is precipitating or aggravating a scalp/akin condition, it will appear as a definite margin between the normal healthy skin and the skin that got in contact with the product in question. If the problem is limited to the treated zone and stops at the margin between your hair & bare skin, then it is highly probable that the hair product you’re using is aggravating or even inducing your problems. Also the problem may be uniform across the whole dyed area of you scalp. You may need to wait up to a month after stopping the product for your scalp to recover.
