Can anyone help me with my poblem of an itchy, red scalp. I have had the patch test and am allergic to Balsum of Peru, Frangrance Mix #6 and Nickel. I don't know what kind of shampoo or conditioner to use. Maybe I am not using it long enough as if in 3 days, I don't see results, I stop using it. The dematologist says I have excema (no psorasis or fungus, or dandruff). My scalp is red, itchy and dry. One area if whitish like dandruff. I also had a biopsy taken and blood work. No throid problem. Please, please help. I am at my wit's end and this has been going on for a year. Is there a shampoo and condition that I should be using that doesn't have benzoates in it. My face cream has benzoates in it and my face is clear as can be. My scalp is the problem which makes me wonder if it is the shampoo or conditioner. Any help thanks.
