Red, itchy, blistery rashes on the skin can occur as a result of a contact allergy. Some patients note that certain perfumes, beauty products, hair color etc make them itchy hours to days after use.

Your allergist can perform a patch test to diagnose what chemical is causing this contact reaction.

In our office, we use the “North American 65 Extended Series.” (NAE 65) This test is painless and involves panels of “stickers” being applied to the back for 48 hrs. You would then return on 2 separate days for readings of the test. The NAE 65 panel tests for the top 65 most common contact allergens. Some examples are fragrance mix, chemicals found in hair color, nickel, preservatives in makeup/soaps/shampoos, etc.
