Whenever we talk about the allergy to the cosmetic products and skin sensitivity, hair dye allergies are the third most common allergies that come after fragrances and preservatives. Hair dying has become the most modern aesthetic trend among youngsters. It has also taken lead on the tattoos and body piercing.
Most of the hair dyes cause allergy resulting in burning, redness, and itchy scalp. This problem can be easily coped if treated early on; when you feel irritation in your scalp right after the implementing dye.
Unfortunately most of the people are unaware of the allergic reactions of hair dyes and they buy special shampoos and conditioners which may aggravate the condition instead of curing it.
