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.

Contact allergen

The culprit compound that used to cause allergy and present even in the most selling brands is known as paraphenylenediamine (PPD) or “contact allergen” or in scientific terminology, “sensitization dermatitis”. This ingredient is mostly found in oxidation and permanent hair dyes. If you know that you are sensitive to PPD, you should avoid such dye.
