Skin Reactions and Skin Allergy tests

Introducing the “Skin Allergy Test” – a Necessity in Hair Coloring

Is it possible to have a skin reaction towards hair colorants?

Much like how some of us break out in hives from eating a specific food item, or how we might have an allergic reaction to certain drugs and cosmetics, the same may happen for hair colorants. Due to the substantial amount of dyeing chemicals present, hair colors might cause a skin reaction for some people.

Skin reactions to hair colorants are generally known as inflammatory dermatitis, and can be classified as either primary irritant dermatitis, or allergic contact dermatitis. Refer to the following to learn more about their differences.

Only in rare cases do allergic reactions occur. However, we strongly recommend that you conduct a skin allergy test (i.e. a patch test) prior to using a hair colorant.

Why do I have to do a skin allergy test?

Skin allergy tests help test for the possibility of an allergic reaction as a result of hair coloring.

Even if prior use of the same hair dye has not previously caused any reaction, your body may develop an allergy over time due to bodily changes. As such, it is strongly recommended to conduct a skin allergy test 2 days (48 hours) in advance, whenever you want to color your hair. In the case of a skin reaction, please seek treatment from a dermatologist immediately. Any delay in appropriate treatment will prolong the condition.
