Before color treatment, is it necessary to conduct skin tests?

It will be safer to have an allergy patch test 48 hours before each color treatment. One simple method is to apply a small amount on the forearm and observe for local skin reaction. Parapheneylenediamine (also known as PPD) is the chemical that most commonly cause allergic reaction. Consult a dermatologist if in doubt.
