Coloring your hair is an instant way to change the appearance, but hair coloring product also has some side effects. Allergy is the most common form of negative reactions happened after someone coloring his or her hair, and this often appears on facial skin. Dermatologists often find cases of people developing facial rashes, redness and itchiness days after they color their hair, and sometimes even when the people use the usual brand that never caused bad effects before.
Skin Allergy Causes from Hair Coloring
What can possibly cause facial skin problems and allergic reactions from coloring hair? One explanation is because facial skin is thinner and more sensitive than your scalp. Therefore, while hair coloring product works just fine on the scalp, your facial skin probably experiences way harsher effects. Also, allergic reactions can also happen when unnoticed scrapes or cuts make the chemicals in hair coloring seep through the skin and creating allergic reactions.
There are several common chemicals found in hair coloring products that can cause skin allergy, such as:
- Cocamidopropyl betaine. This substance is derived from coconut that is commonly found in various hair products, such as hair coloring products, shampoo, and conditioner. If your hair coloring product and hair products contain the same substance, it can cause harsh allergic reactions.
- This substance is commonly found in hair coloring that has light and medium brown shades, and can cause allergic reactions on some people.
- Para-Phenylenediamine. Also called PPD, this substance has actually been banned in some European countries, but it is still used in many hair coloring products outside Europe because it is effective and easily seeps into the hair follicles.
- Glyceryl thioglycolae. This is actually not a substance in hair coloring products, but in solution for making permanent waves. Allergic reactions can happen if some people use hair coloring products together with wave solution that contains this substance, which later creates chemical reactions that trigger allergy.
These substances are commonly found in hair product, but some people can experience allergy on their facial skin after using products with these chemicals.
Symptoms of Facial Skin Allergy
Allergic reactions on facial skin after using hair coloring products usually do not occur after several days since the last time you color your hair. However, some people experience the symptoms after weeks since the last time they color the hair. Common symptoms include red, flaky rash, itchiness, and facial swelling (usually only on one side of the face). The symptoms often occur on spots such as eyelids, neck, ears and forehead.
If you just color your hair and experience skin allergy symptoms on your face, neck, forehead and eyelids several days or weeks afterward, do not diagnose yourself and go to the doctor for diagnosis and treatment. If necessary, bring your hair coloring product and show it to your doctor, and explain your hair treatment rituals during the past several weeks or days. During the period, stop using harsh hair products or coloring your hair to prevent more skin allergy symptom breakout.
