What's New in Contact dermatitis

What's new in dermatitis

I’m seeing an increasing number of patients with rashes behind their ears. As a dermatologist, my first thought is either a contact dermatitis (irritation or allergy) due to shampoo or conditioner versus seborrheic dermatitis (“dandruff”). The rest of the physical exam can usually point toward one of these diagnoses.

For patients I diagnose with a contact dermatitis, the chemical is often the official 2017 “Allergen of the Year” (voted yearly by the American Contact Dermatitis Society) of alkyl glucosides (ie, anything on the ingredients label that has the word “glucoside”). It is in many shampoos, conditioners, and cleansers. While overall allergy rates are about 2%, this is of course much higher in patients who see the doctor and have a rash behind the ears. Unfortunately, there is currently no widely available test to confirm the allergy as the most common test performed by allergists called the T.R.U.E. test does not include this compound. The allergen can be specially ordered and tested for, but this is uncommonly done by private allergists. I do not do this test and usually simply recommend avoidance and re-evaluation as the practical test.

The most common rash occurs behind the ears where the shampoo or conditioner drips from the thicker scalp skin to the thinner behind the ear skin. Dermatologists can treat the rash but the main potential cure is stopping the irritating shampoos and conditioners. Unfortunately, this is hard to do. The gentlest over the counter shampoo I recommend has tar which some people do not like the smell of. Regarding conditioners, due to the way they work, I do not know one that is reliably gentle.

If you have sensitive skin or other skin issues, please make an appointment for dermatology consultation at (626) 251-1500 to discuss your options.
