Contact dermatitis is defined as an itchy, blistering skin rash brought about by direct exposure of the skin to certain substances. There are 2 variants of contact dermatitis – allergic and irritant. It is often hard to distinguish between the 2 types, but it is vital to make a distinction.
Close look on cosmetic-induced contact dermatitis
It is important to note that this cosmetic-induced condition is prevalent since many apply various chemicals to the hair, skin and scalp every day. Generally, the rash can manifest on the site where the product was dabbed on but sometimes the rash can form in another part of the body.
Remember that it is possible for an allergic reaction to a substance to arise even after years of using a certain product without any issues.
Fragrances
Contact dermatitis is often triggered by certain fragrances. The rashes might form on the neck in a manner where it was sprayed.
It is recommended to use products that are labelled as “fragrance-free” that can be tolerated by individuals who have the skin condition. Take note that fragrances might also be present in cosmetics, perfumes, conditioners, shampoos, fabric softeners, laundry detergents and moisturizers.
Preservatives
An allergy to different preservatives present in various hygiene and cosmetic products can also trigger contact dermatitis.
Hair products
Hair products are also a cause for contact dermatitis. The usual culprits include phenylenediamine in hair dyes, glyceryl thioglycolate and cocamidopropyl betaine.
It is likely for reactions to hair products to arise on the eyelids, face, back and neck before the scalp is affected.
Nail coatings
The reactions to acrylic coating on fingernails is the usual cause of contact dermatitis. A reaction is not only limited to the fingers but also on the eyelids and face.
