Rashes are never fun, but they also don’t mean disaster every time. There are a wide array of rashes that come in all different sizes, shapes, colors, and textures, and each of them can indicate that different things are going on below the surface.

What IS a Rash?
It’s important to know that “a rash” is not a specific diagnosis; there are many types of rashes, and they’re typically a symptom of some larger issue. Infections that cause rashes may be fungal, bacterial, parasitic, or viral. The umbrella term “rash” refers to any sort of skin inflammation and/or discoloration that distorts the skin’s normal appearance.
To give you an idea of how unalarming rashes can be, know that common things like eczema, poison ivy, hives, and athlete’s foot are considered “rashes”. Having a rash doesn’t always mean the worse. However, it is important to figure out what type of rash you’re experiencing to get down to the larger problem.

Seborrheic dermatitis is the single most common rash affecting adults. It produces a red, itchy rash that characteristically affects the scalp, forehead, brows, cheeks, and external ears, although it can crop up anywhere on the body. At its essence, this rash manifests itself as severe dandruff and can be treated as such at home with medicated shampoos or moisturizers.
Newborns and adults age 30-60 are most likely to get this rash.

- Certain medical conditions/medicines
- Cold, dry weather
