First of all, let’s get one thing directly: Dandruff is incredibly common and has nothing to feel embarrassed about it. Seborrheic is also known as dermatitis, dandruff is an inflammatory condition that makes the skin of the scalp red, dry and flashed. “When the weather becomes cold and dry, flares are common, and stress can also flare up,” says a dermatologist. Hadley King, MDShe notes that this type of dermatitis can also affect other areas, including the ears, eyebrows, facial center, eyelids, upper chest, upper back, armpit and waist area.

Dr. King says, “We do not know what is the reason for Seboria, but it seems multilateral.” “These factors may include a yeast that usually lives on our skin (more on it), our genes, a cold and dry climate, stress and overall health of a person.”

Some medical conditions may also increase your risk, including HIV, acne, rosesia, psoriasis, Parkinson’s disease, epilepsy, stroke, heart attack, alcoholism, depression and food disorders.
