Symptoms of scalp eczema include red skin, stinging and itching, according to Mayo Clinic. Some people with seborrheic dermatitis may experience patches of greasy skin with flaky yellow or white scales on the scalp, ears, face or chest. This can also occur on the scrotum, armpits or other body parts.
While seborrheic dermatitis is a type of eczema that mainly affects the scalp, it can also affect the back, face, upper chest and other oily body parts, notes Mayo Clinic. It may cause stubborn dandruff on the scalp, eyebrows, hair and facial hair. Scalp eczema may cause eyelids to turn red or crusty.
If seborrheic dermatitis becomes excessively uncomfortable and interferes with sleep or daily tasks, a medical professional should be consulted, recommends Mayo Clinic. Other reasons to call a doctor include a suspected skin infection, feelings of anxiety or shame and a failure to treat the condition at home.
Scalp eczema is not a sign of bad hygiene, and it is not contagious, states Mayo Clinic. Treating scalp eczema can be difficult, and it usually requires medications and self-care steps. Being able to recognize the symptoms may help with managing them. Scalp eczema may return even after multiple treatments, and it tends to be a long-term condition.
