Seborrheic dermatitis symptoms include red or crusty eyelids, dandruff, red skin, greasy skin patches covered with yellow or white scales or crust and possibly itching or stinging, according to Mayo Clinic. Infants with seborrheic dermatitis have crusty brown or yellow scales on the scalp, according to WebMD.
Infants with seborrheic dermatitis may also have a rash, according to WebMD. Seborrheic dermatitis in babies is often called cradle cap. It commonly occurs in infants 3 months old or younger and generally disappears before infants turn 1 year old.
Seborrheic dermatitis may appear on an individual’s face, buttocks, groin, on the skin folds under the legs and arms or around the navel, according to WebMD. It may also appear on the scalp, armpits, ears, chest or other areas of the body, according to Mayo Clinic.
Seborrheic dermatitis is a common skin condition, and it is not contagious, according to Mayo Clinic. Because it can look similar to other skin conditions, seeing a dermatologist for a proper diagnosis is sometimes necessary, according to WebMD.
Professional medical treatment of seborrheic dermatitis is advised if the skin appears to be infected, the discomfort interferes with sleep or daily activities, self-care is unhelpful, or the condition is causing anxiety or embarrassment, according to Mayo Clinic.
