Seborrhea capitis, commonly known as seborrheic dermatitis of the scalp, is a chronic inflammatory skin condition that primarily affects areas rich in sebaceous (oil) glands. It is characterized by greasy scales, dandruff, redness, itching, and irritation of the scalp. Although it is not contagious or life-threatening, the condition often follows a relapsing course and requires long-term management to control symptoms and prevent flare-ups.
What Are the Types of Seborrhea Capitis?
Seborrhea capitis is classified according to the age at which it occurs.
- Infantile Seborrhea Capitis (Cradle Cap): A common condition in infants characterized by thick, yellow, greasy scales on the scalp that usually resolves spontaneously.
- Adult Seborrhea Capitis: A chronic form that causes recurrent dandruff, itching, redness, and scaling of the scalp.
What Are the Symptoms of Seborrhea Capitis?
Symptoms range from mild dandruff to significant scalp inflammation and may extend to other oily areas of the body.
- White or yellow greasy scales on the scalp
- Dandruff
- Red, inflamed skin
- Persistent itching
- Greasy scalp
- Burning or irritation
- Scaly patches around the hairline
- Flaking involving the eyebrows, beard, ears, chest, or upper back
What Causes Seborrhea Capitis?
The exact cause is not fully understood, but several factors contribute to the development of seborrhea capitis.
- Overgrowth of Malassezia yeast on the skin
- Excess sebum production
- Genetic predisposition
- Stress
- Cold or dry weather
- Hormonal changes during puberty, pregnancy, or menopause
- Neurological disorders such as Parkinson's disease

When Should You See a Doctor for Seborrhea Capitis?
Seborrhea capitis is usually treated by a dermatologist. Individuals with severe, persistent, or treatment-resistant disease may also require evaluation by a primary care physician or other specialists if an underlying medical condition is suspected.
Consult a healthcare provider if you experience:
- Persistent scalp itching or irritation
- Severe dandruff that does not improve with medicated shampoos
- Painful or infected scalp lesions
- Hair loss associated with scalp inflammation
