Seborrhoeic Dermatitis Diagnosis and Treatment in London
Seborrhoeic dermatitis is a common, chronic skin condition that causes red, flaky, greasy patches, most often on the scalp, face, and chest. It is related to an overgrowth of yeast on the skin and tends to flare in cold weather or times of stress. While not contagious or dangerous, it can be uncomfortable and persistent. At Skinhorizon Clinic London, we provide personalised treatments to control seborrhoeic dermatitis, relieve itching, and improve skin health.

Seborrhoeic dermatitis is a chronic inflammatory skin condition that often affects oily areas such as the scalp, sides of the nose, eyebrows, ears, and chest. It can vary from mild dandruff to more pronounced red, scaly patches that cause discomfort and embarrassment. The condition tends to relapse, particularly in colder months or with stress.
Causes and risk factors
The exact cause of seborrhoeic dermatitis is not fully understood, but contributing factors include:
- Overgrowth of Malassezia yeast on the skin
- Excess sebum (oil) production
- Genetic susceptibility
- Stress, fatigue, and cold weather
- Underlying conditions such as Parkinson’s disease, HIV, or weakened immunity
Symptoms of Seborrhoeic Dermatitis
- Greasy scales and flakes (often yellowish-white)
- Red, inflamed skin underneath
- Itching or burning sensation
- Crusting in severe cases
- In infants, thick yellow scales known as cradle cap
Seborrhoeic Dermatitis Diagnosis
Diagnosis is usually made by clinical examination. In rare cases, a skin biopsy may be used to rule out psoriasis, eczema, or fungal infection.
