Understanding Red, Scaly, and Itchy Skin on the Scalp
Seborrhoeic eczema is a common skin condition that often appears as redness, scaling, and itching on the scalp or other sebaceous (oil-rich) areas. In babies, it’s known as cradle cap.
While medically harmless and non-contagious, it can persist or recur and cause significant discomfort.
Causes of Seborrhoeic Eczema
Seborrhoeic eczema is multi-factorial, meaning several factors contribute to its development:
-
- Increased sebum (oil) production
- Skin sensitivity and immune system involvement
- Stress, heavy sweating, or friction
- Yeast fungi (Malassezia), which naturally live on the skin but can overgrow under certain conditions
- Genetics and hormonal changes (e.g., puberty)
The condition is complex, and while the exact causes are not fully understood, these factors are known to play a role.
Symptoms to Watch For
Seborrhoeic eczema may appear once, chronically, or in recurring episodes, with symptom-free periods in between.
Typical signs include:
-
- Red, greasy, or tight-feeling skin
- Dry to greasy yellowish or white scales
- Intense itching, often worsened by scratching
Commonly affected areas:
-
- Scalp and hairline (dandruff may fall on shoulders)
- Face: eyebrows, between nose and mouth, beard area
- Other areas: nose, ears, forehead, chin, chest, body folds, diaper area in infants
Types of Seborrhoeic Eczema
Seborrhoeic eczema can appear in different body regions and at different life stages:
-
- Infants (Type 1 – cradle cap): Usually resolves on its own
- Adults (Type 2): May be chronic or recurring
- Classified based on body region, appearance, and origin
Treatment Options
Treatment focuses on relieving symptoms, controlling germs, and caring for the skin.
Skin Care Products
Shampoos, creams, or ointments containing:
-
- Tar, salicylic acid, selenium, zinc, or urea
- Tea tree oil or thymus peptide complexes
These help reduce scaling, soothe irritation, and support scalp health.
Medical Treatments (Prescription-Based)
-
- Topical antifungal agents – control yeast overgrowth (Malassezia)
- Corticosteroids – reduce inflammation
- Calcineurin inhibitors (e.g., tacrolimus, pimecrolimus)
- Antibiotics – for bacterial infections (topical or oral)
