Understanding Dandruff (Seborrheic Dermatitis) and Eczema:
Causes of Dandruff Eczema:
- Dandruff, also known as seborrheic eczema or seborrhea, often appears during adolescence or adulthood.
- The exact cause is unknown, but it is believed to be related to a fungus called Malassezia furfur, naturally found on the scalp and skin.
- Some people are more sensitive to this fungus or have larger amounts, leading to an eczema reaction.
- Dandruff can be intermittent, improving in summer and worsening in winter.
Symptoms of Dandruff:
- Common symptoms include flaky and scaly skin, along with itching.
- Scales may be yellow and oily or dry and white.
- Larger, yellowish flakes can be seen in the scalp, sometimes getting stuck in hair.
- On light skin, redness can be observed during eczema; it’s less visible on dark skin.
Affected Areas of Dandruff Eczema:
Dandruff eczema can appear in areas with many sebaceous glands, including:
- Scalp
- Eyebrows
- Around and in the ears
- Around the nostrils
- Chest
- Edge of the eyelids
- Armpits and groin
- Navel
Self-Care for Dandruff Eczema:
- Promote skin ventilation, avoid tight and warm clothing.
- Avoid wearing hats, especially on damp hair.
- Thoroughly dry long hair after showering.
- Use mild skin products that don’t irritate.
- Avoid hair products with alcohol, which can dry the scalp.
- Avoid oily skin products that can clog pores.
Treatment of Dandruff Eczema:
- Dandruff can be managed but tends to recur.
- For scalp dandruff, regular use of dandruff shampoos containing ketoconazole can help. Some also find relief with antifungal shampoos containing selenium disulfide.
- Prescription cortisone in liquid form may be needed if itching is severe.
- Creams with antifungal agents and cortisone can be used for dandruff problems on other skin areas.
