What is Seborrhoeic Dermatitis?
Seborrhoeic dermatitis is a common skin condition that primarily affects the scalp, leading to dandruff and uncomfortable symptoms. It manifests as red, flaky patches and can occur on various parts of the body, including the face and chest. This condition often causes significant discomfort, as it can lead to itching and irritation.
Causes of Dandruff
Dandruff, a milder form of seborrhoeic dermatitis, is typically linked to an overgrowth of a yeast-like fungus called Malassezia, which thrives on skin oils. Several factors can contribute to its onset, such as oily skin, dry skin, and not shampooing enough. Environmental factors like stress and weather changes may also exacerbate this condition.
Treatment Options
While seborrhoeic dermatitis and dandruff can be bothersome, several effective treatment options exist. Over-the-counter dandruff shampoos containing active ingredients like zinc pyrithione, salicylic acid, or ketoconazole can help in managing symptoms. For severe cases, dermatologists may prescribe medicated creams or shampoos that reduce inflammation and combat fungal growth. Additionally, maintaining good scalp hygiene and avoiding hair products that can irritate the skin may also prove beneficial.

Seborrhoeic Dermatitis (SD) and Dandruff are two related conditions that affect the scalp and other oily areas of the body.
Seborrhoeic Dermatitis (SD)
Seborrhoeic Dermatitis is a chronic inflammatory skin condition characterized by:
- Redness and inflammation: Red, scaly, and inflamed patches on the scalp, face, ears, and other oily areas.
- Flaking skin: Yellowish, oily scales or flakes on the affected areas.
- Itching and burning: Itching, burning, or stinging sensations on the affected areas.
Dandruff
Dandruff is a milder form of Seborrhoeic Dermatitis, characterized by:
- Flaking skin: White or yellowish flakes on the scalp, often accompanied by itching.
- Scalp irritation: Mild redness and irritation on the scalp.
Causes and Risk Factors
- Overproduction of sebum: Excessive oil production in the skin contributes to the development of SD and Dandruff.
- Malassezia fungus: A yeast-like fungus that feeds on sebum and contributes to the development of SD and Dandruff.
- Hormonal changes: Hormonal fluctuations, stress, and genetics can contribute to the development of SD and Dandruff.
- Sensitivity to hair care products: Harsh chemicals in hair care products can irritate the scalp and contribute to SD and Dandruff.
Treatment and Management
- Medicated shampoos: Antifungal, antibacterial, and anti-inflammatory shampoos can help control SD and Dandruff.
- Topical corticosteroids: Creams or ointments containing corticosteroids can help reduce inflammation and itching.
- Antifungal creams: Creams or ointments containing antifungal medications can help control the growth of Malassezia fungus.
- Lifestyle modifications: Reducing stress, maintaining good hygiene, and avoiding harsh hair care products can help manage SD and Dandruff.
Prevention
- Regular shampooing: Regularly washing the scalp with a gentle shampoo can help prevent SD and Dandruff.
- Using gentle hair care products: Avoiding harsh chemicals in hair care products can help prevent irritation and inflammation.
- Reducing stress: Engaging in stress-reducing activities, such as meditation or yoga, can help manage stress and prevent SD and Dandruff.
- Maintaining good hygiene: Keeping the scalp and hair clean can help prevent the buildup of sebum and Malassezia fungus.
