Seborrhoeic Dermatitis & Dandruff: Causes and Solutions

Seborrhoeic dermatitis is a common skin condition that causes itchy and flaky skin, often appearing on oily and hairy areas of the body. Characterised by redness and scaling, this condition affects approximately 4% of the population. Understanding its causes, symptoms and treatment options is crucial for managing the condition effectively.

Commonly occurring as dandruff on the scalp, seborrhoeic dermatitis is a chronic inflammatory skin condition associated with an overproduction of sebum. This excess sebum creates an environment that encourages the growth of a fungus known as Malassezia, which is naturally present on the skin. When sebum levels rise, Malassezia can multiply excessively, leading to an imbalance in the skin’s microbiome. 

This overgrowth triggers an inflammatory response, causing irritation and skin redness. This results in increased flaking and shedding of skin cells, which presents as visible dandruff. Effective management of seborrheic dermatitis typically involves controlling sebum production and the growth of Malassezia to restore scalp health and reduce symptoms.

Possible Causes of Seborrhoeic Dermatitis

While the exact causes of seborrhoeic dermatitis remain unclear, several factors may contribute to its onset:

1. Natural Aging: As we age, changes in oil production can make this condition more likely to develop.
2. Hormonal Imbalances: Fluctuations in hormones can lead to increased oil production, providing a fertile breeding ground for Malassezia.
3. Skin Conditions: Conditions such as eczema or psoriasis can exacerbate seborrhoeic dermatitis.
4. Stress: Increased stress levels can trigger or worsen the condition.
5. Nutritional Deficiencies: Lack of essential nutrients such as zinc, iron and B vitamins can worsen the condition.

 Main Symptoms of Seborrhoeic Dermatitis

The primary symptoms of seborrhoeic dermatitis include:

• Red, inflamed patches of skin
• Flaky, white or yellowish scales
• Itching or burning sensations
• Oily skin and hair.

Bioxcin Aqua Thermal Intensive Anti-Dandruff DS (Dermatological Shampoo) is expertly formulated to effectively manage seborrhoeic dermatitis and combat dandruff. This powerful shampoo combines the unique benefits of mineral-rich thermal water with potent active ingredients such as Piroctone olamine, zinc, salicylic acid, glycolic acid and probiotics, making it a holistic solution for your scalp health.

Key Ingredients and Their Functions:

1. Thermal Water:
   • Enriched with essential minerals, thermal water soothes and hydrates the scalp, promoting a healthier environment for hair growth. Its unique composition helps reduce inflammation and improve skin barrier function.
2. Piroctone Olamine:
   • This antifungal and antibacterial agent effectively targets Malassezia fungi, a major cause of dandruff. By inhibiting its growth, piroctone olamine significantly reduces the risk of dandruff formation and associated scalp irritation.
3. Zinc:
   • Zinc plays a crucial role in skin health, promoting the healing of irritated skin and supporting the immune system’s response to fungal infections. It helps maintain the natural balance of the scalp, reducing microbial growth and inflammation.
4. Salicylic Acid:
   • Known for its exfoliating properties, salicylic acid helps to remove dead skin cells and reduce flaking. It unclogs hair follicles, preventing build-up that can lead to dandruff while promoting a healthier scalp environment.
5. Glycolic Acid:
   • This alpha-hydroxy acid (AHA) aids in exfoliation and improves skin texture by breaking down the bonds between dead skin cells. Glycolic acid also enhances the penetration of other active ingredients, maximising their effectiveness.
6. Probiotics and Vitamin B6:
   • Probiotics support a balanced scalp microbiome, strengthening the skin’s natural barrier and promoting overall scalp health. Vitamin B6 helps alleviate itching and irritation, providing relief for sensitive scalps.
7. Niacinamide:
   • This powerful ingredient helps balance oil production, ensuring that the scalp maintains an even condition. Niacinamide also has anti-inflammatory properties, further supporting scalp health.

Step-by-Step Usage Instructions

1. Wet Hair: Thoroughly wet your hair before application.
2. Apply Shampoo: Massage a generous amount of shampoo into your scalp, allowing it to foam.
3. Leave On: Leave the shampoo on your scalp for at least 3 minutes to allow the active ingredients to penetrate effectively.
4. Rinse: Rinse thoroughly with water. If necessary, repeat the application for added effectiveness.
5. Frequency: Use the shampoo three times a week for a maximum of three weeks. Avoid using it for more than three consecutive weeks to maintain the scalp’s natural microflora.
