What is dandruff? Dandruff is a common scalp condition that occurs when the scalp sheds dead skin at an accelerated rate due to various factors. This scaly and flaky scalp looks untidy and unhealthy, thus affecting one’s self-esteem and confidence.

Research indicates that dandruff is more common in males, though it affects both genders. Its severity often peaks around puberty and may worsen in winter. Studies show dandruff sufferers shed significantly more hair—100–300 strands daily—compared to the usual 50–100 strands in individuals with healthy scalp.

What are noticeable signs of dandruff? Dandruff can be identified with some noticeable signs that can vary in severity.

Here are the major indicators:

• White, pale or yellow flakes on the scalp and sometimes eyebrows
• Persistent itching on the scalp
• Irritation and dryness on the scalp
• Redness without inflammation
• Thick scalp patches on the scalp
• Oily and greasy areas
• Hair thinning

These signs can vary from person to person depending upon the underlying cause of dandruff.

Possible causes of dandruff Dandruff can be caused by a combination of factors, including microbial infection, damaged outer skin layer and impairment of scalp skin barrier with different triggers.

These factors are explained below:

1. Microbial Infection: An overgrowth of Malassezia fungus on the scalp, exceeding normal levels by 1.5 to 2 times, is a major contributor to dandruff.
2. Dry Skin: A damaged outer skin layer (stratum corneum) loses moisture, leading to dryness and irritation, triggering dandruff symptoms.
3. Hormonal Changes: Increased sebaceous gland activity during puberty provides more food for Malassezia, leading to rapid fungal growth, itching, and flaking. 
4. Environmental Triggers: Excessive sun exposure, dust, pollution, and dirt can aggravate scalp conditions, causing flaking.
5. Poor Hair Care Habits: Over-shampooing or frequent combing can damage the scalp's protective barrier, leading to flaking.
6. Product Sensitivity: Harsh hair products with strong surfactants can impair the scalp's natural barrier, worsening dandruff symptoms.

How to treat dandruff?

Treating dandruff involves addressing symptoms like flakes and itching, tackling underlying causes such as fungal infections, and reducing recurrence with long-term care. Research shows that effective management often requires a combination of antifungal agents, good scalp care practices, and natural remedies. By combining these approaches, dandruff can be managed effectively.

Here are some widely used treatment options for dandruff:

• Topical Antifungal Agents Antifungal treatments help control the overgrowth of Malassezia fungus. Common antifungal agents in shampoos include Ketoconazole, Zinc Pyrithione, Selenium Sulfide, and Ciclopirox. Use antifungal shampoos 2–3 times a week, leaving them on the scalp for a few minutes before rinsing for the best results.
• Topical Keratolytic Agents These ingredients help remove flakes by breaking down dead skin cells. Examples include salicylic acid for exfoliation, coal tar to slow skin cell production and reduce scaling, and sulfur to loosen flakes for easier washing. Since these agents may cause dryness, follow up with a moisturizing conditioner.
• Scalp Hydration and Barrier Repair Agents Maintaining a healthy scalp barrier is essential to prevent flaking. Use moisturizing shampoos and conditioners containing ceramides and natural oils to restore hydration. Ingredients like niacinamide and glycerin support the scalp’s natural defenses and repair the barrier.
• Natural Remedies Natural remedies provide gentle and effective solutions for dandruff. Ingredients like tea tree oil, aloe vera, coconut oil, apple cider vinegar, and neem have antifungal and moisturizing properties. These help combat Malassezia, hydrate the scalp, soothe irritation, and reduce flakiness. Regular use of these remedies, combined with good scalp care, can effectively manage dandruff.

If dandruff persists despite these treatments, consult a dermatologist. Severe cases may require prescription treatments such as stronger antifungal creams, corticosteroids, or medicated shampoos.
