What Causes Dandruff in the First Place?
Dandruff is more than just dry skin—it’s often caused by a combination of factors, including:
Overgrowth of Malassezia (a naturally occurring scalp fungus)
- Excess oil (sebum) production
- Scalp sensitivity or inflammation
- Disrupted skin cell turnover
👉 In simple terms:
Oil + Fungus + Scalp Imbalance = Dandruff
How Anti-Dandruff Shampoo Ingredients Work
Effective anti-dandruff shampoos are formulated to target the root causes of flakes and irritation. The best ingredients typically work in one or more of these ways:
- Antifungal – reduce yeast growth
- Keratolytic – remove dead skin buildup
- Oil control – balance sebum production
- Soothing – calm scalp irritation
