Dandruff, characterized by white flakes and an itchy scalp, affects nearly half of adults worldwide. While harmless, it can be embarrassing and persistent. Understanding its causes and adopting targeted treatments can help you achieve a healthier scalp. This guide explores the root causes, science-backed treatments, and actionable tips to combat dandruff effectively. 

What Causes Dandruff? 

1. Malassezia Fungus Overgrowth, This naturally occurring yeast on the scalp feeds on oils, sometimes triggering inflammation and accelerated skin cell shedding, leading to flakes. 

2. Dry Skin, Cold weather or dehydration can cause dry skin, resulting in smaller, less oily flakes compared to fungal-related dandruff. 

3. Seborrheic Dermatitis,   A severe form of dandruff marked by red, greasy skin covered with yellowish scales, often affecting oily areas like the scalp. 

4. Sensitivity to Hair Products (Contact Dermatitis), Harsh chemicals in shampoos or styling products can irritate the scalp, causing flaking and itching. 

5. Infrequent Shampooing and skipping washes allow oil and dead skin cells to accumulate, worsening dandruff. 

6. Diet and Lifestyle Factors,  Diets low in zinc, B vitamins, or healthy fats may contribute. Stress also weakens immunity, exacerbating scalp issues. 

7. Stress,  High stress levels disrupt scalp health, increasing oil production and inflammation.
