What Causes Dandruff
Dandruff is mainly caused by excess skin cell turnover on the scalp, often linked to a yeast called Malassezia. Other triggers include dry skin, sensitivity to hair products, and certain skin conditions like seborrheic dermatitis.
Key Shampoo Ingredients for Dandruff
Look for shampoos with proven active ingredients such as zinc pyrithione, selenium sulfide, ketoconazole, coal tar, or salicylic acid. These help reduce flakes, control oil, and slow skin cell growth. For stubborn cases, a dermatologist may recommend prescription-strength formulas.
How to Choose and Use the Right Shampoo
Select a shampoo based on your scalp type and sensitivity. For oily scalps, formulas with zinc pyrithione or ketoconazole work well. For dry scalps, gentle cleansers with salicylic acid can help remove flakes without stripping moisture. Apply the shampoo, massage it into the scalp, leave it on for a few minutes, and rinse thoroughly. Using it two to three times per week often improves results.
