Dandruff and flaky scalp are often caused by an overgrowth of Malassezia fungus, seborrheic dermatitis, dry skin, or irritation from hair products. Other factors include stress, hormones, and certain medical conditions. Vichy Dercos products are formulated to address dandruff at the source and promote a healthy scalp.

Dandruff typically is caused by yeast overgrowth, causing larger, oily flakes. Dry scalp is due to lack of moisture, producing smaller, drier flakes. Dandruff often requires medicated products or active ingredients for treatment, while dry scalp can be managed with gentle, moisturizing products and nourishing hair care practices.

The Vichy Dercos Salicylic Acid Anti-Dandruff is designed for daily use between washes and can be applied up to 4 times per day.

The Vichy Dercos hair care collection combines a number of effective active ingredients to target dandruff including: micronized selenium sulfide, niacinamide, and salicylic acid. Our products are safe for sensitive scalp and color treated hair and can be used whether you have an oily or dry scalp.

Each of the Dercos products have recommended usage instructions including:

• Dercos Hair + Scalp Moisturizing Conditioner is recommended for use every 2-3 days
• Dercos Anti-Dandruff Shampoo is recommended for use every 2-3 days
