The Science of “Sebum Regulating” Scalp Purification
The Dercos Anti Dandruff DS (Oily) solves the problem of “Oily Dandruff and Rapid Greasing.” While dry dandruff falls easily, oily dandruff physically “sticks” to the scalp and hair roots. Vichy addresses this with a Triple Action Deep Clean System:
Selenium DS (Disulfide) Technology: This powerful active is physically engineered to target the Malassezia yeast. It physically prevents the yeast from over multiplying in the oily environment of the scalp, stopping the cycle of irritation and flaking.
Salicylic Acid Exfoliation: Infused with Salicylic Acid (BHA), which is oil soluble. It physically “breaks down” the oily glue that holds flakes to the scalp, ensuring that even “stuck on” dandruff is physically washed away.
Microbiome Balancing: This formula physically resets the scalp’s natural defenses. By balancing the ratio of bacteria and yeast, it physically ensures that dandruff stays away for up to 6 weeks after the treatment course is complete.
Key Ingredients & Benefits:
1% Selenium Disulfide: Physically destroys the cause of dandruff and prevents recurrence.
1% Salicylic Acid: Physically purifies the follicles and removes excess sebum.
Vitamin E: Physically calms the “burning” and itching sensations often found with oily scalp conditions.
Light Liquid Formula: Physically engineered to leave oily hair feeling “weightless” and refreshed.
Why Your Customers Will Love It:
The “First Wash” Miracle: It physically removes 100% of visible flakes starting from the very first application.
The “Fresh Root” Effect: It physically extends the time between washes by controlling the rate at which the scalp becomes greasy.
The “Clinical Scent”: It is physically formulated to smell fresh and clean, leaving no medicinal odor on the hair after rinsing.
How to Use (The Clinical Protocol):
Treatment Phase: Use 3 times per week for 4 consecutive weeks to physically “eradicate” the dandruff colony.
The “2 Minute” Rule: Massage into wet hair and let it physically sit on the scalp for exactly 2 minutes before rinsing. This is the time needed for the Selenium DS to “bind” to the scalp.
Maintenance Phase: Use once a week thereafter to physically “shield” the scalp from a relapse.
Pro Tip (The “Dual Wash” Hack): If your scalp is extremely oily, do a “pre wash” with a basic clarifying shampoo to remove surface grease. Then, use the Dercos DS as your second wash. This physically allows the active ingredients to reach the scalp directly without fighting through a layer of oil.
