Squamous conditions on the body and scalp are associated with excessively rapid epidermal cell renewal. The cells accumulate on the skin surface, creating scaly patches, which may be associated, in severe cases, with redness and itching. Opaque scales that look like thick dandruff appear on the surface of these patches.

Ducray dermatological Laboratories have formulated Kertyol PSO Kerato-Reducing Treatment Shampoo 200ml in order to provide effective action against all these factors:
- Micronized Sulphur, a recognized keratin-regulating active ingredient, works to reduce scaly patch thickness and helps eliminate flakiness.
- Salicylic Acid, a keratin-reducing agent, completes the action of sulphur acid in lifting dandruff off the surface.
- Ichthyol helps rapidly soothe rednesses and itching with long-lasting results.

With its gentle cleansing base, the shampoo is also well-tolerated and pleasant to use.

The complete formula of Kerytol P.S.O. Shampoo may be used alone or in association with specific dermatological treatments.

P.S.O. = Patches.Scales.Opaque.
