Keune Haircosmetics made Derma Exfoliate Shampoo to be tough on dandruff, but mild on your hair. When you’re diagnosed with dandruff, it means that you’ve got more of a naturally occurring scalp fungus than usual. This fungus kicks your scalp’s cell renewal process into overdrive, causing — you guessed it — dandruff. That’s where Care Derma Exfoliate Shampoo comes in. It contains octopirox, a substance that puts the fungus’ excessive multiplication to a halt and clears away visible dandruff flakes. The shampoo’s anti-bacterial properties relax the skin’s sebaceous glands, soothing your itchy, irritated scalp. The result: a scalp that works as it’s supposed to and lovely, healthy hair.
