Keep your hair smoother, softer, and easier to manage with Keragen Smoothing Shampoo and Conditioner. This sulfate-free haircare duo is designed for maintaining smooth-looking hair after a keratin treatment while helping reduce frizz and improve manageability.

The formula combines keratin, collagen, Panthenol (Vitamin B5), argan oil, and jojoba oil to provide gentle cleansing and conditioning without the heavy feel of some traditional hair products.

Why Use a Smoothing Shampoo and Conditioner?

Your regular haircare routine can make a difference in how your hair looks and feels after a smoothing treatment. Keragen Smoothing Shampoo and Conditioner provides a sulfate-free cleansing and conditioning routine designed for regular maintenance.

  • Provide gentle cleansing for regular use

The sulfate-free formula is suitable for all hair types, including color-treated and chemically processed hair.

Customer photo review of KERAGEN Smoothing Shampoo & Conditioner - Keratin & Collagen Infused Frizz Control System

I loved the way the product was packaged. It made me feel that the seller cared, knowing that this expensive product could spill. It was all good when I opened the conditioner, so difficult to open, which is good. My hands were getting slimy when opening the shampoo bottle. Some had spilled or it was packaged that way, which upsets me because it is an expensive product. I did not pay to receive 3/4 of a bottle of shampoo. not happy about this. The product is excellent. See pictures of my hair. My hair stylist used this product when I did keratin. I want to receive the amount of product I paid for.
