I have been using these product the last 3 weeks. I am quite concerned about my hair, since I got 40 it is getting thinner and thinner, and falling down a lot. I noticed a great difference since the very first time. It is super nice to use, with a super fresh sensation, mint or peppermint, you realised your folicule hair is cleaned in depth. This makes it easier to grow new hair, as it breathes naturally. Love it! I definitely recommend it.

I have been using this product for a week and I can definitely notice a difference in the thickness and fullness of my hair. It works really well with the conditioner and does not leave my hair feeling heavy or greasy. Quite the opposite, my hair has felt much healthier since using this product.

I've just started to use Redken Cerafill Defy Shampoo as my hair is thinning having reached my mid-forties (early fifties!). It was very easy to apply and even after using it for the first time, the results were truly amazing! My hair has volume and every strand of hair appears thicker. I've used it a few more times since and the results just get better and better. Now i have the thick, volume-enfused hair I always wanted! I would highly recommend this product for those with thinning hair - or those who would appreciate more volume and bounce!
