CezanneClassic Keratin Smoothing Solution 10 oz

This product is amazing! For reference, I have 4c low porosity hair, and my hair after this is incredibly defined and soft. I am so grateful to this vendor for making this product accessible, which has no formaldehyde.

I have been using this for years to keep my hair smooth and frizz free...my hair is long and very straight but tends to get puffy and frizzy. It doesn't work as great as a regular keratin treatment but the keratin chemicals made me very sick so I wanted something more organic and this smoothing treatment is the next best thing. I hope it continues to be available online as the process is very easy to do yourself at home.

Amazing product!!! Used on my 3B/3C curly hair and as promised zero damage. Process took about 2.5 hrs. Curls are more manageable and has an awesome shine! Definitely a fan!!!

Please be careful from this product its advertised formaldehyde free , but its contain Glyoxyloyl Carbocysteine that release the formaldehyde once the hair is heated ! These companies just keep hiding same dangerous Ingredients with similar once that the customer doesnt know yet .

I have been consistently straightening my hair with Keratin smoothing treatments for the past 15 years so I know a thing or two about the process. The last three times I used Cezanne with three different hair stylists. Since it purports to be formaldehyde-free, I knew it was not going to be as effective as the products with it. The first time, it was okay. It wasn't great, but it did relax my hair a little bit. The second time, the stylists didn't follow the exact procedure that I was familiar with and it did not work, so I attributed it to user error. The third time with a different hair stylist, we followed the exact instructions, but it still did not work. After the first shampoo, no change in hair texture from before the application. I know to shampoo only with sulfate-free shampoo so I did not shampoo out the product. This Cezanne product I purchased does not work. It was expensive so I am quite disappointed by the lack of results. I do not recommend it.

Like the product very much, healthier on the hair

I've been using this product for several months. My hair looks good when I first use it, but it doesn't last past the first wash afterward. After a few washes it is totally out. I'm using sulfate free shampoo and still after one wash my hair is back mostly to square one. This product is way too expensive given it's limited duration.
