I had the honor of testing the Kérastase Première Sérum Filler Fondamental Hair Serum for free.
My first thought was that the container and packaging exude quality. The bottle feels sturdy and looks nice, which is great so you don’t have to hide all your products in a cabinet.
The consistency felt lovely, and upon application, my hair felt wonderful, but unfortunately, that’s where my positive feedback ends.
The serum was really not for me unfortunately. It has a very strong scent that is quite masculine, which was not at all a favorite of mine. Furthermore, I experienced that the serum had negative effects on my hair.
I have thin and fine hair with waves/curls, and even though the serum is supposed to be for all hair types and combat frizz, I just got more frizz and the texture of my hair flattened out, which made my hair look damaged. I didn’t get shine, softness, or reduced frizz, unfortunately.
Unfortunately, I think a serum in this price range should hold a higher standard, therefore I was extremely disappointed with the result, even though I tested the serum several times with different amounts of product each time. Now I just hope that my waves/curls return if I stop using the serum 💔
I am participating in a test panel and received a free test product.
