Première - Sérum Filler Fondamental Hair Serum

Doesnt work for me, its make my hair dry, i have natural straight long hair, but this makes my hair more dry and tangled

See no difference not worth the price , u could find better else where

Absolutely amazing!

I always regret trying Kerastase products because I absolutely fall in love with them and look past the heavy price point. This serum completely takes care of the frizz and makes my hair so soft and shiny. I can feel and see an immediate improvement as my hair starts to dry. I only tried a small sample but I will be buying the full size immediately!!

Must try. Very nice smell

WoW. I try that in the store my hair was very dry. Right away my hair looks soft feels healthy, and the smell the smell wow so good It is on my list now. To buy. It is also light weight cream feel to it.

Wouldn't buy again

Wasn't blown away by the product itself but was massively frustrated that due to the focus on the look of the packaging rather than function, there was a ridiculous amount of product stuck all round the sides and bottom of the metal container that you couldn't get out once the pump stopping working. A plastic bottle would've at least helped to squeeze it out. It's a big no from me.

Good product

I usually use Paul Mitchell and goldwell products, since I have bleached hair. This product works very well at reducing the frizz and holds it out for a bit. I would say it reduces about 94% of the frizz. So not all of it, but again I have a lot of breakage.

Not worth it IMO

Over priced, did nothing for me. I’ve had better results with many other more affordable brands. Too much hype. It has a pretty strong perfume smell, so I suggest you avoid if you’re sensitive.

Its not bad.

I only saw results using the whole line together. Using this with other products didn't give me the results I was hoping for. Not worth the price in my opinion.

A really good serum, I like it!!!

This serum is creamy and smells amazing. It leaves my hair soft and less frizzy. It definitely helps my damaged hair. I received this product for free from Topbox Marketing for testing and review purposes.

Your hair will thank you

I was super excited to try The Kerastase Serum Filler ,as I have thick long hair that I straigthen daily. I was looking for a long time for something to keep in my hair all the silkiness and shine. My hair has never looked so nice after years of daily straightening and styling. I would definitely recommend trying the Kerastase Serum Filler and will definetly continue to use.
