Kérastase Première Sérum Filler Fondamental 90ml

The Sérum Filler Fondamental Repairing Anti-Frizz Serum is a must-have for anyone battling frizz or seeking a product that repairs and smooths hair effectively. Highly recommended!

This product makes your hair stronger, thicker. Holy Grail of hair serum

This serum is worth every penny! I blow dry my hair so much since I am an executive. This recover my hair so much! Thank you Kerstasae

Really makes the ends smooth , love it, would purchase again

Helps with the frizz after blow dry but hair feels rough

Decided to give it a try and it has become a staple in my styling routine. I have purchased other products that get rid of frizz but made my hair dry. This serum does not make my hair dry and does not allow frizz, plus it smells divine.

This product on wet hair after shampoo and conditioner works so well. I have bleached hair and this helps with smoothness and breakage.

Even not needing a lot of product I finished my bottle rather quick because I used it after every single wash! It helped my hair so much that I came back to buy more! Highly recommended, specially if you dry your hair a lot!

This product left my hair soft and shiny. The only thing I wish is a different bottle because I feel like there was a lot left but it’s too hard to get it all out.

I am not a fan of this product. It makes my hair look and feel dry. I love other products but this one doesn’t work for me.

This serum does exactly what it says, it literally tames frizzinedd hair. I apply it after the shower n comb it out. It doesn’t feel sticky, it literally makes your hair super soft nd tangle free once your hair dries

YES! I really liked this product and saw a big difference in my hair when it finished! WHile using this product my hair was much smoother and not as frizzy as it is now

The first time I used this product, noticed a huge difference in my hair. My hair is over processed due to color, highlights and Brazilian so it’s not in great shape. This product left my hair feeling super soft, shiny and healthy. I have tried everything but this will be my last. I can’t wait to try the other products in this line.

Significantly helped my frizz, must have if you have curly hair.

What a great product, this is an excellent formula, it help you with frizz hair and it gives you a shiny hair

This is a great serum to use for pre styling, I use to blowdry my hair and it's great, smells amazing.

Really new and innovative hair serum. I cannot even describe how it fixes every single issue with my hair, without weighing it down. Makes it beautiful and manageable. Smells great.

I like how it leaves my hair. My hair tends to be fluffy and gets burned a lot by the machine. Since I started using it, I have less frizz and less volume. It helps my straightening last longer.

So I was so hopeful that this product would make a difference since I have high confidence in Kerastase products. Honestly, it didn't and I felt that it may have made my hair a little drier.

I tried this first with a sample, and fell in love with it. I use it every time I wash my hair, it helped a lot this past summer.

I have tried my fair share of hair serums and nothing has helped as much as this one. This serum is light and absorbs into my hair easily, without making it look oily. My usual dry, frizzy ends are now smooth and tamed. I can already see my growing hair looking much healthier and nourished. I am definitely impressed. A plus side? This serum smells wonderful!

First time using this product and very happy to try it, my hair is so soft!

I used this serum on damp hair and blow dried. It seems to cut the drying time down and I am left with a light, shiny, smooth style!

The holy grail. Wish I had discovered these products years ago when menopause started.

I have had a problem with frizzy hair lately. Tried this product and it has made a huge difference, plus it smells great!!

This product has helped my hair in the shower with the water damage. Even with a filter shower heads my hair has had issues. This product has done wonders.
