Première - Sérum Filler Fondamental Hair Serum

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.

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.

sleek hair

I received this product free from top box circle for my review. Using the whole line my hair has felt almost lighter and super soft. If you are not a fan of scents I would avoid this as it has a strong scent that lasts (for me that's a plus). For the serum you only need a small amount and it will smooth your frizz. Removed one star for price

A Must Try!

I enjoyed this more than i had originally imagined. This is my first hair serum product and it was surprisingly positive! The product smell nice, it was lightweight and it wasn't as gooey and sticky as i had imagined. My hair does feel healthier after integrating this serum into my routine. Would definitely recommend giving this a try if you have damaged hair. I received this product for free from Topbox Marketing for testing and review purposes.
