KérastasePremière Anti-Frizz Reparative Filler Serum
Provides heat protection up to 230°C.* Up to 3x smoother hair*, up to 2x softer hair and up to 72-hour anti-frizz*.
Kérastase Première Repairing Anti-Frizz Filler Serum is a lightweight leave-in treatment which, when used with the Première routine, helps the inner repair** of all types of damaged hair and restores hair’s original strength***, leaving it glossy and supple.
Because of its increased porosity, processed hair can absorb up to 3 times more calcium from water than untreated hair, leading to a damaging calcium overdose which is noticeable inside and on the outside of the hair fibre. Kérastase Repairing Anti-Frizz Filler Serum has a dual action: its light, balmy texture helps seal the cuticles to shield hair’s surface, while coating the fibre to help fill external damage. Your hair is protected from the calcium damage of hard water, as well as from humidity, and heat up to 230°C*. Frizz is eliminated for up to 72H*, hair is left smooth and supple, and easy to style.
For even more care for your bleached or damaged hair, combine with the rest of the Première range. Try the power of the layering technique: start with the pre-shampoo treatment, Kérastase Première Decalcifying Repairing Pre-Shampoo Treatment, then without rinsing off the treatment, use the Kérastase Première Decalcifying Repairing Shampoo on top. Follow with the conditioner or mask before applying the Kérastase Première Repairing Anti-Frizz Filler Serum as a final repair step.

Go for it if you want silky soft hair
I bought this in the sephora sale. Its a repurchase. My hair is long, thick and frizzy. This adds smoothness and silky soft hair. Expensive but worth it !

Holy grail
This product is amazing. I have dry frizzy dehydrated hair, prone to breakage and you would think proteins would be a best friend but I really have to use them sparingly. On the other hand this product works wonders on my hair, I love to mix it with the premier oil, another big favourite of mine, and they just work wonders at soften and hydrating my poor ends.

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.

[This review was collected as part of a promotion.] My has become very frizzy since bleaching my hair for almost 10 years. Since using this, my hair is much less frizzy and looks much healthier.
