Product Description

Kérastase Première Sérum Filler Fondamental is a lightweight leave-in treatment for the inner repair of all types of damaged hair, leaving it glossy and supple.

Because of its increased porousness, processed hair absorbs 3 times more calcium from water than untreated hair, leading to a damaging calcium overdose which is visible inside and outside the hair fiber. Kérastase Sérum Filler Fondamental has a dual action: its light, balmy texture seals the cuticles to shield hair’s surface, while filling the fiber and reinforcing hair strength. Your hair is protected from the calcium damage of hard water, as well as from humidity, and heat up to 450°F. Frizz is eliminated, and hair is left smooth and supple, easy to style.

For even more care for your bleached or damaged hair, combine with the rest of the Première range. Try the maximum power of the layering technique: Start with the pre-shampoo treatment, Kérastase Concentré Décalcifiant Ultra-Réparateur, then without rinsing off the Concentré, use the shampoo, Kérastase Bain Décalcifiant Réparateur on top. Follow with the conditioner or mask before applying Kérastase Sérum Filler Fondamental as a final repair step.

Yummy
Flavor Name: Butterscotch
I'm very picky about taste, especially the coffee syrup. I have tried several and most do not even taste like the "name" on the bottle. I decided to try this one and it is so good, it tastes like butterscotch. Mmmmm The pump works fine and 2 squirts is perfect.

Tastes good
Flavor Name: Butterscotch
I like the butterscotch taste. It’s really good with caramel coffee. The pump isn’t exactly smooth so it splashes a bit. When you first insert the pump into the bottle, be sure the pump is twisted into the open position.
