KERASTASE PREMIÈRE SÉRUM RÉPARATEUR FONDAMENTAL Reparative and anti-frizz hair serum without rinsing for all damaged hair

Filler Fundamental Serum from the Première range is a restorative and anti-frizz hair serum without rinsing for all damaged hair.

Calcium in hard water can further damage already damaged/sensitised hair. Because it is more porous, damaged hair absorbs 3 times more calcium than natural hair, and enters a cycle of persistent damage.

This serum brings a double action to the hair: its light and creamy texture seals the scales of the hair to protect them on the surface, while filling the fiber to give back to the hair their strength and original fluidity. Your hair is protected from excess calcium, moisture and heat up to 230°C*. Frizz is controlled for 72H* and hair remains smooth, supple and easy to style. 

To give more care to your damaged hair, use the Fundamental Filler Serum with the rest of the Première range.  Start your routine with the superposition of the Ultra-Repairing Decalcifying Concentrate and the Repairing Decalcifying Bath. Then apply the Filler Repair Mask or the Fluidity Repair Fondant on the lengths and tips.  Finish with the Fundamental Filler Serum to complete your hair repair.
