Kérastase Sérum Réparateur Fondamental Damaged hair 90 ml

The Essential Filler Serum from the range Premiere is a leave-in, reparative, anti-frizz hair serum for all types of damaged hair.

The calcium in hard water can cause further damage to hair that is already damaged or sensitized. Because it is more porous, damaged hair absorbs three times as much calcium as healthy hair, leading to a cycle of ongoing damage.

This serum offers dual action for your hair: its light, creamy texture seals the hair cuticles to protect the surface, while replenishing the hair shaft to restore its strength and natural smoothness. Your hair is protected from excess calcium, humidity, and heat up to 230°C*. Frizz is controlled for 72 hours*, and hair remains smooth, supple, and easy to style.

To provide extra care for your damaged hair, use the Essential Filler Serum along with the rest of the Première line. Start your routine by layering the Ultra-Repairing Detoxifying Concentrate and the Repairing Detoxifying Treatment. Then apply the Repairing Filler Mask or the Repairing Fluidity Treatment to the mid-lengths and ends. Finish with the Fundamental Filler Serum to complete the repair of your hair.
