Kérastase Première Sérum Fondamental 90 ml

The Première Sérum Fondamental Filler is a leave-in serum that fills the hair, prevents breakage, and protects it from heat styling tools, leaving it shiny and strong.

Calcium in hard water can cause further damage to already damaged/weakened hair. Being more porous, damaged hair absorbs 3 times more calcium than natural hair and enters a cycle of persistent damage.

This serum provides a dual reparative action to the hair: its light and creamy texture seals the ends. This anti-frizz serum seals and plumps the hair strands, leaving hair shiny and strong. Hair is protected from excess calcium, humidity, and heat up to 230°C*.

Controls frizz for 72 hours* and leaves hair soft, supple, and easy to style. To provide extra care for your damaged hair, use the Sérum Fondamental Filler with the rest of the Première range.

Start your routine by layering the Concentré Décalcifiant Ultra-Réparateur and the Bain Décalcifiant Réparateur. Then apply the Masque Filler Réparateur or the Fondant Fluidité Réparateur to lengths and ends. Finish by applying the Sérum Fondamental Filler to complete your hair repair.
