Introducing Kérastase Première Sérum Filler Fondamental, a leave-in repairing anti-breakage serum that enhances the resilience and gloss of damaged hair.
This cutting-edge serum is expertly formulated to address the unique challenges faced by over-processed hair, which tends to absorb three times more calcium from water than untreated hair, leading to significant damage both inside and out. Kérastase Sérum Filler Fondamental's lightweight, balmy texture performs a dual action: it seals the hair cuticles to protect the surface and fills the hair fiber, reinforcing its strength and durability. Ideal for anyone using styling tools, this serum shields hair from heat up to 230°C, combats humidity, and prevents frizz, leaving your hair supremely smooth and manageable. For comprehensive hair restoration, use this serum as part of a layered care routine with other products from the Kérastase Première range.
Apply on towel-dried hair.
