What is the Sérum Filler Fondamental

È un siero riparatore anti-rottura e riempitivo che agisce con doppia azione:

1. Seals the cuticles, protecting the hair surface

2. Fills and strengthens the fiber from within, improving elasticity and strength

Sensitized hair absorbs more calcium from hard water, weakening the structure and cuticle. This serum protects against calcium damage, humidity and heat up to 230°C, keeping hair smooth, manageable and shiny.
