Rich, cleansing treatment

This intensive hair treatment is designed to replenish weakened, damaged hair with a “hair filler” approach, delivering concentrated nourishment where hair needs it most. Formulated with the patent-pending Hair Filler™ complex and low-molecular proteins, it helps fill both the surface and inner structure of the hair, including gaps in the cuticle, to strengthen strands and reduce progressive damage.

The rich balm-textured formula is silicone oil–free and focuses on absorption rather than heavy coating. When pressed onto damp hair after shampooing, especially toward the ends, it leaves hair feeling noticeably smoother, stronger, and more resilient. The formula is designed to help maintain softness and shine for up to 48 hours after use.

With a fresh floral herbal citrus scent and a non-greasy finish, this treatment is suitable for daily or intensive care. It is especially recommended for hair damaged by coloring, perming, or frequent heat styling, as well as for thinning or weakened hair that lacks strength and elasticity.

Ingredients

Hair Filler complex and low-molecular proteins help support smoother, stronger-feeling hair with less roughness.

This treatment uses a hair-filler approach, which means it focuses on replenishing weak or porous areas so the hair feels denser, smoother, and stronger after washing. Low-molecular proteins are relevant because they can coat and condition the damaged parts of the fiber more evenly, helping reduce the rough, hollow feel that comes with repeated styling or chemical stress. The silicone-oil-free balm texture also matters. Instead of relying only on a surface coating, the formula is positioned around absorption and close contact with damp hair, especially through the ends where damage tends to collect. That can make the result feel softer yet less heavy. The scientific rationale is cosmetic reinforcement: support elasticity, improve surface smoothness, and help hair hold onto a healthier feel between washes. With repeated use, damaged strands tend to look more controlled, less frizzy, and better able to withstand daily grooming. That makes the formula especially useful for regular use when the goal is a smoother, healthier-looking result.
