The Garnier Fructis Hair Filler Serum is specifically formulated to address the needs of weak, damaged hair. This advanced serum works to visibly reduce breakage and restore strength, leaving hair feeling fortified. It integrates key ingredients such as Vitamin Cg, Citric Acid, and a specialized Damaged Hair Repair Care Complex, which combine to reinforce the hair fiber from within. For those seeking a reliable solution, the Garnier Fructis Strength Repair Serum offers a targeted approach to hair rejuvenation, working to create a smoother, healthier appearance. This sulfate-free hair filler serum is designed to deliver comprehensive care to compromised strands. Inner Fiber Repair: This serum, when used as part of the complete system, actively repairs and strengthens broken bonds deep within the hair's cortex, the innermost layer of the hair fiber, promoting sustained resilience with continuous use. Outer Visible Transformation: Experience up to 79% stronger hair and a significant reduction of up to 4 times less breakage. This visible improvement contributes to a noticeably smoother and healthier hair texture when the full system is used compared to a non-conditioning shampoo. Advanced Formulation: The Garnier Fructis Hair Filler Strength Repair Serum is crafted without sulfates, parabens, phthalates, DMDM Hydantoin, drying alcohols, or mineral oil, ensuring a gentle yet effective treatment for damaged hair. Ethical and Sustainable Commitment: This product features a vegan formula, containing no animal-derived ingredients. The bottle itself is composed of 100% recycled plastic, excluding the cap. Furthermore, all Garnier products worldwide are officially recognized as cruelty-free under the Leaping Bunny Program by Cruelty Free International. Suggested Use: For optimal results, integrate the Garnier Fructis Hair Filler Strength Repair Serum into the 4-step strength repair system: Begin with the Bonding Inner Fiber Repair Pre-Shampoo Treatment, allowing it to remain on hair for five minutes before rinsing. Next, apply the Strength Repair Hair Shampoo and rinse thoroughly. Follow with the Strength Hair Conditioner, applying to wet hair and then rinsing.
