Fructis Hair Filler + Polypeptide Hair Thickening Spray FAQs

  • Yes, hair thickening spray can work on all hair types, though it’s especially effective for thin or weak hair. Garnier Fructis Hair Filler + Polypeptides Fullness Repair Thickening Spray uses polypeptides to strengthen the hair fiber and citric acid to smooth and add shine, making it suitable for straight, wavy, or curly textures. While those with fine hair will see the most visible lift and volume, all hair types can benefit from the lightweight fullness it provides.
  • Hair thickening spray works by coating each strand to create the appearance of denser, fuller hair. The Garnier Hair Filler Thickening Spray combines polypeptides, which reinforce the inner fiber for strength, with a lightweight conditioning formula that adds lift and body without stiffness or residue.
  • Garnier Fullness Repair Thickening Spray typically lasts until your next wash. The overall effect of the Hair Filler + Polypeptides system builds over time, and while one use provides visibly fuller hair, the full benefits of the Hair Filler line become more noticeable after consistent use of the regimen.
  • While dry time for Hair Filler + Polypeptides Fullness Repair Thickening Spray can vary depending on hair thickness and whether you air-dry or use heat tools, most users find it blends in easily and sets without leaving residue. For faster results, apply before blow-drying to help lock in volume and fullness.
  • You can use Garnier Hair Filler + Polypeptides Fullness Repair Thickening Spray daily or whenever you style your hair. Because the formula is sulfate-free, silicone-free, and lightweight, it won’t weigh hair down or cause buildup.
