Description

Keratin fibers instantly cover areas with low hair density, achieving a visual effect of greater volume and density, imperceptible to the naked eye.
Thanks to their electrostatically charged adhesion, they resist sweat, humidity, and wind. Enjoy long-lasting hold and flawless results, instantly transforming your look with a natural finish.

Choose your shade and enjoy visibly fuller, younger-looking hair.
    Main benefits

    Instant regrowth of sparse hair, ideal for concealing the appearance of alopecia. Available in 10 different shades. Won't stain or bleed, and won't clog pores.

    Easy to apply and remove. Long-lasting hold, until your next hair wash.

    (Some fibers may remain on your pillow when you lie down depending on the area of hair covered. Don't worry, shake it out gently to remove the fibers and add more fibers if necessary.)

    Boost your confidence with a 100% natural result.
    MAIN INGREDIENTS

    Formula with plant-based ingredients. Made with cedar resin and corn keratin.

    -> Cedar resin - improves the fibers' resistance to sweat and moisture.

    -> Corn keratin - hair-like texture. Provides natural highlights. Color-fast.
    HOW TO USE THE PRODUCT?

    1-> On dry, combed hair, apply the fibers to the areas with low hair density until the scalp is no longer visible.

    2-> Use the Keratin comb as a visor to prevent the fibers from falling on your forehead (optional).

    3-> Apply the multivitamin fixative for greater fiber hold.
