    MAIN INGREDIENTS

    A carefully designed formula with natural ingredients such as hydrolyzed soy, corn, and wheat proteins, combined with nourishing coconut, olive, and argan oils.

    Enriched with active ingredients such as niacinamide and panthenol, which help balance sebum production, protect hair from external aggressions, and provide deep hydration.

    In addition, it includes a vitamin complex with B3, B5, C and E, essential for strengthening the hair fiber and providing greater density to the hair.

    -> Niacinamide - controls oil production.
    -> Hydrolyzed proteins (Soy, corn and wheat) - improve hair density.
    -> Natural oils - soften hair fibers and prevent frizz.
    -> Panthenol - strengthens the hair structure and protects against external aggressions.
    -> Vitamins B3, B5 and E - nourish the hair, strengthen the hair fiber, stimulate healthy growth and provide shine and vitality to the hair.

    HOW TO USE THE PRODUCT?

    1-> Apply 1-2 pumps to wet hair from roots to ends.

    2-> Comb your hair to distribute the product evenly.

    3-> Do not rinse. If you apply the +Plus serum, use it first and after a few minutes, apply the Hair Thickener.

    Recommendation: If you have fine hair and are looking for more volume and density, start your routine with the Multivitamin Shampoo, which strengthens from the roots and leaves hair stronger, cleaner, and fuller.

    Then, apply the +Plus serum to add shine, softness, and seal the ends without weighing them down.

    Finish with the Hair Thickener, which envelops each strand to give instant thickness and a visibly thicker, fuller appearance from the first use.

    Your ideal routine for hair with more strength, texture, and movement.
