    MAIN INGREDIENTS

    Dual-action formula, repairs hair and seals ends, uses antioxidant-rich and hair-strengthening raspberry extract.

    Enriched with a cocktail of essential oils—coconut, sunflower, olive, flax, avocado, and macadamia—that provide hydration, immediate shine, and softness to hair.

    Along with vitamins A, B, D and E that nourish the hair, improve its resistance and neutralize free radicals to prevent hair aging.

    -> Raspberry extract - strengthens and protects, while detoxifying and purifying hair.
    -> Natural oils - deeply moisturize the fibers and seal split ends
    -> Vitamins A, B, D and E - regenerate hair follicles, protect hair fibers from external damage and provide shine and softness to the hair.

    HOW TO USE THE PRODUCT?

    On wet hair as a reconstructor:

    1-> Apply 1-2 pumps on wet hair.

    2-> Comb through your hair to distribute the product evenly. (If you're applying it with the Hair Thickener, use the +Plus serum first to hydrate, and after a few minutes, the Hair Thickener to add volume.)

    3-> Do not rinse.


    On dry hair as a cuticle or tip sealer:

    1-> Apply 2 to 4 pumps to dry hair.

    2-> Spread in the palm of your hands and apply from the middle to the ends.

    3-> Comb and style according to your style. Do not rinse.


    Recommendation: Boost the results of the +Plus serum by incorporating the Glycolic Acid Mask into your routine. This intensive treatment deeply hydrates, gently exfoliates the scalp, and removes impurities, leaving your hair visibly softer, shinier, and healthier.

    For a thicker, fuller effect, complete your routine with the Hair Thickener, which coats each strand with plant-based proteins, creating a thicker, stronger, and more voluminous appearance from the first application.
