Key components include:

  • QUA-X Complex™ – a patented growth-support formula targeting the hair root environment
  • Peptides – help reinforce hair structure and improve resilience
  • Panthenol (Provitamin B5) – hydrates and enhances elasticity
  • Botanical Extracts – nourish hair for a healthier appearance

Full INCI lists are available on the individual product pages.

    FAQs

    When will I see results and what effects can I expect?

    Most users notice the first visible results after 3–4 weeks of regular use.

    The serum works in harmony with the natural growth cycle, which typically lasts 8–12 weeks, so full results develop gradually. With continued use, lashes & brows appear noticeably longer, thicker, and fuller, with improved density and overall condition.

    Can I use Qualash® and Quabrow® serums at the same time?

    Yes! These products are designed to complement each other and can safely be used together—Qualash® for lashes and Quabrow® for brows.

    How often should I use the serums?

    Use once daily, preferably in the evening, on clean and dry skin around the lashes and brows.

    Are these products safe for sensitive skin and eyes?

    Yes, both Qualash® and Quabrow® have been dermatologically and ophthalmologically tested. They are gentle and suitable for sensitive skin.

    Can I use the serum if I have lash extensions or microbladed brows?

    Yes, Qualash® is safe for use with lash extensions. Quabrow® can also be used after treatments like microblading, but it's best to consult your beautician if the treatment is recent.

    Will my lashes and brows fall out if I stop using the serum?

    No. The serum supports the natural lash & brow growth cycle and does not cause sudden lash loss when discontinued. If you stop using it, lashes/brows gradually return to their natural growth rhythm, without a rebound effect.

    Can I apply makeup after using the serum?

    Yes, but allow the serum to fully absorb (usually a few minutes) before applying makeup.

    Are the products vegan and cruelty-free?

    Yes, both products are cruelty-free and do not contain animal-derived ingredients.
