What does hair wellness® mean?

Hair wellness® is about nurturing the biological foundation that keeps hair growing strong and healthy over time. It’s a modern approach that combines scalp care and internal support for lasting scalp and strand vitality.

Why is hair longevity important?

As we age, hair naturally thins and weakens. Hair longevity focuses on slowing this process by nurturing scalp health and extending the lifespan of each strand, helping your hair stay resilient and healthy longer.

Our breakthrough technology includes plant exosomes and a liposomal peptide delivery system, which work together with plant-powered ingredients to enhance follicle function and extend the natural hair growth cycle.

How do you test your formulas for efficacy?

Our products are validated through clinical, consumer and placebo-controlled studies to confirm they deliver real, visible results for hair and scalp health.

Are your products clean, vegan and safe?

Yes. All our formulas are 100% vegan, cruelty-free and formulated without drugs or harsh chemicals. We prioritize clean, clinically tested actives that are safe and effective for daily use.

Are your products suitable for all hair types?

Yes. Our formulas are safe and effective for all hair types and textures. Whether you're looking to prevent future thinning or address visible signs of shedding and age-related changes, our plant-powered solutions are designed to support hair health at every stage.
