Questions? We've Got You Covered

This serum is formulated with 5 bioactive peptides and botanical extracts that help nourish the scalp, support follicle strength, and improve the look of hair density. It creates a healthier environment at the root for thicker, fuller-looking hair.

Most users notice their scalp feels more balanced and hair appears healthier within 3–4 weeks of consistent use. Visible improvements in thickness and density are typically seen after 8–12 weeks. Consistency is key for best results.

The serum is not a medical treatment for hair loss. Instead, it is designed to reduce shedding, support scalp vitality, and enhance the appearance of density by strengthening follicles and nourishing the root environment.

Yes! The lightweight, non-greasy formula works for all hair types and textures — from fine to coil. It absorbs quickly without leaving residue.

Unlike typical hair oils, this serum uses advanced peptides, antioxidants, and liposomal delivery technology to drive actives deeper into the scalp, targeting density and thinning at the root level.
