Summary

This pilot study tests whether a daily plant-based serum can safely improve hair growth in 40 men and women with mild to moderate thinning hair. Participants apply the serum to their scalp for 9 months, and researchers measure changes in hair density and thickness using special cameras. The goal is to see if the serum is effective and satisfying to use, while monitoring for any side effects.

Active substance: Xtresse serum (plant-based extract blend)
What this could lead to: If it works, this could point toward a non-prescription serum to improve hair density and thickness in people with mild to moderate thinning hair.
What could go wrong: This is a small pilot study with only 40 participants and no control group. Results may not apply to everyone, and the serum may not work better than existing products.
