A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

A total of 152 adults with hair loss will be randomized in a double-blind, placebo-controlled design to one of four groups receiving combinations of VitaGreen Capsule A, VitaGreen Capsule B, or capsule placebo together with VitaGreen Tonic or tonic placebo for 24 weeks. Participants will attend three in-person visits at which standardized hair counts, hair density measurements, and scalp photographs will be collected to quantify changes. Ten participants with gray hair from each group will undergo additional assessments focused on hair color changes. All clinical data will be systematically recorded for statistical analysis.
