Clinical trials

The goal of this clinical trial is to evaluate the efficacy and safety of two different formulations of a food supplement on hair health in healthy Caucasian male subjects aged 35 to 65 years with mild to moderate androgenetic alopecia. The main questions it aims to answer are: * Whether the two formulations improve hair growth and reduce hair loss after 42 and 84 days, as assessed by phototricogram parameters. * Whether the two formulations improve hair brightness, and colour lightness after 42 and 84 days, as assessed by spectrophotometer/colorimeter. Researchers will compare two active supplement groups and a placebo group to determine whether the active products improve objective hair parameters and perceived hair quality. Participants will: * be randomized to one of three groups : Active 1, Active 2 or Placebo; * take one capsule daily at breakfast for 84 days; * attend clinical visits at baseline, Day 42, and Day 84; * undergo hair assessments including pull test, phototrichogram, and spectrophotometer/colorimeter measurements; * complete a self-assessment questionnaire at follow-up visits; * be monitored for safety and tolerability throughout the study.
