Efficacy and Safety of a Drinkable Nutraceutical for Hair Loss in Patients Using GLP-1/GIP Receptor Agonists

The purpose of this clinical trial is to evaluate the efficacy of Olistic© Next Women, a nutraceutical supplement, compared with placebo in improving hair loss in patients undergoing treatment with GLP-1/GIP agonists. This 6-month, randomized, placebo-controlled clinical study investigates whether daily supplementation with Olistic© Next Women leads to significant improvements in hair loss in this patient population. In addition, the study assesses the safety and tolerability of the product throughout the treatment period.
