Brief Summary
A single-center, open-label clinical study to evaluate whether a dietary supplement can reduce hair loss in women with GLP-1-associated telogen effluvium. Participants will use the supplement for 120 days. Researchers will evaluate hair loss, hair density, and hair growth through clinical assessments, hair measurements (trichogram), and participant questionnaires.

Study Arms (1)
Dietary Supplement
EXPERIMENTALFemale participants with GLP-1-associated telogen effluvium will receive a dietary supplement once daily for 120 days. Efficacy will be evaluated through trichogram analysis, clinical assessments, and participant questionnaires, with safety monitored during the study.
Interventions
Dietary supplement containing vitamins, minerals, amino acids, and silicon intended to support hair health and reduce hair loss.

- Hair transplantation within the previous 18 months.
- Use of topical dermatological products for therapeutic or specific cosmetic purposes on the study area (scalp), such as hair tonics, topical minoxidil, medicated lotions, or acid-based treatments, within 48 hours prior to study initiation.
