TLDR The hCG diet and testosterone therapy can cause hair loss in some people.
The document reported a case of new-onset androgenic alopecia in a man following a human chorionic gonadotropic (hCG) diet and testosterone pellet implantation. The patient, with a family history of mild androgenic alopecia, experienced sudden hair loss after starting the hCG diet and testosterone therapy. The hCG diet, often used for rapid weight loss, combined with testosterone pellets, which are used to treat male hypogonadism and increase muscle mass, can lead to increased androgen levels, potentially causing hair loss in genetically susceptible individuals. The study highlighted the need for awareness of this cosmetic side effect among potential users of these treatments.
