Biotin is one of the most commonly recommended supplements for hair health, but its actual effectiveness for GLP-1-related hair loss is limited — and here's why understanding the cause matters.
The real cause of hair loss on GLP-1 medications:
The hair loss most people experience is telogen effluvium — a temporary shedding triggered by rapid weight loss, caloric restriction, and nutritional stress. It's not caused by a biotin deficiency in most cases. When your body is under metabolic stress from significant calorie reduction, it shifts hair follicles from the growth phase into the resting phase, and 2 to 4 months later those hairs fall out.

The timeline:
**Talk to your provider** if shedding is significant — they can check ferritin, thyroid, zinc, and vitamin D to rule out treatable deficiencies beyond the weight-loss trigger.
