The Biology of GLP-1 Hair Loss Happens
Significant caloric deficit triggers a stress-related shedding response where a larger-than-normal percentage of hair follicles concurrently enter the resting phase. Under normal conditions, only a small percentage of follicles are in telogen at any moment. During dramatic weight loss, this can rise to 20-40%.
Important nutrients that worsen GLP-1 hair loss include:
- Protein: Inadequate protein intake due to reduced appetite
- Iron: Iron stores decrease with lower eating
- Biotin: Required for follicular health
- Zinc: Necessary for cell division
- Cholecalciferol: Plays a role in anagen phase maintenance
