Good question — the link between GLP-1 receptor agonists (GLP-1 RAs) (like semaglutide, liraglutide, or tirzepatide) and hair loss has been increasingly discussed
as more people use these drugs for weight loss or diabetes.
The most likely reason for hair shedding in people on GLP-1 drugs is telogen effluvium —
a temporary hair shedding that occurs when the body undergoes physiologic stress or nutrient shifts.
When calorie intake drops, or food choices narrow, you can become
deficient in nutrients important for hair growth:
Protein (keratin synthesis)
Iron
Zinc
Biotin
Vitamin D
B vitamins
Even if blood levels aren’t dramatically low, mild deficiency can contribute to shedding.
Weight loss (especially fat loss) can alter:
Thyroid hormone levels
Sex hormone binding globulin (SHBG)
Estrogen/testosterone balance
These hormonal changes can influence hair growth cycles,
sometimes contributing to temporary shedding.
