Does GLP-1 (Ozempic) cause hair loss?

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.


Hair Loss Often Comes from Rapid Weight Loss


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.

  • Rapid weight loss = metabolic stress → more hairs shift prematurely from the “growth” phase (anagen) to the “resting/shedding” phase (telogen).
  • This typically starts 2–3 months after the onset of rapid weight loss.
     

Nutrient Deficiencies Can Contribute

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.


Hormonal and Metabolic Adjustments

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.
