Short answerHair shedding during GLP-1 weight loss is usually telogen effluvium, a temporary shift of hair into the resting phase triggered by rapid weight loss, low protein and nutrient gaps. It typically starts 2 – 4 months into weight loss and is reversible. Protein, nutrient correction and early regrowth therapy help.
Is the medicine damaging my hair?
Usually not directly. Rapid weight loss is a stress on the body, and the body responds by pushing more hairs into the resting (telogen) phase. Those hairs fall 2 – 4 months later. Low calorie intake, inadequate protein, and low iron, zinc, vitamin D or B12 make it worse.
How to reduce the risk
- Eat enough protein, often 1.2 – 1.6 g per kg of body weight a day as advised by your doctor
- Check and correct ferritin, vitamin D, B12, zinc and thyroid levels
- Avoid very rapid dose escalation, since slower weight loss sheds less
- Strength-train to keep muscle and metabolic health
Treating it
Telogen effluvium usually recovers within 6 – 9 months once the trigger settles. If it reveals underlying pattern hair loss, or you want faster recovery, peptide regrowth therapy helps. Because I treat both weight and hair, I build hair protection into every GLP-1 programme.
