Hair loss is an increasingly reported concern among GLP-1 users. While not listed as a common side effect, many people notice increased shedding during treatment. Here's what the science says and what you can do about it.
Key Points About GLP-1 and Hair Loss
- • Hair loss is linked to rapid weight loss, not necessarily the medication itself
- • This type of hair loss is called telogen effluvium
- • It's usually temporary and reversible
- • Nutritional deficiencies during weight loss can contribute
Why Rapid Weight Loss Causes Hair Loss
When your body experiences significant stress—including rapid weight loss—it can shift hair follicles into the "resting" phase (telogen). About 2-3 months later, these hairs fall out. This is your body's way of conserving resources for essential functions.
How to Minimize Hair Loss
Prioritize Protein
Hair is made of protein. Aim for 60-100g daily, depending on your body weight. This is crucial when eating less overall. Focus on lean meats, fish, eggs, and legumes.
Take Key Supplements
Biotin, iron, zinc, and vitamin D all support hair health. A good multivitamin can help fill nutritional gaps when eating less. Check levels with your doctor.
Don't Lose Too Fast
Extremely rapid weight loss increases hair loss risk. A steady 1-2 pounds per week is healthier for your hair (and overall health) than 5+ pounds per week.
Be Gentle with Your Hair
Avoid tight hairstyles, excessive heat styling, and harsh chemical treatments during this time. Use a gentle shampoo and wide-tooth comb.
When to Expect Recovery
Telogen effluvium is self-limiting. Once your weight stabilizes and nutrition improves, hair typically regrows over 6-12 months. Most people see significant improvement once they reach their maintenance phase.
The Bottom Line
Hair loss during GLP-1 treatment is usually due to rapid weight loss and nutritional changes, not the medication itself. Prioritize protein, consider supplements, and be patient—hair typically regrows once weight stabilizes.
