GLP-1 Medications & Hair Loss: What You Need to Know

The Rise of GLP-1 Medications

GLP-1 medications are becoming more common, especially for people looking to balance blood sugar and lose weight quickly. While the results can feel encouraging, many people are also noticing unexpected hair shedding that starts weeks or months after beginning these injections.

As a Certified Functional Trichologist, I don’t prescribe or discourage medications. My role is to help you understand what is happening inside your body, how it may be affecting your hair, and what you can do to support your system along the way.

Why Do GLP-1 Medications Trigger Hair Loss?

The medication itself is not usually the direct cause of shedding. What impacts your hair most are the changes happening in your body.

• Nutrient depletion: With a lower appetite, food intake often decreases, and that can mean fewer vitamins, minerals, and protein reaching your hair.
• Blood sugar shifts: Rapid changes in glucose levels create internal stress that can show up at the scalp.
• Rapid weight loss: When your body is changing too quickly, it can shift into “survival mode,” conserving energy for basic functions instead of hair growth.
• Stress response: Any type of stress, even from positive changes, can trigger a shedding cycle known as Telogen Effluvium (TE).

What You Can Do to Support Your Hair

If you are on a GLP-1 medication and noticing shedding, here are some simple but powerful ways to protect your hair health:

1. Prioritize protein. Hair is made of protein, so your body needs enough every day to keep follicles strong.
2. Balance your nutrients. Vitamins and minerals like iron, zinc, B-vitamins, and magnesium are key for growth.
3. Stay hydrated. These medications can sometimes affect digestion and hydration. Drinking water and mineral-rich fluids helps carry nutrients to your follicles.
4. Support your liver and gut. They are central to how your body processes both food and medication. If they are sluggish, your scalp will often show it.
5. Manage stress. Rest, light movement, and stress-management practices help keep cortisol in check, which reduces the shock on your hair cycle.

How Functional Trichology Helps

When I work with clients, I look beyond the surface. Together we review nutrition, lifestyle habits, and sometimes bloodwork to see what your body needs most. The goal is not to fight against the medication but to bring your body into balance so your hair has the best chance to thrive.

The Bottom Line

GLP-1 medications can help with blood sugar management and weight changes, but your hair health depends on how your body adapts. With the right support, you can protect your hair while also reaching your health goals.
