They started a GLP-1 medication like Ozempic, Wegovy or Mounjaro, the weight started coming off, and then a few months later their hair started coming out in the shower, on the pillow and in the hairbrush. If that's you, you're not imagining it, and you're not alone. The good news is that this kind of hair loss is often very treatable. But the treatment that most people search for first, PRP, isn't always the best place to start. ## Why do GLP-1 medications cause hair loss? Researchers are still sorting out exactly how GLP-1 medications and hair loss are connected, but the pattern is becoming clearer. Larger studies have found higher rates of hair loss with semaglutide (Ozempic, Wegovy) and tirzepatide (Mounjaro, Zepbound), and women appear to be affected more often than men. The most likely explanation isn't the medication acting directly on your hair. It's what the medication does to the rest of your body: - Rapid weight loss is a stressor. Any big, fast change in the body can push a large number of hair follicles into their resting phase at the same time. A few months later, those hairs shed together. This is called telogen effluvium , and it's the same kind of shedding we see after surgery, illness, childbirth or crash dieting. - You're eating a lot less. GLP-1s are very good at reducing appetite. That's the point. But it also means many people aren't getting enough protein, iron, zinc, vitamin D and B vitamins to keep up with what growing hair needs. - Hair is low on the body's priority list. When resources are tight, your body sends them to your heart, brain and muscles first. Hair follicles are one of the first places to go without. For women in midlife, there's often one more layer. Shifting hormones in perimenopause and menopause can already be thinning hair, and a GLP-1 can make an existing pattern of thinning more noticeable. ## So why not just do PRP? [PRP (platelet-rich plasma)](https://www.biorevive.ca/hair-restoration) is a great treatment, and at BioRevive it's performed by our registered nurse in the right situations. But for GLP-1 related shedding, it's often not the best first step. Here's why. 1. PRP has the strongest evidence for a different kind of hair loss. Most of the research on PRP is for pattern hair loss (androgenetic alopecia), where follicles are gradually shrinking over time. Telogen effluvium is different. The follicles are usually still healthy, they've just been pushed into a resting phase all at once. The evidence for PRP in this kind of shedding is much more limited. 2. PRP is made from your own blood. Your platelets and growth factors are concentrated and placed back into your scalp. That's what makes it so powerful. But if your body is currently low on protein, iron or other key nutrients, we'd rather rebuild that foundation first so your follicles have what they need to respond. 3. If the trigger is still there, the shedding often continues. If you're still losing weight quickly and still under-eating, the stress on your follicles hasn't gone away. Treating the scalp without addressing what's driving the shedding can mean spending money on treatments while the cause keeps going. None of this means PRP is off the table. For some women, especially those whose GLP-1 has revealed or sped up pattern thinning, PRP can be a very good option later in the plan. It just usually isn't where we start. ## What we look at first For the most complete picture, we start with a [naturopathic consultation](https://www.biorevive.ca/naturopathic-medicine). For someone on a GLP-1, we're especially interested in: - Ferritin (iron stores). Low ferritin is one of the most common contributors to hair shedding in women, and it often drops further with reduced food intake. - Protein intake. Hair is made of protein. Many people on GLP-1s are eating far less than they realize. - Vitamin D, zinc and B12. All play a role in the hair growth cycle and can become depleted with lower intake. - Thyroid function. Thyroid shifts can affect hair, and they're worth checking whenever hair changes. - Hormones. In midlife, estrogen, progesterone and androgen balance can all influence how your hair grows. We also do a [HairMetrix™ hair assessment](https://www.biorevive.ca/hairmetrix), which counts your follicles, measures your hair and tracks how many hairs grow from each follicle. That gives us an objective baseline so we can see whether things are improving. ## What often works better first Once we know what's going on, a plan for GLP-1 related shedding often includes: - Rebuilding your nutrient status with targeted supplementation based on your labs, and practical support to hit your protein goals while your appetite is low. - Microneedling with mesotherapy , which delivers vitamins, amino acids and peptides directly to the scalp to support follicles while the rest of your body catches up. We explain more in [our post on microneedling with mesotherapy for hair](https://www.biorevive.ca/blog/microneedling-mesotherapy-hair-loss-calgary). - [Keravive scalp treatments](https://www.biorevive.ca/keravive) to cleanse, hydrate and nourish the scalp so new growth has a healthy environment to come through. - Working with your prescriber if the pace of weight loss or dose needs a conversation. Then, if there's an underlying pattern of thinning that needs more support, we can layer in regenerative options like PRP or exosomes. ## Will my hair grow back? In many cases of telogen effluvium, yes. Shedding usually settles once the trigger is addressed, and regrowth follows over the next several months. Hair grows slowly, so patience matters, but addressing the cause early can make a real difference in how quickly you recover. ## Hair loss and GLP-1 FAQ Does Ozempic cause hair loss? Hair loss has been reported with GLP-1 medications, especially semaglutide and tirzepatide. It's most often linked to rapid weight loss and reduced nutrient intake rather than a direct effect of the drug on hair. Should I stop my GLP-1 medication? Not on your own. Talk to your prescriber. In many cases, the hair loss can be addressed while you continue your medication. Is PRP bad after a GLP-1? No. It's just often not the best first step. We usually address nutrient status and the shedding trigger first, then consider PRP if pattern thinning is part of the picture. How long until I see regrowth? Shedding often settles within a few months of addressing the cause, and visible regrowth typically follows over several more months. ## Book a hair and scalp consultation in South Calgary If you've noticed more shedding since starting a GLP-1, the best first step is finding out why.
