If a client is on a GLP-1 medication and you’re noticing changes in their hair, you’re not imagining it. Rapid or significant weight loss, a common effect of GLP-1 medications, can disrupt the hair growth cycle and contribute to increased shedding and hair thinning. The good news: there are proactive steps you can recommend to support your clients’ hair health throughout their weight-loss journey.

GLP-1 Weight Loss Can Impact Root Causes of Hair Thinning

During times of rapid weight loss, the body can experience stress that causes it to deprioritize non-essential functions. Hair growth, while important, ranks lower than vital organ function, so resources can be diverted away from the hair. This can result in increased shedding and hair thinning, typically appearing a few months after rapid weight loss begins and may be more pronounced in women and older adults.1

Hair follicles are among the most metabolically active structures in the body, depending on a steady supply of protein, vitamins, and minerals. Because GLP-1 medications reduce appetite significantly, some users may not be consuming enough of these key nutrients to support healthy hair growth while taking them.

How to Support Hair Health During GLP-1 Weight Loss

1. Prioritize protein. GLP-1 medications reduce appetite, which makes it easy to undereat protein, one of the most essential nutrients for the hair growth cycle. Even as caloric intake decreases, it’s important to meet daily protein needs. 

2. Monitor for nutrient gaps. Rapid weight loss can create nutritional gaps that affect hair health over time. Clients should focus on nutrient-dense foods and check for any deficiencies through bloodwork, particularly iron, zinc, vitamin D, and B vitamins.

3. Support hair from within. GLP-1 weight loss doesn’t have to mean hair thinning. Nutrafol Hair Growth Nutraceuticals are clinically tested to improve hair growth—and rigorous safety reviews support that they can be used with GLP-1 medications.*

4. Get ahead of thinning before it starts. Don’t wait until shedding becomes noticeable to take action. Supporting hair health proactively—at the start of a GLP-1 journey, or even before—helps set the hair growth cycle up for success as the body changes.

If your client has concerns, or medical condition(s), or are taking prescription medication(s), they should speak to a healthcare provider before adding Nutrafol products to their routine. We do not recommend taking Nutrafol supplements if pregnant. Breastfeeding individuals should only consider our breastfeeding-friendly Postpartum formula.
