Hair Loss on GLP-1 Medications

Starting a GLP-1 medication like Wegovy (semaglutide) or Zepbound (tirzepatide) can be an exciting step toward improving your health, energy, and confidence. For many patients, it marks the beginning of meaningful progress and feeling more like themselves again.

However, for some, one unexpected side effect can feel frustrating:

hair shedding.

The good news? In most cases, this is temporary, manageable, and often preventable with the right support.

At Flow Wellness, we take a proactive approach to protecting hair health during weight loss so you can feel your best every step of the way.

Why Does Hair Loss Happen on GLP-1 Medications?

First, it’s important to know: GLP-1 medications themselves do not directly cause hair loss.

Instead, what often leads to shedding is the rapid weight loss, reduced calorie intake, and nutrient depletion that can happen during treatment.

This is commonly known as telogen effluvium, a temporary form of hair shedding that occurs when the body experiences physical stress.

Common triggers include:

• rapid weight loss
• inadequate protein intake
• low iron or ferritin
• low zinc
• low biotin and B vitamins
• reduced calorie intake
• hormonal shifts
• physical stress on the body

In other words, when your body is working hard to adapt to weight loss, it naturally prioritizes essential functions first. As a result, hair growth can temporarily move to the “back burner.”

The reassuring part is that this is usually reversible.

Slow and Steady Weight Loss Matters

Just as importantly, losing weight too quickly can significantly increase the risk of hair shedding. While fast results may feel exciting, the body often does best with a more gradual approach.

In general, 1–2 pounds per week is the fastest rate at which most people should be losing weight. Anything faster can increase physical stress on the body and make nutrient depletion more likely, which in turn can contribute to hair loss, fatigue, and muscle loss.

At Flow Wellness, we focus on sustainable, healthy fat loss—not crash dieting. This means protecting not only your metabolism, but also your hair, muscle mass, and long-term results.

When Does Hair Shedding Usually Start?

Typically, hair shedding begins 8–12 weeks after starting GLP-1 treatment or after a period of faster weight loss.

Because of this delay, it can sometimes feel like the medication is the direct cause. However, in reality, it is usually the body responding to the earlier weight-loss phase.

Fortunately, for most patients, hair regrowth begins once nutrition stabilizes and weight loss becomes more gradual.

How to Protect Your Hair While on GLP-1s

The best strategy is prevention.

Rather than waiting for shedding to start, we recommend supporting hair health from the beginning.

1. Prioritize Protein Intake

First and foremost, hair is made primarily of protein.

If you are not eating enough, your body may redirect protein away from hair growth and toward essential functions.

A good general target for many patients is 80–120 grams of protein daily, depending on body size and goals.

Focus on foods such as:

• eggs
• Greek yogurt
• lean meats
• fish
• protein shakes
• collagen support
• legumes

Simply put, adequate protein is one of the most important ways to protect your hair during weight loss.

2. Replace Key Hair Nutrients

In addition, rapid weight loss can deplete nutrients essential for healthy hair growth.

That’s why we offer our Hair Support Vitamin Program — $149 for a 3-month supply.

This targeted vitamin blend helps replenish nutrients commonly depleted during GLP-1 therapy and supports stronger, healthier hair growth from within.

It’s one of the easiest and most effective ways to stay ahead of shedding while continuing your progress.

3. Support the Scalp Directly with Copper Peptides

For patients noticing early thinning (or who want to prevent hair thinning), one of our favorite options is a topical copper peptide scalp solution for about $60.

Your Flow Wellness provider can send you a link to purchase it through Fullscript, or you can pick it up in our Bend office.

Copper peptides help support:

• scalp circulation
• follicle health
• stronger hair anchoring
• healthier growth cycles
• improved hair density over time

This easy at-home topical solution pairs beautifully with nutritional support. In fact, for many patients, combining internal and topical support gives the best results.

4. Biotin Injections at Home — $149/Month

For those who want a more aggressive hair-support plan, we also offer take-home biotin injections for $149 per month.

Biotin helps support:

• hair strength
• nail growth
• skin health
• keratin production
• energy metabolism

These are easy to administer at home and can be a great addition during active weight loss phases.

5. Beauty IVs Available in Bend

Finally, for our Bend patients, we also offer Beauty IVs designed to support hair, skin, and hydration from the inside out.

These IVs include targeted nutrients and biotin that help replenish what rapid weight loss may deplete.

They’re an excellent option if you want an extra boost while staying on track with your GLP-1 goals.

The Bottom Line

Hair shedding during GLP-1 treatment is usually temporary and preventable.

The key is staying proactive with:

• adequate protein
• slow, sustainable weight loss
• targeted vitamins
• scalp support
• biotin injections
• IV nutrient therapy

At Flow Wellness, we help patients lose weight without sacrificing how they look and feel along the way. Because feeling confident includes keeping your hair healthy, too.
