SEE HOW IT WORKS

Research cited by

You finally found something that worked for your body.

Now it feels like your hair is paying for it.

You noticed it in the shower first. A few extra strands circling the drain.

Then a few more. Then enough to make you stop mid-rinse and stare.

Your brush started filling up faster. Your ponytail felt thinner.

Your part line started showing scalp you'd never seen before.

You looked in the mirror. Something felt off. The woman staring back wasn't quite you.

Maybe you're still on your medication. Maybe you've already stopped.

Either way, the shedding keeps going.

Some women stop their medication because of it. Others keep going and just... watch.

Because GLP-1 hair loss doesn't always happen in real time.

For many women, it shows up during the rapid weight-loss phase — or in the months after — right when you think the hardest part should be over.

You went to your doctor. She didn't have an answer. Because there isn't one.

→ The biotin on Amazon? Designed for nutritional deficiency. Not this.

→ The $79 hair vitamin from Instagram? Designed for genetic thinning. Not this.

→ Minoxidil? Designed for pattern baldness. You use it forever. Not this.

GLP-1 shedding is a different biological event.

And until now, nothing was formulated for it.

You shouldn't have to choose between the progress you fought for and the hair that makes you feel like yourself.

Here's what's actually happening inside your follicles:

It's Not One Problem. It's Three.

1 Metabolic Shock 2 Telogen Shift 3 Nutrient Depletion Your follicles need support from outside

1. Metabolic Shock

Rapid weight loss sends a stress signal to your hair follicles. Your body prioritizes vital organs over hair.

Follicles shut down and enter a resting phase. All at once.

2. Telogen Shift

During rapid weight loss, up to 50% of follicles can shift to resting phase at once.

2-4 months later, they all release. That's why shedding can start on your medication, or continue months after you've stopped.

3. Nutrient Depletion

Your appetite is suppressed. You're eating less. The nutrients your follicles need to restart their growth cycle aren't arriving.

The follicles that want to wake up can't.

Biotin goes through your gut and hopes to reach your follicles.

Hair vitamins were built for genetic thinning. Minoxidil was built for pattern baldness.

None of them address what's actually happening during GLP-1 shedding.

That's why your doctor said "just wait." Not because waiting is the answer. Because she had nothing else to offer.

So our lab built a topical protocol that goes directly to the scalp. Not through the gut. Not through the bloodstream. Where the damage is actually happening. During the shedding window that can begin on your medication and continue after.

Research shows the heaviest shedding occurs between months 3-9 of rapid weight loss.

In clinical trials, 3-7% of women on GLP-1 medications reported hair loss. Real-world estimates suggest it may be as high as 25-33%.

If you're in this window, the time to act is now.

Dr. Sarah Mitchell
"One of the most distressing things patients tell me when they're a few months into GLP-1 treatment isn't about nausea or fatigue. It's: 'I'm losing my hair.' The good news is telogen effluvium is temporary. But the bad news is 'temporary' can mean 6-12 months of visible shedding. Supporting the follicle environment during that window — topically, directly — is one of the most practical steps a woman can take."

A Different Approach. Directly to the Scalp.

Not another oral supplement. Not a repurposed hair vitamin. A topical peptide protocol designed for women experiencing GLP-1-related shedding. During treatment and in the months after. Applied where the problem actually lives.

You fought for this progress. Your hair shouldn't be the price.

Reduces Daily Shedding at the Follicle Level

Less hair in the brush after using PD-5 Complex™

The first thing you'll notice: less hair in your brush. Less in the shower drain. Less on your pillow.

Saw Palmetto, one of seven active ingredients in the PD-5 Complex™, has been studied in multiple randomized controlled trials:

  • A 2023 clinical study (n=80, published in CCID) found topical Saw Palmetto reduced hair shedding by 22% in 16 weeks
  • The same study showed a 7.6% increase in hair density (p<0.001)
  • Topical application works locally. No effect on your hormones, no systemic side effects

Shedding Reduction After 16 Weeks

Placebo
−3%
Saw Palmetto
−22%

Sudeep et al. (2023), n=80, p<0.05. Published in CCID.

The shedding doesn't stop overnight.

But within 4-6 weeks, most women notice the brush isn't as full as it was.

"I was counting hairs. I know that sounds crazy but I was literally counting them. After about five weeks, I stopped counting. Not because I forced myself to. Because there wasn't enough to count anymore."

— Rachel M., 38

Supports Your Hair's Natural Growth Cycle

Baby hairs appearing at the temples

Reducing shedding is step one. Step two is helping dormant follicles re-enter the growth phase.

Rosemary Extract, another key ingredient in the PD-5 Complex™, has been compared head-to-head against minoxidil:

  • In a 2015 RCT (n=100, published in SKINmed), rosemary oil performed comparably to minoxidil 2% at 6 months
  • Both groups showed significant hair count improvement vs baseline
  • Rosemary caused less scalp irritation than minoxidil
  • A 2025 study (n=90, published in Cureus) found rosemary-based formulas increased growth rate by 57.7% and thickness by 68.7% in 90 days

Unlike minoxidil, you don't have to use this forever.

This supports your follicles during the shedding window. Not for the rest of your life.

"My hairstylist was the first one to say something. She picked up my hair and said 'I see baby hairs.' That was month three. I almost cried in the chair."

— Jennifer K., 44

5 Bioactive Peptides That Signal Your Follicles

PD-5 Complex™ peptide serum applied to scalp

This is what makes the PD-5 Complex™ different from anything else on the market.

Five bioactive peptides. Each one a tiny protein that sends a specific signal to your hair follicles:

  • Supports blood flow to the scalp by mimicking VEGF, the protein your body uses to build new blood vessels around follicles
  • Signals the growth phase by mimicking bFGF, encouraging dormant follicles to reactivate
  • Supports follicle cell activity by mimicking IGF-1, a growth factor involved in hair cycling
  • Supports the scalp environment and helps create conditions for healthy follicle function
  • Supports follicle signaling and helps maintain communication between follicle cells

In a 2019 randomized, double-blind trial (n=60), biomimetic peptides showed 68% hair growth improvement at 4 months vs 28% for placebo (p<0.001).

Published in the Journal of Dermatological Treatment.

Think of peptides as text messages to your follicles:
"Stay in growth phase. Don't shut down. Keep going."

"I'd tried everything oral. Biotin, Nutrafol, collagen, even prescription vitamins. Nothing worked because nothing was getting to my actual scalp. This is the first thing I've used that goes directly where the problem is."

— Amanda L., 41

Fuller-Looking Hair You Can Actually See

Visibly fuller hair after 90 days

This is the part most women don't expect: the moment you stop checking.

You stop counting strands in the brush. You stop studying your part line.

You stop bracing yourself every time you shower.

You just... move on with your day.

The PD-5 Complex™ combines ingredients studied in clinical trials with over 500 participants. Not in a lab. In real women. With real hair loss.

The results they report:

  • Fewer strands in the brush
  • Less scalp visible at the part line
  • A ponytail that starts feeling like a ponytail again

You're not waiting for a miracle. You're supporting the one thing you can actually influence. So you can get back to feeling like yourself again.

Signs Your Shedding May Be Accelerating

These are the signs most women miss. Or explain away:

If you're recognizing three or more of these signs, your shedding is likely accelerating.

The follicles shifting into their resting phase now will release hair 2-4 months from today.

Every week without follicle support means more follicles entering their resting phase. The ones shifting today will release hair 2-4 months from now. The window to support them is before the shedding peaks, not after.

Why Your Doctor Can Only Say "Wait"

GLP-1 medications have only been widely prescribed since 2021.

The hair loss side effect is documented in FDA labels, but the research on why it happens is still emerging. The medical system hasn't caught up.

Your experience is real. It's documented. And you're not imagining it.

Dermatologists understand the mechanism (telogen effluvium). But they have no targeted tool for it.

The standard advice (biotin, patience, maybe minoxidil) wasn't designed for this type of shedding.

That gap is exactly what the PD-5 Complex™ was built to address.

A topical protocol that supports the follicle environment directly, during the specific window when rapid weight loss is pushing follicles into their resting phase.

Your 90-Day Hair Support Timeline

Week 1-4

The PD-5 Complex™ begins working at the follicle level. Peptides signal dormant follicles. Saw Palmetto supports the local environment. Most women notice reduced shedding. Less hair in the brush, less in the shower. Your scalp starts feeling supported.

Month 2-3

Baby hairs. The first visible sign. Tiny new growth at the temples and along the part line. The shedding has slowed significantly. Your ponytail stops getting thinner.

Day 90+

Visible density improvement. Fuller-looking hair that you can see in photos and in the mirror. The part line narrows. The confidence shifts. Not overnight. But unmistakably.

Provant Labs PD-5 Complex™ Serum

Real Results. Real Women.

Individual results may vary. Photos taken at Day 1 and Day 90 of consistent daily use.

None of These Were Designed for GLP-1 Hair Loss

  The Problem Provant PD-5 Complex™
Biotin ($10-25/mo) Goes through gut, useless unless deficient Delivers peptides directly to scalp
Nutrafol ($79-88/mo) Oral. Designed for genetic thinning, not GLP-1 shedding Topical peptide protocol. Supports follicles during GLP-1 shedding window
Collagen ($20-40/mo) Marginal at best, no evidence for TE Contains Saw Palmetto shown to reduce shedding by 22%
Rosemary oil ($5-15) Right idea, wrong concentration, no supporting ingredients Clinical-grade rosemary + 5 bioactive peptides + Saw Palmetto
Minoxidil ($15-40/mo) Works, but designed for genetic hair loss. Must use forever OTC, no prescription, no forever commitment
"Just wait it out" The only answer doctors have. Because nothing else existed Now there's a protocol. Supports follicles during the critical 3-9 month window

What's Inside the PD-5 Complex™

5 Bioactive Peptides

sh-Polypeptide-1, sh-Polypeptide-9, sh-Polypeptide-11, sh-Oligopeptide-2, sh-Oligopeptide-10. Each one sends a targeted signal to your hair follicles. Supporting blood flow, growth phase activation, and follicle cell activity.

Saw Palmetto (Serenoa repens)

Shown to reduce hair shedding by 22% and increase density by 7.6% in a 2023 randomized controlled trial. Works locally at the scalp. No systemic effects.

Rosemary Extract (Rosmarinus officinalis)

Comparable to minoxidil 2% in a published RCT. Supports the hair growth phase without the side effects or lifetime commitment of minoxidil.

Supporting Ingredients

Arginine: supports blood circulation to scalp via nitric oxide production. Scutellaria Baicalensis: anti-inflammatory, supports Wnt/β-catenin pathway.

Vegan. Hormone-free. Cruelty-free. Fragrance-free. Paraben-free. Silicone-free. Sulfate-free.

Who Is Provant Labs?

When our lead chemist watched three women in her clinical trial stop their GLP-1 medication because of hair loss, she knew oral supplements weren't the answer.

Why Dermatologists Are Paying Attention

Dr. Laura Chen
"For years, the only advice we could give women experiencing GLP-1 hair loss was to wait. But telogen effluvium has a window — and supporting the follicle environment during that window makes physiological sense. A topical approach that delivers peptides and DHT-blocking botanicals directly to the scalp addresses the problem where it's actually happening. I'm recommending this to my patients and watching the results closely."

Frequently Asked Questions

"Is this safe to use with my medication?"

Yes. The PD-5 Complex™ is a topical cosmetic serum applied to your scalp. It does not interact with GLP-1 medications, oral supplements, or any prescription drugs.

Always consult your healthcare provider if you have specific concerns.

"How long until I see results?"

Most women notice reduced shedding within 4-6 weeks. Visible new growth typically appears at month 2-3. Consistent use for 90 days is recommended for best results.

"Is weight-loss-related hair loss permanent?"

No. Telogen effluvium from rapid weight loss is temporary and reversible in the vast majority of cases. Supporting your follicles during the shedding window may help reduce the severity and duration.

"How is this different from Nutrafol or Viviscal?"

Those are oral supplements designed for genetic hair thinning. A completely different condition.

GLP-1 hair loss (telogen effluvium) is a different biological event with a different mechanism. The PD-5 Complex™ is the first topical serum formulated specifically for GLP-1 hair loss. Applied directly to your scalp, not through your gut.

Different problem, different delivery, different protocol.

"Do I have to use this forever?"

No. This is designed to support your hair during the shedding window. Whether you're still on your GLP-1 medication, tapering, or have already stopped.

Most shedding occurs during months 3-12 of rapid weight loss. Once your weight stabilizes and your hair recovers, you can discontinue.

"What if it doesn't work for me?"

We offer a 90-Day Consistency Guarantee. Use it daily for 90 days. If you don't notice a difference, contact us for a full refund. No questions.
