The GLP-1 Effect: What It Could Mean for the Professional Hair Industry
What’s trending, what’s changing, and how your Salon Distributorship can be prepared.
Ozempic. Wegovy. Mounjaro. Zepbound.
A few years ago, most consumers had never heard these names. Today, GLP-1 medications have become part of everyday conversation—and their impact is beginning to reach beyond weight management and into the professional beauty industry.
According to the Gallup National Health and Well-Being Index, 11% of U.S. adults reported currently using GLP-1 medications specifically for weight loss in 2026, compared with 3% in 2024. Another 15% reported having used them for weight loss at some point.
That represents millions of consumers experiencing significant physical changes—and increasingly, some are asking questions about changes they notice in their skin and hair.
For The Prell Group and BBCOS, this is a conversation worth watching.
Because when consumers begin asking new questions, salons need answers. And when salons need answers, distributors have an opportunity to make sure their customers are prepared.
First: What Exactly Are GLP-1s?
GLP-1 stands for glucagon-like peptide-1, a naturally occurring hormone involved in blood-sugar regulation, appetite and digestion.
Medications that act on this pathway—including semaglutide and tirzepatide—are prescribed for conditions including diabetes and obesity and can produce substantial weight loss.
But significant or rapid changes in body weight can sometimes have effects consumers don't expect.
One of the conversations receiving increasing attention is hair shedding.
The American Academy of Dermatology explains that some patients taking GLP-1 medications experience thinning hair. Dermatologists believe that, in many cases, this may be associated with rapid weight loss and the physiological stress it places on the body, which can trigger a temporary shedding condition known as telogen effluvium.
Reduced food intake may also mean that some people consume less protein, vitamins and other nutrients important to normal hair growth. Researchers are still investigating whether GLP-1 medications themselves may have a direct effect on hair growth.
This distinction matters.
Hair shedding associated with weight loss does not necessarily mean that a medication is directly damaging the hair follicle. The cause can be multifactorial, and clients experiencing significant or persistent hair loss should be encouraged to speak with a qualified medical professional.

The takeaway isn't simply that scalp care is growing.
It's that professional beauty is beginning to treat the scalp as a category of its own.
The numbers are worth watching.
In clinical trials of Wegovy 2.4 mg, hair loss was reported by 3.3% of treated patients compared with 1% receiving placebo. At the 7.2 mg dose, hair loss was reported by 5.8% of treated patients compared with 1% receiving placebo.
Hair loss has also been reported in clinical studies of Zepbound. In those studies, hair loss was reported in 7.1% of female patients and 0.5% of male patients, compared with 1.3% and 0% respectively in the placebo groups. The prescribing information specifically notes an association with weight reduction.

So What Does This Have to Do With Professional Hair Care?
Quite a lot.
A salon professional cannot diagnose nutritional deficiencies, diagnose or treat telogen effluvium, or replace the role of a physician or dermatologist.
But that doesn't mean the professional beauty industry has no role to play.
A client experiencing increased shedding or changes in the appearance and quality of their hair may become more conscious of their scalp condition, hair strength, density, breakage and daily hair-care routine.
That changes the conversation behind the chair.
Instead of simply asking:
“What shampoo should I use?”
A client may increasingly be asking:
“What can I do to take better care of my scalp and the hair I still have?”
That is a conversation the professional beauty industry should be prepared to have.
The Opportunity Starts at the Root
At The Prell Group and BBCOS, we've been focused on a broader shift in professional hair care: modern hair care starts at the scalp—not just with the hair we can see.
As GLP-1 use continues to grow, salons may encounter more clients concerned about s
hedding, reduced density, fragile hair or changes in the overall appearance of their hair.
That creates an opportunity—but also an important responsibility.
Stylists should never promise to treat a medical condition or replace the advice of a physician, dermatologist or nutrition professional.
What salons can do is help clients take better cosmetic care of their scalp and hair during a period when both may deserve greater attention.
And that is where professional products and education become important.
Thera Tech: Starting Where Hair Starts
For this conversation, BBCOS Emphasis Thera Tech offers a particularly relevant approach.
Thera Tech is an advanced dermocosmetic system built around the principle that hair well-being starts with the scalp. The line is designed to support hair growth, rebalance the scalp and support stronger, denser and healthier-looking hair. One product in particular stands out: Growth Boost Serum.
The serum combines PROCAPIL® and CAPIXYL™ and is formulated to support hair anchoring, follicular activity and hair vitality. PROCAPIL® combines Biotinyl-GHK, apigenin and oleanolic acid, while CAPIXYL™ incorporates a biomimetic peptide and selected plant extract designed to support follicle structure, anchoring and scalp balance.
Importantly, this does not mean treating GLP-1-related hair loss. It means giving salons a sophisticated professional cosmetic option for a concern their clients may increasingly bring through the door:
“My hair feels thinner and weaker. What can I do to take better care of it?”
And Then There's the Hair You Already Have
Scalp and follicle care are only part of the conversation.
When someone feels that their hair is becoming thinner or more fragile, protecting the quality and integrity of the existing hair fiber becomes equally important. This is where another BBCOS technology becomes relevant: Emphasis 4'Repair.
Designed for weak, stressed or damaged hair, 4'Repair is an ultra-fast leave-on treatment developed to strengthen the hair fiber and improve resistance, elasticity and density in just four minutes. Its formula combines fermented Rice Water, Luminescine, Pisum Sativum Peptide and PhytoChest.
According to BBCOS technical documentation, laboratory testing of Pisum Sativum Peptide showed an increase in hair diameter of up to 14%, while PhytoChest was reported to help
prevent moisture loss by up to 30%.
The distinction between the two systems is important: Thera Tech focuses the conversation on the scalp, follicle and overall hair vitality. 4'Repair focuses on protecting and strengthening the hair fiber that is already there.
Together, they give salon professionals two complementary cosmetic approaches to an emerging concern—without crossing the line into medical treatment.
What Does This Mean for Distributors?
This is where the trend becomes a business conversation.
Millions of Americans are now using GLP-1 medications for weight management. Hair shedding and thinning are already being discussed by dermatologists, patients, the media and consumers themselves.
And the salon chair is a natural place for those beauty and wellness conversations to continue.
For distributors, the opportunity isn't to create fear around GLP-1 medications or promise a solution to a medical problem.
The opportunity is to prepare your salons for the questions their clients may already be asking.
Do your customers understand the difference between shedding and breakage?
Do they know when a client should be referred to a medical professional?
And when the concern is cosmetic, do they have professional products capable of addressing scalp care, hair vitality, strength and fiber integrity?
These questions create opportunities for education, professional treatments, home-care recommendations and stronger relationships between distributors, salons and their clients.
Most importantly, they allow the professional salon to remain relevant as the conversation around beauty increasingly overlaps with wellness.
Is Your Territory Ready for the Conversation?
At The Prell Group, our goal with Beauty Executive Summaries isn't simply to tell you what's trending.
We want to understand what those trends could mean for your business.
GLP-1 medications belong in the medical world. But when changes associated with weight loss begin showing up in the mirror, they can become part of the beauty conversation too.
BBCOS has already invested in professional technologies centered around scalp wellness, hair vitality and fiber strength. For distributors, that means professional tools are already available to help salons address the cosmetic side of this emerging conversation responsibly.
The question is whether the opportunity exists in your territory.
Are your salons already hearing these concerns?
Are their clients asking about thinning, shedding or weakened hair?
And are you giving your salons the products and knowledge they need to respond?
If you'd like to explore whether this trend could become relevant to your business, let's talk.
The Prell Group can help evaluate the opportunity within your market, identify the BBCOS products that best fit your salon network and, where appropriate, arrange a professional evaluation box so you and your customers can experience the systems firsthand.
Because sometimes the biggest shifts in beauty don't start with a new look.
They start with a new question in the salon chair.
And right now, that question may simply be:
“What can I do about my hair?”
