It’s not just restaurant portions—and the people eating them—that seem to be shrinking, thanks to the rapid rise of GLP-1 drugs, now taken by 11% of US adults, or about 29 million people. Hair volume and density appear to be following the same trend. According to social media analyst Spate, interest in GLP-1-related hair thinning is growing, with 302,000 related Google searches in the past 12 months—a nearly 58% increase year over year. Searches for “Does Wegovy cause hair loss?”, referring to the GLP-1 drug, are up 450% over the same period. And searches for “Mounjaro hair loss” have more than doubled year over year, according to Google data provided by Boots.

That interest is turning into spending. Online retailer Cult Beauty has seen sales in its hair loss and thinning category rise 30% in the past year, while Boots has recorded a similar 30% increase in scalp care.

The numbers don’t lie. What was once a niche part of the hair care market is now a major player in our beauty routines—and a significant growth opportunity for brands that can deliver.

Hair loss has a new consumer

Of course, it’s not just about GLP-1s. Hair loss is shifting from what McKinsey partner Sara Hudson calls a “relatively narrow, male-centered and medically managed concern” into a mainstream beauty, health, and wellness category. A much broader range of consumers are now seeking solutions for different types and causes of thinning—from perimenopause and female pattern hair loss to temporary shedding linked to GLP-1s or Covid.

In the consultancy’s global survey of 15,000 consumers across 13 countries, preventing or treating hair loss is now the third most common goal when shopping for hair care, behind only overall hair nourishment and hair control and styling. About one in five consumers globally regularly uses a product specifically to prevent or reduce hair loss.

Perhaps most interestingly, women are now more likely than men to use a hair loss product—22% versus 16%. This is a significant reversal for a category historically dominated by male-pattern baldness, and it greatly expands the number of consumers brands can reach.

“In the past five years, there’s been an influx of different people noticing hair thinning or loss of density,” says trichologist Hannah Gaboardi. She has also seen the demographic shift as more young women experience thinning and shedding.

Stress and genetics are among the potential triggers, along with hormonal changes, nutritional deficiencies, rapid weight loss, pregnancy, and menopause. “This is being driven by a growing understanding of specific life stage triggers: menopause, postpartum, and GLP-1 use,” says Alice Crossley, principal foresight analyst at The Future Laboratory.

Social media is a major driver, bringing female hair loss out of private conversations and into TikTok videos and Reddit threads. It has not only made the topic less taboo but also given consumers a new vocabulary around scalp health, shedding, and treatment—and what seems like an endless stream of possible solutions.

The GLP-1 effect

GLP-1s have added fuel to an already burning fire. While hair shedding linked to rapid weight loss is usually temporary, the sheer scale of GLP-1 use means a new group of consumers is looking for ways to protect or restore density.

Retailers have responded quickly. Earlier this summer, Boots introduced dedicated GLP-1 sections in more than 220 stores, curating products for some of the concerns that can come with significant weight loss, from skin elasticity and nutrition to hair loss. “In totality, weight loss treatment is creating an entirely new beauty need,” says Chelsey Saunders, director of hair care, skin care, and fragrance at Boots. “As demand grows, we expect customers to seek products that support visible changes in skin, body, and hair.”For haircare brands, though, GLP-1 users are just one part of a much larger opportunity.

The skinification of hair loss

If the past decade of beauty was about teaching consumers to understand skincare ingredients and focus on prevention rather than cure, that same mindset is now being applied to our scalps.

“Consumers increasingly treat the scalp like skin and hair thinning as a solvable health and wellness issue, rather than just a cosmetic concern,” says Hudson. This shift has come with a wave of products that would fit right into a skincare routine: targeted serums, exfoliating treatments, supplements, and red-light devices, all marketed with the language of actives, clinical studies, and efficacy.

At Cult Beauty, scalp treatment sales are up 147% year-on-year, and the recently launched K18 FutureIQ Biomimetic Hair Longevity Serum has already beaten the retailer’s launch targets. Boots, meanwhile, points to Plantur, Vichy, and Nizoral as the brands currently driving its scalp category. On the high street, L’Oréal, Dove, and Pantene have all recently launched anti-hair loss and growth-boosting formulas, while one bottle of Chāmpo’s viral Pitta Growth Serum sells every 30 seconds.

At the other end of the market, Currentbody’s LED Hair Growth Helmet is one of its bestselling red-light devices. E-commerce analytics platform Particl estimates that the innovative helmet generated around $539,000 from 627 units sold in the US in the last month alone. And just last week, Beyoncé’s scalp and haircare label Cécred announced it will launch in SpaceNK after a period of impressive growth. Its Ulta launch was the largest premium haircare rollout in the retailer’s history, and its Restoring Hair and Edge Drops — a density serum — is Ulta’s top seller in prestige haircare.

The timing is ideal. “Beauty as a whole has become saturated, skincare especially is crowded and hard to innovate in, so brands and consumers are turning to adjacent categories like haircare, bodycare, and even oral care, where there’s more white space to do something interesting,” says Crossley.

Consumers are also willing to pay for it. According to McKinsey, hair loss prevention or reduction products are the number one haircare category consumers globally say they splurge on most, ahead of leave-in oils and serums. Hair loss supplements also rank highly.

The category has another commercial advantage: results take time, which can translate into months or even years of repeat purchasing. Hudson describes hair loss as an “ongoing outcome” space, where continuity matters and consumers are willing to spend more to find something they believe works. Once they do, trust creates “stickiness” and loyalty.

It also lends itself well to e-commerce: consumers can privately research a sensitive concern, compare ingredients and evidence, and subscribe to or replenish products online. A successful product can therefore become a gateway to a much longer — and potentially more lucrative — haircare relationship.

The question of efficacy

With opportunity, of course, comes opportunism. Search for “hair growth” today and the results will span supplements, scalp serums, and red-light helmets and devices, all promising varying degrees of thicker, stronger, or healthier hair.

But hair loss isn’t a single diagnosis. “It can be caused by multiple factors; it is important to understand the root cause to receive appropriate treatment,” says Gaboardi. Genetics, hormonal changes, nutritional deficiencies, stress, and rapid weight loss can all play a role — and what helps one consumer may do little for another. For beauty brands, that creates a challenge. Improving scalp condition, reducing breakage, or making existing hair appear fuller is not the same as stimulating new growth — and consumers are becoming more discerning about the difference.

SaunderBoots customers are increasingly shopping by ingredient and seeking out actives, with demand shifting toward more “science-backed and evidence-based” products. As the category gets more crowded, the ability to prove efficacy—rather than simply borrow scientific language—could separate long-term winners from those capitalizing on a trend.

Prevention is better than cure

Perhaps the biggest commercial opportunity, however, lies with those who aren’t losing their hair at all. “As we enter a new era of wellness, people have started to prioritize preventing hair loss and looking after their hair more,” says Gaboardi. With genetic hair loss, she says, intervening earlier offers a better chance of preserving existing hair before progressive miniaturization of the follicles makes significant regrowth harder.

It’s a familiar beauty playbook. Skincare has spent years shifting consumers away from treating visible signs of aging toward prevention and, more recently, skin longevity. Haircare is starting to do the same. The Future Laboratory’s Crossley describes it as part of a broader “pre-aging, prevention-first mindset” consumers increasingly apply to their appearance.

The language is changing, too. “Hair growth” and “hair loss” increasingly sit alongside softer—and far more universal—concepts like scalp health, density, and “hair longevity.” K18’s new serum is one example of the latter moving directly into product naming.

For businesses, the distinction matters. A product designed to treat hair loss speaks to those already experiencing it, while one that promises to maintain healthy, dense hair for longer can theoretically speak to almost anyone.

From hair loss to hair longevity

The next phase is also likely to become more targeted. McKinsey predicts a “much more segmented hair health ecosystem,” with solutions tailored to different types of loss—from temporary GLP-1-related shedding and perimenopausal thinning to male hair loss. Hudson also sees opportunity in designing products and delivery formats for a broader range of hair types and styles, including braids, locs, extensions, and curls and coils.

That could move the category away from the one-size-fits-all “hair growth” product toward something closer to personalized skincare: identify the concern, target its cause, and build a long-term regimen around it. With relatively few haircare brands currently offering hair-supportive supplements, there is also clear scope to expand beyond the bathroom shelf, creating an inside-out approach to hair health much like the one we have adopted for skin.

For an industry constantly searching for its next growth category, the potential is significant. The hair loss consumer is no longer just the person watching more strands than usual disappear down the shower drain. If beauty can convince shoppers to care for their future hair the way they already care for their future skin, the opportunity becomes considerably bigger: almost everyone who wants to keep the hair they have.
