Since GLP-1 medicine went mainstream within the early 2020s, there was rising consideration on the potential unintended effects, predominantly gastrointestinal disturbances resembling nausea, diarrhea and constipation.
Within the final three years, nevertheless, public curiosity within the affiliation between GLP-1s and hair loss has elevated markedly. This follows rising knowledge from pharmacovigilance research and up to date medical trials linking alopecia with weight reduction medicine.
For instance, a current examine printed within the British Medical Journal discovered the usage of GLP-1 receptor agonists was related with an increased risk of incident alopecia in adults with type 2 diabetes in comparison with two different diabetes medicine.
A big systematic assessment printed in Science Progress earlier this yr additionally concluded that GLP-1s, significantly semaglutide (Ozempic, Wegovy) and tirzepatide (Mounjaro) are associated with an increased risk of hair loss.
Now, new knowledge from consulting firm and end-to-end commercialization companion Ambileap reveals Amazon searches for hair development merchandise have sky-rocketed, greater than tripling since final yr.
“The expansion trajectory for hair development merchandise is distinctly steep,” mentioned Veronika Sianko, head of wellness and stimulation at Ambileap. “This explosive development took root round Q3 of 2025 (which recorded 802,432 searches) and has continued to surge aggressively since then, climbing to 1.4 million searches in This autumn 2025, 1.9 million in Q1 2026, and peaking at 2.5 million in Q2 2026.
“Finally, the [data] highlights that regardless of having decrease general search volumes than large classes like multivitamins, hair development presently possesses probably the most aggressive ahead momentum.”
What’s driving demand?
As with searches, the variety of hair development claims on product packaging is rising, too. Information from NielsenIQ (NIQ) reveals these claims have grown by 21% previously yr, making it one of many quickest rising claims within the beauty-from-within class.
In reality, the information suggests hair, pores and skin and nails is the most important well being want alternative inside the class, with close to common family penetration. The section additionally generated the best absolute greenback gross sales amongst all want states tracked, Sherry Frey, vice chairman of whole wellness at NIQ famous throughout a recent NutraIngredients webinar.
TikTok Store is a standard platform for customers to purchase hair development merchandise, she added, coming in second place general after vitamin and mineral dietary supplements, with hair care rising by 80% in comparison with one yr in the past. This rise seems to be linked to GLP-1 consumption.
“More and more, we’ve seen loads of development with GLP-1 customers and hair development merchandise due to hair loss,” Frey mentioned. “Nevertheless, it’s not essentially GLP-1 pushed–it may very well be speedy weight reduction or poor vitamin. There’s a wide range of components at play.”
Certainly, any type of speedy weight reduction may cause momentary hair loss. Analysis suggests it’s because speedy weight reduction is a significant stress occasion for the physique, inflicting vitality to be re-directed away from non-essential duties. An absence of sure vitamins resembling protein, iron and zinc also can result in an absence of hair manufacturing and shedding.
Hair loss can be brought on by a spread of different components, resembling stress and growing old. As well as, need for hair development merchandise may very well be attributable to social media and sweetness developments.
Nonetheless, a number of manufacturers hyperlink the rising demand for hair loss merchandise to the rising variety of customers on GLP-1 medicine. For instance, start-up Imaraïs Magnificence’s hero SKU is a scalp care product containing a mix of reishi, snow and chaga mushrooms, designed to spice up blood circulation to the scalp.
“Scalp care and hair regrowth is a big class due to GLP-1s,” mentioned Aaron Hefter, founder and president of Imaraïs Magnificence. “When you could have a client so dedicated to aesthetics and injecting themselves every day with these peptides, after which they begin dropping their hair, there’s an automated response. We’ve been within the area for 5 years, and we’ve seen an enormous spike over the past two years in our hair development complement, and we don’t see any finish in sight.”
Past mushrooms, biotin, thiamine, zinc and iron and nutritional vitamins B12 and C are widespread in hair development dietary supplements attributable to their means to provide keratin, assist the restore of hair tissue and combat mobile harm. Information from Ambileap reveals these vitamins are sometimes utilized in hair development formulation alongside proteins resembling collagen and amino acids, and botanicals resembling rosemary, pumpkin seed and nettle root.
Nevertheless, Ambileap’s Sianko famous that merchandise particularly designed for GLP-1 customers hardly ever carry hair development claims.
“An evaluation of GLP-1-supporting snacks and drinks launched within the US in 2025–2026 reveals that almost all tackle muscle loss, digestive discomfort, dehydration, low vitality and fatigue—hair well being isn’t cited as a profit,” she mentioned. “We estimate that not more than 5% of GLP-1-focused merchandise presently make hair-related claims.”
The image is analogous in Europe, in accordance with Nick Stene, senior international perception supervisor for client well being at Euromonitor, who mentioned hair loss has rising consciousness as a side-effect of extreme weight reduction, however the depth of well being merchandise aiming hair loss claims at GLP-1 assist audiences is at hint ranges solely to mid-2026.
This disconnect is demonstrated in mainstream retail settings. For instance, well being, magnificence and pharmacy retailer Boots has begun signposting customers to merchandise which might assist customers on their GLP-1 journey. Shelf barkers are getting used to spotlight points resembling pores and skin modifications, dry mouth, dehydration and bloating, pointing customers in the direction of merchandise which can assist alleviate these considerations. Nevertheless, hair development merchandise haven’t been signposted.
Extra specialised retailers, nevertheless, have begun to faucet into this rising development. Holland & Barrett’s on-line GLP-1 vary incorporates a vary of wholesome hair formulation, alongside protein, fiber and different merchandise for digestion, muscle assist, vitality and hydration.
GLP-1s and hair loss: What does the science say?
Researchers first started researching the affect of GLP-1 medicine on hair loss lower than a decade in the past. Because of this, there’s a pretty restricted analysis database exploring the hyperlink.
The assessment by Gupta et al. included 24 research which met the inclusion standards. From these research, the researchers famous that danger is most pronounced with semaglutide and tirzepatide, significantly at excessive doses.
Sufferers taking weekly subcutaneous doses of lower than 2 mg of semaglutide hardly ever reported hair loss. Nevertheless, incidence reached 7% in these taking 50 mg every day. Incidence additionally practically doubled—leaping from 2.5% to five.3%—in those that incurred extreme weight reduction, i.e. greater than 20% of their whole physique weight.
The researchers recommend the first driver of hair loss is subsequently unlikely to be drug toxicity however quite the secondary results of speedy, substantial weight reduction. Caloric restriction and dietary deficiencies have been additionally recognized as a contributor, with girls disproportionately affected, probably attributable to greater charges of weight reduction or elevated reporting sensitivity.
Additionally they highlighted that there are presently no human research suggesting GLP-1s have a straight dangerous impact on hair follicles.
The medical trial by Tang et al. reached comparable conclusions. The methodology differed from most earlier research, evaluating GLP-1 receptor agonists with sodium-glucose cotransporter-2 (SGLT-2) inhibitors and dipeptidyl peptidase-4 (DPP-4) inhibitors (widespread diabetes drugs) in kind 2 diabetes sufferers.
Total, these on GLP-1 drugs had a 37% greater danger of hair loss in comparison with these on SGLT-2 inhibitors and a 68% greater danger in comparison with these on DPP-4 inhibitors. Nevertheless, after adjusting for affected person variations, absolutely the danger was low, with solely round six to seven individuals per 1,000 growing clinically recorded hair loss.
As well as, the researchers discovered that the danger was virtually solely tied to non-scarring types of alopecia, primarily telogen effluvium (TE), which started through the first yr of therapy.
TE happens when a systemic shock prematurely flips a lot of follicles from the expansion section (anagen) right into a resting section (telogen), resulting in diffuse shedding months later. This usually signifies that hair development will return as soon as the physique has overcome the stress of speedy weight reduction.
The researchers of the BMJ examine, like these of the assessment, concluded that hair loss is extra possible induced by speedy weight reduction quite than by the drug itself.
“The most definitely mechanism underlying the noticed affiliation between GLP-1 receptor agonist use and alopecia pertains to weight reduction and diminished caloric consumption following therapy initiation,” they wrote. “Caloric restriction might also contribute to physiological stress and micronutrient deficiencies (for instance, iron, zinc, biotin), which might disrupt the hair development cycle. This aligns with the predominance of non-scarring alopecia noticed in our examine and means that hair loss might mirror downstream results of metabolic change quite than a direct drug impact.”
Tang et al. reported that these findings might have vital medical implications, significantly if they supply reassurance to GLP-1 customers that hair loss is a possible, however not common, consequence of weight reduction medicine. And when it does happen, it’s prone to be a brief aspect impact quite than a everlasting final result.
“Additional research are wanted to make clear underlying mechanisms, assess medical severity and reversibility, and establish sufferers who could also be at greater danger,” they concluded.
