Does Creatine Cause Hair Loss? What the Research Shows
You’ve probably seen the claim on Reddit, TikTok, or some fitness forum: creatine causes hair loss. It gets repeated so often that it feels like established fact. It isn’t.
The truth is simpler and less alarming than the internet makes it sound. One small study from 2009 found that creatine supplementation raised levels of a hormone associated with hair loss. That’s the entire body of evidence. No study has ever documented someone losing hair because they took creatine.
The single study linking creatine to DHT (a hormone that drives hair loss) was conducted in 2009 on 20 rugby players over 3 weeks. It has never been replicated, and the participants did not actually lose hair during the study.
Let’s walk through what actually happened, what it means, and whether you should care.
Where This Concern Comes From
One study. That’s it.
In 2009, researchers Van der Merwe, Brooks, and Myburgh published a study in the Clinical Journal of Sport Medicine. They gave creatine supplements to 20 college-age male rugby players in South Africa over three weeks. The protocol followed a standard loading and maintenance schedule.
The results showed that DHT (dihydrotestosterone) levels increased by roughly 56% after seven days of creatine loading. During the two-week maintenance phase that followed, DHT remained about 40% above baseline.
DHT (dihydrotestosterone) is the primary hormone responsible for androgenetic alopecia. It miniaturizes hair follicles over time, causing them to produce thinner and shorter strands until they stop producing visible hair entirely.
DHT is the hormone most directly linked to androgenetic alopecia, the medical term for genetic pattern baldness. So when this study came out, the internet did what the internet does. It connected two dots, skipped over all the context, and a myth was born.
Here’s what gets left out of every Reddit thread and YouTube thumbnail: nobody in the study lost any hair. The researchers weren’t even studying hair loss. They were looking at hormone responses to creatine supplementation. Hair was never measured, examined, or mentioned as an outcome.
Why One Study Isn’t Enough
Science doesn’t work on single data points. A finding only becomes meaningful when other researchers can reproduce it. Nobody has reproduced the Van der Merwe results in the 17 years since the study was published.
Think about the limitations:
The sample included just 20 people, all young male athletes playing the same sport. No control for diet, training intensity, sleep, stress, or genetic background. All factors that influence hormone levels.
The study measured DHT in the blood, not hair follicle response. Blood DHT levels and follicle sensitivity are two different things entirely.
The DHT increases, while statistically significant, stayed within normal physiological range. Your DHT fluctuates throughout the day based on exercise, food, sleep, and dozens of other variables.
No follow-up study has confirmed these findings. Several larger reviews of creatine research have looked for hormonal effects and found either no change or inconsistent results across studies.
One unreplicated study with 20 participants is not strong evidence for anything. It’s a preliminary observation that warranted further investigation. That investigation never produced supporting results.
How DHT and Hair Loss Actually Work
To understand why the creatine-hair-loss connection is so weak, you need to understand what DHT actually does to hair.
DHT is a potent androgen, a hormone derived from testosterone via the enzyme 5-alpha reductase. It plays important roles in development and is present in everyone’s body.
In hair follicles, DHT binds to androgen receptors. In people who are genetically susceptible to androgenetic alopecia, this binding triggers a process called follicular miniaturization. The follicle gradually shrinks. Each hair growth cycle produces a thinner, shorter, lighter hair than the one before. Eventually, the follicle stops producing visible hair altogether.
If you are concerned about creatine and hair, monitor your shedding for 3 months before and after starting supplementation. Take photos of your hairline monthly. This gives you actual data instead of anxiety based on internet speculation.
The key phrase there is “genetically susceptible.”
About 50% of men will experience some degree of androgenetic alopecia by age 50. A smaller but significant percentage of women are affected as well. The genetic component involves multiple genes, primarily related to androgen receptor sensitivity on the X chromosome, though other genes contribute too.
If you don’t carry the genetic predisposition, elevated DHT doesn’t cause hair loss. Your follicles simply don’t respond to the hormone in that way. Plenty of men with high DHT levels have full heads of hair their entire lives. And plenty of men with average DHT levels go bald in their twenties.
The relationship between DHT and hair loss is real, but it’s not as straightforward as “more DHT equals less hair.” Genetics determine whether your follicles are vulnerable. DHT is just the trigger, and only in those who are already predisposed.
What Dermatologists Actually Say
The dermatological consensus on creatine and hair loss is clear: there is no strong evidence connecting the two.
Dr. Robert Shapiro, a board-certified dermatologist and hair restoration specialist, has noted that the single study on creatine and DHT doesn’t provide anywhere near enough evidence to advise patients against using the supplement.
If you are genetically predisposed to hair loss (family history on both sides), consult a dermatologist before starting any supplement that may influence hormone levels. Prevention is far more effective than reversal.
The American Academy of Dermatology lists the causes and risk factors for androgenetic alopecia. Creatine supplementation is not among them. Genetics, age, and hormonal changes are the primary drivers.
Most dermatologists frame it this way: if you’re genetically predisposed to pattern baldness, it’s theoretically possible that anything raising DHT could accelerate the timeline slightly. Exercise itself raises DHT. Weight training raises DHT. Eating a high-protein diet can influence androgen levels. Nobody tells patients to stop exercising to prevent hair loss.
“Theoretically possible” is very different from “proven” or even “likely.” The theoretical risk from creatine, based on one small study, sits in the same category as dozens of other minor hormonal fluctuations your body experiences daily.
If a patient asks specifically about creatine, most dermatologists will say there’s no clinical reason to discontinue it based on current evidence.
The Broader Research on Creatine Safety
Creatine monohydrate is the most studied supplement in sports nutrition. Not one of the most studied. The most studied, period.
Hundreds of clinical trials have examined creatine’s effects across populations ranging from elite athletes to elderly adults to children with neurological conditions. The International Society of Sports Nutrition published a comprehensive position stand in 2017, authored by Kreider and colleagues, reviewing decades of accumulated research.
Their conclusion: creatine monohydrate is safe for both short-term and long-term use in healthy individuals. No consistent evidence of kidney damage, liver problems, dehydration, cramping, or any other serious adverse effect that gets attributed to creatine in gym folklore.
The supplement has been used by millions of athletes worldwide for over 30 years. If creatine caused hair loss at any meaningful rate, we would have noticed by now. Not through one small study, but through the kind of obvious, large-scale pattern that emerges when millions of people take something regularly.
Quitting creatine because of hair loss fears without checking your family history first is premature. If male pattern baldness does not run in your family, your risk from creatine is extremely low regardless of DHT levels.
That pattern doesn’t exist.
Should You Stop Taking Creatine?
This depends on your situation, and the answer is probably no.
If you’re not genetically predisposed to pattern baldness: There is no reason to worry. The evidence linking creatine to hair loss is thin to the point of being negligible. Continue supplementing if it benefits your training.
If you are noticing hair thinning and you take creatine: Stopping creatine probably won’t reverse the thinning. If your hair is miniaturizing, it’s almost certainly androgenetic alopecia progressing on its own timeline. This would be happening with or without the creatine.
That said, if discontinuing creatine gives you peace of mind, it’s a harmless experiment. Stop for three to six months and observe whether the rate of thinning changes. Creatine washes out of your system within a few weeks. If your hair loss continues at the same pace (it very likely will), you’ll have your answer.
The treatments that actually work for androgenetic alopecia are finasteride and minoxidil, both backed by extensive clinical research. Finasteride blocks the conversion of testosterone to DHT at the enzymatic level. Minoxidil stimulates blood flow to follicles and extends the growth phase of the hair cycle. Both are FDA-approved. Both have decades of data behind them.
Regardless of creatine use, the most effective early intervention for hair thinning is minoxidil (Rogaine). It is available over the counter and has decades of clinical evidence supporting its efficacy.
If you’re concerned about hair loss, those are the conversations worth having with a dermatologist. Whether you take creatine is, frankly, beside the point.
Signs of Actual Androgenetic Alopecia vs. Normal Shedding
Before you panic about any hair you see in the shower drain, know this: everyone sheds between 50 and 100 hairs per day. That’s normal turnover. Your hair grows in cycles, and shedding is part of the process.
Androgenetic alopecia looks different from normal shedding. Here’s what to watch for:
In men: A receding hairline that forms an M shape, often starting at the temples. Thinning at the crown that gradually expands. The hair in affected areas becomes finer and lighter before disappearing entirely. The sides and back of the head are typically unaffected.
In women: Diffuse thinning across the top of the scalp, usually with preservation of the frontal hairline. The part line widens. Hair density decreases gradually rather than creating bald patches.
The timeline matters too. Androgenetic alopecia is slow. It progresses over years, sometimes decades. If you’re losing large clumps of hair suddenly, that’s a different condition entirely (telogen effluvium, alopecia areata, or another cause) and requires immediate medical evaluation.
If you recognize the pattern of gradual miniaturization, see a dermatologist. Early intervention with proven treatments can slow or halt the progression significantly. But the cause is your genetics, not your pre-workout supplement.
Key Takeaways

- ✓ If you’re experiencing hair loss, see a dermatologist about proven treatments like finasteride and minoxidil.
Frequently Asked Questions
No. No study has ever documented hair loss as a result of creatine supplementation. The concern stems from one study that found creatine raised DHT levels, but DHT levels and hair loss are not the same thing. Hair loss from DHT requires genetic susceptibility, and even then, the connection to creatine remains unproven.
Creatine clears your system within a few weeks of stopping supplementation. However, if you’re experiencing androgenetic alopecia, stopping creatine is unlikely to change the rate of hair loss because the primary driver is genetic, not supplement-related. You can try stopping for three to six months to observe any difference, but set realistic expectations.
Yes. The International Society of Sports Nutrition’s 2017 position stand, based on decades of research across hundreds of studies, concluded that creatine monohydrate is safe for both short-term and long-term use in healthy individuals. No consistent adverse effects have been documented.
There is no evidence that creatine causes hair loss in women. The original 2009 study was conducted exclusively on young men. Women can experience androgenetic alopecia, but it follows a different pattern and is driven by genetics and hormonal factors, not supplementation.
The two FDA-approved treatments with the strongest clinical evidence are finasteride (a prescription oral medication that blocks DHT production) and minoxidil (a topical solution that stimulates follicle growth). Both are most effective when started early. Other options include low-level laser therapy and PRP (platelet-rich plasma) injections, though the evidence for these is less robust. Consult a board-certified dermatologist for a personalized treatment plan.
