Does Creatine Cause Hair Loss? A Canadian Supplement Store's Honest Answer

The Quick Answer:

"Will creatine make my hair fall out?" is one of the most common questions we get at the counter, right up there with bloating. It is a fair question, so let’s get into it. 

No direct, controlled evidence shows that creatine causes hair loss. The whole concern traces back to a single small study from 2009 that never actually measured hair, and the first trial to examine hair follicles directly, published in 2025, found no effect. Below is the full picture, including what it means if you are a woman, and what to do if you are still not convinced.

TL;DR

• The hair-loss worry comes from one small 2009 study that measured a hormone (DHT), not hair, and no study since has repeated that result.
• The first trial to look at hair follicles directly, in 2025, found no effect of creatine on hair or on hormones.
• If pattern baldness runs strongly in your family, the research still cannot rule the question out with total certainty, so it is fair to ease in and watch your own response.
• For women, more shedding around perimenopause is usually driven by dropping estrogen, not by creatine.
• Most "creatine did it" stories involve something else changing at the same time, like stopping minoxidil, starting several new supplements, or stress.
• Want to start gently? Skip the loading phase, begin at about 3 g a day, and consider a buffered creatine or a creatine hydrochloride (HCL)  form from Lift The City Supplements.

Where did the "creatine causes hair loss" fear come from?

It comes from one study: a 2009 trial on 20 college-aged male rugby players in South Africa. After a week of high-dose creatine loading, their DHT (a hormone linked to pattern baldness) rose about 56%. That single result launched years of speculation. It did not measure anyone's hair.

Here is what that study, by van der Merwe and colleagues in the Clinical Journal of Sport Medicine, actually did. Twenty rugby players took a 7-day creatine loading dose of 25 g a day, then 5 g a day for 14 days. Their testosterone did not change. But their DHT jumped 56% after loading and stayed around 40% above baseline through the maintenance phase, and the DHT-to-testosterone ratio climbed too.

That is a real hormonal shift, and it is why the concern is not complete nonsense. But three things get lost every time this study gets quoted:

• It never measured hair loss, hair density, or follicle health. The researchers were studying hormone ratios in athletes, not hair.
• It was small (20 people) and short (three weeks), with a big loading dose most people do not use.
• In more than 15 years, no study has directly replicated that DHT spike. In science, one unreplicated result is a starting point for more questions, not a conclusion.

What is DHT, and what does it actually have to do with hair loss?

DHT is short for dihydrotestosterone, a hormone your body makes from testosterone. In people who are genetically prone to pattern baldness, DHT can slowly shrink hair follicles over the years. But that only happens if your genes set you up for it, and that is the part that matters most.

Pattern hair loss, which doctors call androgenetic alopecia, runs in families. If you inherited follicles that are sensitive to DHT, more DHT can gradually thin them. If you did not, more DHT does not automatically cost you hair. And either way, it is a slow process that plays out over months and years, not days.

What does the latest research say?

The most important update happened in 2025: the first randomized controlled trial designed specifically to answer this question examined hair follicles directly and found no effect from creatine on hair or hormones. For over 15 years, the debate rested on a study that never checked hair. Now one has.

Published in the Journal of the International Society of Sports Nutrition (Lak et al., 2025), the trial gave 45 resistance-trained men aged 18 to 40 either 5 g of creatine or a placebo daily for 12 weeks, and 38 completed it. Researchers measured testosterone, DHT, the DHT-to-testosterone ratio, and, for the first time, hair follicle health, including density, follicular-unit count, and thickness. There were no significant differences between the creatine and placebo groups on any measure. This lines up with the broader evidence: a review of common misconceptions about creatine found no consistent change in testosterone or DHT across studies.

To be genuinely honest, the way we would talk to you at the counter, this study is not the final word either. It ran for 12 weeks, included only younger men, and excluded people already diagnosed with a hair-loss condition. So it cannot perfectly answer "what happens over five years in someone strongly predisposed?" But it is a large step up from a single hormone study on 20 rugby players, and it points clearly in one direction. (A nice detail for Canadian readers: one of the study's authors, Dr. Scott Forbes, is based at Brandon University in Manitoba.)

So does creatine cause hair loss or not?

Based on the current evidence, no, there is no direct proof that creatine causes hair loss in healthy adults. Testosterone does not rise, the one old DHT finding has never been replicated, and the first study to examine hair directly found nothing. The honest caveat: if you are genetically predisposed to pattern baldness, the DHT question cannot be closed with 100% certainty.

So the fair, complete answer is:

• For most people, the hair-loss worry is not supported by evidence.
• If pattern baldness runs strongly in your family and you are already noticing thinning, it is reasonable to be a little cautious and pay attention to your own response. Not because creatine is proven to cause loss, but because the research has not fully ruled it out for that specific group.

That is a very different message from "creatine is safe, stop worrying" and from "creatine will thin your hair." Reality sits in the honest middle.

Does creatine cause hair loss in women?

There is no evidence that creatine causes hair loss in women, and it is worth saying plainly: the research that started this conversation was done on young men, and pattern hair loss depends on individual genetic sensitivity. If you are in your 40s or 50s and noticing more shedding, the far more likely driver is the hormonal shift of perimenopause, not your creatine.

This matters because creatine has become one of the most talked-about supplements in women's health circles. The enthusiasm is real, but so is a recurring worry: "I read it might make my hair fall out."

Here is the piece that usually gets missed. As Cleveland Clinic explains, estrogen helps support hair growth and fullness, and when estrogen drops during menopause, hair often becomes thinner. That change is already underway for many women around this age, and it is easy to start creatine around the same time and connect two things that are not actually linked. If you are weighing creatine for women in perimenopause, the muscle and training reasons women talk about are worth taking seriously, and a hair fear the evidence does not support should not be the thing that stops you before you have looked at it. If your hair changes are bothering you, that is a conversation worth having with your doctor, who can identify what is genuinely going on.

What people online get wrong about creatine and hair loss

The big mistake online is treating "I started creatine, and then I shed" as proof that creatine caused it. Anecdotes feel convincing precisely because they are personal, but one person's timeline cannot separate creatine from everything else happening at the same time. That is not how you establish cause, and it is why the forums stay stuck in the same argument year after year.

Look closely at these stories, and there is almost always something else going on. Someone starts three new supplements at once and blames the creatine. Someone stops a hair treatment like minoxidil (a topical hair-loss product) the same month and blames the creatine. Hair shedding is part of a normal, ongoing cycle, and temporary shedding can be triggered by plenty of everyday things:

• Starting several new supplements at once, so nothing can be isolated.
• Stopping or changing a hair-loss treatment such as minoxidil, which can itself trigger shedding.
• Stress, illness, crash diets, or poor sleep.
• Normal seasonal shedding, which everyone experiences to some degree.

None of this means people's experiences are not real. It means the cause usually is not the creatine, and telling someone their experience is "a myth" helps no one. The honest read is: real shedding, real cause, just usually a different one. It is also worth remembering that DHT-driven hair loss takes months to years to show, not the days or weeks in which most online stories report shedding.

Still worried? How to start creatine cautiously

If you understand the evidence and still want to ease in, that is completely reasonable, and it is exactly what we would walk you through in person:

• Skip the loading phase. You do not need it. A steady daily dose saturates your muscles within a few weeks, and skipping loading also sidesteps most of the old DHT-spike concern (and most of the creatine side effects like bloating).
• Start at about 3 g a day.
• Consider a form that suits sensitive users. Sensitive users often prefer a buffered creatine like Kre-Alkalyn or a creatine hydrochloride (HCL), because both are taken at a smaller daily dose with no loading phase. That is a preference for tolerance, not a proven way to protect your hair.
• Watch your own response over a few weeks rather than trusting a stranger's timeline. You are the only relevant data point.
• The creatine we stock at Lift The City Supplements

If you just want the proven classic, plain creatine monohydrate from a trusted Canadian brand is hard to beat on value and research. If you are easing in cautiously, a buffered creatine or a creatine hydrochloride (HCL) is a gentler on-ramp. Here is how the options we carry compare:

A few honest notes. 

• PVL Gold Series is our Creapure pick: a Canadian brand using Creapure, a German-made creatine known for its purity.
• Perfect Sports Creatine is a clean, micronized Canadian monohydrate and our value pick, and it is third-party tested for WADA-banned substances, which matters if you compete in a tested sport. If you want creatine and electrolytes together, Perfect Sports Ultra Creatine + Electrolytes covers both.
• EFX Kre-Alkalyn is our go-to for sensitive users; it is a US-made buffered creatine, and when someone tells us regular creatine did not agree with them, it is usually the next thing we hand them.
• Tested Nutrition Creatine HCL is a capsule, so there is no mixing and no grit.
• ATP Labs Myoprime is a Canadian-made, flavoured option if you would rather mix and sip something with a bit more in it than plain creatine.

Frequently asked questions

1. Does creatine cause hair loss?
   
   There is no direct evidence that it does. The concern comes from a single 2009 study that measured DHT, not hair, in 20 men, and it has never been replicated. The first trial to examine hair follicles directly, in 2025, found no effect on hair or hormones.
   
   
2. Is creatine safe for women?
   
   Creatine is one of the most researched supplements available, and it is widely used by women. There is no evidence it causes hair loss in women. As with any supplement, if you are pregnant, nursing, or managing a health condition, check with your doctor first.
   
   
3. Does creatine increase DHT levels?
   
   One small 2009 study found a DHT increase after high-dose loading in young men. No study since has replicated it, and reviews of the broader research find no consistent change in DHT or testosterone from creatine.
   
   
4. Will creatine make my hair fall out if I am already thinning?
   
   There is no proof that it will. That said, if you are genetically predisposed to pattern baldness, the research cannot rule the DHT question out with total certainty, so it is reasonable to monitor your own response and speak with your doctor about what is driving the thinning.
   
   
5. Is creatine safe for women going through menopause?
   
   Creatine is popular in menopause communities, and there is no evidence it causes hair loss. Hair thinning around menopause is usually driven by declining estrogen and progesterone, not by creatine. A doctor can help pinpoint the actual cause if it is a concern.
   
   
6. Which creatine causes the fewest side effects?
   
   Most side effects, like bloating or stomach upset, come from high-dose loading, so skipping loading helps a lot. Buffered forms like Kre-Alkalyn and creatine HCL are often easier on sensitive users because they work at a smaller daily dose.
   
   
7. Should I stop taking creatine if I notice hair shedding?
   
   Shedding has many causes: stress, illness, seasonal changes, stopping a hair treatment, or hormonal shifts. If you are worried, it is worth reviewing everything that changed recently rather than assuming creatine, and checking with your doctor or dermatologist.
   
   
8. Does creatine affect women's hormones?
   
   Research has not shown creatine to meaningfully alter women's hormones. It works by helping your muscles produce energy, not by acting as a hormone.
   
   
9. How long does it take for creatine hair effects to show, if they happen?
   
   This is a big reason the myth persists: real DHT-driven hair loss develops slowly, over months to years, not within the days or weeks in which most online stories report shedding. That mismatch is a strong sign the two often are not connected.
   
   
10. Is Kre-Alkalyn better than creatine monohydrate for hair loss concerns?
    
    Neither form has been shown to cause hair loss, so it is not really about one being "safer" for your hair. People choose Kre-Alkalyn mainly for tolerance, a smaller dose, and no loading phase, not for hair reasons.
