Does Creatine Cause Hair Loss? What the Research Says in 2026

Creatine has been studied to death, yet one question keeps following it around: does it make you lose your hair? Spend five minutes on Reddit, TikTok or Instagram, and you will find plenty of men convinced their shedding started after taking creatine, while others dismiss the whole thing as an old gym myth that should have disappeared years ago.

The fear mostly comes from a small 2009 study that found an increase in DHT after creatine supplementation, which got people's attention because DHT plays a major role in male-pattern hair loss. The study never measured hair loss itself, though, and for years that left a big gap between the theory and what was happening on people's heads. In 2025, researchers finally ran a randomized trial that measured both hormone levels and the hair directly, giving us a much better answer than the one the internet has been arguing over for the last fifteen years.

Quick Answer

Current research does not show that taking creatine causes hair loss. The concern comes mainly from a small 2009 study of rugby players that reported higher DHT during three weeks of supplementation, but it did not measure shedding, hair density or follicle health.

The much more relevant 2025 randomized controlled trial gave resistance-trained men five grams of creatine or placebo every day for 12 weeks and measured both their hormones and their hair. Researchers found no significant differences in DHT, hair density, follicular units or cumulative hair thickness between the groups. It is reassuring evidence rather than absolute proof for every man and every length of use, since the study was fairly small, lasted 12 weeks and did not specifically recruit men with known androgenetic alopecia.

The Hair-Loss Theory Started With DHT

The study behind most of the concern was published in 2009 and followed 20 college-aged rugby players who used a loading phase of 25 grams of creatine per day for seven days, followed by five grams per day for another 14 days. Researchers were measuring testosterone and dihydrotestosterone, better known as DHT, rather than trying to investigate baldness. You can read the original study here.

DHT increased during the creatine phase, and the result attracted attention because DHT is strongly involved in androgenetic alopecia. In genetically susceptible men, androgen signalling gradually miniaturises scalp follicles, which is also why treatments such as finasteride work by reducing the conversion of testosterone into DHT. A good overview of that mechanism is available in this review of androgenetic alopecia and DHT.

From there, “creatine increased DHT in one small study” slowly turned into “creatine makes you bald.” The original research never showed that. Hair density was not measured, follicles were not examined and the experiment lasted only three weeks, so there was no way to know whether the hormonal change had any meaningful effect on hair.

Later creatine research did not establish a consistent rise in DHT either. A 2021 review of common creatine misconceptions looked at the available evidence and concluded that it did not support the claim that creatine causes hair loss. The frustrating part was that researchers were still arguing mostly from hormone data, because nobody had properly run the obvious experiment and measured the hair itself.

We had already mentioned the claim in our guide to common gym myths, but the newer study gives us a much better reason to revisit it now.

The 2025 Study Looked at What Was Happening to the Hair

The 2025 trial recruited 45 resistance-trained men aged 18 to 40 and randomly assigned them to five grams of creatine monohydrate or five grams of maltodextrin placebo per day. Thirty-eight completed the 12-week study, and the researchers used blood tests alongside trichogram analysis and FotoFinder imaging rather than relying on hormone levels as a proxy for what might be happening on the scalp.

They measured total testosterone, free testosterone and DHT, then looked directly at hair density, follicular unit count and cumulative hair thickness. None of those measurements differed significantly between the creatine and placebo groups after 12 weeks, including DHT itself.

For the question men are asking, that makes this trial far more useful than the old rugby study. Instead of finding one hormonal change and speculating about what it might eventually do to somebody's hair, the researchers checked whether normal daily creatine supplementation was accompanied by measurable deterioration in the hair and found no evidence that it was.

There are limitations worth keeping in mind without pretending they cancel the result. Twelve weeks cannot tell us exactly what happens after several years of continuous supplementation, family history of androgenetic alopecia was not recorded, and the trial did not specifically recruit men whose follicles were already known to be highly sensitive to androgens. The authors also reported no specific external funding for the study, although several disclosed previous relationships with sports-nutrition and supplement companies through advisory work, research support or product donations.

What we have, then, is a decent controlled trial pointing in a reassuring direction, not a lifetime guarantee for every genetically susceptible man.

Why Men on Reddit Still Swear Creatine Made Them Shed

The newer research has not killed the discussion because plenty of men remain convinced that their own experience says otherwise. A recent r/tressless thread came from somebody who said he had tried creatine several times and noticed increased shedding each time, while another discussion questioned whether the newer studies are enough for men who already know they are prone to androgenetic alopecia. There are also people on the other side, including a recent personal report from someone who had avoided creatine because of the hair-loss fear and later used it without noticing increased shedding.

It is easy to understand why this particular supplement produces such strong reactions. Hair loss is already one of the biggest insecurities for a lot of men, and online discussion around receding hairlines, finasteride, minoxidil and hair transplants has become enormous. If somebody begins taking creatine and starts noticing more hair in the shower a few weeks later, blaming the new supplement is a natural conclusion.

The difficulty is proving that the two events are connected. Male-pattern hair loss is extremely common, develops gradually and is heavily influenced by genetics, which means somebody's hair may already have been thinning when creatine entered the picture. Shedding can also change for reasons unrelated to androgenetic alopecia, including illness, significant stress, calorie restriction and other forms of hair loss. The American Academy of Dermatology's overview of male-pattern hair loss is useful here because it shows how many variables sit behind what looks, from the outside, like the same problem.

That does not make the Reddit experiences worthless. If somebody starts creatine, notices a change, stops, improves and then reports the same pattern after trying it again, that is interesting enough to justify asking whether a subgroup of genetically susceptible men deserves more specific research. What it cannot do is establish causation by itself, especially when controlled research has so far failed to show the same effect.

Should You Take Creatine If Hair Loss Worries You?

For most healthy men, the evidence we have does not give a strong reason to avoid creatine because of baldness. Five grams per day is one of the standard researched doses, and creatine has a much stronger evidence base for improving strength and lean-mass outcomes than it has evidence connecting it to hair loss.

At the same time, creatine is useful rather than essential. If you already have noticeable thinning, a strong family history of androgenetic alopecia or you start seeing a convincing change in shedding after introducing it, nobody is forcing you to keep taking it while you stare at the shower drain every morning. Stopping the supplement and speaking to a dermatologist is a perfectly reasonable response, particularly because early treatment matters far more for male-pattern hair loss than proving whether one tub of creatine had anything to do with it.

For anyone taking creatine mainly because they want to build more muscle, it is also worth keeping the supplement in proportion. Progressive training, sufficient calories, protein and recovery are doing most of the work. Our beginner muscle-building guide covers those fundamentals, while we have separate guides on how close you really need to train to failure and whether protein timing around your workout matters.

Final Verdict

Based on the evidence available in 2026, creatine has not been shown to cause hair loss. The theory began with a small 2009 study that found an increase in DHT without measuring anyone's hair, while the first randomized trial to measure both hormones and actual hair outcomes found no significant difference in DHT, hair density, follicular units or cumulative hair thickness after 12 weeks of five grams per day.

There is still room for longer studies and research focused specifically on men who are strongly predisposed to androgenetic alopecia, which would help answer the part of the Reddit debate that the current trial cannot completely settle. Until that evidence exists, though, the idea that ordinary creatine use makes men go bald is much stronger online than it is in the research.
