Does Creatine Cause Hair Loss? Evidence

There is no good evidence that creatine causes hair loss. No clinical trial has ever documented increased shedding, reduced hair density or follicle miniaturisation attributable to creatine monohydrate. The fear traces back to a single small 2009 study that measured hormones in the blood and never once counted a hair.

That is the short answer. But if you have started training, started creatine, and then noticed more hair in the drain, "there is no evidence" is not a satisfying reply — you saw what you saw. So this piece does two things: it walks through the actual evidence trail properly, including the 2025 trial that finally measured hair itself, and it deals honestly with why the timing lines up so convincingly for Indian men in particular.

Where the fear came from: the 2009 rugby study

In 2009, van der Merwe, Brooks and Myburgh published a small study in the Clinical Journal of Sport Medicine, titled for what it actually measured: the effect of three weeks of creatine monohydrate on the dihydrotestosterone-to-testosterone ratio in college-aged rugby players. It was a double-blind, placebo-controlled crossover trial with a six-week washout, run at a rugby institute in South Africa during the competitive season. Twenty players loaded with 25 g of creatine plus 25 g of glucose per day for seven days, then took a maintenance dose of 5 g of creatine plus 25 g of glucose per day for fourteen days. Serum testosterone and dihydrotestosterone (DHT) were measured at baseline, day 7 and day 21.

Here is the single most important fact about that study, and it is the one every fear-driven forum post leaves out: it never measured hair. No hair count. No density. No shedding rate. No follicle assessment. Nobody in the trial was reported to have lost hair, because hair was never an outcome. The study measured a hormone that is associated with baldness in genetically predisposed people, and the internet did the rest.

The numbers themselves are not in dispute, so here they are as the paper reports them. Serum testosterone did not change. DHT rose by 56% after seven days of creatine loading and remained 40% above baseline after fourteen days of maintenance (P < 0.001). The DHT-to-testosterone ratio rose by 36% after the loading week and was still 22% above baseline after the maintenance dose (P < 0.01). The authors' own conclusion was appropriately cautious: creatine may, in part, act through an increased rate of conversion of testosterone to DHT, and further investigation is warranted. They did not claim creatine had been shown to cause anything.

Those percentages are real, and they are also the entire empirical basis of the hair-loss fear. Four things constrain what they can carry. It was a single small study of twenty players. It has never been replicated in the years since. DHT measured in blood is a proxy, not a hair outcome. And nothing was measured on the scalp, over any timescale, to connect the two.

Creatine is not a hormonal agent, and the International Society of Sports Nutrition's 2017 position stand does not treat it as one. Discussing use in young athletes, it describes creatine monohydrate as "a nutritional alternative with a favorable safety profile to potentially dangerous anabolic androgenic drugs". That is the document's own wording, and it is a comparison rather than a measurement: the position stand reports no testosterone or DHT figures and does not mention hair loss at all.

We should be equally straight about what does not exist. There is no meta-analysis of creatine and testosterone, and none of creatine and hair loss. If you see one cited — including in any earlier version of this page — it is a citation to something that was never published. The evidence on creatine and androgens consists of individual trials, chiefly the 2009 rugby study above and the 2025 trial below, and it deserves to be weighed as exactly that.

The mechanism, explained without overclaiming

The reason a DHT signal alarmed people is that the mechanism is genuinely real. Testosterone is converted to DHT by the enzyme 5-alpha-reductase. In people who carry the genetic predisposition for androgenetic alopecia, DHT binds to receptors in scalp follicles and drives miniaturisation — follicles produce progressively finer, shorter hairs until they stop producing visible hair at all. That pathway is well established for male-pattern baldness in general.

What has never been shown is that creatine moves DHT far enough, or for long enough, to matter at the follicle. State it precisely and the whole thing gets clearer: the mechanism is real; the link from creatine to that mechanism is not established.

The 2025 trial that actually counted hair

In 2025, Lak and colleagues published a randomised, double-blind, placebo-controlled trial in the Journal of the International Society of Sports Nutrition, titled directly: does creatine cause hair loss? Thirty-eight resistance-trained men aged 18-40 completed it (45 were recruited, 19 per group finished), training at least three times a week, taking either 5 g/day of creatine monohydrate or 5 g/day of maltodextrin placebo for twelve weeks.

On hormones: total testosterone rose and free testosterone fell across the twelve weeks in both groups, but these changes were independent of supplementation, and there were no significant differences between groups in DHT, the DHT-to-testosterone ratio or the DHT-to-free-testosterone ratio. The 2009 finding did not reappear.

What makes this trial new is that it measured hair itself — hair count, hair density, anagen and telogen rates, follicular units, terminal versus vellus hair percentages, and cumulative hair thickness. The paper reports no statistically significant effect of group, time, or group by time on any of them. This is the first trial to test the question directly rather than inferring it from a blood sample.

What the 2025 trial cannot tell you

Being straight about this matters more than winning the argument. The authors list the limits themselves: the sample was male only; twelve weeks is short when male-pattern baldness unfolds over years; hormones were sampled in plasma, not at the scalp or follicle; and family history of hair loss was not assessed — so the trial cannot speak directly to the genetically predisposed man who is most worried in the first place. Thirty-eight completers is small.

The honest conclusion is "no evidence of harm in a well-designed short trial", not "proven safe forever". Anyone selling you either certainty is selling you something. It is also worth noting that the 2009 DHT finding has never been replicated. Cleveland Clinic puts it this way: no study has been able to recreate those results, and of twelve further studies that examined creatine's effect on testosterone, none reported significant hormonal increases.

The Indian timing problem nobody talks about

Here is the part missing from every page an Indian reader finds on this question. Androgenetic alopecia is common in Indian men, and it establishes itself early. The firmest Indian figures come from a population-based study of 1,005 men aged 30 to 50 at Manipal Hospital, Bangalore: 47.5% already had pattern alopecia in the 30-35 band, rising to 58.7% at 36-40 and 73.2% at 41-45. That study did not enrol anyone under 30, so it cannot tell us the rate among men in their twenties, and we have not found an Indian population study that reliably does. Percentages circulating for under-30s trace back to hair clinics rather than to published research, so we will not repeat them. What the published data does establish is blunt enough: by the opening of the thirties, close to half of Indian men are already affected.

Now look at when Indian men typically join a gym, get told by a trainer to start creatine, and begin studying their hairline in a brightly lit gym mirror. It is the same window. Two unrelated things start at the same time, and one gets blamed for the other. The correlation you observed is real. The causal arrow is the part that was assumed.

What else sheds hair right when you start training

If you are shedding, these are the candidates a dermatologist would actually work through — and several are common in India specifically:

Telogen effluvium. Diffuse shedding triggered by a stressor — a viral illness, surgery, severe stress, a crash diet — that shows up on a two to three month delay. That delay lands suspiciously close to most creatine start dates.
Aggressive cutting. Steep calorie deficits and rapid weight loss are a well-recognised trigger for shedding, and cutting phases usually begin around the same time as supplementation.
Low ferritin. Genuinely common on dal-roti-paneer-rajma vegetarian diets, particularly when tea or coffee is taken alongside meals, which blunts non-haem iron absorption.
Low vitamin D and thyroid dysfunction. Both widespread in India despite the sunshine, and both worth a blood test rather than a guess.
Seasonal and environmental factors. Summer heat, heavy sweating, daily washing and hard borewell water in many Indian cities affect hair texture and breakage. These are what people actually discuss, and they deserve naming even if they are not the main driver of patterned loss.

None of these is a reason to dismiss what you noticed. They are reasons to test rather than to blame the newest thing in your kitchen shelf.

A quality question that is not a hair claim

There is one version of "my supplement affected my hair" that deserves respect. Supplements are not pre-approved the way drugs are. An adulterated or mislabelled product could plausibly contain undeclared actives — so a claim can be true of a specific tub without being true of creatine monohydrate. Cleveland Clinic dietitian Kate Patton makes the adjacent point that buyers should choose third-party tested products precisely because supplements are not regulated like medicines.

In India this is not theoretical. Cheap unbranded creatine circulates on marketplaces with no verifiable licence and no lab report. If you are spending ₹999 on a 250g jar, you are entitled to know what is in it: a real FSSAI approved creatine licence you can look up (Coremax carries manufacturing licence 10723999001935 and marketing licence 10725994000807), third-party lab testing, and a per-jar authentication code you can verify. Being made in India creatine from a HACCP/GMP/ISO facility means the paperwork is checkable rather than imported and opaque. That is a purity argument, not a hair-loss claim — no creatine, ours included, prevents or treats hair loss. If you want the method, our guide on how to check creatine purity and our breakdown of choosing creatine in India cover it properly.

Frequently asked questions

Can creatine cause hair loss?

On current evidence, no. No trial has recorded creatine causing shedding, thinning or follicle miniaturisation, and the only trial to measure hair directly found no effect over twelve weeks. Long-term data in genetically predisposed men is still missing, so the accurate phrasing is "no evidence of harm", not "impossible".

Is hair loss from creatine permanent?

The question assumes a cause that has not been demonstrated. If your hair is thinning, the driver is more likely androgenetic alopecia, telogen effluvium, low ferritin or a thyroid issue — and whether it is reversible depends entirely on which of those it is. That is a dermatologist's call, not a supplement question.

Will my hair grow back if I stop taking creatine?

Stopping creatine does not address a cause that has not been established. If you stop and shedding continues, that is useful information: something else was always driving it. We would avoid the framing used by clinics that market treatments — "stop creatine and it reverses" quietly presupposes the causation the evidence does not support.

How do I prevent hair loss from creatine?

There is no creatine-specific precaution to take, because there is no established creatine-specific risk. What is worth doing regardless: get ferritin, vitamin D and thyroid checked if you are shedding, avoid extreme calorie deficits, and see a dermatologist early if the loss is patterned or rapid — early-onset androgenetic alopecia responds better to early assessment.

Does creatine increase DHT?

One 2009 crossover study of 20 rugby players reported DHT rising 56% after a seven-day loading protocol and remaining 40% above baseline after two weeks of maintenance, with the DHT:T ratio up 36% and then 22%. It has never been replicated, and the 2025 randomised trial found no significant difference in DHT or the DHT:T ratio between creatine and placebo over twelve weeks at 5 g/day. Note the gap that remains either way: a change in a blood hormone is not a change in hair, and no trial reporting raised DHT has measured a hair outcome alongside it.

Does creatine increase testosterone?

The evidence says no, though it is thinner than people assume. In the 2009 rugby study, serum testosterone did not change. In the 2025 twelve-week trial, total testosterone rose and free testosterone fell in both groups over time, but those shifts were independent of supplementation — creatine made no difference to either. There is no meta-analysis on the question, so treat this as a consistent finding across small trials rather than a settled one.

Is creatine safe if I have a family history of baldness?

There is no evidence it is harmful, but be aware of the gap: the 2025 trial did not record family history, so it cannot speak directly to that group. If you carry a strong family history, the sensible move is to see a dermatologist about the predisposition itself — which will progress on its own schedule with or without creatine — rather than treating the supplement as the variable.

Should I stop creatine if my hair is thinning?

You can stop if it eases your mind; nothing is lost but the training benefit. A more useful step is getting the thinning assessed, because patterned loss caught early has better options than patterned loss caught late. For the daily-use question generally, see our post on whether creatine is safe to take daily.

Does creatine cause hair loss in females?

There is even less reason to think so, and even less data. The 2009 and 2025 studies were both male-only, so no trial has tested this question in women at all. Female pattern hair loss and telogen effluvium in Indian women are frequently linked to iron deficiency, thyroid disorders and PCOS, all of which warrant a proper workup.

Is there a creatine that doesn't cause hair loss?

No form of creatine has been shown to cause hair loss, so no form can claim to avoid it. Ignore any product marketed on that basis. What you should actually compare is purity, licensing and testing — that is a real difference between products; hair claims are not.

The bottom line

The evidence points one way: creatine monohydrate has not been shown to cause hair loss, and the only trial that measured hair directly found nothing. It also has real limits — small, short, male-only, and silent on family history. Both things are true, and you deserve to hear both. For the wider picture on cramps, kidneys, bloating and the rest, our overview of creatine side effects is the summary; this piece is the deep dive on the one question that scares people most.

This article describes what the research shows and is not medical advice. If your hair is thinning, receding or shedding rapidly, see a dermatologist. Creatine does not treat, cure or prevent hair loss of any kind, and no supplement is a substitute for that assessment.

On creatine itself, Cleveland Clinic notes there is not enough evidence to establish safety in people who are pregnant or breastfeeding, or who have kidney disease, liver disease or diabetes, and advises talking to a healthcare provider before starting creatine if you take medication or other supplements. Adolescents should use it only with adult and clinical oversight. None of that is cause for alarm — creatine monohydrate has a long safety record in healthy adults — but if you are in one of those groups, ask your doctor rather than guessing.
