Does Creatine Cause Hair Loss? The DHT Connection Explained

1. Does creatine cause hair loss?

There is no good evidence that it does. The claim exists because of a single 2009 trial that found a rise in a hormone linked to hair loss, without measuring hair. The one controlled trial that has since measured hair, a 2025 study by Lak and colleagues, found no effect. In that 12-week trial, 45 resistance-trained men took 5 g a day of creatine or a placebo. Hair density, follicular unit count and hair thickness, assessed by trichogram and FotoFinder imaging, did not differ between groups, and neither did DHT or the DHT to testosterone ratio.

That is not the same as proof for every person. The 2025 trial was short, enrolled young men only, and 38 of the 45 finished. Still, a plausible mechanism was raised, it was tested directly, and the safety reviews have not identified hair loss as a documented effect of creatine. If you are anxious about balding, you do not need to avoid creatine on the strength of one hormone study.

2. Where the DHT story came from

In 2009, van der Merwe and colleagues in South Africa studied 20 college-age rugby players in a double-blind crossover design. For seven days the men took a creatine loading dose of 25 g a day, then 5 g a day for 14 more days, and on another occasion took a placebo. Blood tests showed that testosterone did not change. Dihydrotestosterone (DHT), a more potent androgen made from testosterone, rose by 56 percent after the loading week and stayed 40 percent above baseline after the maintenance weeks. The DHT to testosterone ratio rose too.

DHT matters for hair because in people who are genetically sensitive to it, DHT shrinks scalp follicles over years, producing male pattern baldness (androgenetic alopecia). That is why the finding spread so fast.

But the study did not look at hair at all. It measured hormones for three weeks in 20 athletes, during a competitive season, which can itself alter hormones. The authors themselves said that more research was needed. A higher serum DHT does not automatically mean more DHT acting at the scalp, and the follicle's own sensitivity is what decides whether thinning occurs.

3. What happened after that study

For years there was little follow-up. Reviews of creatine safety, including the International Society of Sports Nutrition position stand and a 2021 paper by Antonio and colleagues on common misconceptions about creatine, do not list hair loss as an established effect. Then, in 2025, Lak and colleagues ran the first randomised trial to measure hair directly. Forty-five resistance-trained men aged 18 to 40 took 5 g a day of creatine monohydrate or placebo for 12 weeks. Total testosterone, free testosterone and DHT were measured in blood, and hair follicle health was assessed with a trichogram and FotoFinder imaging. There were no group differences in DHT, the DHT to testosterone ratio, hair density, follicular unit count or hair thickness. The authors described it as strong evidence against the claim.

One more limit is worth stating. Most creatine studies are short and measure muscle, not hair, and hair loss is slow. A reaction that takes years to show up could be missed in a trial lasting 12 weeks, as the 2025 one did. That is a reason for continued research, not a reason to assume harm.

It is also worth noting that the 2009 trial's loading dose, 25 g a day, is far above the 3 to 5 g a day that most people use. The 2025 trial suggests it does not appear at 5 g a day. Our guide to the creatine loading phase explains why loading is optional.

4. Who might worry, and who probably should not

Androgenetic alopecia is mainly genetic. It tends to run in families, often shows as a receding hairline and thinning at the crown in men, and in women as diffuse thinning along the parting. If your father and grandfather went bald early, you already carry the higher risk, and that risk exists whether or not you lift weights.

If you have a strong family history and are noticing early thinning, a reasonable approach is to treat creatine as an unlikely cause, while remembering that the 2025 trial lasted only 12 weeks. You could speak to a dermatologist, watch whether anything changes over several months, and stop creatine for a trial period if it concerns you. Treatments such as finasteride, which blocks DHT production, are prescribed medicines and a doctor's decision.

If you have no family history and no thinning, there is little reason to worry. Note too that women have far lower androgen levels, and there is no data suggesting creatine causes hair loss in women. Our creatine guide for women covers use in more detail.

For men who are already losing hair and use creatine, the practical difficulty is that you cannot separate the two causes by looking in the mirror. Hair loss from genetic sensitivity advances slowly and usually in a recognisable pattern, while shedding from a dietary or medical trigger tends to be diffuse and to come on over a few weeks. A dermatologist can often tell the difference with a scalp exam and a simple pull test.

5. Other reasons you may be shedding hair after starting creatine

People often begin creatine at the same time as a new training and diet regime, and several things that happen alongside it cause genuine hair shedding:

• A crash diet or fast weight loss. Cutting calories hard, or losing weight rapidly, can trigger telogen effluvium, a diffuse shedding that shows up two to three months after the trigger.
• Low iron or ferritin. Common in Indian women, and in people who eat little red meat or who train hard.
• Low vitamin D and vitamin B12. Both are widespread in India, especially in vegetarians for B12.
• Low protein intake. Hair is made of protein, and poor intake during a cut can reduce hair growth.
• Thyroid disorders, illness and chronic stress. All can shed hair, and they are easy to miss.

Because of this timing overlap, creatine is easy to blame. If you notice more hair on your pillow or in the drain, a blood test for ferritin, vitamin D, B12 and thyroid function is more informative than stopping a supplement. Our post on protein needs is useful if you suspect your intake is low.

It also helps to know that a change in a blood hormone does not map neatly onto the scalp, because the body regulates how much DHT reaches tissues through enzymes and receptors that differ from person to person. The 2009 trial did not report any hair outcome, and the 2025 trial, which did, found none. That makes the headline figure less alarming.

6. What to do if you are worried

A calm, practical approach is better than either ignoring the concern or dropping a useful supplement.

1. Look at your family history. Early balding in close relatives is the single best predictor.
2. Use 3 to 5 g a day and skip the loading phase, which keeps the dose well below the amount used in the 2009 study.
3. Take photos of your hairline and crown every month under the same lighting, so you can tell real change from day-to-day variation.
4. See a doctor or dermatologist if you are shedding heavily, have patchy loss, a scalp rash, or lose hair as a woman or a young adult.
5. If you decide to stop creatine as a test, give it three to six months, because hair cycles are slow.

7. Frequently Asked Questions

Q1: Will creatine make me go bald?

A1: There is no good evidence that it will. If you are genetically prone to pattern baldness you will probably get it with or without creatine. The only data linking creatine to the hormone DHT came from a small 2009 study that did not measure hair, and a 2025 randomised trial that did measure hair found no change.

Q2: Does creatine raise DHT?

A2: One study of 20 rugby players found DHT was 40 to 56 percent higher on creatine, with testosterone unchanged. That used a loading dose of 25 g a day for a week. A 2025 randomised trial of 45 men taking 5 g a day for 12 weeks found no rise in DHT and no change in hair.

Q3: Should I stop creatine if my hair is thinning?

A3: Check the common causes first: ferritin, vitamin D, B12, thyroid, crash dieting and stress. If those are normal and you still want to test creatine, stop for three to six months and see what changes, ideally with a dermatologist's advice.

Q4: Is creatine safe for women regarding hair loss?

A4: There is no evidence of hair loss from creatine in women, and women have much lower androgen levels than men. Diffuse thinning in women is more often linked to iron deficiency, thyroid problems, postpartum changes or dieting.
