Does Creatine Cause Hair Loss? What the 2026 Research Actually Shows

No, current research does not show that creatine causes hair loss. The strongest evidence so far comes from a 2026 randomised controlled trial in resistance-trained men. After 12 weeks of taking 5 g of creatine monohydrate daily, researchers found no significant difference in DHT, hair density, follicular units or hair thickness compared with placebo.

That is worth knowing because the creatine-hair loss debate spent years resting largely on one small study from 2009. It measured hormones, not hair.

Key Takeaways

• Current evidence does not show that creatine causes hair loss.
• A 2026 controlled trial directly examined hair follicles for the first time and found no adverse effect.
• The original concern came from a 2009 study of rugby players that reported higher DHT after creatine supplementation.
• That older study involved only 20 participants and never measured hair loss.
• Genetic sensitivity to DHT, rather than DHT alone, is central to androgenetic alopecia.
• If your hair is thinning while taking creatine, do not automatically assume the supplement is responsible. Hair loss has many possible causes.

How Does Creatine Work?

Creatine works by increasing the phosphocreatine stored in your muscles, which helps your body regenerate ATP during short, high-intensity exercise. ATP is the immediate energy source your muscles use for activities such as lifting and sprinting. By making this rapid energy system more readily available, creatine can support repeated high-intensity efforts, strength and training performance. Your body produces creatine naturally, and you can also obtain it from food or supplements.

The 2026 Randomised Controlled Trial: The Study That Changes the Conversation

For years, one obvious piece was missing from the creatine and hair loss debate: nobody had actually measured what happened to people's hair.

That changed in 2026.

Researchers recruited 45 resistance-trained men aged 18 to 40 and randomly assigned them to either 5 g of creatine monohydrate per day or 5 g of maltodextrin as a placebo. Thirty-eight participants completed the 12-week study.

Blood tests measured total testosterone, free testosterone and dihydrotestosterone, better known as DHT.

More importantly, researchers assessed the hair itself. They used a Trichogram and FotoFinder system to measure hair density, follicular unit count and cumulative hair thickness.

The result was pretty straightforward.

There were no significant differences between creatine and placebo for DHT, the DHT-to-testosterone ratio or any of the measured hair outcomes.

This was also a standard 5 g daily creatine dose rather than an unusually small amount.

There are limitations. The study lasted 12 weeks, included men only and did not specifically recruit participants based on family history of androgenetic alopecia. It cannot tell us what happens in every person over several years.

Still, it is the first controlled trial to look directly at both hormones and hair-follicle health. That makes it much more relevant to the question "does creatine cause hair loss?" than studies measuring hormones alone.

Where the Creatine Hair Loss Myth Came From

The concern can largely be traced to a 2009 study involving 20 college-aged male rugby players.

Participants used a loading protocol of 25 g of creatine per day for seven days, followed by 5 g daily for another 14 days.

After the loading period, DHT had increased by 56% from baseline in the creatine group. After the maintenance period, it remained roughly 40% above the group's starting level.

Those numbers sound alarming without context.

The researchers did not measure hair shedding, hair density, follicle size or baldness. DHT levels also remained within normal clinical limits. Baseline DHT happened to be lower in the creatine group than in the placebo group, which also affected the size of the percentage change.

Later research did not reproduce a consistent androgen effect. A 2021 scientific review noted that 12 subsequent studies had examined creatine and testosterone-related outcomes. Most found no relevant increase, although not every study measured DHT directly.

Then came the 2026 trial. It measured DHT and hair together and found no adverse change.

So, can creatine cause hair loss based on the evidence we currently have? There is no convincing evidence that it does.

Understanding DHT and Androgenetic Alopecia

Why did one DHT result create so much concern in the first place?

DHT is produced from testosterone through the enzyme 5-alpha-reductase. In people genetically predisposed to androgenetic alopecia, follicles in certain areas of the scalp are particularly sensitive to androgen signalling.

Over successive hair cycles, susceptible follicles become smaller. Thick terminal hairs gradually become shorter and finer. This process is called follicular miniaturisation.

The genetic part is easy to miss.

Male pattern hair loss is not simply a case of "more DHT equals more baldness". Follicle sensitivity to normal circulating androgen levels matters greatly. Two people can therefore have similar hormone levels and very different hair patterns.

That is also why a temporary change in blood DHT would not, by itself, prove that a supplement causes creatine hair thinning.

Does Creatine Increase DHT?

One 2009 study found an increase after a high-dose loading phase. That finding drove most of the concern around creatine hair loss.

It was not consistently reproduced by later research. Most importantly, the 2026 controlled trial found no significant difference in DHT or the DHT-to-testosterone ratio after 12 weeks of 5 g creatine daily.

Current evidence therefore does not establish creatine as a reliable DHT-raising supplement.

Is It the Creatine, or Is It Genetics and Timing?

This is a surprisingly important question.

Many people begin serious gym training and supplementation in their late teens, twenties or thirties. Those are also years when genetically driven pattern hair loss can start becoming noticeable.

The timing can make the connection feel obvious:

I started creatine. A few months later my hair looked thinner. Creatine must have done it.

But two events happening around the same time do not prove that one caused the other.

Androgenetic alopecia is progressive and strongly influenced by genetics. Stress, illness, rapid weight loss, nutritional problems and thyroid disorders can cause other forms of shedding too.

If you notice creatine and hair thinning at the same time, the useful question is not simply whether you recently opened a creatine tub. Look at the pattern of loss, family history, recent illnesses, diet and other possible triggers.

Creatine Side Effects: What's Real and What Isn't?

Creatine monohydrate has been studied for decades. Some commonly repeated "side effects" have much better evidence behind them than others.

If you have kidney disease or another medical condition, supplement decisions should still be discussed with your healthcare professional.

Does Creatine Help Hair Growth?

There is no good evidence that creatine helps hair growth either.

Creatine supports rapid energy production in muscle and has established applications in strength and exercise performance. It is not a hair-growth treatment.

So the evidence currently points in neither direction: creatine has not been shown to cause hair loss, and creatine for hair should not be marketed as a way to grow it.

Creatine and Hair Loss in Women

The 2026 trial only included men. We therefore cannot claim that the study directly proves the same outcome in women.

Female pattern hair loss is also more complex than simply looking at circulating DHT. Genetics, age and hormonal factors can contribute, while diffuse shedding may have completely different causes.

There is currently no convincing evidence that creatine causes hair loss in women, but direct research specifically measuring female hair outcomes after creatine supplementation is still lacking.

That distinction is important. "No evidence of harm" and "studied extensively in women for this exact outcome" are not the same statement.

Can You Take Creatine With Finasteride or Minoxidil?

There is no established clinical evidence showing that creatine interferes with finasteride or minoxidil.

Finasteride works by inhibiting 5-alpha-reductase and reducing DHT. Minoxidil acts through a different mechanism to support hair growth.

No controlled trial has specifically tested creatine alongside these hair-loss medicines, though. If you have diagnosed androgenetic alopecia and use prescription treatment, discuss your complete supplement routine with your dermatologist rather than changing medication based on online claims about creatine.

What To Do If You're Worried About Your Hair

If creatine works well for your training but the hair-loss discussion still bothers you, keep things simple.

A daily 3–5 g of creatine monohydrate is a well-established maintenance approach. A loading phase is optional. Skipping it may also feel more comfortable if the 2009 high-dose loading study is what concerns you.

Do not repeatedly stop and restart creatine for a few days to see whether your hair changes. Hair cycles move far too slowly for that to tell you anything useful.

Instead, take photographs under similar lighting and pay attention to where thinning occurs. A dermatologist can examine the scalp and use trichoscopy when needed to distinguish pattern hair loss from other causes.

If You Stopped Creatine, Will Your Hair Grow Back?

That depends on why the hair was thinning.

If you have androgenetic alopecia, stopping creatine would not be expected to reverse the underlying genetic process because current evidence does not establish creatine as its cause.

Hair lost through temporary telogen shedding from another trigger may recover once that trigger resolves. A dermatologist can help identify which type of hair loss you actually have.

Other Causes of Hair Loss Worth Ruling Out

Before blaming a supplement, consider more established explanations.

Genetics: Androgenetic alopecia is one of the most common causes of progressive patterned thinning.

Iron status: Iron deficiency has been associated with some forms of nonscarring hair loss, particularly in women, although research is not completely uniform.

Vitamin D: Low vitamin D has been observed in several hair-loss populations, but correcting a low level does not guarantee regrowth.

Thyroid problems: Both altered thyroid function and thyroid disease can be associated with diffuse shedding.

Dieting, illness and stress: Telogen effluvium can appear months after a physiological or psychological stressor, which can make the original trigger easy to overlook.

Vitamin B12 and other nutrients: Deficiencies may be investigated when symptoms, diet or medical history suggest them, but evidence does not support taking B12 supplements indiscriminately for hair growth.

Hard water: Small studies suggest hard water can reduce hair-shaft strength. That may contribute to breakage, but this should not be confused with evidence that hard water causes androgenetic alopecia at the follicle.

Is Wellcore Creatine Safe for Your Hair?

Current evidence gives no reason to expect Wellcore creatine to cause hair loss simply because it contains creatine monohydrate.

Wellcore Pure Micronised Creatine Monohydrate contains creatine monohydrate without added sugar or fillers, and the current product directions list a 3 g scoop. Wellversed also lists Trustified-certified sachets that undergo third-party testing for purity and label accuracy.

Importantly, the 2026 hair study used 5 g/day of creatine monohydrate and found no significant adverse change in DHT or hair-follicle measures.

That does not make any supplement a treatment for hair, nor can a 12-week study guarantee what happens to every individual over a lifetime. But queries such as "does Wellcore creatine cause hair loss" or "Wellcore creatine side effects hair loss" should be answered using the evidence on creatine monohydrate, not the old assumption that creatine automatically raises DHT.

Conclusion

So, does creatine cause hair loss? Based on the best evidence available today, there is no convincing evidence that it does.

The concern began with one small 2009 study that found a temporary rise in DHT but never measured hair. In 2026, researchers finally tested the question directly. Men taking 5 g of creatine monohydrate daily for 12 weeks showed no significant difference in DHT, hair density, follicular units or hair thickness compared with placebo.

Longer studies and research in women would still be useful. For now, if your hair starts thinning while you use creatine, look beyond the supplement before assuming you have found the cause.
