Does Creatine Cause Hair Loss? DHT, Baldness & What Research Shows
Current human evidence does not show that creatine monohydrate causes hair loss or baldness.
The concern largely comes from a small 2009 study in male rugby players that reported an increase in dihydrotestosterone, or DHT, after creatine supplementation. DHT is relevant because androgen signaling plays an important role in androgenetic alopecia, commonly called male-pattern or female-pattern hair loss.
However, the 2009 study measured hormones. It did not measure hair loss, hair shedding, follicle miniaturization, hair density or baldness.
In 2025, researchers published the first randomized controlled trial designed to directly investigate creatine supplementation and hair-follicle health. After 12 weeks, the researchers found no significant differences between creatine and placebo in DHT or the hair-related outcomes they measured.
That newer evidence is reassuring, but the question still deserves nuance. The 2025 trial used 5 g/day without a loading phase, lasted 12 weeks and studied men. It therefore cannot answer every possible question about longer durations, high-dose loading protocols or every subgroup.
This guide examines creatine and hair loss, creatine and DHT, male-pattern baldness, hair shedding, genetic susceptibility, creatine loading, hair-follicle health and the 2009 versus 2025 research without treating either a biological theory or a single study as more conclusive than it is.

Quick answer: Does creatine cause hair loss?
Current evidence does not establish creatine as a cause of hair loss.
The concern began largely with a 2009 study that found higher DHT after creatine supplementation in male rugby players. That study did not measure hair.
A 2025 randomized controlled trial directly measured DHT and several hair-health outcomes after 12 weeks of 5 g/day creatine monohydrate and found no significant differences compared with placebo.
The evidence therefore does not support describing hair loss as a proven creatine side effect. At the same time, the 2025 trial did not test every possible loading protocol, duration or population, so absolute claims that the question is permanently settled would also go beyond the data.
Why Do People Think Creatine Causes Hair Loss?
The modern creatine-and-hair-loss debate can be traced largely to one study published in 2009.
Researchers studying college-aged rugby players observed changes in dihydrotestosterone (DHT) during a three-week creatine protocol.
Because DHT is involved in androgenetic alopecia in genetically susceptible scalp follicles, the result was interpreted online as evidence that creatine might cause baldness.
But several steps separate those two statements:
creatine → DHT change → follicle response → hair miniaturization → visible hair loss
The 2009 study investigated only part of that chain.
It measured serum testosterone and DHT. It did not measure what happened to the participants' hair follicles.
What Is DHT?
Dihydrotestosterone, or DHT, is an androgen produced from testosterone through the action of the enzyme 5-alpha-reductase.
DHT binds to androgen receptors and has important physiological functions.
It is also relevant to androgenetic alopecia because androgen signaling within genetically susceptible scalp follicles can contribute to progressive follicular miniaturization.
This is why the question:
“Does creatine increase DHT?”
became closely connected to:
“Does creatine cause hair loss?”
But these are still two different scientific questions.
How Does DHT Relate to Male-Pattern Hair Loss?
The most common patterned form of hair loss is androgenetic alopecia.
Modern dermatology research describes androgenetic alopecia as a progressive miniaturization of susceptible hair follicles.
In men, increased androgen signaling within genetically susceptible follicles is considered an important mechanism.
A 2025 review in Nature Reviews Disease Primers also highlighted the strong genetic component of androgenetic alopecia, noting that genome-wide studies have identified hundreds of associated genomic loci.
See: 2025 Nature Reviews Disease Primers — Androgenetic Alopecia .
This matters because hair loss cannot be reduced to:
higher blood DHT = automatic baldness.
Follicle susceptibility, genetics, androgen-receptor signaling, age and other biological factors all contribute to the condition.
Higher DHT Is Not the Same as Proven Hair Loss
This is the most important distinction in the creatine hair-loss debate.
A hormonal change may provide a plausible mechanism worth investigating.
But showing that a hormone changed does not automatically show:
- that scalp hair follicles were damaged
- that follicles became smaller
- that hair density decreased
- that hair shedding increased
- that visible baldness progressed
Those are separate outcomes that have to be measured.
That distinction explains why the 2025 trial was important: it investigated hair-related outcomes directly rather than inferring them from a hormone measurement alone.
What Did the 2009 Creatine and DHT Study Actually Find?
The study most often cited in discussions of creatine and baldness was published in the Clinical Journal of Sport Medicine in 2009.
Twenty college-aged male rugby players participated in the research.
The creatine protocol included:
- 25 g/day for 7 days during a loading phase
- 5 g/day for the following 14 days
Researchers measured serum testosterone, serum DHT and the DHT-to-testosterone ratio.
DHT increased by approximately 56% from baseline after the seven-day loading period and remained approximately 40% above baseline after the maintenance period.
Total testosterone did not significantly increase.
Read the original study: Three Weeks of Creatine Monohydrate Supplementation Affects Dihydrotestosterone-to-Testosterone Ratio in College-Aged Rugby Players .
Did the 2009 Study Measure Hair Loss?
No.
The study did not measure:
- hair density
- hair shedding
- follicle count
- follicle miniaturization
- hair thickness
- receding hairlines
- baldness progression
That limitation is fundamental.
The study provided a reason to investigate a potential hormonal pathway. It did not demonstrate that creatine made anyone lose their hair.
What Other Limitations Did the 2009 Study Have?
The study was small, and the later 2021 evidence review highlighted several details that complicate interpretation.
Baseline DHT was lower in the creatine group than in the placebo condition, and the reported DHT concentrations remained within normal clinical limits.
The review also noted that the DHT result had not been replicated in the creatine literature available at that time.
See: Common Questions and Misconceptions About Creatine Supplementation .
What Did the 2025 Creatine Hair-Loss Study Find?
In 2025, researchers published the first randomized controlled trial designed specifically to assess creatine supplementation and hair-follicle health.
The trial recruited 45 resistance-trained men aged 18–40. Thirty-eight completed the study.
Participants received either:
- 5 g/day creatine monohydrate
- or a placebo
for 12 weeks.
Researchers assessed androgen concentrations and hair-related parameters.
The study found no significant creatine-versus-placebo differences in:
- DHT
- DHT-to-testosterone ratio
- hair density
- follicular unit count
- cumulative hair thickness
- other measured hair-growth parameters
See: Does Creatine Cause Hair Loss? A 12-Week Randomized Controlled Trial .
This is much more directly relevant to the hair-loss question than a study measuring DHT alone because the researchers actually evaluated hair-follicle health.
What Are the Limitations of the 2025 Study?
The 2025 trial provides reassuring direct evidence, but its boundaries should still be respected.
It studied:
- men rather than both sexes
- resistance-trained participants
- 5 g/day
- 12 weeks of supplementation
- a relatively modest number of participants
It did not use the 25 g/day loading protocol from the original 2009 rugby-player study.
It also cannot tell us what would happen under every possible dose, duration, genetic background or pre-existing hair condition.
Therefore, the strongest evidence-based statement is:
Standard-dose creatine monohydrate did not worsen the measured hair-health outcomes during this 12-week randomized controlled trial.
That is stronger and more accurate than either saying creatine definitely causes baldness or claiming that no possible unanswered questions remain.
2009 vs 2025 Creatine Hair Research
| Feature | 2009 study | 2025 study |
|---|---|---|
| Main question | Effect on androgens | Effect on androgens and hair-follicle health |
| Participants | College-aged male rugby players | Resistance-trained men aged 18–40 |
| Creatine protocol | 25 g/day loading for 7 days, then 5 g/day | 5 g/day without loading |
| Duration | 3 weeks | 12 weeks |
| DHT result | Increased during the creatine condition | No significant creatine-vs-placebo difference |
| Hair measured? | No | Yes |
| Hair outcome | Not assessed | No significant adverse difference |
Does Creatine Increase DHT?
Current evidence does not support saying that creatine consistently increases DHT.
One small 2009 study reported an increase.
The 2025 randomized trial using 5 g/day did not find a significant creatine-versus-placebo difference in DHT.
The correct conclusion is therefore not:
“Creatine definitely raises DHT.”
Nor is it necessary to pretend that the 2009 result never existed.
The evidence shows one older positive finding that was not reproduced in the newer direct hair-health trial.
Does Creatine Damage Hair Follicles?
No convincing human evidence currently shows that creatine damages hair follicles.
This question can now be answered more directly because the 2025 trial examined actual follicle-related measurements rather than relying solely on hormones.
Researchers found no significant adverse difference in hair density, follicular unit count or cumulative hair thickness after 12 weeks of creatine.
That does not prove every possible lifetime exposure has been studied, but it is direct evidence against the claim that ordinary creatine use obviously damages follicles over the period investigated.
Does Creatine Cause Male-Pattern Baldness?
Creatine has not been shown to cause androgenetic alopecia.
Male-pattern hair loss is strongly influenced by genetics and androgen signaling within susceptible scalp follicles.
Creatine is not recognized as an established cause of androgenetic alopecia.
The existence of a theoretical DHT pathway does not establish that taking creatine initiates or accelerates male-pattern baldness.
Creatine Hair Shedding vs Androgenetic Alopecia
Hair shedding and androgenetic alopecia should not be treated as interchangeable.
Hair shedding describes the observation that hairs are being lost. It does not identify the cause.
Androgenetic alopecia is a patterned condition characterized by progressive miniaturization of susceptible follicles.
Other forms of hair loss can involve different mechanisms entirely.
Therefore, noticing more hair in a shower or on a pillow while taking creatine does not by itself establish that creatine caused androgenetic alopecia.
Does Family History of Baldness Change Creatine Risk?
Genetics strongly affect androgenetic alopecia.
However:
current studies have not established that creatine specifically accelerates hair loss in people with a family history of pattern baldness.
A family history can indicate greater underlying susceptibility to androgenetic alopecia itself.
That is different from having evidence that creatine uniquely increases risk within that subgroup.
This distinction matters because biological plausibility should not be presented as demonstrated clinical risk.
Does a Creatine Loading Phase Increase Hair-Loss Risk?
No study has demonstrated that a creatine loading phase causes hair loss.
However, this remains one of the more interesting unresolved details in the research.
The original 2009 DHT signal occurred during a protocol beginning with 25 g/day for seven days.
The 2025 direct hair-health trial instead used 5 g/day without a loading phase.
Therefore, the newer study does not directly reproduce the exact high-dose protocol that produced the original DHT finding.
That does not mean loading causes baldness.
It means direct hair outcomes during a comparable loading protocol remain less studied than standard daily supplementation.
For a complete explanation of loading, gradual supplementation and muscle-creatine saturation, see: Creatine Loading vs Maintenance: Is a Loading Phase Necessary? .
Does 5 g of Creatine Cause Hair Loss?
The strongest direct human evidence currently available does not show that 5 g/day creatine monohydrate causes measurable hair loss over 12 weeks.
That was the amount used in the 2025 randomized controlled trial, which found no significant adverse difference in DHT or the measured hair-growth parameters compared with placebo.
This should still be interpreted within the study duration and population rather than converted into a claim about every possible person or duration.
Does Creatine Monohydrate Cause Hair Loss?
Creatine monohydrate has not been shown to cause hair loss.
Creatine monohydrate is also the form used in both the influential 2009 DHT study and the newer direct hair-health research.
The conflicting hormone findings between studies reinforce why conclusions should be based on the full evidence rather than one isolated result.
Can Creatine Make Existing Hair Loss Worse?
There is currently insufficient direct evidence showing that creatine accelerates pre-existing androgenetic alopecia.
This has not been adequately tested as a dedicated subgroup question.
Therefore, it would be inaccurate to claim either that creatine definitely worsens existing pattern hair loss or that this specific scenario has been comprehensively ruled out.
Existing hair loss should be understood according to its actual cause rather than automatically attributed to creatine.
Is Creatine Hair Loss Permanent?
This question assumes something that has not been established: that creatine causes a specific form of hair loss in the first place.
Because a creatine-induced hair-loss condition has not been demonstrated, research cannot provide a reliable timeline for whether such hair loss would be temporary or permanent.
If hair loss is actually caused by another condition such as androgenetic alopecia, its course depends on that underlying condition rather than on whether creatine is continued.
Does Hair Grow Back After Stopping Creatine?
There is no evidence-based “creatine hair regrowth timeline.”
Creatine-induced hair loss has not been established, so studies cannot reliably tell us how quickly hair supposedly returns after discontinuation.
Hair recovery depends on the true cause of the shedding or thinning.
Stopping one supplement would not necessarily reverse a separate underlying hair-loss condition.
Does Stopping Creatine Stop Hair Loss?
Not necessarily.
If creatine was not the cause of the hair loss, stopping creatine would not address the underlying mechanism.
This is why timing alone:
“I started creatine and then noticed shedding”
does not establish causation.
Does Creatine Cause Hair Loss in Women?
There is currently no convincing evidence establishing creatine as a cause of hair loss in women.
However, the 2025 randomized trial that directly measured hair outcomes was conducted in men.
Its results therefore should not be automatically treated as a dedicated clinical trial of female-pattern hair loss.
Modern reviews also emphasize that the biological basis of pattern hair loss in women is not identical in every respect to androgenetic alopecia in men.
The most accurate answer is therefore:
evidence does not currently identify creatine as a cause of female hair loss, but direct creatine-specific hair research in women remains limited.
Is “Creatine Alopecia” a Real Diagnosis?
No. “Creatine alopecia” is not a recognized medical diagnosis.
Alopecia simply means hair loss.
Different hair-loss disorders have different mechanisms. Examples include:
- androgenetic alopecia
- alopecia areata
- telogen effluvium
- scarring alopecias
Treating every form of hair loss noticed during creatine use as “creatine alopecia” obscures rather than clarifies the actual cause.
Does Creatine Help Hair Growth?
No convincing evidence shows that creatine improves hair growth, hair density or follicle health.
Creatine's established role is primarily related to cellular energy availability and sports-performance applications.
Evidence against creatine causing hair loss should not be misinterpreted as evidence that creatine is a hair-growth treatment.
What Should Be Considered If Hair Loss Starts While Taking Creatine?
A new symptom occurring after a supplement is started does not automatically mean the supplement caused it.
Hair shedding and thinning can have many potential explanations, including:
- androgenetic alopecia
- recent illness or major physiological stress
- significant dietary restriction or weight change
- nutrient deficiencies
- thyroid or hormonal conditions
- medications
- autoimmune hair-loss disorders
- other dermatological conditions
Sudden, persistent, patchy or otherwise unexplained hair loss deserves appropriate medical evaluation rather than being automatically assigned to a sports supplement.
Creatine Hair-Loss Myths vs Evidence
| Claim | What current evidence supports |
|---|---|
| “Creatine is proven to cause hair loss.” | No. Direct human evidence has not established creatine as a cause of hair loss. |
| “The 2009 study showed people went bald.” | No. It measured DHT and testosterone, not hair loss. |
| “Creatine always increases DHT.” | One older trial found an increase; the 2025 randomized trial did not find a significant creatine-vs-placebo DHT difference. |
| “Higher blood DHT automatically means baldness.” | Androgenetic alopecia depends strongly on genetically susceptible follicles and androgen signaling, not one serum measurement alone. |
| “The 2025 study proved creatine can never affect hair.” | It provides reassuring direct evidence over 12 weeks at 5 g/day, but it does not test every dose, duration or population. |
| “Creatine loading is proven to cause baldness.” | No study has demonstrated hair loss caused by creatine loading. |
| “Stopping creatine will definitely regrow lost hair.” | Creatine-induced hair loss has not been established, so no evidence-based reversal timeline exists. |

Frequently Asked Questions About Creatine and Hair Loss
Does creatine cause hair loss?
Current human evidence does not establish creatine as a cause of hair loss. A 2025 randomized trial found no significant difference in DHT or measured hair-health parameters between creatine and placebo after 12 weeks.
Does creatine increase DHT?
One small 2009 study found higher DHT during a creatine protocol, while a 2025 randomized trial found no significant creatine-vs-placebo difference in DHT. The evidence does not support saying creatine consistently increases DHT.
What did the 2009 creatine DHT study find?
Male rugby players used 25 g/day for seven days followed by 5 g/day. DHT increased from baseline during the creatine condition. The study measured hormones, not hair loss.
Did the 2009 creatine study measure hair loss?
No. It did not measure hair density, shedding, follicle health, hair thickness or baldness progression.
What did the 2025 creatine hair study find?
Men taking 5 g/day of creatine monohydrate for 12 weeks showed no significant adverse difference from placebo in DHT or measured hair-growth parameters, including hair density and cumulative thickness.
Did creatine reduce hair density in the 2025 study?
No significant creatine-versus-placebo reduction in hair density was found.
Does creatine damage hair follicles?
Current human evidence does not show that creatine damages hair follicles. The 2025 trial directly assessed follicle-related outcomes and found no significant adverse difference from placebo.
Does creatine cause baldness?
Creatine has not been demonstrated to cause baldness or androgenetic alopecia.
Does creatine cause male-pattern baldness?
No study has established creatine as a cause of male-pattern baldness. Androgenetic alopecia is strongly influenced by genetics and androgen signaling in susceptible follicles.
Does creatine cause hair shedding?
Controlled evidence has not demonstrated increased hair shedding caused by creatine. New shedding can have many potential causes and should not automatically be attributed to supplementation.
Can creatine make existing hair loss worse?
Direct evidence showing that creatine accelerates existing androgenetic alopecia is lacking. This specific subgroup question remains insufficiently studied.
Does family history of baldness make creatine more risky?
Family history is relevant to the underlying risk of androgenetic alopecia, but studies have not established a creatine-specific increased risk among people with a family history of pattern hair loss.
Does creatine loading cause hair loss?
No study has demonstrated that loading causes hair loss. The original 2009 DHT finding occurred during a loading protocol, but hair was not measured.
Does creatine loading increase DHT?
The 2009 study reported a DHT increase during a 25 g/day loading protocol. Direct hair outcomes under the same loading protocol have not been adequately studied.
Does 5 g of creatine cause hair loss?
The 2025 randomized trial used 5 g/day for 12 weeks and found no significant adverse difference in the measured hair-health outcomes compared with placebo.
Does creatine monohydrate cause hair loss?
Current evidence does not establish creatine monohydrate as a cause of hair loss.
Is creatine hair loss permanent?
A distinct creatine-induced hair-loss condition has not been established, so research cannot provide an evidence-based permanent-versus-temporary timeline.
Does hair grow back after stopping creatine?
There is no established creatine-specific regrowth timeline because creatine has not been proven to cause hair loss. Hair recovery depends on the true underlying cause.
Does stopping creatine stop hair loss?
Not necessarily. If another condition is causing the hair loss, stopping creatine would not address that cause.
Does creatine cause hair loss in women?
There is no convincing evidence establishing creatine as a cause of female hair loss, but direct creatine-specific hair research in women remains limited.
Is creatine alopecia a real medical diagnosis?
No. “Creatine alopecia” is not a recognized diagnosis. Alopecia is a broad term covering multiple different hair-loss conditions.
Does creatine help hair growth?
No convincing evidence shows that creatine increases hair growth, density or thickness.
Should you stop creatine if you notice hair shedding?
Hair shedding beginning during creatine use does not prove creatine caused it. Sudden, persistent, patchy or otherwise unexplained hair loss should be assessed according to its actual pattern and possible causes rather than automatically being attributed to one supplement.
Conclusion: Does Creatine Really Cause Hair Loss?
Current human evidence does not show that creatine monohydrate causes hair loss.
The concern originated largely from a 2009 study in male rugby players that found an increase in serum DHT after creatine supplementation.
That result was worth investigating because DHT and androgen signaling are relevant to androgenetic alopecia.
But the 2009 study did not actually measure hair loss.
In 2025, the first randomized controlled trial directly assessing hair-follicle health during creatine supplementation found no significant adverse difference between creatine and placebo in DHT, hair density, follicular units, cumulative hair thickness or the other measured hair outcomes.
That makes the current evidence substantially more reassuring than it was when the creatine-hair-loss theory first became popular.
At the same time, good evidence interpretation requires acknowledging what has not yet been tested.
The 2025 trial used 5 g/day rather than the high-dose loading protocol from the original 2009 study, lasted 12 weeks and involved men. It therefore does not answer every possible question about dose, duration or population.
The central distinction remains:
a possible change in a hormone associated with hair biology is not the same thing as demonstrating hair-follicle damage or baldness.
Based on the evidence available today, hair loss should not be presented as an established side effect of creatine monohydrate.
