Does Creatine Cause Hair Loss? What the Evidence Actually Shows
Does creatine cause hair loss? Compare the 2009 DHT study and 2025 hair trial, their limits, and what to record if you have noticed a real change.

You start training, buy creatine and take it every day. Then you notice hair on a towel or in the shower. Your next searches practically write themselves: “does creatine cause hair loss?”, “creatine DHT”, “does creatine increase DHT?” Suddenly it feels as though you have to choose between muscles and hair.
Current evidence does not establish that standard creatine use causes hair loss. A 2025 randomised trial directly examined hair outcomes and found no significant worsening attributable to creatine over 12 weeks. That is useful evidence, not a promise about every person, dose or future year. [2]
The worry largely traces to a small 2009 study that measured hormones—not hair loss. The distinction matters more than how confidently either side of an internet argument speaks. [1]
Where the DHT claim came from
The 2009 placebo-controlled crossover study involved 20 college-aged male rugby players. The creatine phase used 25 g daily with 25 g glucose for seven days, then 5 g creatine with 25 g glucose for 14 days. The placebo supplied 50 g glucose daily initially, then 30 g. A six-week washout separated conditions. These are research protocols, not a dosing recommendation. [1]
The researchers reported higher dihydrotestosterone—DHT—and a higher DHT-to-testosterone ratio during the creatine condition; testosterone did not change significantly. They did not measure hair density, thinning or a receding hairline. A hormone finding became an internet claim about an outcome the experiment had not assessed. [1]
A later review examined the limitations of that inference. It is useful background, but predates the direct hair-outcome trial. [3]
DHT matters, but a blood number is not a hair forecast
Dihydrotestosterone is an androgen involved in androgenetic alopecia, commonly called male-pattern hair loss. Genetic susceptibility and the response of hair follicles matter; a circulating hormone measurement alone does not tell you what will happen to your hair. MedlinePlus Genetics describes the interaction of genes and androgens in this condition. [4]
Our guide to testosterone, DHT and hair loss explains that broader question. Creatine is a specific evidence question within it, not a home test for hormone levels or a reason to buy a “DHT blocker.”
What the 2025 trial actually measured
Researchers recruited 45 resistance-trained men aged 18–40. Six withdrew before the intervention; 39 began, and 38 completed the study. One placebo participant missed the final hair assessment, leaving 37 with hair-outcome data, rather than all 38 completers. [2]
For 12 weeks, the groups received either 5 g/day creatine monohydrate or 5 g/day maltodextrin placebo, without a loading phase. Testing covered DHT, total and free testosterone, and hair measures including density, follicular-unit count and cumulative thickness, with imaging focused mainly on the crown. There was no significant creatine-versus-placebo difference in change for the hormone or hair outcomes. Some hormones changed over time in both groups; that is not the same as a creatine effect. [2]
The paper reports supplement-industry relationships for some authors. That is relevant context for reading the study, alongside its methods and limitations. The result should be considered as one small, short-term trial, not the final word. [2]
Two studies, different questions
| Aspect | 2009 | 2025 |
|---|---|---|
| Participants | 20 male rugby players | 45 recruited; 38 completed; 37 had final hair data |
| Protocol | Seven-day loading, then 14-day maintenance; crossover | 12 weeks of 5 g/day creatine or maltodextrin; no loading |
| DHT | Increase reported | No significant between-group difference in change |
| Hair | Not measured | Density, follicular units and thickness assessed |
| What it cannot show | That creatine caused hair loss | Lifetime effects or every dose and susceptible subgroup |
Read the columns as different evidence, not a before-and-after trial on the same people. [1] [2]
What we know—and what remains open
| What the evidence supports | What it does not settle |
|---|---|
| The 2009 paper did not demonstrate hair loss. | Whether any individual’s shedding was caused by their supplement. |
| The direct 2025 trial found no significant hair worsening over 12 weeks. | Effects over years, higher doses or loading protocols. |
| Measured DHT did not rise because of creatine in that trial. | Local follicle androgen effects or differences by family history. |
The study did not establish family-history risk groups. Its findings should not be treated as a guarantee for someone whose relatives have male-pattern hair loss. Nor does family history prove that creatine will accelerate it. [2]
“But I really did notice more hair”
You do not have to pretend you saw nothing. The question is what the observation establishes.
Finding loose hairs after starting a product establishes timing. It does not isolate a cause. The American Academy of Dermatology notes that hair loss has many causes, including hereditary change and shedding after illness or other stressors. That makes a clear history more useful than choosing the most recent purchase as the explanation. [5]
Write down when you started creatine, when you noticed a change, other supplements or medicines, recent illness and major dietary or training changes. Do not stop a prescribed medicine to simplify your notes. A clinician can decide which details warrant investigation. Our overview of why men lose hair keeps that assessment separate from styling.
Use comparable photographs, not repeated mirror checks
A practical baseline can make a future discussion clearer. It is not a diagnostic test or the study’s specialist imaging procedure.
| View | Keep it comparable |
|---|---|
| Front | Same camera height and distance; show the hairline. |
| Left temple | Same head angle; avoid stretching or pushing the hair differently. |
| Right temple | Repeat the same position on the other side. |
| Crown | Use help or a fixed camera position rather than guessing each time. |
Use similar lighting, hair positioning and wet-or-dry condition. A different haircut or harsh overhead light can make comparisons misleading. Keep a small dated set rather than filling your phone with hourly photographs. If photographing becomes another source of distress, bring that up too.
For a separate appearance decision, haircuts for thinning hair address shape and maintenance. A haircut can change how hair looks; it does not determine why it is changing.
Should you stop creatine “just in case”?
There is no blanket instruction here to continue or stop. The evidence does not support an automatic conclusion that creatine caused the problem. Persistent observed change still deserves attention, whether you keep using it or not.
If you choose to pause, record the dates and discuss the overall picture when seeking advice. A pause and a later good hair day would not, by themselves, prove causation. Do not replace it with a collection of products that promise to protect hair without a clear diagnosis.
The doses above describe the studies. They are not a personalised supplement plan. Bring the product label and the rest of your supplement list to an appropriate consultation if you have concerns about suitability.
When not to wait for a supplement experiment
Arrange medical assessment for sudden or patchy loss, rapid visible change, or hair loss accompanied by scalp pain, inflammation or other symptoms. The AAD describes abrupt loss and scalp symptoms as possible presentations that need the cause identified. A shower count or a change in supplements cannot do that. [6]
A family history is useful context for that appointment. Hereditary hair loss can involve a receding hairline or thinning at the top of the scalp, but you should not assign yourself that diagnosis from family photographs. [5]
Is there an observed change, or mainly a fear?
What have you actually observed?
A workable next step
If the worry began with a frightening video, return to what the studies actually measured. If you have noticed a change, make a short timeline and, if useful, one comparable set of photographs. Seek assessment for persistent or concerning changes rather than running an endless supplement experiment on yourself.
Keep the rest of training understandable. A strength-training log tracks work; it cannot diagnose hair loss. Our return-to-gym guide is about rebuilding a routine. More reading sits in Weight & Fitness and Appearance.
“Creatine definitely makes you bald” outruns the evidence. So does “creatine can never affect anyone’s hair.” What we currently know does not force a simple muscles-versus-hair choice—and noticing a real change is a reason to investigate, not to argue with a stranger online.
