Creatine is one of the most studied supplements in sports nutrition, and one of the most popular in any gym. It is also the supplement that young men ask about most often in a hair transplant consultation. Many of them have read online that creatine raises DHT, the hormone behind male pattern baldness, and some have already stopped taking it the moment they noticed a few extra hairs in the shower.
The worry is understandable: the men who use creatine are often in exactly the age group where pattern hair loss first appears. But a supplement that happens to be taken at the same age as hair loss starts is not the same as a supplement that causes it. This article looks at where the concern came from, what the research has found since, and how creatine fits into the bigger picture of what actually decides whether you lose your hair.
Where the creatine and hair loss worry comes from?
Almost the entire concern goes back to one small study. In 2009, researchers in South Africa gave creatine to 20 college rugby players for three weeks and measured their hormones. Testosterone did not change, but DHT rose by 56% after a week of high-dose loading (25 g a day) and stayed 40% above baseline during the following two weeks on a normal 5 g dose.
Because DHT is the hormone that shrinks genetically sensitive hair follicles, the link to baldness seemed obvious, and it spread quickly through forums and social media. What usually gets left out is what the study did not do:
- It never looked at hair. No hair counts, no photos, no scalp examination. It measured a hormone in the blood, not hair loss.
- It was very small and very short. Twenty players, three weeks.
- A blood hormone is not a hair outcome. Pattern baldness depends on how sensitive your follicles are to DHT, not only on how much DHT is in your blood.
- It has not been confirmed. No later study has reproduced the same DHT increase, and the first trial to measure hair directly found none (see below).
The study raised a reasonable question. It did not answer it.
What the newer research shows
Reviews of creatine safety
Creatine has been studied in more than 500 peer-reviewed publications. When an international group of sports nutrition researchers reviewed the most common questions and misconceptions about creatine in 2021, hair loss was one of the twelve questions they addressed. Their conclusion was that the evidence does not show creatine increases total testosterone, free testosterone, DHT or hair loss, and that the 2009 finding remained isolated.
The first trial that actually measured hair
In 2025, a 12-week randomised controlled trial finally looked at the scalp, not just the blood. Forty-five resistance-trained men aged 18 to 40 took either 5 g of creatine monohydrate or a placebo every day; 38 completed the study.
| What was measured | Creatine vs placebo after 12 weeks |
|---|---|
| DHT level | No difference |
| DHT-to-testosterone ratio | No difference |
| Hair density (FotoFinder) | No difference |
| Follicular unit count | No difference |
| Cumulative hair thickness | No difference |
| Trichogram (hair root analysis) | No difference |
The authors described it as strong evidence against the claim that creatine contributes to hair loss.
What the evidence still cannot tell us
Twelve weeks is short compared with the years over which pattern baldness develops, and the trial included only healthy young men. There is still no long-term study in men who are already losing their hair. That gap is the honest limit of the evidence, and it is why the advice later in this article is cautious rather than dismissive.
Why DHT is only part of the story?
Your genes decide how your follicles react
Every man has DHT, made from testosterone by an enzyme called 5-alpha reductase. Most men never go bald. What separates them is not the amount of DHT but how sensitive the follicles at the hairline, temples and crown are to it, and that sensitivity is inherited. The follicles at the back and sides of the scalp are resistant, which is why they are used as the donor area in a hair transplant and why they keep growing for life after they are moved.
This is why the same supplement, diet or training programme can coincide with hair loss in one man and leave his gym partner’s hair untouched. If your hair is genetically programmed to thin, it will thin with or without creatine. If it is not, there is no evidence creatine will start the process.
Who should be more careful
The evidence does not support stopping creatine to protect your hair. Still, in consultation I give a more cautious answer to men in a few situations:
- Your hair loss is active and moving fast. When shedding is already high, I prefer to change one thing at a time so we can see what actually helps. Treating the hair loss itself comes first.
- You have a strong family history of early baldness and are in your late teens or twenties. You are in the group most likely to lose hair anyway, so it is worth tracking your hairline with photos whether or not you take creatine.
- You are taking other products alongside creatine. Pre-workout blends, “testosterone boosters” and especially anabolic steroids or SARMs are a very different matter: these do act on androgen levels, and they are a far more likely culprit than creatine.
Can you take creatine with finasteride or minoxidil?
There is no known interaction between creatine and finasteride or minoxidil. Many men who train regularly take creatine alongside hair loss medication. Finasteride works by reducing the conversion of testosterone to DHT, so if anything, it addresses the exact mechanism people worry about. Medication should always be prescribed and followed up by a doctor.
If your hair is thinning, look beyond the supplement
Common causes that get blamed on creatine
When a young man starts training, changes his diet and begins taking supplements in the same few months, creatine is often the first thing he suspects. In my experience, the cause is usually one of these:
- Male pattern baldness starting on its own schedule. The late teens and twenties are exactly when it first shows, gym or no gym.
- Shedding after a crash diet or rapid weight loss. An aggressive cut can trigger temporary shedding two to three months later.
- Low iron stores or other deficiencies, particularly with very restrictive diets.
- Anabolic steroids, SARMs or “testosterone boosters”, which raise androgen levels and can accelerate pattern hair loss in men who are prone to it.
- Stress and poor sleep, which can tip the scalp into a period of heavier shedding.
Why evaluation comes before any decision
The right response to thinning hair is not to stop a supplement and hope, but to find out what is really happening. A short consultation with trichoscopy can show whether the hairs at your hairline and crown are miniaturising, which points to pattern baldness, or whether the whole scalp is shedding evenly, which points to a temporary trigger. Blood tests fill in the rest when needed.
If pattern baldness is confirmed, the hair you still have is worth protecting early. Alongside prescription medication, in-clinic options such as PRP hair treatment and hair mesotherapy can support the scalp.
Creatine and the gym around a hair transplant
For patients who come to Istanbul for a hair transplant, creatine is not a reason to delay surgery. The more important question is training. After surgery, light exercise can usually start after about 15 days, and full training, including heavy lifting, after one month. Sweating heavily and straining in the first days put the new grafts at risk, so the timing of your return to the gym matters far more than your supplement shelf. Once you are back in training, creatine can be resumed as before; the transplanted follicles come from the DHT-resistant donor area and keep that resistance for life.
Dr. Erdoğan’s Verdict: Keep the Creatine, Watch the Hairline
The fear about creatine rests on one small, short study that measured a blood hormone and never looked at hair. The first trial that did look at hair found no difference in DHT, density or thickness. On current evidence, creatine is not what decides whether you go bald; your genes are.
That does not mean thinning hair should be ignored. If you notice your hairline or crown changing, the useful step is not to empty your supplement cabinet but to find out what is actually happening, as early as possible, while there is still plenty of hair to protect.
Training Hard and Thinning Anyway? Find Out What Is Really Going On
If your hairline is moving or your crown is thinning despite everything you do right in the gym, a surgeon’s assessment will tell you whether it is pattern baldness, a temporary shed or something else. Send photos of your hairline, crown and the back of your head, and you will get a clear answer on whether medication, a scalp treatment or a transplant makes sense for you. If restoration is the next step, see how a hair transplant in Turkey fits around your training schedule, what a hair transplant in Turkey costs, and what the hair transplant package includes from arrival to aftercare.
Frequently asked questions
Does creatine increase DHT?
One 2009 study of 20 rugby players found a rise in blood DHT after three weeks, but it has not been reproduced. A 2025 randomised trial found no difference in DHT or in the DHT-to-testosterone ratio between creatine and placebo after 12 weeks.
Does creatine make you bald?
There is no evidence that it does. The only trial to measure hair directly found no change in hair density, follicle count or hair thickness. Baldness is driven by inherited sensitivity to DHT, not by creatine.
Should I stop creatine if my hair is thinning?
Stopping creatine is unlikely to change the course of pattern hair loss. It is more useful to have the thinning evaluated so the real cause can be treated. If you prefer to pause it while you find out, that is a reasonable personal choice, but it should not replace a diagnosis.
Can I take creatine with finasteride?
There is no known interaction. Finasteride lowers the conversion of testosterone to DHT, which is the mechanism people worry about with creatine. Finasteride should be prescribed and monitored by a doctor.
Can I take creatine after a hair transplant?
Yes. What matters after surgery is when you return to training: light exercise after about 15 days and full workouts after one month. Creatine can be resumed with your normal routine.
