Does Creatine Cause Hair Loss? The DHT Myth Explained
Key Takeaways
- The creatine-hair loss claim comes from a single 2009 study with just 20 participants.
- That study measured DHT levels — not hair loss. No participant lost any hair.
- No study since has replicated the DHT increase finding.
- Dozens of long-term creatine studies have not reported hair loss as a side effect.
- For people not genetically predisposed to hair loss, creatine poses no meaningful risk.
Where the Hair Loss Myth Comes From
The idea that creatine causes hair loss can be traced to a single study, published in 2009 in the journal Clinical Journal of Sport Medicine. Researchers at Stellenbosch University in South Africa recruited 20 male college rugby players and measured hormone levels before and after 3 weeks of creatine supplementation.
They found that DHT (dihydrotestosterone) levels increased by about 56% after a loading phase, and remained 40% above baseline during the maintenance phase. The ratio of DHT to testosterone also increased.
That is the entire scientific foundation of the creatine-hair-loss claim. Here is the critical part that tends to get lost in the retelling: not a single participant in that study lost any hair. Hair loss was never measured. Hair loss was not an outcome in the study. The researchers simply noted a hormonal change and speculated it could theoretically affect men with a genetic predisposition to androgenetic alopecia (male-pattern baldness).
Problems With the Original Study
Even setting aside the fact that no hair was measured, the original study has several significant methodological weaknesses:
- 20 participants is tiny. Hormone measurements are highly variable between individuals. A sample of 20 is far too small to draw reliable conclusions about population-level effects.
- It has never been replicated. In the 15+ years since that paper was published, no research group has published a study confirming the DHT elevation finding. Studies that have measured androgens in creatine users have generally found no significant hormonal changes.
- The DHT levels were still within normal range. Even after the reported increase, DHT levels remained within the normal physiological range for healthy young men. A within-range shift is not the same as a pathological one.
- Creatine is not androgenic. Creatine is not a steroid, a prohormone, or a testosterone booster. There is no established biological mechanism by which creatine would significantly raise DHT. The proposed pathway (creatine → increased intramuscular phosphocreatine → increased testosterone conversion) is speculative and unsupported by replication.
What the Rest of the Research Shows
Creatine is one of the most studied supplements in the history of sports nutrition. Hundreds of trials have been conducted over 30+ years, involving thousands of participants across diverse populations — men and women, young and old, athletes and non-athletes.
Hair loss has not been reported as a side effect in any of these studies. Not once. Multiple long-term trials (some lasting years) have tracked comprehensive safety markers in creatine users and found no meaningful changes in testosterone, DHT, estrogen, or other androgenic hormones compared to placebo groups.
The International Society of Sports Nutrition (ISSN), in its comprehensive position stand on creatine, explicitly notes that creatine supplementation does not cause hair loss and that the evidence base does not support the claim.
What Is DHT and Does It Cause Hair Loss?
DHT (dihydrotestosterone) is a hormone derived from testosterone via the enzyme 5-alpha reductase. In people with a genetic sensitivity to DHT — specifically a variant of the androgen receptor gene — DHT can bind to hair follicles and cause them to shrink over time, eventually leading to male-pattern baldness (androgenetic alopecia).
The key word is genetic. If you do not have the genetic predisposition for androgenetic alopecia, elevated DHT will not cause you to go bald. Hair follicles in men without this sensitivity simply do not respond to DHT in the same way.
Even if we accept the disputed finding that creatine raises DHT slightly (which remains unconfirmed), this would only theoretically matter for men who are already genetically predisposed to male-pattern baldness — and only if the DHT increase were meaningful enough to accelerate the timeline, which has never been demonstrated.
In practical terms: if your father and grandfather went bald, creatine might conceivably have some marginal effect on the timing of your hair loss — but even this is purely hypothetical with no supporting evidence. If you have no family history of hair loss, the concern is not applicable to you at all.
The Bottom Line
The creatine-hair-loss claim is one of the most persistent myths in supplement culture, and it rests on shakier ground than almost any other supplement claim. A single small study with no hair outcome data, never replicated, measured a within-range hormonal fluctuation and speculated about a possible consequence that was never observed.
If you are concerned about hair loss, the factors that actually matter are genetics, age, stress, nutritional deficiencies (particularly iron and zinc), hormonal conditions, and certain medications. Creatine is not meaningfully on that list for the vast majority of people.
Creatine monohydrate at 3–5 g per day remains one of the most evidence-backed, safest, and most effective supplements available — for muscle, strength, cognition, and healthy aging. The hair loss concern should not stop you from using it.

Frequently Asked Questions
Does creatine cause hair loss?
No. The claim comes from a single 2009 study of 20 rugby players that measured DHT levels — not hair loss. No participant in that study lost any hair. The finding has never been replicated, and no long-term creatine study has reported hair loss as a side effect. The International Society of Sports Nutrition does not list hair loss as a risk of creatine supplementation.
Does creatine raise DHT levels?
One small study from 2009 reported a DHT increase in 20 male rugby players during creatine loading. That finding has never been replicated. Multiple other studies measuring androgens in creatine users have found no significant hormonal changes. Even in the original study, DHT remained within the normal physiological range.
Should men with a family history of baldness avoid creatine?
Not necessarily. Even if you accept the unconfirmed DHT finding, male-pattern baldness (androgenetic alopecia) is primarily determined by genetics — whether your hair follicles are sensitive to DHT. A marginal, unconfirmed hormonal fluctuation from creatine has never been shown to accelerate hair loss in anyone. If you are very concerned, discuss it with your doctor — but the evidence does not support avoiding creatine on these grounds.
Is creatine a steroid? Can it affect hormones?
No. Creatine is not a steroid, prohormone, or testosterone booster. It is a naturally occurring compound found in meat and fish. Hundreds of studies spanning 30+ years have not found meaningful changes in testosterone, DHT, or other sex hormones from creatine supplementation at standard doses.
What actually causes male-pattern baldness?
Androgenetic alopecia (male-pattern baldness) is primarily genetic. Men who inherit a variant of the androgen receptor gene have hair follicles that are sensitive to DHT, which causes follicle miniaturization over time. Age, stress, nutritional deficiencies, and certain medications can also contribute. Creatine supplementation is not an established contributor.
