Does Creatine Cause Hair Loss? What Studies Show

Current research does not show that creatine causes hair loss. The study that started the concern measured a change in blood DHT, not actual hair loss. A 2025 randomized controlled trial also found no significant differences in DHT or measured hair outcomes between creatine and placebo groups.^reviewtrial

Where did the creatine and hair-loss concern begin?

A small 2009 study found an increase in blood dihydrotestosterone (DHT) after male rugby players took creatine. DHT contributes to male pattern hair loss in genetically susceptible people, so the result led to claims that creatine might cause hair loss.

The study did not measure hair density, hair thickness, or actual hair loss. It was small, and the creatine group started with lower DHT than the placebo group. Later studies have not shown a consistent increase in testosterone with creatine supplementation.^review

What did the 2025 trial measure?

In a 2025 randomized controlled trial, resistance-trained men aged 18 to 40 took either 5 g of creatine monohydrate or placebo daily for 12 weeks. Researchers measured DHT as well as hair density, follicular unit count, and hair thickness. They found no significant differences between the groups.^trial

The trial used more direct hair measurements than the earlier research. It was still limited to young men and lasted 12 weeks, so it cannot settle questions about long-term use or every population.

How do the two studies compare?

Study	What it measured	What it tells us	What it cannot tell us
2009 rugby-player study	Blood DHT	A short-term hormone change was observed	Actual shedding, density, or hair thickness
2025 randomized trial	DHT, hair density, thickness, and follicular units	No difference from placebo over 12 weeks	Long-term use or effects across sexes and ages

DHT's role in pattern hair loss does not mean that every supplement associated with a hormone change causes hair loss. The hormone finding needs to be repeatable, and studies need to show whether hair itself changes over time in susceptible people.

What if you already have pattern hair loss?

There is not enough clinical evidence to say that everyone with pattern hair loss must avoid creatine. A single 12-week trial also cannot prove long-term safety for every person.

If the uncertainty concerns you, use a simple record:

1. Photograph the hairline and crown in consistent lighting before starting.
2. Record the product, daily dose, and start date.
3. Compare monthly photographs and overall density rather than counting every shed hair.
4. Do not stop prescribed hair-loss treatment on your own.
5. If a clear change develops, bring the supplement and medication list to a dermatology appointment.

An improvement after stopping creatine would not prove causation by itself. Some shedding conditions begin weeks or months after their trigger, which makes timing difficult to interpret.

What if shedding starts while you are taking creatine?

Timing alone does not establish that creatine caused the shedding. Recent weight loss, fever or illness, severe stress, a new medicine, iron deficiency, and genetic pattern hair loss are among the other possibilities that may need consideration.

Record when the shedding began and tell your clinician about all supplements and medicines you take. Seek dermatologic evaluation for sudden, patchy, painful, scarring, or rapidly worsening hair loss.

Key takeaways

Available evidence has not shown that creatine causes hair loss. The 2025 trial found no difference in DHT or measured hair outcomes over 12 weeks. More research is still needed on long-term use and broader populations. Product prices and country-of-origin recommendations are outside this article's medical question.
