Does Creatine Cause Hair Loss?

Current evidence does not show that creatine causes hair loss. A 2025 randomized controlled trial found that 12 weeks of creatine changed neither DHT nor testosterone, and it did not reduce hair density or follicle count. The whole worry traces back to one small 2009 study that measured a hormone shift, not actual shedding.

The short answer

Creatine is a supplement that helps muscles produce energy during hard training, and the fear that it thins hair comes from a single 2009 study of college rugby players. That study reported a rise in dihydrotestosterone (DHT), the hormone that shrinks follicles in people genetically prone to male pattern baldness. It never measured anyone’s hair.

In 2025, researchers ran the first trial built to answer the question directly. Over 12 weeks, resistance-trained men aged 18 to 40 took 5 grams of creatine a day. The study found no meaningful change in DHT, free or total testosterone, hair density, or follicle counts compared with placebo. If you carry the genes for pattern hair loss, creatine is very unlikely to be what tips you over the edge. Your position on the Norwood scale is driven by genetics and follicle sensitivity to DHT, not by a scoop of powder in your protein shake.

Where did the creatine hair loss myth come from?

The myth started with one 2009 study of 20 rugby players. During a creatine loading phase (a high short-term dose of around 25 grams a day), researchers measured a jump in DHT of about 50 percent, though the level stayed inside the normal physiological range. The players’ testosterone did not change, and crucially, no one looked at their scalps or counted a single hair.

From there, the internet did what the internet does. A hormone marker that moved on paper became “creatine makes you bald” in forums and comment sections. For over a decade that single unreplicated result was the entire basis for the scare. No follow-up study reproduced the DHT spike at standard doses.

Does creatine raise DHT?

At normal doses, the current evidence says no. The 2009 rugby paper used a heavy loading protocol and reported a temporary DHT bump, but multiple later trials failed to repeat it. The 2025 controlled trial used 5 grams a day, the dose almost everyone actually takes, and saw no change in DHT at all.

This distinction matters because DHT is the real driver of pattern hair loss. In people with the inherited trait, DHT gradually miniaturizes follicles along the hairline and crown until they stop producing visible hair. A supplement that does not move your DHT is not going to accelerate that process.

What did the 2025 creatine study find?

The 2025 randomized controlled trial was the first to look at hair follicles directly after creatine use, not just blood hormones. Here is how the evidence stacks up.

Measure	2009 rugby study	2025 controlled trial
Dose	~25 g/day loading	5 g/day for 12 weeks
DHT change	Rose ~50% (stayed normal)	No significant change
Testosterone	No change	No change
Hair measured?	No	Yes (density and follicle count)
Effect on hair	Not assessed	No loss vs placebo

The trial was modest in size, around 38 men over 12 weeks, so it cannot rule out a tiny effect over many years. What it can say is that at everyday doses, creatine did not raise DHT and did not shrink hair in the people tested.

Should you stop taking creatine if you are worried about hair loss?

For most people, there is no evidence-based reason to stop. Creatine is one of the most studied sports supplements there is, and the direct research on hair points away from harm. If you are already noticing a receding hairline or thinning crown, the more useful question is whether pattern hair loss is the cause, since that is treatable and creatine is not the trigger.

If it gives you peace of mind, you can skip the loading phase and take a steady 3 to 5 grams a day, which is all that is needed for the muscle benefits anyway. A dermatologist or hair restoration specialist can check your scalp and tell you what is actually happening. Taking the free Norwood scale quiz is a quick first step to see roughly where you stand.

What actually causes pattern hair loss?

Pattern hair loss is genetic and hormonal, not a side effect of the gym. It happens when inherited follicles are sensitive to DHT, which slowly miniaturizes them over years. The common causes of hair loss in men center on this genetic sensitivity, with stress, illness, and nutrition acting as secondary factors that can worsen shedding but rarely cause baldness on their own.

If your hair is thinning in the classic M-shaped hairline or crown pattern, proven treatments like finasteride and minoxidil slow the process, and a hair transplant can restore density once loss has stabilized. Blaming the creatine tub only delays the step that helps.

Is creatine safe?

Creatine monohydrate has a strong safety record at standard doses for healthy adults, and the hair concern is not supported by direct evidence. As with any supplement, people with kidney disease or other medical conditions should check with a doctor first. This article is educational and not a substitute for personal medical advice.

Frequently asked questions

Will creatine make me go bald faster if baldness runs in my family? There is no direct evidence that it does. The 2025 controlled trial found no change in DHT or hair count at 5 grams a day. Your genetic risk of pattern hair loss exists with or without creatine, so the smarter move is to treat the pattern loss early rather than avoid the supplement.

Does creatine loading (20 to 25 grams a day) affect hair? The only study to report a DHT rise used a loading dose, but it never measured hair and no trial has reproduced that finding. If you are cautious, you can skip loading entirely and take a maintenance dose of 3 to 5 grams a day, which delivers the same long-term benefits.

If my hair is already thinning, is creatine to blame? Almost certainly not. Thinning at the hairline or crown is usually pattern hair loss, which is genetic and driven by DHT. A dermatologist or hair restoration surgeon can confirm the cause and lay out treatment options that work.

Worried the thinning you see is more than a supplement scare? A specialist can tell you exactly what is going on and what to do about it. Request a free, no obligation consultation with a Dallas-Fort Worth hair restoration specialist to get a clear read on your hairline and a plan built around it.
