Does creatine cause hair loss? One study started it. Here's the full picture.
Short answer: there is no direct evidence that creatine causes hair loss. The fear traces back to a single small 2009 study where creatine raised DHT, a hormone linked to male pattern baldness - but hair was never measured. More recent controlled research has not found meaningful DHT or hair changes. Creatine also doesn't meaningfully change testosterone or libido.
Where the claim comes from
In 2009, a study of 20 college rugby players (van der Merwe et al.) found that after a week of creatine loading, levels of dihydrotestosterone (DHT) rose by about 56%, and stayed around 40% above baseline during maintenance. DHT is the hormone that shrinks genetically susceptible hair follicles in male pattern baldness. The internet connected the dots: creatine raises DHT, DHT causes baldness, so creatine causes baldness. But the study didn't measure hair at all, and its DHT values stayed within the normal range.
What newer research shows
That result has never been cleanly replicated. Other studies on creatine and hormones found no significant changes in testosterone or DHT. A 2025 randomized controlled trial specifically looking at creatine and hair (12 weeks, resistance-trained men) found no significant difference in DHT, the DHT-to-testosterone ratio, or hair follicle measurements versus placebo. Reviews by sports nutrition researchers conclude the current evidence does not support creatine as a cause of hair loss.
So why do some people swear it did?
Male pattern hair loss affects a large share of men and often starts in the 20s and 30s - exactly when many start lifting and supplementing. Hair shedding also has natural cycles and is triggered by stress, crash dieting and illness. When hair loss starts after creatine, it's easy to blame the most recent change. Correlation in one person's timeline isn't causation.
Who might still want to be cautious
If you have a strong family history of early baldness and are already losing hair, it's reasonable to talk to a dermatologist. Some men choose to skip creatine out of caution, or pair it with proven hair-loss treatments. That's a personal risk decision, not a proven effect.
Does creatine affect testosterone or libido?
Most studies show no meaningful change in total testosterone. There's no evidence creatine lowers libido or harms erections. Indirectly, better training performance and body composition can support sexual health. What does hurt libido in lifters is under-recovery: too much volume, too little sleep and aggressive dieting.
Is creatine safe?
Creatine monohydrate is one of the most studied supplements in sports nutrition, with a strong safety record at typical doses (3 to 5 g/day) in healthy people. People with kidney disease should talk to a doctor first.
WHAT YOU GET
Built for signal, not noise.
One study, no hair measured
The 2009 rugby study measured DHT, never hair loss.
Newer trial: no effect found
A 2025 RCT found no significant DHT or hair follicle changes vs placebo.
No libido hit
Creatine doesn't meaningfully change testosterone. Over-training and poor sleep do.

QUESTIONS
What people ask before signing up.
Does creatine cause hair loss?
There's no direct evidence. The concern comes from one small 2009 study where creatine raised DHT, but hair loss wasn't measured and later research hasn't confirmed an effect.
Does creatine increase DHT?
One study found a rise in DHT within the normal range. Several other studies, including a 2025 randomized trial, found no significant change.
Does creatine lower testosterone?
No. Most studies show no meaningful change in testosterone with creatine supplementation.
Should I stop creatine if I'm balding?
Hair loss usually has genetic causes unrelated to creatine. If you're concerned, see a dermatologist; stopping creatine is a personal choice rather than a proven fix.
