Does Creatine Cause Hair Loss?

Creatine has long been a go-to supplement for fitness enthusiasts seeking to improve strength, endurance, and muscle mass. However, one question continues to resurface in gym circles and online forums alike: Does creatine cause hair loss? This concern, often referred to as an urban legend, has caused hesitation for many potential users. This concern, often referred to as an urban legend, has caused hestitation for many potential users. The origin of this concern dates back to a 2009 study that sparked widespread debate and fear. 

In that study, creatine was linked to an increase in dihydrotestosterone (DHT) levels, a hormone associated with male pattern baldness. While the study didn't directly prove that creatine caused hair loss, the potential link to increased DHT was enough to trigger alarm. This theory was rapidly picked up by social media and quickly became accepted as truth by many. 

Revisiting the Research in 2025

Fast forward to 2025, and the conversation around creatine and hair loss has taken a new direction thanks to a recent, more comprehensive study. This randomized controlled trial involved 45 healthy males, ages 18 to 40, and spanned a 12-week period. Participants were divided into two groups: one received five grams of creatine monoydrate, while the other received a placebo. 

Researchers measured total testosterone, free testosterone, and DHT levels through blood samples. They also assessed hair follicle health using the Trichogram test and FotoFinder system - advanced diagnostic tools that evaluate hair density, follicular unit count, and cumulative hair thickness. 

This approach was far more thorough than the original 2009 study, offering both hormonal and physical analysis of hair health. 

The Results: No Increase in DHT, No Hair Loss

The findings were clear: there was no significant increase in serum DHT levels among those taking creatine compared to the placebo group. Even more reassuring was the fact that no signs of hair loss were observed in the creatine group over the course of the 12 weeks. 

That means no noticeable reduction in hair density or thickness, and no evidence of shedding. For a study spanning three months - long enough to typically see hair changes from stronger hormonal supplements like steroids - these results are highly encouraging. 

A Balanced Perspective

While the study offers reassuring news, it's important to consider the limitations. With only 45 participants, all of whom were healthy males, the findings may not be fully generalizable to every population. However, the study does provide strong evidence that creatine monohydrate does not cause hair loss - at least in the short term and in healthy individuals. 

Compared to other hormone-altering substances, which often show hair-related side effects within weeks, creatine appears to be a much safer bet for maintaining your mane. 

The Takeaway

For those worried about their hairline, this new research provides a welcome dose of clarity. Creatine monohydrate remains a safe and effective supplement for boosting athletic performance and according to the latest study, it's unlikely to have any impact on your hair health. 

As with any supplement, individual results may vary, but current evidence strongly suggests you can continue taking creatine without fear of losing your hair.
