Creatine is a widely researched sports nutrition supplement, but concerns persist regarding whether it causes hair loss. This worry stems from discussions linking dihydrotestosterone (DHT)—a hormone associated with certain types of hair thinning—to creatine. However, a rise in hormone levels does not automatically equate to hair loss.
An early study reported increased DHT levels following creatine supplementation, but it did not examine actual hair loss. More recently, a 2025 randomized controlled trial measured both androgen levels and hair follicle characteristics, finding no significant differences between creatine and placebo groups. Together, these findings suggest that current human research does not support a causal relationship between creatine supplementation and hair loss.
Creatine is a naturally occurring compound involved in the body’s energy system. It is stored largely in skeletal muscle, where phosphocreatine helps rapidly regenerate ATP during short-duration, high-intensity activity. The body produces creatine naturally, and dietary sources include foods such as meat and fish. Creatine is also available as a dietary supplement, with creatine monohydrate being the most extensively studied form.
People use creatine primarily in connection with exercise, strength and physical performance. Research has also examined creatine in other areas, including cognitive performance, healthy aging and recovery. Project Creatine focuses on explaining this research and helping consumers distinguish established findings from creatine myths and misconceptions.
One of the most persistent misconceptions is that creatine automatically causes baldness. To understand where that concern came from, it is necessary to look at the evidence surrounding DHT.
Much of the discussion around whether creatine causes hair loss can be traced to a small 2009 study involving 20 college-aged rugby players. The researchers investigated testosterone and DHT levels after participants used a creatine supplementation protocol.
The study reported an increase in DHT following the supplementation period. However, it did not measure hair loss, hair density, follicle thickness, or other direct hair-related outcomes. Therefore, the findings did not establish that creatine supplementation causes hair loss.
This distinction is important because changes in hormone levels do not necessarily translate into changes in hair growth or hair loss. A change in a biological marker can provide a reason for further research, but it does not automatically demonstrate a clinical outcome. The study itself provided a basis for further investigation rather than establishing a direct relationship between creatine supplementation and hair loss.
Dihydrotestosterone, commonly called DHT, is an androgen produced from testosterone. Researchers have studied DHT in connection with certain patterns of hair thinning, particularly in people who may be genetically susceptible. However, the relationship between DHT and hair changes is more complex than simply measuring whether DHT levels increase or decrease. Individual biology, genetics and follicle sensitivity can all influence how hair changes over time.
This is why research investigating creatine hair thinning needs to look beyond hormone measurements. Ideally, studies should also examine direct hair-related outcomes, such as hair density, follicular characteristics or changes in hair thickness. The available evidence should therefore be interpreted carefully rather than assuming that a change in DHT automatically means that creatine causes hair loss.
The relationship between creatine and DHT is one reason concerns about hair loss have persisted. A 2009 study reported higher DHT levels following a creatine supplementation protocol in a group of college-aged rugby players. However, the study did not assess hair loss or changes in hair follicles.
A later randomized controlled trial investigated the issue more directly. Participants receiving 5 g of creatine monohydrate daily for 12 weeks were assessed for androgen levels as well as several hair-related measures. The researchers reported no significant differences between the creatine and placebo groups in DHT, the DHT-to-testosterone ratio, or the measured hair parameters.
Taken together, these findings do not establish that creatine supplementation causes hair loss through changes in DHT.
The strongest evidence currently available comes from a 2025 randomized controlled trial specifically designed to investigate whether creatine supplementation affects hair follicle health.
The study involved 45 resistance-trained males aged 18–40 who were randomly assigned to either creatine monohydrate at 5 g per day or placebo. The researchers followed participants for 12 weeks and assessed testosterone, DHT and several hair-related outcomes.
Importantly, the researchers did not simply measure hormones. They also assessed hair follicle health using trichogram testing and the FotoFinder system, including measurements related to hair density, follicular unit count and cumulative hair thickness.
After 12 weeks, researchers found no significant differences between the creatine and placebo groups in DHT levels, the DHT-to-testosterone ratio, or the measured hair-growth parameters.
Unlike the 2009 study, which measured hormone levels alone, the 2025 trial directly assessed hair follicle characteristics, providing more relevant evidence about the potential relationship between creatine supplementation and hair loss.
It means the current evidence does not establish a causal relationship between creatine supplementation and hair loss.
It does not mean researchers can prove that hair loss is impossible for every person taking creatine. No individual study can establish that. Instead, it means that the best direct human evidence currently available does not support the claim that creatine causes hair loss.
The term creatine alopecia is sometimes used online to describe suspected hair loss associated with creatine supplementation. However, creatine alopecia is not an established clinical diagnosis showing that creatine itself causes androgenetic alopecia.
The distinction matters because hair loss has many potential causes. Someone may begin taking creatine around the same time they notice increased shedding, but timing alone does not prove that one caused the other. For example, androgenetic alopecia can develop gradually and may become noticeable during the same years that someone begins exercising, changing their diet or using supplements.
Other types of hair loss can also have different triggers. Rapid shedding can occur following illness, significant stress, nutritional deficiencies, hormonal changes or other circumstances.
Consequently, if someone experiences noticeable hair loss after beginning a supplement, it is more useful to investigate the underlying cause than to automatically assume that creatine is responsible.
The creatine and hair loss discussion has generated several common misconceptions.
Not necessarily. DHT is involved in androgenetic alopecia, but hormone levels alone do not establish that hair follicles are being affected.
It did not. The study measured androgen levels but did not measure hair loss or follicle health.
A family history can be relevant when considering patterns of hair thinning, but current research does not establish creatine supplementation as a cause of hair loss. A family history alone is therefore not sufficient evidence to conclude that someone will experience hair-related changes from creatine.
A temporal association is not proof of causation. If significant or persistent shedding occurs, other potential causes should be considered and evaluated appropriately.
These distinctions are central to understanding creatine myths and misconceptions without overstating either the risks or the benefits of supplementation.
Research examining creatine supplementation and hair loss in women remains limited, as most direct human studies on this topic have involved men.
A 2025 randomized controlled trial investigated creatine supplementation and hair-related measures in healthy, resistance-trained males aged 18–40. The researchers did not find significant differences between the creatine and placebo groups in the hair measurements assessed during the 12-week study. However, these findings cannot be directly extended to every woman because the study population was male. Research specifically examining creatine supplementation and hair-related outcomes in women remains more limited.
Therefore, current evidence has not established a causal relationship between creatine supplementation and hair loss in women. If someone experiences persistent or noticeable changes in their hair after starting any supplement, the appropriate next step is to discuss those changes with a qualified healthcare professional rather than assuming the supplement is responsible.
Another frequently searched question is does creatine help with hair loss.
There is currently no established evidence supporting creatine as a treatment for hair loss or hair thinning. Creatine research primarily examines areas such as physical performance, strength and exercise-related outcomes, while research into other potential applications continues to develop.
For that reason, creatine should not be presented as a treatment for hair-related conditions.
Project Creatine’s purpose is to provide educational information about creatine and the research surrounding it. Questions about persistent hair thinning, shedding or other changes should be discussed with a qualified healthcare professional who can evaluate the individual circumstances. |
Creatine monohydrate is the most extensively researched form of creatine. It is available in powders, creatine monohydrate capsules, and other supplement formats. There is currently no established evidence showing that switching between common creatine delivery formats prevents hair loss.
If you are comparing products, focus on the actual ingredient, serving information, formulation and quality rather than choosing a product based on unsupported claims about hair protection.
Project Creatine’s educational resources are designed to help consumers understand these distinctions rather than turning an unproven concern into a product claim.
If you experience persistent or concerning changes in your hair or scalp, speak with a qualified healthcare professional or dermatologist for appropriate evaluation.
Hair changes can have many possible causes, and an online article cannot determine the reason for an individual’s symptoms. A healthcare professional can assess the situation and determine whether further evaluation is appropriate. If you have concerns about creatine or another supplement in relation to your individual health circumstances, discuss those concerns with an appropriate healthcare professional.
So, does creatine cause hair loss? Current human research has not established a causal relationship between creatine supplementation and hair loss. While a 2009 study raised questions about changes in DHT levels, it did not measure hair loss. A more recent 2025 randomized controlled trial examined actual hair follicle characteristics and found no significant differences between creatine and placebo groups.
These findings provide reassurance, but additional research involving larger and more diverse populations would help strengthen our understanding. At Project Creatine, our goal is to make creatine research easier to understand and help people distinguish established findings from common misconceptions.

There is no established timeframe because research has not demonstrated that creatine supplementation causes hair loss. In a 2025 randomized controlled trial, researchers found no significant differences in hair-related outcomes between creatine and placebo groups after 12 weeks.
Current evidence does not establish creatine as a cause of hair loss in women. However, direct hair research has been more limited in women, so persistent hair loss should be evaluated based on its individual pattern and potential causes.
There is no established evidence that creatine treats or prevents hair loss. It should not be used as a treatment for alopecia without appropriate professional guidance.
Current direct human evidence does not show that creatine supplementation makes people lose hair. The concern largely comes from an earlier study that measured DHT but did not measure hair loss.
