Creatine Hair Loss: Is It A Myth or Fact?

A lot of bodybuilding supplements get a bad rap for causing hair loss. One of them is creatine – a performance-enhancing substance (ergogenic aid) that’s popular with athletes as well. It was a paper published back in 2009 that fuelled these rumours. 

There are many who complain of creatine hair loss, going completely bald even after taking it. But many are still unsure if there’s any truth to it. That’s because creatine is only an amino acid derivative, after all. And they’re right in questioning the myth’s veracity.

What Is Creatine?

Creatine is an amino acid that’s found naturally in the human body. And according to the International Society of Sports Nutrition (ISSN), creatine (monohydrate) is “the most effective nutritional supplement.”

Creatine occurs naturally in some of the foods we eat, like red meat and fish. Only 1% of it makes up the human blood. 95% of it is found in the muscle mass, while the remaining 5% is in the brain.

Although it is not regulated by the US Food and Drug Administration (FDA), it has a GRAS (General Recognized as Safe) status. 

It is considered safe to consume 3-5 grams of creatine  (or 0.1/kg of body mass) daily. There are some studies that have shown that it can be safely taken for years.

However, it is important that you consult your doctor before you even start taking it. 

Other than powder and tablet supplements, you can also get creatine energy drinks and bars.

How Creatine Works?

In the body, creatine is converted into creatine phosphate, which is used to produce energy (ATP) for muscles.

Creatine is thought to build muscles in different ways. For instance, it retains water, making the muscles appear puffier. Additionally, it increases energy production which enables a person to work out more. It also reduces muscle breakdown and promotes its growth.

Athletes use it for improving their exercise capacity and increase lean muscle mass. However, because it increases muscle mass and strength, it’s also used by many bodybuilders and gym-goers.

What Are The Benefits of Taking Creatine?

Creatine can do more than just help build lean muscle mass. It may have other benefits like the following: 

  • Quicker recovery after an intense training session 
  • Decreased likelihood of injury to the musculoskeletal system
  • Improved capacity to exercise in the heat/better heat tolerance 
  • Reduced muscle cramping 
  • Antioxidant effect scavenges free radicals 

Other than that, it has also been shown to help with different diseases among young and old. It may:

  • Reduce brain damage (neuroprotective) 
  • Work as an antidepressant 
  • Help with creatine deficiency syndromes (AGAT, GAMT, CRTR-D) 
  • Work as a treatment for neurodegenerative diseases like Huntington’s, Parkinson’s and ALS (US National Library of Medicine deems it “possibly ineffective” for ALS and Huntington’s)
  • Help with fatigue 
  • Slow down the loss of muscle mass with age, a condition known as sarcopenia 
  • Improve cognitive abilities like memory and intelligence

What Are The Side Effects Of Creatine?

In general, creatine is considered safe. Its intake can, however, cause some side effects, such as: 

  • Muscle cramping
  • Upset stomach 
  • Irregular heartbeat 
  • Bloating 
  • Dehydration 
  • Nausea and dizziness

Creatine is contraindicated for use in individuals with kidney disease. Additionally, some say it could cause kidney damage, but more research is needed in this regard.

Other than that, people with diabetes and bipolar disorder are cautioned against its use.

Drinking coffee with creatine if you have Parkinson’s can worsen it, so you need to avoid that.

Lastly, breastfeeding or pregnant women are advised not to take it.

What Will Happen If You Stop Taking Creatine?

Once you stop taking creatine, it will cause some temporary side effects, such as:

  • Fatigue 
  • Muscle weakness 
  • Reduced muscle mass
  • Loss of water weight 

These effects can last for a few weeks.

Keep in mind that when you stop taking creatine supplements, your body won’t immediately start producing normal levels of creatine.

As your body has been relying on supplements to do the job, it will take some time for it to start producing creatine normally.

How Does Creatine Affect Hair?

To date, no scientific research has investigated the direct relationship between creatine and hair loss.

The idea that creatine affects hair comes from its relationship with testosterone.

When you work your muscles out, it will result in the release of testosterone.

From there, it’s argued that testosterone will increase the levels of dihydrotestosterone (DHT) – a by-product of testosterone that causes hair loss due to androgenetic alopecia.

Testosterone to DHT
DHT causes pattern baldness

If that were true, anyone who works out would lose their hair. And that’s definitely not the case.

It all comes down to your genetics. If you’re genetically predisposed to losing your hair, that – not creatine – will affect your hair follicles.

Does Creatine Cause Hair Loss?

One of the most talked about creatine side effects is hair loss. However, the truth is the two are not related.

According to a literature review published in the Journal of the International Society of Sports Nutrition (JISSN), creatine does not cause hair loss. That’s because it has no effect on the levels of testosterone or dihydrotestosterone in the body.

DHT is mainly responsible for androgenetic alopecia. It binds to hair follicles and results in their miniaturization.

This goes on until you’re left with no hair on the top and front of your scalp.

What Started The Creatine Hair Loss Myth?

In 2009, one study published in the Clinical Journal of Sport Medicine indicated that creatine baldness might be a thing.

In this study, college-aged male rugby players took creatine supplements with glucose (which helps increase creatine intake) for 3 weeks.

Rugby players creatine study 1 4
Study on the intake of creatine supplements by rugby players fuelled creatine hair loss rumours

For 7 days, the participants took 25 grams of creatine per day with 25 grams of glucose.

The placebo group took 50 grams of glucose per day.

After the 1 week “loading period,” there was the “maintenance phase,” which lasted for 14 days.

In this, the players took 5 grams of creatine with 25 grams of glucose per day in contrast to the placebo, which had 30 grams of glucose only.   

After 3 weeks, it was found that the DHT levels of the rugby players had increased by 56% in the “loading period” and 40% in the “maintenance phase.” Also, this difference was “statistically significant” from the placebo group. 

Now the problem with the study was that the increase in DHT that did happen was not above the “clinically normal values.” The players had low levels of DHT (lower than normal) before they took creatine.

So, when it increased a little (with a subsequent decrease in the placebo group’s DHT levels), the results were given more credence. 

In reality, the authors of the study don’t even report on the rugby players experiencing hair loss during the study.

Furthermore, research shows that testosterone levels increase in men when they perform resistance exercises. So, the increase in the DHT hormone may not have been a result of creatine at all.

In addition, the study has not been replicated, so it’s hard to make any definitive conclusions on creatine and DHT hair loss.

Therefore, all the remaining evidence on this is purely anecdotal. It is possible that the time around which you start taking these supplements coincides with the onset of genetic alopecia.

This can explain thinning or baldness. However, creatine hair loss isn’t what’s happening to you.

Is Creatine Hair Loss Permanent? 

So far, there’s no evidence that creatine in hair causes baldness.

People who experienced it have reported that hair loss stopped once they stopped using it. But if your hair loss is actually due to androgenetic alopecia, it will be permanent. 

There’s no saying, however, that creatine can even cause it.

It should be noted that pattern baldness can occur at normal levels of testosterone in the body.

The AR gene (Androgen Receptor) makes some follicles in the scalp more sensitive to the presence of DHT.

An imbalance can exacerbate this kind of hair loss, sure, but it doesn’t mean that it won’t take place at all.

That means if you are genetically predisposed to androgenetic alopecia, you will eventually lose your hair anyway, even if you don’t take creatine. 

There are some people who confuse it for an anabolic steroid. While those actually do affect the male sex hormones and can cause pattern baldness, creatine is an entirely different substance in its chemical structure.

Therefore, creatine hair loss cannot take place for that reason, either. 

How To Prevent Creatine Hair Loss?

Since hair loss is not associated with creatine, taking any preventative measures is not necessary.

However, if you’re taking creatine, and you have pattern baldness (the former is not related to the latter), you might benefit from different hair loss treatments.

For instance, there are 5-alpha-reductase inhibitors like finasteride and dutasteride. Minoxidil is another drug that’s used to stimulate hair growth.

Laser and PRP injections might also help you. However, hair transplant is the only surgical option that gives permanent results.

When Should You See A Doctor?

It’s best to consult a doctor before you start taking creatine for whatever reason.

That’s because it may not be safe for use in some individuals.

If after you’ve started taking it and you’re experiencing adverse side effects, you should immediately get in touch with your doctor. 

About hair loss, if it’s sudden and excessive, you need to go to your doctor for a physical exam and even some tests. You may be suffering from an underlying health condition.

Concluding Remarks 

Creatine hair loss has been much talked about since the study got to social media. It’s well-established that testosterone gets converted into DHT with the help of the enzyme 5-alpha reductase. 

This by-product of testosterone then binds with the androgen receptors on hair follicles, shrinking them over time and bringing an end to the growth cycle. It’s only some hair on the head that is sensitive to the presence of these hormones. Therefore, you don’t go completely bald. 

The study mentioned above shows that the levels of DHT increase from creatine supplementation, so it can possibly result in hair loss among individuals who are predisposed to pattern baldness. 

However, there are many flaws in the study, such as: 

  • The baseline DHT levels of the rugby players were lower than normal, so even a small increase to normal values with a slight decrease in DHT in the control group made the results “statistically significant.” 
  • The study doesn’t note any hair loss experienced by the players themselves. 
  • The participants were taking far, far more creatine than the daily recommended intake. 
  • Their exercise itself could result in an increase in the androgens. 
  • The sample size was too small (16 males) to make any generalisations. 

Therefore, it can be concluded that there’s no link between creatine and hair loss. There are some studies that have tried to investigate the relationship between testosterone levels and creatine, and so far, nothing’s been found.
