Does Creatine Cause Hair Loss? What the Research Says

No. For most people, creatine does not cause hair loss. There is no strong scientific evidence that taking creatine makes your hair fall out. The whole worry traces back to a single 2009 study that measured a hormone, not actual hair, and was never repeated, while a 2025 trial that looked directly at hair follicles found no effect. The one honest caveat: if you are genetically prone to pattern baldness, it is worth understanding the hormone angle and talking to a dermatologist. Here is the full picture.

Does creatine cause hair loss?

The short answer is no, not based on the evidence we have. Creatine monohydrate is one of the most studied supplements in the world, and the research does not show it triggers hair loss or balding in healthy people. Hair thinning is driven mostly by genetics, age, and hormones, not by a scoop of creatine.

The most direct test came in 2025. A 12-week randomized controlled trial was the first to look specifically at hair follicle health and hormones during creatine use. It found no significant differences in DHT, the DHT-to-testosterone ratio, or hair growth measures between the creatine group and the placebo group. Major health publishers, including Cleveland Clinic, land in the same place: the hair loss fear is not supported by the science.

Where did the creatine hair loss myth come from?

One study, in 2009. Researchers gave college rugby players creatine and measured their hormones over three weeks. They saw a rise in dihydrotestosterone (DHT), a hormone linked to male pattern baldness in people who are genetically sensitive to it. That is the entire origin of the rumor.

Here is the problem with treating that as proof: the study measured a hormone marker, not hair. Nobody counted hairs, measured follicles, or documented anyone going bald. It ran for only three weeks, in one small group of athletes, and no study since has reproduced even that hormone change. A single, short, hormone-only study became a decade of gym-bro warnings, which is exactly the kind of hype-over-substance noise the supplement world runs on.

What does the latest research actually show?

When researchers finally tested the claim head-on, it did not hold up. Here is how the rumor compares to the evidence.

Independent research reviewers reach the same verdict. Examine.com, which has no supplement to sell you, puts it plainly: it seems unlikely that supplementing with creatine causes hair loss.

Does creatine raise DHT?

This is the real question hiding under the myth, and the honest answer is "the evidence is mixed and leans toward no." The 2009 study reported a short-term increase in DHT. The larger, more recent and more direct 2025 trial found no significant change in DHT or the DHT-to-testosterone ratio over 12 weeks. So the one alarming data point has not been confirmed, and the best current study points in the opposite direction.

Even in the worst-case scenario, raising DHT is only relevant if your follicles are genetically sensitive to it. For everyone else, a small hormone shift does not translate into thinner hair.

Should anyone be cautious about creatine and hair?

Yes, one group should think it through. If you have a strong family history of male or female pattern baldness, your follicles may already be sensitive to hormones, and any factor that nudges hormones could, in theory, speed up a process your genes already started. That is a "talk to a dermatologist" conversation, not a reason for everyone to avoid creatine.

It also helps to remember how many things cause hair shedding that have nothing to do with your supplement shelf: genetics, aging, stress, crash dieting, illness, and hormonal changes like postpartum or menopause. If your hair is thinning, blaming creatine can lead you to chase the wrong cause. See a healthcare provider or dermatologist to find the real one.

What are creatine's actual side effects?

If hair loss is off the list, it is worth knowing what is actually on it, because the real side effects are mild and well documented. The most common is a small amount of water weight in the first week or two, drawn into the muscle rather than sitting under the skin as bloat. Some people get minor stomach upset from taking a big dose all at once on an empty stomach, which splitting the dose or taking it with food usually solves.

The kidney-damage rumor is another myth for healthy people: at standard doses, creatine has not been shown to harm normal kidney function. If you have a kidney condition or take medication, check with your provider before starting. Notice what is not on the list of documented effects: hair loss.

So is creatine still worth taking?

For most people chasing strength and performance, yes. Creatine helps your muscles regenerate ATP, the energy they burn during short, hard efforts, and when paired with resistance training, it has been shown to support strength, power, and lean mass. That is a large, consistent body of evidence, set against a hair loss fear built on one hormone reading from 2009.

If you want a creatine that is dosed in plain sight, FitBoost+ provides 3 grams of creatine monohydrate per scoop alongside Peak ATP, electrolytes, and 95 mg of caffeine, with zero sugar and the creatine listed at a clear 3 grams rather than buried in a blend. Because it contains caffeine, it is not the pick if you are avoiding stimulants or are pregnant or breastfeeding. If you prefer creatine on its own, plain monohydrate works too.
