Creatine and hair loss: what we actually know

Probably not. The idea that creatine causes hair loss comes from a single small trial from 2009, with 20 rugby players, which measured a rise in dihydrotestosterone (DHT) in the blood but never assessed hair at all. In 2025, a randomised controlled trial of 45 trained men compared creatine with placebo for 12 weeks and found no differences in hair density or in any other follicle measure. That does not close the question forever, but it is the best evidence there is right now — and it is a good deal more reassuring than the version going round social media.

If you have arrived here with a tub in your hand and a doubt in your head, take this much away: the available evidence does not support the idea that creatine causes hair loss in young, healthy men taking it for three months. The rest of this page explains where the confusion came from, what we still do not know, and what to do if your hair really is changing.

Where the story that creatine causes hair loss came from

In 2009, a group of researchers gave creatine to 20 university rugby players, as a loading phase followed by maintenance, and measured hormones in the blood. DHT rose 56% after seven days of loading and stayed around 40% above baseline after 14 days of maintenance. Testosterone did not change. The ratio of DHT to testosterone rose 36% and then 22%.

Look at what the study did and what it did not do. It measured hormones. It did not measure hair, did not count follicles, did not photograph any scalps. Twenty people is a tiny sample, and a crossover design in young athletes does not represent the general population. The authors themselves wrote that more research was needed and that the long-term clinical safety of those changes in circulating androgens could not be guaranteed.

That was enough. A sentence of caution hardened, within a few years, into the certainty that creatine makes you bald.

What has changed since

In 2025 a randomised controlled trial was published comparing 5 g of creatine monohydrate daily with placebo for 12 weeks, in 45 men doing resistance training, aged 18 to 40. Thirty-eight completed the study. The researchers measured DHT, the DHT-to-testosterone ratio, and hair growth parameters: density, number of follicular units and cumulative hair thickness.

There were no significant differences between the groups on any of those measures. The authors describe the work as the first to assess follicle health directly after creatine supplementation, and state that the results are strong evidence against the claim that creatine contributes to hair loss.

A 12-week trial in young, healthy men cannot speak for someone who has taken creatine for ten years, nor for women, nor for people with other health conditions.

Is DHT actually linked to baldness?

Yes, and that part is solid. Male-pattern baldness, or androgenetic alopecia, is related to hormones called androgens, in particular DHT, according to MedlinePlus Genetics. Various genetic and environmental factors probably contribute to its appearance.

The reasoning that joins the dots is simple: if DHT is associated with baldness and one study showed that creatine raises DHT, then creatine must cause baldness. The problem is the leap. A hormonal association is not a cause-and-effect relationship with hair loss, and the 2025 trial found no hair changes even while measuring exposure across three months.

If your hair is changing, what is usually behind it

Hair loss has several causes and not all of them are permanent. The NHS separates them into two groups. Some types are permanent, such as male and female-pattern baldness, which usually comes with a family history. Others are temporary and may be triggered by illness, stress, cancer treatment, weight loss or iron deficiency.

Before you blame the creatine powder, it is worth looking at what has changed in the last few months. Have you started a restrictive diet? Have you had an infection, surgery or a stretch of intense stress? Are you eating enough? Iron deficiency, for one, is a recognised cause of temporary shedding and it will not be fixed by creatine supplements.

It also helps to know that hereditary baldness is related to hormones called androgens, in particular dihydrotestosterone (DHT), and that various genetic and environmental factors probably play a part in causing it. A sudden, diffuse shed, with hairs on the pillow and in the shower, reads differently and deserves to be assessed.

What to do this week, before you decide anything about creatine

There is no miracle protocol here, and any promise to reverse hair loss in seven days is talk. What makes sense is separating what you can observe from what needs someone else to assess it.

• Photograph your scalp in good light, in the same position, today. Repeat it in three months. Without that reference point, any judgement is memory, and memory misleads.
• If you are taking creatine and are unsure, you do not have to decide today. You can keep taking it and watch, or stop and see what happens — but know that a visible change in hair is rarely readable in weeks.
• Review your food and your rest before adding more tubs to the cupboard. Temporary shedding from illness, stress or weight loss is not fixed by a supplement.
• If the loss is recent, rapid or comes with other symptoms, book an appointment. The NHS advises speaking to your GP when hair loss is worrying you, so that the cause can be identified.

What probably will not help

Switching creatine brand solves nothing if the problem did not come from creatine in the first place. Changing format — powder to gummies, gummies to capsules — does not change the molecule either: it is still creatine monohydrate, and creatine monohydrate is precisely what the 2025 trial tested.

So-called strengthening shampoos, homemade rosemary recipes and supplements sold as DHT blockers circulate widely, but the available evidence does not support the idea that they stop hereditary baldness. We are not assessing them here because we do not have the data to do it — and that absence of data is itself the useful information. If someone promises to halt hereditary baldness with a bottle, ask for the evidence.

Panicking and stopping everything at once does not help either. If you quit the creatine, the training, the diet and the shampoo in the same week, you can no longer work out what changed what.

Where supplements honestly fit into this conversation

This is the part where a lot of brands lose their shame. No supplement here treats, prevents or reverses hair loss, and creatine is no exception. The available evidence on creatine and hair says only this: the likelihood of it causing hair loss looks low, according to the 12-week trial cited above.

If you already take creatine as part of your training and want to keep the format, Creatine Gummies are one option in our range: three gummies provide 5000 mg of creatine monohydrate and 50 µg of vitamin B12, and they are intended for adults. The label directs you to chew three gummies per day, preferably after a meal, and not to exceed the recommended daily dose. They contain polyols, and excessive consumption may produce laxative effects. Like any food supplement, they are not a substitute for a varied and balanced diet and a healthy lifestyle, and they should be kept out of reach of young children.

None of that is an answer to hair loss. It is simply a way of taking creatine, if that is what you are after.

How long before you can actually judge

The longest trial we have in this area ran for 12 weeks. That is the horizon the evidence speaks to: three months of creatine, in young, healthy men, with no changes in the hair parameters measured.

Beyond that, we do not know. There are no data covering years of use, women, teenagers, people with alopecia already established, or people taking medication. To say otherwise would be to make it up. If you are planning an observation period, three months is a reasonable window for comparable photographs and, if relevant, for a GP appointment — not because hair changes entirely in that time, but because it is the interval the available evidence covers.

When this stops being a doubt and becomes a medical problem

Worry about creatine and hair is not supported by the available evidence, and in that case the answer is to be reassured and carry on. There are signs, though, that change the conversation.

• Rapid hair loss over a few weeks, especially in patches or with clearly defined bald spots.
• Shedding alongside severe fatigue, weight changes, skin problems or symptoms that do not explain themselves.
• A strong family history of baldness with an early start to the receding hairline, which warrants assessment to work out what is happening.
• Significant emotional impact — avoiding going out, avoiding mirrors, avoiding photographs. That is reason enough to seek help.

In any of these cases, speak to a doctor or a pharmacist. The NHS is clear: if hair loss is worrying you, see your GP to find out the cause. No supplement fixes a cause that nobody has identified.

The honest limit of what we know

We have one small 2009 study that raised DHT and never looked at hair, and one 2025 trial, also small, that looked at hair and found no differences. The second is better designed and answers the question directly, but 45 participants over 12 weeks is neither a crowd nor a lifetime. The evidence is emerging, not definitive, and anyone telling you it is all settled has gone beyond the data.

What you can do with this: keep the creatine if it serves your training, without disproportionate fear; track your hair with dated photographs rather than impressions; and if something changes quickly or worryingly, take it to someone who can assess it. Creatine is the easy part of this equation. Hair deserves a proper conversation, not a label.
