Creatine and hair loss: what the clinical evidence says (and how to care for your hair if you take it)

Creatine monohydrate is one of the most well-supported supplements for performance in intense efforts. And, at the same time, it's one of the ones that generates the most questions in consultations: can it cause hair loss?

We explain how we would address it in a consultation: with clinical evidence, context (remember that hair doesn't respond overnight), and a practical plan if you train hard and want to take care of your hair with a serious approach.

The Evidence-Based Answer

The concern about creatine and hair loss became popular following a 2009 study that observed changes in DHT. DHT (dihydrotestosterone) is a hormone derived from testosterone. In people with a genetic predisposition to androgenetic alopecia, DHT can, over time, contribute to some follicles becoming smaller (miniaturization) and hair becoming thinner. Therefore, when "DHT increases" is mentioned, it's normal for an alarm to go off.

However, the clinical nuance is important: that 2009 study did not evaluate hair (it did not measure hair loss, density, thickness, or follicular miniaturization). That is to say, it could open a hormonal hypothesis, but it could not conclude that creatine causes alopecia.

In trichology, what is decisive is not only whether a marker in the blood varies, but whether real changes are observed in the follicle and hair: density, thickness, growth phase, and, above all, objective hair loss.

That's why the clinical trial published in 2025, which did directly evaluate hair and follicles in addition to hormones, is especially relevant. It was a randomized, double-blind, placebo-controlled study, lasting 12 weeks, comparing creatine versus placebo. In addition to measuring DHT, it analyzed hair parameters with instrumental techniques (including density, follicular units, and accumulated thickness).

Result: no differences were found between creatine and placebo in either DHT or hair/follicle parameters. In other words, with the available clinical data, there is no direct evidence that creatine contributes to hair loss.

It does coincide with hair loss: telogen effluvium and training

When someone notices more hair loss when starting creatine, it almost always coincides with changes in the “pack” that accompanies creatine:

• More training intensity and insufficient recovery: Exercise (especially intense) can modulate the stress axis and hormonal responses, including cortisol, and recovery (sleep, rest, energy) is crucial.
• Energy deficit (very common in "cutting" phases). I increase training, decrease calories, cut carbs, sleep worse..., and the follicle suffers. The hair follicle is an organ that demands a lot of energy and nutrients and is not essential for the body; other systems must be prioritized first.
• Telogen effluvium: the typical pattern of hair loss "by context". Telogen effluvium is the most frequent cause of diffuse non-scarring hair loss and usually appears 2-3 months after a trigger (physical/mental stress, diets, illness, postpartum, etc.). Evaluating this fact means you can't attribute it to creatine.

Often, what is attributed to creatine is actually a telogen effluvium triggered by training + stress + energy deficit + insufficient rest.

What to do?

Step 1. Identify the pattern

• Diffuse hair loss (more hair in the shower/brush, with no clear areas): suggests telogen effluvium.
• Progressive thinning at the temples/crown, with a family history: suggests androgenetic alopecia (here a dermatological/trichological evaluation is always advisable).

Step 2. Order what most impacts the follicle

• Sufficient energy (especially if you train intensely).
• Protein and micronutrients (be careful not to duplicate supplements).
• Real recovery: sleep + deload days.

Step 3. Give time to the hair cycle

Hair doesn't respond as quickly as a muscle. To assess changes in shedding and quality, a reasonable window is 8-12 weeks (and sometimes more, depending on the case).

How Hair Boost can help you if you take creatine

Your goal with Hair Boost is not to "counteract" creatine. It is to support the follicle and fiber during demanding periods (training, stress, diets), with a balanced and traceable formula, without mega-doses.

These are the most relevant clinical axes of your formula:

Support for the hair cycle and shedding: AnaGain™ (pea sprout extract)

There is a clinical evaluation of a pea sprout extract (AnaGain™) with daily intake for 8 weeks associated with a reduction in hair shedding in people with increased hair loss.

How we explain it in consultation: it is an interesting active ingredient as an adjuvant when the main problem is "I'm losing more hair", especially in diffuse hair loss.

Structural substrates for fiber and fragility: L-cystine + hydrolyzed keratin (Cynatine®)

• Cynatine® (hydrolyzed keratin): there is a randomized, double-blind, placebo trial that evaluated hair and nail parameters with favorable results compared to placebo.
• L-cystine: fits as a key sulfur amino acid in keratin structure; in addition, there are recent trials of supplements that include L-cystine in populations with hair loss (as part of combined formulas).

How we translate it for the client: if your problem is "hair loss + more fragile hair", not everything is the follicle: fiber quality also matters (less breakage, better feel, more consistency).

Stress and recovery (very relevant if you train intensely): Sensoril® (ashwagandha)

There are placebo-controlled trials in adults with stress where ashwagandha extracts showed improvements in stress scales and cortisol reduction.

Clinical safety note (important): although it is usually well tolerated in trials, there are rare cases of liver injury associated with ashwagandha products (according to clinical compilations such as LiverTox/NIH and reports). Therefore, standardization, traceability, and batch control are key, and its use should be avoided during pregnancy/lactation or in people with a history of liver problems without medical supervision.

"Precision" micronutrients, without exceeding: zinc, selenium, copper, vitamins C/E, B6

• Zinc: low zinc has been associated with chronic telogen effluvium in observational studies; this does not mean that "everything is zinc", but it is a frequent point to review.
• Selenium: here I like that you indicate that recommended values are not exceeded. Excess selenium can cause alopecia and nail changes (selenosis) in clinical reports.

Consultation translation: for micronutrients, dosage is part of safety. Support, yes; "doubling just in case", no.

Usage pattern and precautions

If you take creatine daily (e.g., 3-5 g/day):

• Maintain creatine as you tolerate it (with food or post-workout, consistency is important).
• Take Hair Boost with a main meal.
• Evaluate results with a realistic window: 8-12 weeks (ideally with comparable photos and controlling variables: sleep, diet, stress, hair routine).
• Avoid a common mistake: duplicating micronutrients.
• If you already take a multivitamin or other supplements, especially check zinc and selenium so you don't inadvertently add them up. (More is not better; in the case of selenium, it can be counterproductive).
• Remember that following an adequate hair care routine: the (Inside)Out Method, which combines Hair Boost as a dietary supplement with an effective cosmetic ritual, is one of the most successful strategies for promoting and maintaining healthy hair.

When to consult about your hair loss

We always recommend that you consult privately with a dermatologist/trichologist or your pharmacist/doctor if:

• hair loss is intense or lasts 8-12 weeks,
• there is visible thinning or patches,
• marked itching/scaling appears,
• or there are symptoms suggesting systemic causes (marked fatigue, very heavy periods, thyroid changes, etc.).

And remember: telogen effluvium is usually self-limiting, but patient education (what it is, how long it lasts, what to expect) is part of the treatment.

In summary for your peace of mind

If you take creatine and are in a period of intense training, the goal is not to avoid creatine out of fear, but to take care of the follicle's context: sufficient energy, recovery, and balanced nutritional support.

Hair Boost is designed as support for those times when we have to face higher nutrient demands due to its standardized active ingredients and key micronutrients. If you decide to incorporate it, use it consistently for 8-12 weeks and evaluate it judiciously (I always recommend doing so with comparable photos and keeping training and diet stable).

FAQ

Does creatine cause androgenetic alopecia?

There is no direct clinical evidence that creatine causes or accelerates androgenetic alopecia. The 2025 trial that measured hair parameters found no differences compared to placebo.

Does creatine raise DHT?

A 2009 study observed an increase in DHT after 3 weeks, but the 2025 trial found no relevant changes in DHT or hair parameters compared to placebo.

When is telogen effluvium, hair loss, noticed after a change in training or stress?

It usually starts 2-3 months after a trigger and is usually self-limiting.

Is Hair Boost useful even if I take creatine?

Yes, because its goal is not to counteract creatine, but to support the follicle/fiber during demanding stages that require specific nutrients in addition to energy. The most important combination is with good habits (energy, protein, sleep, recovery).
