Does Creatine Cause Hair Loss? What the Evidence Says

what it claims

The community suggests that creatine promotes or accelerates hair loss in predisposed individuals, due to a potential increase in DHT (dihydrotestosterone) levels.

The core of this concern rests on a 2009 study (van der Merwe et al., RCT) that observed an increase in DHT levels in rugby players supplemented with creatine, but this study has never been successfully replicated. To date, there is no direct clinical evidence linking creatine consumption to hair loss or accelerated balding in humans. The notion that creatine causes massive hair loss remains an extrapolation based on anecdotal correlations and theoretical hormonal mechanisms. Although DHT plays a key role in androgenetic alopecia, the causal link between supplementation and a sufficient increase in DHT to induce hair loss is biologically tenuous and unproven. The community here is highly polarized, favoring personal experience (testimonies of loss) to the detriment of available scientific data. In summary, the forum consensus contradicts the current state of research, which does not validate this risk.

Creatine is purported to be not only an asset for physical strength, but also a powerful lever for improving mental clarity, concentration, and overall cognitive abilities.

The idea that one can specifically target each phase of sleep (REM, deep sleep, latency) by selecting precise dietary supplements is a popular approach, though it is nuanced by research.

The buzz from a Monster Energy comes almost entirely from its caffeine (and the sugar riding along with it) — the taurine and the B-vitamin megadoses on the can don't add a proven benefit beyond that.

Extreme, prolonged sun deprivation — like months aboard a nuclear submarine — is exactly the scenario where routine vitamin D supplementation makes real sense: several studies on submarine crews (Royal Navy, US Navy) show levels drop markedly within weeks without it.

For women in their 20s: four basics are enough — omega-3, vitamin D3, magnesium glycinate, and a quality probiotic — rather than 15 supplements.

Creatine isn't just for muscle — at doses higher than the standard 3-5g, some reaches the brain and may support cognitive energy, especially under stress or sleep loss.

5g of creatine isn't enough, the claim goes: bumping to 10g raises brain creatine further, and a 25g dose counters the cognitive decline from sleep loss and the mid-afternoon energy crash.

After a year of daily creatine monohydrate: no hair loss, no kidney damage, the loading phase isn't necessary, and "special" creatine forms change nothing versus plain monohydrate.
