Not proven: the entire claim rests on one small study showing creatine raised DHT slightly - hair loss itself was never measured, the rise stayed in the normal range, and no later trial has shown creatine users losing more hair.
The balanced position: with strong genetic susceptibility and active recession, skipping it is a reasonable precaution but a judgment call, not an evidence requirement. If hair is changing, check the usual suspects first - genetics, stress, diet, and the anabolic steroids that clearly do accelerate loss (often stacked with creatine by the same users, which may explain the reputation).
What to do
Common questions
Does creatine cause hair loss?
The evidence-based answer: not proven - and the claim is thinner than its reputation. The entire worry traces to ONE small study (rugby players, 2009) that found creatine supplementation raised DHT levels - the hormone behind male pattern hair loss - by a measurable amount. Critically, that study never measured hair loss itself, no participant was followed for hair changes, and the DHT rise stayed within the normal range. In the years since, no trial has shown creatine users losing more hair than non-users. The balanced position: if you carry strong genetic hair-loss susceptibility (family pattern, already receding), a DHT-raising supplement sits on the same side of the ledger as the loss - some men in that position choose to skip it as a precaution, which is a judgment call, not an evidence requirement. If hair changes are happening: look first at the usual suspects - genetics, stress, diet, and the anabolic steroids that DO clearly accelerate hair loss (and are sometimes stacked with creatine by the same users - which may be where the reputation came from).
