Do you work out?
If so creatine is supposed to help people push themselves harder and thus build more muscle. As a side-effect of intense exercises you'll create more testosterone. Increased testosterone leads to balding.
It’s not increased testosterone in general that causes balding, it’s increased concentrations/sensitivity of testosterone byproducts in the hair follicles. There is no correlation between testosterone itself and baldness.
The effect of creatine is measurable but in no way is related to balding.
Using steroids does have the effect. And a bunch of others, most of them unhealthy.
These things might look correlated as steroid ppl often consume creatine as well as some other things.
Sometimes when I see muscular guy with a head full of hair, I wonder what is counteracting that increased testosterone.
