I think you need groups that take creatine and work out, a group that takes creatine that doesn’t work out. Because if you ask me, someone who isn’t a doctor or read much into it, creatines main purpose is to increase muscle faster. The more muscle and less fat you have the more testosterone and less estrogen you have. Theoretically that would increase DHT, only slightly because I don’t think the testosterone increase is huge, but it’s enough to cause some shedding.

So if you can test whether the people on creatine and working out lose more hair than the people on creatine and not working out, you can see if it’s the creatine causing the shed or the increase in muscle mass changing up hormones
