I found this study and I thought it was interesting. Ray has said that grey hair is cause by accumulation of tryptophan and I posted some studies on that as well. The question is whether other drugs such as pCPA, dopamine agonists (lisuride, LSD), prolacting antagonists (cabergoline), serotonin antagonists (cypro, ondansetron, ketanserin, etc) would have similar effects?
It would be an interesting self-experiment to run for a month or two.
