I am already taking a systemic approach with my diet...Just asking if this is something I could use along side?
I wouldn't expect much from topical cypro on your scalp. I think if you want to reverse you may want to look at pro-dopamine agents like adamantine. Some dopamine agonist drugs have been shown to return hair color to white hair in elderly patient. The minerals copper/zinc/selenium in abundant quantities from shellfish are probably the best prevention.
