Reverse Gray Hair

[FunkeyMonkey]

Being able to reverse gray hair would be amazing.

Would this cover white hair as well? My hair is moderately salt and pepper and I'm only in my 20's. It runs in my family so I dunno if the genetic card would play here.

I am going to +1 this thread from 2012. Given the progress that has been made with the subs in terms of manifesting physical changes, getting rid of grey hair would be a fantastic target.

Could combine this with the other requested sub for hair loss - greying hair and losing hair usually happen together! Maybe a general hair health sub?
