Revivogen with Rogaine

[Salvatore]

I know that many hold products like Revivogen and Procerin with much scepticism. If one were to experiment with either using a regimen including rogaine or Xandrox, what is the best method to apply these treatments? In other words, how long after rogaine should one wait before applying another solution?

Thanks in advance

When I was using multiple topicals, I would apply them at least an hour apart, preferably two or more.
