New user - starting up a regimen?

[Everest]

Hi there, my hair loss is currently at a norwood 2.5 and im 21 years old.
I've been reading up about revivogen scalp therapy and S5 cream.
I would just like to maintain what hair I have so I do not wish to go onto rogaine.

Would using revivogen scalp therapy + Nizoral be a good start on my battle against further hair loss?
