Revivogen scalp therapy - Do you leave it over night?

Revivogen scalp therapy - Do you leave it over night or does it work like shampoo?
Can you use together with retin a and minoxidil at the same time? It says on the homepage to wait for 3 hours but is this needed? Can't I use them at the same time?
If I want to good effects of revivogen - do I only need Revivogen scalp therapy?

you can leave it in overnight and that's probably the best way to use it - otherwise it leaves your hair looking slick and greasy during the day and has a mild smell about it.

They say you can use minoxidil with it no problem.
