How To Use Microneedle Dermaroller With Minoxidil Product?

[barkla]

I used Lipogaine minoxidil for four months. It helped stop my hair loss. But I haven't seen any regrowth yet. I am planning to use a micorneedle roller with Lipogaine.
Do you know how often I should use the roller? Should I use it before I apply Lipogaine or after? Should I use the roller each time when I used Lipogaine?
I see there are rollers with needles with different lengths from 0.25 mm to 1.5 mm. What is the best length of the needle?

I would like to know too. I'm probably doing it wrong. I dermarolled my head every time before applying minoxidil. My skin turns pinkish/red and the minoxidil stings a little. I do it for absorption, not wounding.
