finasteride Preferable Over Ru Due To Simple Application? My Regime While Waiting For Cb.

[Grasshüpfer]

I'm 27 and watched my hair loss for three months now and it's time to take action.

I ordered RU, however I'm a bit insecure about applying it.
How big is the chance to over or under dose, depending on the penetration? How do you keep the fluid on your head?

Or should I start with finasteride and check if I get sides, before using RU?

Thanks for your feedback.
