Questions about Minoxidil

[BiqqieSmalls]

Hello -

I am wondering 2 things:

1. Can I use minoxidil 2% foam in the morning and 2% liquid at night? Does it matter if I switch the type of solution; foam / liquid?

2. Should I start using 2% first and then 5% later on in my joinery? Im only 21 and am a NW2.

Thank you!
