Minoxidil foam or liquid + itchy scalp

[Henkeh91]

Hello!

I'm about to order more minoxidil but have some questions. I've been using kirkland liquid the past 2 years and it have worked pretty good until a couple of weeks ago when my scalp started feeling dry and itchy and I have some pretty bad shredding atm. The liquid minoxidil is probably the cause.

I'm thinking to buy the foam version from kirkland. Is it stupid to swap to foam from liquid (more shredding?) when I've been using the liquid for about 2 years or is the foam better than the liquid version?
