5% Minoxidil foam - how often do you apply it?

Hello fellow hairlossfriends 🙂 I started minoxidil 5% foam three weeks ago after experiencing more and more balding on my head since I gave birth eight years ago (I hope it can still work at all…). At the moment I apply the foam (half a cap) every evening but I read that one should use it twice a day. So I wanted to ask how often do you apply it? Thanks a lot in advance ❤️
