Rubbing rogaine foam

[aim4hair]

Hi All,
When i apply rogaine foam i put it over nw6 area. I have my hair buzzed (grade 1 or 2) which makes it easier to cover the area. However, once i put the foam i rub it to my scalp till it dries which usually takes a minute. Is that OK ? Or should i just put it on and let it dry by itself ?

You're supposed to rub it into your scalp. The foam dries rather quickly. If you just let it sit it tends to get stuck in your hair.
