Minoxidil foam application by dropper

[usernamethis]

I have medium-hair and when rubbing the Rogaine foam with fingers, a lot of product remains on the hair and does not reach the scalp.

So to avoid that, I tried this - I pour the foam in the cap, after a while it settles as liquid at the bottom, I collect that liquid by dropper and apply it directly to the scalp.

is this method acceptable? I think it's more effective than applying foam with fingers.

i've used to use Rogaine liquid solution, but now in my location I can only buy foam.

thanks
