rogaine foam sticks to my long hair

[Gizmo]

hi
I put the rogaine foam directly on the scalp after I combed the hair aside, trying to avoid contact with the hair.

still, some of the foam gets to my long hair (my hair is a few inches long).
sometimes when I just comb it back to look normal (hey, I can't go to work with a "split hair" look...) the foam gets the hair around it.

this makes my hair look like it has gel on it, or is if it is wet, and making it look thinner.

what am I doing wrong?

after 10 hours, the stuff is still visible on my hair
when I touch my scalp with my fingers , I see grease on my fingers.
is all this normal ?
