I second everything that Crimsonshedemon says. I apply Rogaine (I finally found a generic that I can open without difficulty so I use that) every night. I'm really lazy about it and sloppy and I just squirt the foam on my fingers and smoosh it onto the thinning areas. Then I wash off my fingers. (Don't want hairy fingers LOL). It works fine.
Good luck - I hope you find something that works for you.

Best 1st day method: Super Soaker

Stylers: Experimenting with cones & sulfates while the dews are high. Sometimes try roller sets - classic glamor but I prefer my curls.
Every day is a gift
