THICKER HAIR

I bought a Rogaine knock-off product--Wal-Mart's brand--Equate. It was only eighteen dollars for a three month supply. My hair is a little thin, I want the thick lustrous I had as a ten year old--probably not possible but I'm giving it a shot. The only thing that worries me is are these instructions: Wash hands if you use your fingers to massage product into the scalp AND make sure hair is dry before going to bed.

If I don't wash my hands will I have hairy fingers? If I don't dry my hair before bed will my pillow get wet and then will my face come in contact with the wet pillow and then...will I grow facial hair?

I am ordering a Hijab just in case. Actually this would cover up the thinning hair too. And hey, if I looked like her I wouldn't care if I were bald. Okay, I might care a little. Okay a lot. Okay, I'm a little bit vain. So I guess I will continue with the Rogaine knock-off and just put up with the hairy fingers. And the facial hair? I have tweezers and know how to use them.
