Male Baldness Info

Hi. I’m a 24-year-old female with long hair using 5% Rogaine foam for mild ‘male’ pattern baldness. I have two usage questions.
1. The instructions say to “massage” the foam into your scalp after applying. I usually apply the foam by making 4-6 parts in my hair, applying the foam directly onto each exposed line of scalp, and then massaging each section for 5-10 seconds. Is this enough massaging? How long am i supposed to massage the scalp?
2. I know that using Rogaine can cause some unwanted hair growth in women, so i’m careful to use latex gloves when applying it. But I’m worried about the Rogaine spreading even after it dries. If i put my dry, rogained hair on my pillow at night, and then my cheek rests on the same part of the pillow, can the dry rogaine residue be absorbed and cause hair growth on my face? What if my rogained hair gets into my face while i’m sleeping? Or is it only effective/absorbable when wet, right out of the can? I know that Rogaine mainly works by getting into your bloodstream, but I’m still worried about having Rogained pillowcases or garments right up against my face.
Please only answer if you have experience using rogaine or if you are a dermatologist/hair expert.
Thanks so much!

Hi, I’m a 20 year old male,
I’ve noticed that my hair is thinning all over but shows mostly on top of my head. (not at all like male pattern baldness) I wash my hair every day but my scalp itches alot and by the end of the day my hair gets really greasy and smells bad too.
is it possible that the itchy oily scalp is causing my hair to thin?? I’m really annoyed at this because I have no idea what is causing the thinning.
I understand there is always a chance that it is hereditary but in my family the men start losing the hair (not a lot) when over 50.
Thanks in advance.
