Most reviews i've read usually start with a shower. A majority of those include the provider getting in the shower as well. How does that work regarding their hair? i don't think wet hair is very attractive and i'm assuming they don't have time to blow dry, comb etc. So how does it work? Do they bust out grandma's ol' shower cap. i know it's stupid but i just got really curious while reading the reviews.

My atf simply puts her hair up in the shower or on the occasions that I get a room with a jacuzzi. Also, at my request, she doesn't wear makeup when she sees me.

I wouldn't worry too much about how to handle communal bathing, if and when it does happen.  FWIW, I've been seeing GFE types for about ten years now, dozens and dozens of great women, and probably half a dozen or less have actually asked or offered to bath with me.
Much like "I popped three times in an hour", "She begged me to fuck her" and "She had four O's while we were in mish" there is a fair amount of exaggeration that goes into many review process.

I sort of make kinky fun out of it.

"Why granny, what big boobs you have...."

It has become almost standard for the Asian providers to get in the shower with you and help you clean up.

I like it; it is very sexy and can really kick start a great session.

I didn't pay much attention to what the ladies did with their hair.  I was devoting all of my attention to other areas.

Maybe it's a carry-over from the AMP scene where they do the whole table shower routine...In any event I like the idea!

We are the pros at grooming.  I think we know how to handle ourselves and we can probably get ready faster than you gents.  Unless of course you decide to completely hose down her hair.

They all use a hand shower not a shower head.  The water goes where they want it to go and nowhere else.  Not too complicated when you think about it.

but have yet to find someone who wants to get her hair wet in the shower...

I think SI swimsuit editions for the past 30+ years may have something to do with it...
