They say they prefer a natural look only because guys are very oblivious. They either think ''she looks good'' or they don't. They don't weigh up what she did to look a certain way. It's like when girls wear extensions and dye their hair. They guy wouldn't say ''I like dyed fake hair on a girl'' but when he sees the girl, if she looks better with it he will think she looks good. Also if you make an effort most days to do your makeup, have your hair neat and wear nice clothes guys will think you take better care of yourself.
I would like her to not concentrate on her makeup, because most women don't realize how good they look without, so if she just enhanced her looks with makeup instead of trying to get her looks from makeup, it would be so much more pleasant than throwing on loads of foundation and looking ghostly lol,x
