Girls and Makeup
There is a lot of money that females put into hair and make up. Their haircuts are not even really haircuts and they can cost 400% more than a barber for a guy. Instagram can be very helpful to a girl that wants to try out some new styles and they want to get opinions about make up and hair.
For makeup they will be able to get opinions from other girls that probably are not as friendly so be careful. But they really don’t want to buy a bunch of new makeup for their style and not wear it again after the first day of buying it. Sometimes it is good to get opinions before you head out looking like the living dead. Unless you mean to look like that!
