Sandy's hair is still wet from the shampoo service when Hassan is ready to begin styling her hair. Based on their conversation during the consultation, Has-san knows that Sandy's hair will need to be about 15 inches long on the sides. How long should Hassan cut Sandy's hair?

Hassan should cut it slightly less than what is intended so around 16 inches or so.

Explanation:

The hair that is washed with shampoo is usually more voluminous looking and fluffy and it goes back to normal in about an hour or two.

This is something that barbers would keep in mind whenever they are styling someone's hair and only work in accordance with that.

As a similar thing has happened here it is the only natural way that Hassan would wash it and then cut it a little bigger than what is needed so when the hair settles later it is as much as Sandy needed.
