Make a personal connection with the client, you have the whole meeting to talk about her hair.
Kids, fashion, hair color, celebrity news, and other light topics are great to start. If you can’t find a common bond or something interesting and welcoming to talk about then consult the client profile. Maybe her friend (who happens to be your client) recommended you. Maybe she related a horor story from another salon. Maybe you have similar style tastes. Getting your relationship off to a more personal start will create a bond beyond the business transaction.
