Here's a photo of Didi---a great stylist in New York City. She really knows hair. She's holding an example of color #22R hair. The stock units come in 6" hair length--the ones she's holding are much longer and custom ordered. Professional stylists like to order the #22R stock units because it's a light blonde and it accepts dye really well. If a customer is in a 'pinch' and needs something quick she will pull out a #22R and dyes it to match the customers hair.
