So i took my grandmother in to the stylist today for her weekly fix. And was talking with the stylist (she has been cutting my hair also for about 20 years) about the hanging hair test. And she reaches under one of the cabinets and brings out a sack of ponytails. Then puts a samples of 3 different ones in sandwich bags for me to take home and put on my workbench!
There is some blonde, dark, and red hairs of different thicknesses.
Now i just have to explain to my wife why there are 3 different womens hair in my shop ;)
