You can sometimes catch Haynie wearing her small gold Mary Kay pin to classes. She makes a habit of asking acquaintances whether they've tried Mary Kay. Sometimes she hands out brochures to friends in the dining hall.
Because Haynie is not a certified cosmetologist, she is not allowed to physically touch clients but says she actually prefers the instructive method because it teaches clients how to use the products themselves.
"It's not like when you leave the beauty parlor, and you don't know how to do your hair to make it look the same again," she says. "You're helping other people help themselves."
In the end, Haynie says, more than the profit, this is the bottom line keeping her in the business.
But there is one more factor, she says: "You get to play around with make-up."
