A new law went into effect this week that requires Minnesota cosmetologists to be trained in cutting and styling textured hair. Minnesota is the fourth state to enact such a law.

Research by hair education company Pivot Point found that 65 percent of people in the U.S. have textured hair, yet not every stylist knows what they're doing behind the chair with that type of hair.

Valencia Montgomery Johnson is a cosmetology educator at Aveda Arts and Sciences Institutes who testified at the state Capitol in support of the bill. She joined MPR News host Cathy Wurzer to talk about it.
