24 Real Women Who Are Changing the Face of Beauty on the Runway

The model: Christina Wallace, founding director of Bridge Up: STEM

Her story: Just this year, she founded a program that introduces girls and underrepresented minorities to computer science and the many career opportunities available once you have the proper skills.

Her look: "We wanted the hair to come off as if they could do it themselves," said lead hairstylist Ashley Hanna-Pisciotta from Mizu Hair Salon. Wallace's waves were kept soft with natural-looking texture. For the two-step version at home, use hot rollers. Place a tissue along the roller's surface (to avoid heat damage), and then wrap a one-inch section of hair on top. Release and boost with texturizing spray.
