Neijae is one of the world's youngest barbers（理发师）． At just 7 years old， she completed training at the Junior Barber Academy．

    Neijae says she didn't think much about hair or styling before she heard of the academy， "I would braid（编成辫） my own hair and my doll's hair，" she said， "but I wasn't really interested in barbering course． I thought only boys could do it．"

    Her mom， Graham， says she tried to get Neijae's older brother to take the barbering course．When he didn't want to go， Neijae decided to give it a try．

    Neijae was the youngest student in her class． She was also the only girl． "I was never afraid，" she says．

    During the six﹣week course， Neijae asked her teacher a lot of questions． "If she needed to say it in a way that she could understand， she would ask right away，" Graham says， "She's not afraid to use her voice． She's not afraid to ask questions．"

    What was the most important thing Neijae learned from the course？ "Safety first，" she says．"That's always the first thing， Cleaning our tools， that's the second most important thing． I have to protect myself and my customers．"

    After Neijae finished the course， a video of hers became popular． Since then， she has had the opportunity to meet professional barbers and famous persons．
