When I was an apprentice, the makeup artist was always in a daze and didn't know how to practice my hairstyle. Seeing the customers coming, I was scared to death and didn't dare to start styling them. Not because I can't curl my hair. The hairstyles taught by teachers are all universal, all of which look good on the heads of fake models and are often recognized by teachers. Even this is useless, because the model is dead, the model's head shape, face shape, hairline and so on are very standard, and it can control whatever shape you make on its head. It's different when it comes to real people. A real person's head is round and pointed, and his forehead is particularly high, which you can't imagine. I once made a model for a customer to see, and the back was particularly beautiful. As soon as I walked to the front, the customer's rugby-shaped head was immediately displayed incisively and vividly, and I was scolded at that time, leaving me with the sequela of not daring to send it to the customer.
