First of all, this is no ordinary haircut. When you go to the barbershop and you say “I want to do this”. They won’t know how to do it and they will take the shot the same way they did when they cut their hair at barber school for the first time.
So you will need someone who understands what you want. You need a Stylist. If there isn’t a stylist at the barbershop, just a bunch of old-fashioned barbers, this won’t work even if they tell you it will be fine.
All you have to do is go to a beauty salon. It is natural for you to want a satisfying treatment so that you still look beautiful and stunning. If you are a beginner, it must be awkward for you to go to a beauty salon. If not now, when?
There, they will wash your hair, prepare it for a haircut and then they will show you how to style or comb it so that you can get the haircut you want. It is very important to properly explain to your stylist what you want (shows the haircut image).
