It works. You can tell the barber your requirements when you go to pad your hair roots. Hair roots can only be padded inside. There will be a layer of straight hair outside. If you are afraid of seeing it, ask the barber to iron the flowers at the root of your hair a little lighter. But I must remind you of one thing. The padded hair roots will slowly straighten out. But this time is far less than the speed of hair growth. Generally, flowers have never disappeared before. The hair has grown. So pad the hair roots. From an aesthetic point of view alone. It can last for about two months. But it also varies from person to person. Be sure to communicate with the barber before you do your hair.
