I think all new ideas are good. I made a roll in Xinchao, and my classmates said it was beautiful and the price was not expensive. We can discuss it with them. If you want to straighten it and not stick it to your face, it's easy. You tell the stylist not to pull it up from the root, but from the middle, and only apply the medicine once, otherwise the hair will be as straight as vermicelli.
Of course, smoothness is not the same as fluffy. Hair will be smooth after straightening and washing. If you want to be fluffy, you can try a tin foil perm.
Personally, I think the barber shop is not very good, expensive and not well done.
