From the perspective of glyph face, firstly, it is most important to soften and beautify the rigid lines. Second, increase the fullness of hair and solve the problem of high cheekbones. Let me tell you something carefully. I am an amateur barber. I hope you can comment on it. First of all, keep BOB's head shape, so that the whole head is duck-egg-shaped, but your hair volume is small, so you need a proper perm to increase it, and then there is the problem of face shape. The bangs should be combed down and cut into arched bangs, which are curved and smooth to the hair at the temples.
