Corrigir erros de barbeiros raspando a cabeça

First of all, this is a clipper/buzz cut sides and back, like usual. This time though I notice some fails in the last barbers cut. Short winged top on the left and right. UGH! So this created a sloppy part line. I have to use my nails to dig up her fine little hairs to make it all lay correctly. Buzzing her with a #4 and then a clean up at the back of her head at the nape. Then around her ears. 6in long hair on top is left alone today.
