Take down half of the left and right sides and left and right crown sections. Comb them out and re-wet if needed. Starting at the back again, comb a slice of the
hair that includes a segment of the hair below it for use as a guide. Hold the hair straight out from the head and cut the hair vertically. Follow as before, working from
back to front, first one side, then the other.
Next, free the top section and comb it out. Beginning at the front of the head,
comb a slice of the hair up from the forehead on both sides to assure that the segment
is centered on the head. Using the perimeter length as a guide, cut the segment
from the forehead back and repeat the process, working backward to the crown of the
head. (It is important that you comb the crown section straight up on both sides or
risk having a lopsided effect.)
Finally, take down the upper halves of the left and right sides and left and right crown sections. Start in the center back of the head and blend the lengths by connecting
the line of shorter lengths from steps four and five. Work back to front, one side then another. When completed, you can cross-check your haircut, by combing the hair
out from the head and holding it horizontally, and carefully clip away any protruding "corners" or segments that may have been missed.
Once you've checked the haircut thoroughly, style the hair as desired. The result is a style consisting of uniform layers.
Advice: Practice this hair cut on a mannequin before trying it out on a real person.
