HAIR CUT TIPS: •Contour the cut. See Channing Tatum (left). Go shorter on the sides and longer on top. •Do the math. Electric clippers are ﬁtted with guards dictating how close they cut. A No. 1 is 1/8 of an inch, a No. 4 is 4/8 of an inch, etc. Go with, say, a No. 3 on top, a No. 1 around the ears, and a No. 2 in between.
