Start with clean, damp, detangled hair
Decide where you want the shortest layer to fall
Section the hair into top, sides, and back
Comb the top section straight up
Hold the hair at the desired elevation
Cut the first guide length
Use the guide to cut the remaining top layers
Release small sections and compare lengths
Cut side sections to match the guide
Blend layers by cutting vertically into the ends
Check both sides for evenness
Trim any uneven pieces
Dry and recheck the shape
Make small final adjustments if needed
