Start with clean, damp, detangled hair
Section the hair into four parts
Decide how short the shortest layer should be
Comb one section straight up from the head
Hold the hair between your fingers at the desired length
Cut straight across for the first guide
Use the guide to cut the remaining hair section by section
Keep the tension and elevation consistent
Cut small amounts at a time
Check both sides for evenness
Blend layers by point cutting if needed
Trim and refine the ends
Dry the hair and make final adjustments
