Start with dry or slightly damp hair
Part the hair down the middle
Section out the front pieces you want to frame the face
Decide the shortest length you want near the face
Comb each front section straight down
Hold the section at a slight forward angle
Cut a small amount at a time
Use point-cutting for a softer edge
Match the other side for symmetry
Check both sides in the mirror
Refine by trimming tiny amounts
Blend the layers into the rest of the hair
Style the hair to confirm the shape
Trim again only if needed
