Start with dry, styled hair
Section off the bangs you want to trim
Comb them in their natural side-swept direction
Hold the hair between your fingers at the desired length
Cut a small amount at a time
Use sharp hair-cutting scissors
Cut vertically for a softer edge
Angle the cut slightly downward toward the longer side
Check both sides for balance
Trim only the ends if needed
Recomb and reassess after each small cut
Stop before cutting too much
Blend the bangs into the rest of the hair
Style again to check the final shape
