Gather sharp hair-cutting scissors, a fine-tooth comb, clips, a spray bottle, and a mirror
Wash and detangle your hair
Decide how much length you want to remove
Cut only a small amount at first
Work with dry hair for a more accurate result
Part your hair into sections
Clip away the sections you are not cutting
Comb each section straight before cutting
Trim little by little
Keep both sides even by checking in the mirror often
Cut bangs separately if you have them
Use point-cutting or small snips for a softer edge
Check the back using a second mirror or phone camera
Make final adjustments slowly
Stop if the cut starts to look uneven and recheck before cutting more
