Make sure that your hair is dry. Wet hair can stretch by up to 45%, so it’s much longer when it’s wet. If you cut it while it’s wet, you might cut more than you intend. [1] X Research source
Your hair should be completely dry while you’re cutting your hair. You probably also want to cut your hair when it looks “normal,” or how it looks on a typical day. If your hair is unusually curly or atypically frizzy on the day when you cut it, you might be displeased with how it looks on a normal day.
