Drug testing companies claim that cocaine can stay in your hair follicle forever, or until it grows out and you cut your hair. Most tests only go back about 90 days. However, I have learned in my pharmacology class that hair tests are notoriously inaccurate.
Cocaine will stay in your hair follicles for ninety days before it exits the body. Cutting your hair more frequently will not make it exit faster because cutting doesn't remove the follicle.
