answer:A pair of scissors. Then, stop fucking with it. Only shampoo your head to the base of your neck, condition all your hair. Stop using heat and damaging chemicals, resist styling as much as possible. Your hair will eventually be lovely again. If you feel the need to really try and fix your hair, cover it in mayonaisse, wrap your head in a plastic bag or saran wrap, wait an hour and rinse. Allow to dry and get dirty again – go to sleep, the next morning wash and condition. Also, a **** rinse can make your hair appear shinier and smoother but the alcohol isn’t great for it if you do it to much. I did both of those in high school when I had ‘classic length’ hair. Once every two weeks, alternating treatments.
