How often you should cut your hair depends on how healthy it is and how fast you want it to grow; it is totally up to your own judgement.
Normal hair grows anywhere from 1⁄2 inch (1.3 cm) - 5⁄8 inch (1.6 cm) per month. Most stylists recommend getting a hair cut every 6-10 weeks, meaning that if you cut off 1/4 - 1/2 inch, your hair should still grow longer
