Crochet braids are a protective style where loose (usually curly) braiding bulk hair is crocheted onto your own real braided hair. This is done using a latch hook tool that can be purchased at most hair care or salon supply stores. They can be in many different colors, curl pattern, even straight hair may be used. I really love this style because you can your whole hair color and hide your natural hair underneath. The style can last 4-10 weeks, depending on maintenance.
