Crochet Braids also known as Latch Hook Braids, are techniques for braiding hair that involve crocheting synthetic hair extensions to a person's natural hair with a latch hook or crochet hook. Like the weave, the first step is to cornrow your hair and then follow up with applying extensions. However, the difference is that the hair on crochet is loose hair or pre-looped braids and it is looped under the cornrows with a crochet hook and fortified with a knot.
