Crochet braids are a type of hairstyle where hair extensions are crocheted onto a person's natural hair using a latch hook. The hair extensions can be made of various materials, such as synthetic hair or human hair, and come in different styles, textures, and lengths. The crochet braids technique allows for a quick and easy installation process and can be a great protective hairstyle option for people with natural hair who want to change their look without damaging their hair.
