1) What happens if I leave braids in for too long?
Answer: Typically, if you leave it in for longer than specified, not only is there going to be a considerable amount of build-up (even if you do wash it every few weeks or so), but the new growth can cause your braids/twists to put too much pressure on your hair; that can result in breakage.
2) Can I reuse crochet hair?
Answer: Yes, you can reuse crochet braids. Loose hair on the other hand, may be a little tricky.
3) How often should I wash my crochet braids?
Answer: It's an elevated wash day but a very necessary one. In fact, washing your braids and or cleansing your scalp every other week will eliminate product buildup, sweat, dirt, improve scalp health and prolong your style.
