Debating on if I should get dreads or not..?
Forgot to mention: natural dreads do not harm the hair in any way, so if you take them out, you will still have your natural hair.
Twist & rip method dreads have a little damage done to them, but not much, you should twist loosely.
Backcombed dreads have damage done to the hairs, it puts little breaks in the strands when forcing them up in the direction of the scalp. If you may take them out one day, I do not recommend this method.
Never crochet for instant dreads, hundreds if not thousands of broken hairs everywhere. You will never get your healthy natural hair back with this method. Never put in hook in your hair.
