Here's a tutorial on how I do a braid out on a Full Sew-in Weave. The hair that I used was a human hair blend and I used the boiling water method. I recommend this method for synthetic and human hair. For Good Quality Remy Hair and Virgin hair, I would advise that you use a setting lotion, curl pudding or mousse then proceed to braid the hair and let it dry under a hood dryer or just let it dry overnight. I will do a tutorial on something similar to that in the future.
