My hair is natural (3c/4a) and bra strap length in the back - to my boobs in the front. I'm getting micro braids (maybe micro twists?) and I need to know: What type of hair should I use? Synthetic or human? What brand of hair is the best for micro braids/twists? How long should the hair be? (I'd like all my hair braided w/the fake ends loose, either straight or with a slight wave, but I don't want to look ridiculous. Keep it gully, do you think that would look over the top?) I plan on keeping them in for a month, possibly a little longer but I'll be surprised if I can make it to 2 months since I'm not sure how bad the frizz will be. Any advice will be greatly appreciated since I haven't had braids w/hair added in for over ten years.
