I've worn my hair in braids for close to six months once but most of the time I will leave them in two months. I always wore the human hair braids. My hair never locked and I have fine, thin hair that can easily break but I didn't have those problems. The thing is its how you care for the hair while they are in the braids. If you need to do small re-touches then do them. If you need to remove build-up daily, weekly, etc..remove the buildup-as long as you replace moisture. Also, it's VERY IMPORTANT to remove the braids carefully-I found that to be the most important step.
