Nope, I'm growing & retaining my hair just fine with weaves. It really depends on how you take care of your hair with your install.
Besides, I feel Shima has a grudge against weaves because a lot of people believe her hair is a weave and thinks if she somehow eradicates the use of weave, that she won't have to keep proving her hair is real.
Hair will always grow, barring health issues, etc., but it's really all about retention. Saying hair can't grow with weaves is a stretch.
I respect her crusade, but claiming that a protective style that's proven to work for many doesn't work at all, seems a bit misinformed to me.
