I'm getting a sew in right now. I've been wearing wigs all year. My nape really suffered a lot from that so I went and bought Strength of Nature - Root Recovery products. That huge bald patch that I had near the crown in the back had filled in. I didn't think anything could help. I was trying to grow that spot back for the longest time. Boundless Tresses wasn't even helping. Stress really wreaks havoc on one's head! I still have a few coin-sized patches but I'm confident this product will continue to help me regain my lost hair.
