Customers are saying
Let me start by saying I’m not much of an extension wearer because I have been hard pressed to find a brand that carries hair like mine. When I opened the pack I knew that this hair was going to work. I love the texture, the ease of install, the length, the bounce, everything! For a clip ins first timer it was very simple to figure out and gave me versality that I didn’t know clip ins could have! I will definitely be trying more styles in the future
