“I have 4z hair and I have never in my life had an edge control work like this. I honestly almost gave up hope but decided to try this. I never write reviews -- this may be the first one I have ever written on a company website but this is worth it. This edge control finally gave me the confidence of being able to slick back my hair in those tight ponytails that I thought would never be possible for me. I am so grateful and I hope every girl out there with 4c/4z hair goes out and buys this because it will really make your life so much easier.”
