So far so good - the product is excellent. I can even do my hair as well as my hairdresser! My hair is really thick, fine with a kinky curl. The length is layers and longest part is near chin length. The rollers give me a completely different and polished look - smooth curl, volume and shine. Use of product with roller essential, light hair spray can be used. As day goes on the smooth culr loosens and takes on a great look.
