This curling iron heats up very quickly and holds a curl and/or wave all day long and sometimes into the following day. I have fine hair that was never able to hold a curl of any kind without loads and loads of product but when I use Jose Eber's Pro Series 13mm Curling Iron Ceramic Barrel Ionic I do not have to use any product at all. I think the secret to this successful curling iron is the fact that it is a wand and does not have a clamp attached. The ionic formula of this curling iron leaves my fine hair undamaged and smooth. It creates the perfect beach wave and curl every time I use this curling iron and I have done all of my friends hair using this heating tool and they have all fallen in love with it just like I have. My friends and I all have different hair types and yet this curling iron is successful on all of our hair types. I recommend this curling iron to everyone girl and woman I know because it is so successful at creating the perfect wave or curl you want every time and holds the curls without any product.
