The GHD styler is one of my personal favorites!
I use this tool on pretty much all of my clients, and I love that it gives a great curl!
In my opinion if you want great hair you have to be willing to invest some money.
There are many stylers on the market and most of them work great, but the key is to limit the damage to your hair. If you are using a styler that requires you to go over an area more than once then chances are you may want to think about investing in a better styler.
