Great product !! He completely repair damage my hair at the base .jai long hair very dry and frisee, they are now smooth, soft and shiny as ever. I took the risk to do it alone, I figured quickly exhausts (4h) and I admit I botched the job and yet the result is smooth .my hair is just drying the hair dryer at me (not stiff either ... not dream !!) and I just spend 5 min plate has 180 ° and the result and gorgeous. Thank you amazon
