It did what it needed to do. I bought this to act as an at home salon hair dryer. I was trying to lift my hair with Malibu CPR, and it helped so much. With my first round of Malibu, literally nothing happened. Now I'm a couple shades lighter. The heating purpose worked fast, it didn't take long for my hair to feel warm. And besides the itching from my chemical process, it was calming. I found that setting four was perfect for me. I love that it came with a hair cap, really helped. And the fact you can clean the liner separately is a bonus, that way I don't mix chemical treatments' residue. I look forward to using this product more often.
