Amazing!
I bought this for myself but before using I ended up giving it to my mom who was leaving for FL for a month, so I am reviewing based on her opinion. I bought the blond but my mom actually has light brown colored hair.  She came home raving about it, how that it was the only way she could have gone 6 weeks without getting it colored somewhere down there.  I am going to buy one for myself now.
