I have fine hair, but a lot of it! And curly. I don't WANT curly. I read ever word of instructions and it still fried the ends of my hair and left it all over dry. I couldn't wait for my hair to grow out so the ends could be cut off (about an inch). Bottom-line.. this is not for fine hair. It can't take the strong chemical no matter how good your hair condition is. I have it TWO stars only because it did relax it some and with coarse hair maybe the product would work better. I won't do this again!!
