I have dark brown hair(level 3). I wanted my hair to be like a honey brown. So I tried a semi permanent rinse yesterday [June 29]. My hair didn't lighten at all. I now know that i cant lighten with semi permanent. I didn't want anything permanent since I already relax my hair. But now I want to have a small strip of blonde in my bangs or somewhere underneath. So I'll be purchasing Clairol Born Blonde Creme Lightener, and Clairol Professional Premium Creme 40 Volume Dedicated Developer. (is that volume too high or too low?). How much do I mix together, and  what to do with my hair after I rinse the bleach out? Use a special shampoo or conditioner? I won't be visiting a salon just to have one strip of blonde. So I would appreciate all tips and instructions to help me do it on my own. Thank you all!! 
Okay, Now I know that I should get a volume 20 developer. But I need more info. Mix it, apply, wash with a purple shampoo to avoid yellow color, but what else? Use a conditioner?
