SO I got my hair re highlighted....it was highlighted before and had about 4 inches of roots. The bottom just seems a lighter blond now, like the highlights have lost their definition and just blend together to look like a blond shade.....does that make sense?? I am a natural neutral light brown color ( told a level 5?) I'd like to try to pull lowlight through myself in light brown....but I don't want it to end up an "off" color. Do I need a filler or will using a neutral shade of brown be enough ? I DO have a Sally's near so you can suggest anything there? I will just be streaking the lower portion with the brown but I just don't want to end up with green or grey or wierdo colors...LOL Here's a picture:

Any suggestions? I'd like my hair to have an overall darker look but not like totally going back to natural. Also, I'm starting to get mild breakage that makes my hair look fuzzy on humid days..what's good for this? I tried frizz ease and that just made me look like an oil slick....anything from Sally's good for this?  Thanks!!!
