Frosting - bleach spots on hairline

Hi all,

I have medium brown hair which I just frosted myself last night with a caramel frosting kit.  It turned out much lighter than expected but I kind of like it.  The only problem is that I got too close to the hairline a few times and now I have these bleach spots..circles. I tried to upload a picture but it wont work, sorry.

Does anyone have any suggestions on what to do to get rid of them?  I was thinking of getting a box of dark brown hair color and just touching up those little spots....will that work?

Also, since I think there is a tad too much blonde in it now, can I put the cap back on an pull through a few strands and use the darker hair coloring to darken it up just a little bit while keeping some of the blonde highlights?

Thanks!
Lisa
