I used Sun-In, which is the devil, for years and years. Starting at like 7th grade b/c when you lay out it works better.
But when I started marching band I quit doing that even, b/c in the summers I was outside so much my hair just bleached blonde on its own. So I didn't have to do much.
But this year, sigh - I was in the mall and saw my old manager and she commented on how "i love your hair dark!!". I almost died!!! It by no means was dark, but lots darker than it had been in my whole life.
So, during fall semester of my senior year in college - I went to Wal-Mart picked up some Nice n' Easy...and ta da.
