I have medium blonde hair with really light and medium bronze highlights. I didn't want to pay to have my roots done, so I bought a bottle of this and tried it out. I love it! I put it in my hair at night with no heat and let it gradually do it's thing. I have gotten compliments, and the color compliments my skin tone. I have naturally oily hair so for me the drying out aspect helps me have a little more volume. If you're on the fence about getting highlights based on cost, go ahead and try this first... if you don't like it, you can always get it professionally done later.
