I am thinking of coloring my hair again. Right now it's a beautiful cranberry color,but I've been thinking of highlighting the front part some more. I want a summer color. I learn the hard way that locks are very sensitive to lighter colors and even after you have washed the color out, the color can cause degeneration of the locks. I take great care when coloring; I try not to overlap on the color which can cause weak spots. I would suggest that anyone coloring their hair in light like light blonde should use color instead of bleach. Bleach can cause locks to "pop" or pull apart like straw.
If you use semi permanent colors I found that Avatar is very good,and it doesn't fade fast at all. Great for relaxed hair too!
