I totally color my hair. And I don't lie about it. When someone tells me they like my hair, I say 'Thank you. Loreal 4M!'
I don't do it very often. I usually wait until the roots are 3 or 4 inches long. It's not a major color change for me, just a little redder than my own. So I let it grow out. Then when I dye, I dye my whole head.
Apparently, yesterday afternoon I didn't rinse well enough. After a couple of hours my head was burning in a few places. So I rinsed my hair again. Wow, I did NOT rinse it well enough the first time. I was still washing LOTS of color out of my hair.
So, I have 3 spots that have obvious chemical burns. You can't tell by looking at my head, but I can tell when I go to scratch an itchy spot. YOW! Burn!
So, PSA: Rinse hair THOROUGHLY when you dye your hair.
