Well I only dye/bleach it like twice a year. Usually I let it grow out to the point where it's like I've got 5+ inches of roots before I'm like "okay, I need to fix this!" lol.

I just read so many horror stories on the 'net about chemical burns from bleach. But they're talking about full-on BLEACH. Like, 30-40% mixtures, which I think would be labeled as "bleach kits", not "lightening systems".
