Yeah I really think you will be ok considering it's your first bleach and redye. I didn't want to damage my hair so much but if you read the other thread started by me, "Hair test coming up - much more than a job at stake" you will see how important it is that I get as much THC out of my hair as possible.

That said, it is halloween in a couple of days so it's not the worst time to be looking like a halloween creature LOL

No seriously, you will be fine. If you reallllly think your hair is going to fall out just do a small middle section and see what happens. Bleach is much harsher than dye so in my very unofficial book, if you survive the bleach you'll survive the dye! Haha. Sorry its really late I'm being a bit silly.
