heyyy haha, i know how you feel about dying, my hair was dark blonde practically till i was 14 and then i died it dark dark brown, it was crazy!!
here's an easy two step process that will get rid of the dye for you
1. take some baking soda and rub it on your skin with a little bit of water (it loosens the dye particles)
2. spray hairspray like crazy onto a cloth or your skin then wipe off
the dye should have no trouble coming off, sometime you dont even need the baking soda and the hairspray can take care of them
i have to dye my hair brown once every 3 months and ive had brown spots all over my forehead and this ALWAYS works!
