Query: A MESS!!!!

Don't waste money on this product! It's hard to apply and is like trying to wipe wet sand onto your hair. Little clumps will fall all over yourself and the floor, and if you have any tiny little irritation on your skin, WATCH OUT! IT WILL BURN LIKE FIRE! It's in my hair as I'm typing this, and I will have you know, the smell is so disgusting, I'm going to wash it out early! I can't take this horrible odor! I'd rather deal with being all grayed out by the age of 40 than to suffer through an experience like this again!!
