Im a huge fan of mabic panic i just started using it recently, you have a reasonable amount of colours to choose from i chose the ulta violet colour. Any ways i highly recommend just like with any coloured dyes cover your area your going to use cover with paper towels or even news paper this stuff can stain so also chuck a old top on and some gloves. Now i didnt apply it straight to my hair i placed a little in a container then diluted it heaps with some conditioner, i only did this to make it lighter a was going for a pale pastely tone. If you are going to dilute it you can get a diluted pale white from manic panic and mix abit of the violet to it abit at a time til you like the colour i ran out of this so i had to opt for the conditioner mix it does the same but if you do this way make sure the conditioner you use is free of oils and silicone. Swarzkopf and tresseme have a range of these conditioners. Anyways after ive diluted it i section my hair into fours so straight down the middle apply it from top to the back on my roots then split and section from the top of my head to my ear i then apply it to my roots in this then is in four sections i then carry on applying bit by bit in each section making sure its really satured once im done i do go ask someone for help just in case ive missed a couple bits then i leave that from 30mins to an hour. Like after dryed styled and admired the colour the like i mentioned i was going for a pale look and i cracked it lol but yeh im a huge fan because the size of the pot im able to do this look a few times if i use conditioner as diluter but im definitely going to buy this in the future.
