Manic Panic

There is this hair dye, really good stuff, called Manic Panic. It comes in a ton of bright colours and is semi-permanent, I've been using this stuff for years for all my hair-dying needs. (and believe me I have a lot of need in the hair dye department) :P

Here's their website:

You should check it out, common retailers of this stuff are Shoppers Drug Mart and Culture Craze stores. A lot of other "punk" type stores sell it. Usually runs about $10-$14 Canadian a jar and a jar will last for two dyes on short hair and one dye on long hair.

So far I've tried Atomic Turquoise, Cotton Candy, Electric Banana, Electric Lizard, Green Envy, Fuschia Shock, Infra Red, Enchanted Forest, Ultra Violet and Shockig Blue (I think) plus the Vampire Red and Tiger Lily Orange

The only one I've been disappointed in is the Vampire Red that was really more a fuschia and very quickly faded to a bright orange... but it may have been my own fault for dying over yellow hair, lol. The colours typically last about 3 weeks in people with normal coloured hair, but because I'm an albino and have white hair they usually last in my hair about 6-8 weeks.

Here's a list of all the regular colours they have... they also have some Amplified formula colours and some mousse-like all can be found off the main site, which I listed above.
