Basic colours like platinum blonde should be easy to find. But what I'm particularly looking for are bright blue and hot pink that doesn't fade to a different icky colour. Recommendations are greatly appreciated.
Wow, where can you purchase all of these brands? I have not seen them in the shops.
Many of them can be found online. Manic Panic has their own website, so does La Riche, although La Riche's Directions hair dye are best bought on eBay (you can only order in bulk on their official website).
I've decided on going with Directions, since they have the colours I want. Now I'm looking into a bleach/peroxide (since I have black hair).
