Review (5/5): Pink
Iroiro is my new favorite semi-permanent color line. This pink is very, very bright. It is a fairly neon shade of pink. It fades slowly, but it doesn't appear like it will be stuck almost permanently in my hair, like some pink dyes have done. It only bleeds when wet. I have noticed a tiny bit of pink around my shirt collars, but it comes out easily.
If you're feeling a little naughty, you can wash with warm water a few times and not have a drastic fade. I highly suggest using cleansing conditioner if you use semi-permanent colors.
