We have 3 suggestions that i can see:

1. Craftable Individual Color 1 time use Rare Hair Dyes
2. Rare ingrediants for the dyes
3. Requirements for having certain hair dyes work on you.

So as it stands, if we do all 3, we will have hair dyes that will be uncommon/rare, and have the extremely notorious colors have pk, karma, fame, or other requirements to wear.

Sound ok to everyone?
If not, discuss what parts you want to alter.
