Dark Matter Subeta Shampoo is currently an item given by Quentin's quests. I think it should be changed to a restockable item and moved to the Grooming Parlor with the rest of the Subeta Shampoos.

It makes no sense that this one item from the Subeta Shampoo line is given out by Quentin, yet the Graveyard one is restockable.

I think you're right, but I'm not sure if the staff will agree with this or not
