Well, this took me a while to actually get to, but...in essence, this is an upgrade of my earlier topic regarding Subeta Shampoo/Conditioner, I'm not going to copy that post into here but there's quite a few items in the Grooming Parlour that aren't wearable that really should be. So, my ideas on them and such, mostly in order of oldest to newest item. (There's quite a few nail polishes which do nothing, but they're obvious enough what they'd do that there's little point putting them here. Also, I don't have /every single unwearable item/, I don't have ideas for absolutely everything, unfortunately.)

These shampoos could give hairstyles similar to their respective pet's head, coloured as common, perhaps with the ears, too.

There's quite a few possibilities for this one: -luxurious purple hair -a purple perfume-esque effect -purple sparkles

Since it's evil, perhaps dark designs around the eyes as well as what would occur with plain eyeliner? (this is one I'd be especially happy to sketch)

These brushes should probably provide hairstyles of a sort - alternatively, they could be held. If hairstyles, the bristle one could be short, layered dark red; the combo one could be dark blue with short hair on one side and long on the other; the chibi one could be long and fluffy golden hair.

These could be used as hair ornaments - of course the bloodred one would be dripping at least a little, and the dark matter one would have tiny little dark matters around it.

Perhaps this could give luxurious platinum hair, with long parts resembling a Sheeta's ears.

These mirrors could give basic eyes/lips matching the mirror's colouration.

Meanwhile these mirrors could have more drastic an effect - the graveyard one could also give stitches across the face and gaping eye sockets; the dark matter one could cover/replace the eyes with dark matter as well as giving an evil grin; the angelic one could give a halo as well as wings behind the head.

These could give a messy hairstyle in their colouration with plenty of bubbles; Angelic could also give a halo.

Since Vanishing Cream is part of this set and makes the avatar, well, vanish, why not have these creams be smeared over either the face or whole body? Making it, of course, the same colour as the cream pot. It could be just a straight colour change on the avatar or more clearly cream.

Yellow fangs. That one's easy to sum up.

A mohawk similar to a Hikei's mane, perhaps that becomes strands akin to the tail at the end?

Perfume effects - well, of course - in their respective flavours.

Long, straight hair in the respective colour, perhaps with a rose adorning it.

Medium, wavy hair in the shampoo colour, perhaps with streaks or tips of the label colour?

I can attempt a sketch at any of these when it's not ridiculous time in the morning, just ping me and I'll get to it when I can?
