I have bought a reborn subeta conditioner to make my hair a flame. How does it work?

It doesn't. lol.

You can use the Hair Salon to make your hair orange/red/whatever, or you can wear items like

I could be wrong, but I don't think the conditioner is a wearable. Are you thinking of Ember Locks?

Try going into your wardrobe, chose the option 'All clothing on Subeta', then click on Head. It'll show you all the wigs and such you could get. There's a few fiery ones.

damn... Well thx anyway^^ but what does it do then? Nothing!?

It doesn't do anything.

If you want to look up what an item does, you can use sites such as subetahq.com or subeta.neolodge.com

It's just a collectable item, like if you're collecting reborn items, or salon items or something. It can be added to galleries or pet treasures.

oh, ok. Thx again^^
