do you mix everything together in the box except the conditioner? Developing creme, permanent colour, and aromatic aura?

ya...but feria is strong it used to put burns in my head

If you are planning to use Feria on your hair, be very careful. It can make your hair an unpleasant shade or even burn your hair and scalp.

it worked for me

Feria, for some reason, is the hardest hair color to get out. So make sure the color you apply is the color you want. It stays in place very well. It's a hairstylist's nightmare!
