I need some hair dye help.
I went to Sally's today and got some hair dye and developer. I asked the woman if I needed anything else and she said no (other than an applicator bottle). It's the L'oreal Feria Professional stuff. Are there more detailed instructions other than mix the needed amounts together and apply to hair? Is 25 minutes a good time to leave it?
What about afterward? Usually I just buy the dye in the box that comes with all the instructions and conditioner afterward and all that. I don't wash it with shampoo afterward, right? Just rinse the dye out and I guess use a conditioner? I don't want to mess up my hair.
