This is not good for your hair. Sure it will dye it but the damage that is being done is not worth it. Theres a reason your stylist asks if you have boxed dye on your hair before they do anything to it. Made my hair feel like straw.
This hair dye left my hair smelling and feeling amazing. I have a few gray hairs and it covered it easily and was so simple to do myself. I am so happy to be able to color my hair myself and it turn out this nicely.
