EDIT: This color faded faster than any dye I have ever used in my life... I only kept 2 lippies because the intial color was great. I will use it again for an event, but never for an actual color job.
Add so much shine. Good strong color (i used dark brown). A bit drying, but the color/shine is worth it... I deep condition anyway, so it shouldn't be that big of a problem.
