Title: Not for gray hair
Review: I put this in my mother's hair 3 days ago. Her head is entirely gray. When I flat ironed it after putting the product on, it turned a yellow-orange. We were hoping it would wash it but we washed it last night and it is still the same color. Her hair is soft and much straighter, so I feel the product does work. But, if you have light hair, I would NOT use this. We have not come up with a plan for her color yet.
