Ex Input:
This is a terrible product. It makes your hair crunchy and dry and rough to the touch and to make matters worse I got a light brown color which I did not order and I cannot return it to get a refund or replacement. Not happy with this product or service. Would not recommend unless you don't mind taking a gamble on it.
