Review title is Works well, but hold your nose! [SEP] The product did what they claim it will without damage to my hair. I wanted to dye my hair back to my natural color which is about a level 6. But the color I bought was too dark. This color reverse did the job. The smell is AWFUL though! I washed my hair, after rinsing, TWICE and still couldn’t get the scent completely out. It was so bad I had to shampoo again the next day before I couldn’t get rid of the stench. It smells like someone permed their hair and then puked on it! I am happy with the results though!
