I recently purchased Kera Color Coloring and Clenditioner in copper. I have been looking for something different to do for my hair. Its been looking dull and dry lately. So I purchased this and I love it! It's really easy to use. You just shampoo your hair and then comb it through wait 3 minutes (up to 20 depending on the intensity you want.) then rinse. I used it twice to get the color I wanted. I love it! It washes out in 7 to 10 washes so it's not damaging to your hair. You can also put it on dry hair if you like for touch ups. I highly recommend this product.
