Turned my hair purple
I purchase this as it was recommended by a beautician to bring out the grey/silver.  I've used it 3 times.  Luckily, my favorite color is purple because my grey/silver hair is now turning purple.  The more I use it, the more purple my hair becomes.  On the bright side:  My coworkers did compliment me on the purple highlights in my hair.
