Clairol Nice'n Easy Gray Solution006A Light Ash Brown

I used to love gray solution. I've used it for about three years and it covered my grays for a good amount of time (about 4 weeks). However, I don't know if the formula has changed or what, but I just dyed my hair last week and the grays are already popping through! So frustrating. I won't use it again.

This is the only hair coloring product I put on my hair. It never fails to look natural.
