One word of caution - if you are using the Loreal Excellence to go (their 10 minute color), count the time to apply into the 10 minutes. I know it's insane, but if you don't your hair will fry. I have thick graying hair, so it was a challenge for me to do the root application in under 5 minutes. And it wrecked my hair - I do NOT like this product at all and I have used the Loreal regular color for the last 10 years.
Good luck!
