Clairol Perfect 10 Hair Color Review

I loved the idea of complete gray coverage and color in 10 minutes which Clairol Perfect 10 Hair Color claims it can do.  Then I left in on for 10 minutes and while the color was pretty, the gray was right where I left it!  So the next time I tried 20 (I color every 3 weeks because the roots come in fast & furious).  Nice color again, but the gray was persistent.  So I tried 30 and that was the charm.  So couldn't I just use traditional 25-30 minute products?  No, because those I have to leave on for 45 minutes.  I have scattered gray and some of those come in wiry. I do like the way my hair feels after I use this product and it is easy to style which isn't the case with some of the other hair color options.  I like the gloss treatment which doesn't last for 6 weeks, but does condition well.  The color does oxidize regardless of which shmapoo I use (and I use only shampoos for color treated hair) and I wash my hair every other day.  The comb attachment is a joke if you have gray.  If you are just doing roots or changing the color of you hair, I suppose it can work well.  There is no lingering odor nor have I experienced any adverse reaction.  Given how often I color and that this product can usually be purchased on sale, it is a good value.
