Coloring my hair is pure drudgery

Gray hair comes along with the territory for folks in the Empty Nest stage of their life. I am fighting it every step of the way too. Admittedly, I am not an early adopter. I have been using Clairol Nice n Easy for many years.  But recently the foam in hair colors intrigued me.  And so I tried L'oreal's foam-in formula.  I really like it.  Coloring my hair is drudgery, but the foam-in method is less messy, a bit more fun/interesting because of the foam and maybe a bit faster.  I've used it three times now, and I am going to stick with it until something better comes along.

So, I guess you can teach an old dog new tricks. Now that I've covered my gray roots, What's Next?
