I am the same age you are and 5 years ago I had to stop using hair dye. I was determined to find something so I went to the health food store and found Henna. It has been my choice ever since. Plaquenil makes my hair uneven in color with the sun and I have grey too. There is one you can use first strictly for grey, then about a week later I use the color I like. I have had great results, no more burning of scalp and it lasts me longer.
When rinsing it out it can be tricky but use baking soda and it helps to get the rest out. There are some good websites on it if you google it.
I know you may have to wait a bit after regular dye but maybe Anne that answered will have some good suggestions.
