What is a good product to use to dye my gray hair?

I am getting some gray hairs on the sides of my head, above my sideburns and ears. They are now too many to pluck, so I'm going to have to dye them. I'm worried about dying them though because I don't want to buy a dye that is too light or too dark from the rent of my hair, which is light brown. How do I know the right color to buy? I've never done this before, so I'm kind of nervous.What is a good product to use to dye my gray hair?
Haha don't be nervous. My mom was just like you. Bring a trustable friend to the drug store (cvs, vons, target, walmart, walgreens) and go into the hair dye section. There will be swatches of hair on the racks and the corresponding product on the top. Compare your hair to the swatches and pick out the one that matches the best. Make sure to take proper care of your hair and use a shampoo and conditioner made for colored hair so the color doesnt start to fade and you will most likely not end up with to light or to dark hair.
