Before going the dye route, you might try using a very soft-lead artist's pencil on the emulsion side of the negative. Build up the pencil marks to match the surrounding density as best you can, or slightly darker. Obviously, a light table and good magnifier help.
Most of the retouching done in the days of "Hollywood Glamour" was done with pencils, I believe, so they could mass produce 8x10 contact prints without further retouching.
In my opinion, that for a novice this is not a great idea. For one thing with dyes you are on the base side of the negative not the emulsion side so you are not damaging the emulsion. The use of pencils way back, were on a different kind of negative and the people doing it were very well trained.
I would do what Donald Miller suggests.
