The biggest thing you can do is maintain good water quality. What size is the tank and how often do you do water changes?
Doing water changes often, keeping the temp. at 80-82*F, and feeding a (good!)high-protein pellet all will help him rebuild his fins.
To answer your question, you can add aquarium salt for about a week to help with healing. Do you know how to add it without possibly stressing the fish?

Good, I would bump the water changes up to twice weekly 50% change. I do that for my 10 gallon currently lol.
