The historic view has been that once a bow has excessive string follow there's nothing you can do.
Some of are finding that doesn't always hold true. I acquired an old hickory flat bow that had a about 6 inches of string follow in the one limb it had been standing on in a drafty, moist shed for 30 years.
I steamed it straight, having nothing to lose, and it kept the new position to the point that the bow has no string follow now. I have shot it quite a few sessions and it's fins.
I have also straightened several finished bows that took to much set. Cooked them thoroughly with a heat gun while slightly reflexed.
BUT, how much string follow are you talking about? If it is a couple of inches, don't worry about it. Just shoot it.
