Unfortunately, hair loss is a possible side effect of all 5-ASA's. Most people don't get it, but it's quite a problem for a few. I'd agree that trying the biotin couldn't hurt and might help. Enlist the aid of a good stylist to maximize your thinning hair.
Unfortunately, pretty much all the drugs we use - Imuran, 6MP, Methotrexate, even Remicade show hair loss as a possible side effect. I don't know if a different drug would stop the hair loss or not, but the 5-ASA's have the fewest serious side effects of any of these drugs. Sorry I can't give you a better outlook.
