I would say if it sounds OK, leave it alone. Try a conditioner from a retailer that will let you return it if it doesn't improve anything. Maybe BestBuy or some local shop, or try one of the mail-order houses. Check their return policy first. You will probably end up paying shipping at least one way if you return it.
