I'm your age, and have fine, dry hair, prone to wispiness without vigilance. I style with as little heat as possible, and tend to go with Aveda for both products and colour. The Pure Abundance range is effective. With colour, I stick to highlights rather than the dead hand of all-over tints, which can look rather crispy.
A once-a-week deep condition with warm olive or coconut oil is worth the effort, too.
