How to get rid of old lady hair

I have wavy, color treated hair. I deep condition every time I wash my hair. I also use a no-poo co-wash. I do protein treatments when my hair feels particularly dry. I also use leave in conditioner and let my hair air dry. By mid-day, my hair feels very dry on the ends (I have chin length hair), and the next morning, my hair feels so dry it’s like steel wool on the ends.What can I do to have hair that is silky and holds waves well? I live in Toronto, Ontario and I checked the water hardness here, but it is fine. Please help me.
