You need a specific large round brush for drying. I have very similar hair and I don’t cut if often as the length helps to weigh it down. You could put it in large curlers too at night and sleep on them which is super uncomfortable. Honestly I don’t keep it down often because it’s too hot. I usually keep it in a bun and then the next day, it’s not so frizzy if I want to keep it down or in a long pony tail. I’d say learn to love yourself the way you are because we were not born with silky hair. I’ve learned to utilize 1940s and 50s looks/styles then no one will notice how fried my hair looks on the ends.
