Hair Ends Always Frizz, Solution?

My hair ends always look a bit untamed and even when the top of my hair is smooth, the ends would look dry and untamed. I don't have split ends which is why I opt to not cut them so instead I was wondering if I do a hot oil treatment with olive oil (from my kitchen) and apply it to just the ends of my hair. Then use Olive Oil's Replenishing Conditioner for my hair. Would this tame the frizz that comes on my hair ends? Advice and suggestion would be great!
