I co-wash every day and I do moisturize, I feel I have to. If not my hair will get dry and brittle, especially my ends.
I never leave the conditioner in my hair, that doesn't work for me. I use butters such as mango/aloe/hempseed and seal with Coconut oil.
ETA: It shouldn't take more than 30 seconds a minute tops. I just rub it in my hands and slap it on my head. You don't have to coat every individual strand, just make sure you get it all over your hair. Pay extra attention to your ends.
