Braids and coconut oil are two things my hair doesn't like, it always end up looking dry, never really "damaged" though. Are you sure it isn't just kinky ends from all the bending? Have you washed it again after this? I would wet my hair all over again and do a moisturizing treatment.
Also I don't think brushing out braid waves/curls always turns out nice, people prefer finger combing it only. Most wavies/curlies prefer to detangle with damp/wet hair, it's less damage for us.
