I have 3c hair and seriously suggest that you give the Curly Girl Method a shot if you feel like you're suffering from excessive dryness - and just in case you've never heard of it before it's simply a regime that incorporates more conditioner over anything else for healthy, moisturized curls. It has literally brought out my natural curl definition (that same pattern you see when your hair is wet) without making me buy a bunch of hair products or spend hours in the mirror.

I don't want to sound like a salesperson or anything lol. Just google Curly Girl method and give it a shot.
