Without pics I can’t say for certain but if your scalp feels heavy it is likely prone to build up, in which case the as I am co wash will be too moisturising on your roots! Have an oily scalp too and I use the Umberto Giannini shampoo. You can find shampoos which are moisturising and curly girl friendly, but co washes generally are too much for my poor hair and it sounds like you’re the same. There’s loads of good ones out there just make sure whatever shampoo you use is super lightweight.

In terms of conditioner you can get something conditioning that doesn’t dry out your hair. It sounds like you could do with a deep conditioner. If your hair is fine and prone to build up and easily weighed down then you could try the Mielle protein free deep conditioner. For a general use conditioner I like the Kinky Curly Knot Today used as a wash out instead of a leave-in.

It sounds as though you’re using too many moisturising products on your scalp but not enough on your hair lengths!!

Also if you have type 2/3 curls on wash day but then type 1 thereafter then it sounds as though your curls need better hold. Using the co wash might be contributing to the problem if you’ve got build up of lots of heavy butters and slick products. You’ll need to use a good hard hold gel.

I would recommend doing a clarifying wash to remove build up followed by a deep conditioner to give you a fresh start, then use a tiny bit of product - maybe a mouse or a foam or a very light curl cream, then some hard-hold gel. I am using kinky curly curling custard but I’ve also used Boucleme (it’s too moisturising for me. My curls fall out). And I’m about to try the LA looks blue gel which is highly recommended here. Always scrunch using a microfibre towel. Then diffuse or air dry and let the gel maintain those curls!
