2a or 2b and recs?

Started life out with very blonde, very straight hair. As I've gotten older it's become darker, and with each child I've had, it's become less straight. Now I'm trying to embrace the waves.

I'm looking for product recommendations and I'm also trying to determine whether I'm a 2a or 2b.

Current routine involves Shea Moisture moisture and smooth shampoo and conditioner, plop in microfiber towel to soak up excess water, Cantu leave in conditioning mist, Frizz ease air-dry waves styling foam with prayer hands, scrunch with microfiber towel.

I sleep with a pineapple top in a satin scrunchie and on a silk pillowcase.

Occasionally heat style (once a month at the most). No dye at the moment.

Would love to figure out less frizz and thicker wave "clumps"? Dunno what the word for less piecey/stringiness would be.

Thanks!
