Welcome Lindaazure! From you pics it seems you are right - you look like 2a/b to me, but many people will tell you that your hair's properties (for example how porous it is) is more important in choosing products than the hair type. But I think hair type is an important jumping off point.

There is a special 2 forum that you might like to read up on. Best of luck with your journey to embrace your waves! I hope to read about some of your experiences.
2/c-3a Coarse hair med. density.
Protein sensitive but can use occasionally
Highly porous. Color over grey.
I love all the Curl Junkie products and use CJ CCCL as my main styler. Still hoping for 2nd day hair....
Every day is a gift
