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 and some 3A. Modified CG.
Highly porous. Color over grey.
Best 1st day method: Super Soaker
Conditioners: Curl Junkie Beauticurls Strengthening Conditioner,
Deep condish: Curl Junkie Curl Rehab
Stylers: Experimenting with cones & sulfates while the dews are high. Sometimes try roller sets - classic glamor but I prefer my curls.
Every day is a gift
