I get them too. It used to be just one on each side but I get a lot more now in the back under layer of my hair. I like them, but I never know if hey will show up. I have noticed that if I wash and rinse my hair standing up, they don't show up. If I flip my hair forward and rinse upside down, I tend to get a lot forming over the course of the day.
2b/2c ( weather permitting - 3a), fine texture but lots of it, colored and highlights, BSL.
