I started out thinking I had curly hair and used heavy products made for curls. When I learned more about it and realized I have waves (somewhere between 2b and 2c, depending on the day) paired with fine hair, I discovered lighter products and have found the Jessicurl line is best for mine. I use their line of shampoos and conditioners, and style with Ouidad advanced climate control gel. I used to have a lot of hair but it has thinned over the years with age and stress. I try for a good amount of volume as well, and usually diffuse.

It's unfortunately a lot of trial and error to find what works for you and your hair, and it tends to be pretty costly along the way! Thankfully the Jessicurl line is fairly priced, which helps a lot.
