I totally agree with this and with the comment about getting the right cut. I would add that advice to try limiting the amount of product you use and/or using lightweight products. I would apply only what you need to keep your hair moisturized.
Once your hair is dry you can increase volume by gently pulling out the roots using your fingers as a comb/pick (some people use an actual pick). If you choose not to diffuse it helps (me at least) to flip the hair upside down a few times during the air drying process and scrunching the curls upwards. All of these things increase volume very well. If your hair is naturally thin/fine you may need to finish with a hairspray to hold the volume you've created.
