Although you may not think it will work for you, I would give CG a try before you rule it out. Many of us have been conditioned (
I am so clever)to believe that shampooing everyday/frequently is not only goos for the look of your hair, but for your health/hygiene. Honestly, it may work for some but I think it is a crock of poo.
I, too, believed I could never chuck the habit of shampooing, and even had the impulse to randomly shampoo my hair like a drug addict fiending..lol
If you are unsure, maybe you'd want to try a modified CG plan - for example, shampooing once a week while eliminating or at least great reducing products with silicones.
Some of my suggestions: Look for shampoos that are sulfate free. Just look in the ingredients and you will notice (usually) within the first couple whether there are any sulfates...You might have an easier time finding them in health food stores. A little goes a long way with shampoo, so even if you are spending..say $10 - $15 on a shampoo, you should be getting a lot of mileage..you really only need to shampoo the buildup off your scalp with at most a nickel sized amount.
I'm not sure what's available in Canada, but a lot of the curlies here like Suave conditioners if you're looking for cheap. I also like the Herbal Essences Body Envy Mousse and that would be good for you since you want volume and more curl at the root. I would also suggest getting a bowl shaped diffuser with fingers if you don't already have one - they are inexpensive and if you diffuse with your blowdrier upside down until its at least half way dry, you should get more volume and curl at the roots..
Hope this all helps and welcome!
Edited to Add: By the way, I hardly lose any hair anymore since I started CG. My hair doesn't get knotty - I don't even brush, I only finger comb or use a pick or wide tooth comb in the shower with conditioner in it.
