What are some products that thicken hair rather quickly?

The right side and the middle of my hair is thicker than the rest. My edges aren't thin at all but I've always admired thick, full hair and want to achieve it.

I have been using Tropic Isle Jamaican black castor oil on my roots and scrunching to my ends after my wash and go routine and have found my hair to be much thicker!!
