Yes, they are small, I guess they are about 2 oz. but it's enough to use for a couple of days (even a week) to get a feel for how you like the products. Maybe because they are so creamy and thick they last longer. I used my sample of Spiral Curls Cream for 5 days before I ran out and I used a nickel size dollop for each side of my head.
[my hair type is a 2/3 combo with waves and curls and it's thick, coarse and prone to frizz. I look for softness, curl definition, volume at the roots, frizz control and shine in a product and even though I am not on CG I would prefer products without a lot of 'cones or protein in them.]
Hope that helps!
I had no luck with Jessicurl stuff either...
HG's: DEP Sport Gel or LA Looks Sport Gel - used over a leave in (alternate between moisturizing LI and a protein LI) and sometimes Giovanni LA Hold Hair Spritz
Method: Air dry 20 minutes, then diffuse for about 3 minutes for volume.
2/3 mix waves/curls - coarse, frizz prone, med. thick, porous, at-home color for gray, protein sensitive but I still need it sometimes, and I can't use glycerin in high humidity, NOT CG, wash with regular S&C 2x a week.
