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...
Gel: BRHG mixed with Aura Naturalle Gel or B&A Gel
LI: GVP Conditioning Balm or Giovanni Smooth as Silk,
Organic Virgin Coconut Oil (as a DC, before and after dying grays, and like a serum on dry hair)

Method: Air dry 20 minutes, then blow dry for volume.

2b/c mix waves/curls - coarse, frizz prone, med. thick, porous, at-home color for gray, protein sensitive but I still need it sometimes, glycerin-sensitive (I think) in high humidity, mod-CG routine.
