Rhonda - I ordered the straight version for medium to thick hair - it came with that and the wave shaping version. These are both creams, so perhaps the smell is only in the spray.
My hair is on the fine side, but I have masses and masses of it! Haven't used the free one, but I used the straight version for the second time today - no frizz. I have curly hair - used to have beautiful ringlets, but in my advanced age

, a lot of that turned to frizz, especially on the surface - underneath I have beautiful curls! I am currently thinking about letting my hair grow out a bit - when it's too short, the hair isn't long enough for the curls to complete, so it gets all "bent" if I let it dry on it's own. I'm looking forward to trying the wave shaping version when it gets a bit longer!
I'm seriously thinking about ordering a second set!
