cream leave in conditioner

gee, i can`t remember if i`ve asked this question before or not but i am looking for a good CREAM leave in conditioner that i can use after washing and conditioning my hair. i have tried spray in ones but they don`t seem to work too good for me. I would appreciate any suggestions!
Also- i have been looking on the net at these cream leave in conditioners and it would be great (if you have used them) to tell me what you think:
Vital Nutrients Shine Fusion Leave in conditioner
Sebastian Potion No. 9
Phyto 7 Plant Based Treatment Cream(although kinda expensive for my tastes)
THANKS SO MUCH!:)
Oh yeah, my hair is collarbone length, dry, and wavy. It is thick overall but each strand is thin. It is somewhat damaged from the chin down.

What I noramlly do is just not wash all of my conditioner out. I wash it like 80% of the way out and leave a little on the ends---it seems to work for me. But what do I know lol :D

why is it bad to leave some conditioner in your hair?

I`ve never had any problems with leaving a smidge of conditioner in my hair...in fact, if I don`t, my hair is unmanageable---I do use a clarifying shampoo too though. I guess it depends on the kind of conditioner and how much you leave in. I have used the Clairol Renewal 5x leave in conditioner though---didn`t seem to work well for my hair.
