Suave Naturals and VO5 conditioners are inexpensive (only around $1 a bottle) and can be used as cowash, rinse outs and LI. For a leave in, just start with a pea size amount, rub your hands together before working through your hair. No real need for a separate product for a LI
Tressseme Naturals also work for many for these purposes. Not quite as cheap, but still really reasonable. I can get them on sale for $3.50 a bottle.
I used Avalon Organics as a low-poo, but it is around $8-$10 a bottle (however since I don't use it very often it goes a long way). Someone else may have a low-poo suggestion to throw in here.
