If you're keen to try a few products before forking out for a full sized one, try pm'ing kathymac or check out the swap board. I spoke to her awhile ago about sending samples over here and although she hadn't done it before was willing to try it. With the package size she could send you could get a decent collection of samples and if i remember correctly it was a decent price. She use to have a list of what products she had and what sample sizes they came in, i think on the swap board.

ps alannah..that sucks about the one-c hope ur still enjoying your self made conditioner. I was reading the long hair community discussion boards and come across snowy's moisture treatment (SMT anywho not sure if i've written it right) which is basically, honey, aloe gel and conditioner but people swear by it. I'm thinking i'll give it a go soon.
