None of them, and I can tell you why.
Back in the end of 2003, I loved the Lustrasilk Aloe conditioner because it provided me with slip, softness and sheen (reccomended by Peachtree herself). I loved using it for conditioner washes and deep conditioning alike. Loved it so much I only used it for "special ocassions." I didn't even care about the mineral oil content.
At the end of 2004 I purchased another jar of this stuff and noticed that it was a new formula... with new ingredients. My hair hated it. Left it coated, matted, tacky!
I sent some PM's to another member who loved, then hated Lustrasilk. I hated the new formula so much that I wanted to contact the owners of the company via email about it, but they didn't have any information on the jar about an email or web address. I just had to give them a piece of my mind
So I did my research. I remembered that Lustrasilk was a subsidary of Gillette Company (the razor people, based in the US and the UK) so I went on Lexis-Nexis.com and looked up both of their financial/board of directors information. Found out that in the beginning of the 2004 fiscal year, they pretty much fired over 26 of the board of directors and 10 of their top chemists (that's why the formula changed).
So Den, if you buy the NEW formula and hate it, maybe you can look for the old one.
Sorry if I was so long-winded
