Well, thanks to these lovely long threads and a big batch of boredom, I ordered a bunch of stuff from Sally's.
I ordered 4 kinds of Lustrasilk (olive oil, shea/mango, aloe, herbal) and enough other conditioner to last me a couple years. Online specials and free shipping were too good to pass up. Plus I got some non-hair stuff too. Can't wait to try it all.
As for the problems with Sally stores, I never go in mine anymore. The clerks are either too busy yakking on the phone to help, don't know anything, or they try to sell me stuff with sulfates and silicones (even after I tell them I don't use anything containing those ingredients). I much prefer online shopping anyway.
My order is supposed to be here tomorrow so more experiments coming up!
