I bought the Infusium 23 Moisturizing 3-minute treatment after seeing it in Lucky and it rocks! My hair is really fine but it doesn't weight it down at all, its just soft and shiny and I have hardly any splitends. I highly recommed it if you are looking for a cheap ($6!) but great conditioning treatment.
I love their products! (Infusium). I have been using both their shampoo and conditioner for years and nothing has worked as well for my thick, unruly, fizzy hair as this stuff has.
Buuuuuut...i havent tried this new treatment. I'll have to go check it out tonight!
