PSA to Canadians: Dollarama currently has L'Oreal's line of sulfate-free and (some) silicone-free shampoos and conditioners for $4.

Stock up -- I have been. Not all of them are silicone-free but I believe the rosemary shampoo, anti-frizz shampoo and anti-frizz conditioner are (although the conditioner has wax).
