Tressemme site doesn't have ingredients so I went to drugstore.com. Here's the mousse ingredients, but they don't carry the conditioner:

Water (Aqua), Isobutane, Hydrofluorocarbon 152a, VP/VA Copolymer, Polyquaternium 11, Propane, Polyquaternium 4, PVP, Polyquaternium 7, Cyclopentasiloxane, Polysorbate 20, Olealkonium Chloride, Cocamidopropyl Betaine, PPG 12 PEG 50 Lanolin, PPG 9 Diethylmonium Chloride, Glycerin, Gelatin/Keratin Amino Acids/Lysine Hydroxypropyltrimonium Chloride, Propylene Glycol, Sorbitol, Sodium Benzoate, Fragrance (Parfum)

Cyclopentasiloxane gives some people fits, but if you don't happen to be one of those, it's probably OK, especially if you occasionally low-poo. There are others that also have problems with polyquats - not that they're silicones, they just don't agree with some people's hair.
