Hello, ulta's website ingredient list does not show any silicones in this conditoner, however, Matrix website ingredients does, it shows AMODIMETHICONE. can someone please let me know if this conditioner does or does not contain any silicones. Thanks
- Asked by KK
- Official Answer By Matrix - Brand EngageHi, thanks for your question. Amodimethicone is a silicone, used in some hair products for shine, softness, and texture. Scientific evidence doesn't suggest silicones negatively impact scalp health or clog pores when used appropriately. To identify silicones in our products, look at the ingredients list on the packaging. They can be found under names such as DIMETHICONE, CYCLOPENTASILOXANE, DIMETHICONOL, PHENYL TRIMETHICONE, AMODIMETHICONE, and CYCLOMETHICONE.

Amazing
Hair Type Wavy Hair
My hair dresser got me hooked on this. My son and I both use it. I have wavy hair ,and my son has curly hair . Our hair is so soft now ,and easy to brush, and style . I have noticed less hair is falling out now as well . I'm super hydrated . I bought the heat protecting spray to . So happy I found this line because I have tried so many brands and this is the best.

Chef's Kiss
It's FANTASTIC. I highly recommend this for coarse, frizzy and heavy hair. It smooths it out and smells GREAT.
LOVE
This conditioner has become a holy grail for me! I have naturally wavy hair that doesnt typically cooperate with me and using this DRASTICALLY cuts down on my frizz. Also makes a huge differnece in the static level of my hair during the winter!
