Are you using Tresemee Flawless Curls conditioner? If so, it is loaded with silicones, and if you are not shampooing, you can bet the silicone is building upon your hair, preventing moisture from penetrating the hair shaft. Dryness, frizz, and tangles are the result. Here are the ingredients for the Flawless Curls conditioner:
Silicone ingredients end in -cone, -conol, or -xane. An exception is if there is PPG or PEG in front of the silicone, the PEG/PPG makes it water soluble.
I'm sorry to say that you need to clarify with a sulfate shampoo that does not contain silicones. Most VO5 shampoos will do the trick, and can be found for under a dollar. Its important to read lables, sometimes companies are sneaky and change ingredients without warning.
, either the volumizing or moisture are silicone free, so you want to replace your Tresemee Curly line with a silicone free conditioner and just start over.
