Flawless by GU products are considered "sulfate-free". When we speak of sulfates we are referencing anionic (negatively-charged) surfactant sulfates used in hair care products. Anionic (negatively-charged) surfactants, are typically used in hair shampoos to create foam and cleanse the hair of excessive oil and dirt. When washing the hair, oil is not attracted to water and is repelled, however oil attracts dirt. The surfactant in the shampoo is able to suspend the oil and dirt in such a way that it can be removed completely from the hair. Because the anionic surfactants and hair have a negative charge, the surfactant is able to remove the oil and dirt without leaving a residue on the hair. The downside to some surfactants is that they can take too much oil out of the hair, essentially stripping the hair of its natural oils and stripping artificial dye if present. Anionic sulfate surfactants fall into this class. Some commonly used sulfate surfactants are:
- Sodium Lauryl Sulfate (SLS)
- Sodium Lauryl Ether Sulfate (SLES)
- Ammonium Lauryl Sulfate (ALS)
- Ammonium Lauryl Ether Sulfate (ALES)
Flawless by GU products do not contain any of these surfactants in our shampoos, conditioners, or stylers.
Our Blow Dry Cream does, however, contain a cationic (positively-charged) sulfate derivative, Behentrimonium Methosulfate. Behentrimonium Methosulfate is derived from rapeseed oil (canola oil). Due to its positive charge Behentrimonium Methosulfate is not repelled from the hair. Conversely, it deposits onto the hair follicle to smooth it out. It is also used for detangling and assistance with "slip".
|Drying "short chain" alcohols||Hydrating "long chain"|
|Use||To help product evaporate quickly (speed drying time), help oil and water mix (emulsifier) and sometimes as an antiseptic.||Conditioning (hydration), helps improve thickness of product (viscosity) and helps oil and water mix (emulsifier).|
|Effect on Hair||Can be drying on some textures or in excess amounts. Many products such as hairsprays have minimal amounts which "flash off" before it can penetrate into the hair shaft.||Usually derived from Coconut or Palm Oils, they are very beneficial for hair. Used to add moisture by drawing water to the hair, they are used to add slip for detangling.|
|Common Examples||Alcohol (Ethanol or Ethyl Alcohol)
Isopropyl alcohol (Isopropanol alcohol)
