Understanding the Ingredients of Shampoo

The ingredients list on your shampoo bottle can be a confusing place. With names out of a chemistry book, it is often hard to understand what exactly you are putting in your hair. However, most of the elements of your favorite shampoo can be broken down into a few key categories. With a more complete knowledge of your shampoo, you can feel better about lathering up your hair in the mornings before starting your day.

Aside from water, detergents are the most common ingredients in shampoo. These chemicals generally fall under the designation of surfactants, with alkyl benzene sulfonates being the most widely used variation. These detergents are often cut with other, less caustic cleansers to help avoid a shampoo that is too abrasive to your skin and hair. Additional detergents, such as cocamidopropyl betaine, contain some fairly unique properties. This chemical not only absorbs static electricity throughout the day, but also provides moisture to your hair long after you are done showering.

Conditioners serve in many functions during and after the shampooing process. The primary use of these additives is to keep the hair and cuticle moisturized. Keeping the cuticle moist helps avoid flaking and irritation during your day. Additionally, since natural oils are stripped from your hair during the cleaning process, conditioners lubricate your hair to provide much needed protection. In some cases, the same conditioners are actually used in other household products, like fabric softeners.

Special ingredients in your shampoo are often added to help get that rich, luxurious lather feeling. While this process may feel nice and help you relax in the shower, it serves almost no practical purpose. A rich lather does nothing to enhance the effectiveness of your shampoo's cleaning properties. However, it does serve as a strong marketing tool. Few people are unable to enjoy a foamy and sudsy shampoo when taking a hot shower. Cocamide DEA is the most common foaming agent used in the shampoo production industry.

Outside of these items, many other ingredients are added to your shampoo for very specific purposes. Balancing agents are used to keep the acidity of your shampoo in line. Preservatives help avoid fungal and bacterial growth after your shampoo is produced. In some cases, salt is used to thicken the mixture and provide a better experience. However, more expensive brands avoid this ingredient due to the harsh nature of the chemical compound. The reason many shampoos look opaque and shiny is due entirely to wax. This additive not only provides and aesthetically pleasing look, but also helps your shampoo maintain consistency in the bottle.

The next time you are in the shower, it should be a little easier to flip over your shampoo bottle and figure out what exactly is going on in there. Understanding the ingredients found in shampoo can provide insight into a complex chemical process. From detergents that clean your scalp and hair to conditioners that protect, many of these items are vital to your hair health.

Some of the more intriguing compounds can be found right in your home. Table salt is used in many shampoos as a thickening agent. Other agents help create that rich and foamy lather that many desire. Although a deeper understanding may require a chemist, taking a few minutes to look over what goes into your shampoo can be a fun and illuminating experience.
