Life Cycle Thinking LCT seeks to identify possible improvements to goods and services in the form of lower environmental impacts and reduced use of resources across the whole life of the product, called its whole life cycle.
Any business, even non-profit organisations, must earn enough money to pay its costs and to invest for the future. When we think about sustainability, we often think about activities such as reducing water, energy, waste and the amount of materials used. In this section we'll explore these activities. The cosmetics industry starts from a good position when considering social responsibility because it plays an essential role in everyone's life.
Cosmetic products sold in Europe are not tested on animals. This is true whether or not the product makes an 'animal friendly' claim. The cosmetics industry is committed to the search for alternatives to the use of animals. Industry's efforts are based upon five key principles outlined in this section. Palm oil and palm kernel oil are natural oils extracted from the fruit of the Elaeis Guineensis palm plant. In , the world market for palm oil and palm kernel oil was estimated to be approximately 60 million metric tons.
PFAS per- and polyfluoroalkyl substances is the term given to a large group of substances, with different properties. The phthalates make up a family of substances each with its own, unique, spectrum of properties, united only because they each have a similar chemical group somewhere in the molecular structure. Soaps and anti-bacterial hand wash are effective tools for protecting you from viruses that are very easily spread from person to person. Some of us wash our hair every single day, others of us less frequently, but how much do we know about what exactly happens when we use shampoo?
Do we know, for instance, what a shampoo is designed to do? Shampoos are designed to clean and condition your hair. Simply removing all of the dirt or soil from your hair is not enough for today's consumer. So let's look at the challenge that faces the shampoo. There are between , and , hairs on a typical head which can be of various lengths, shapes and styles.
This large mass of fibres serves to catch soil from the atmosphere and the workplace. Added to this is sebum, the natural oil that is released onto the hair at its base from the sebaceous gland of each follicle. As people wash their hair frequently sebum rarely coats the whole length of the hair fibres. In addition, hair sprays, mousses, gels etc. The main aim of the shampoo is to remove dirt and soil and then condition your hair. This is usually achieved by building the shampoo from two distinct types of ingredients.
The first are surfactants that are designed to clean the hair. Here it is important to achieve a balance between mildness and cleaning. The second group is conditioning agents that leave the hair easy to manage and prevent "fly-away" or static.
These have to be deposited onto the hair during the shampooing process ie. Also, they must be deposited at a level that leaves the hair manageable and feeling clean. The main ingredients are a blend of surfactants. It is unusual for a shampoo to contain just one surfactant.
Some are designed to improve cleaning whilst others improve lather and rinsing performance. All are chosen to be mild and not irritating to the eyes. Surfactants work by reducing the surface tension between water and the soil so that it can be "wrapped up" and lifted from the hair.
Surfactant molecules contain two distinct parts. First a polar head group that is attracted to water hydrophilic and second a fatty chain lipophilic that is attracted to the soil.
The fatty chains line up around the soil particle with the polar head groups attracted to the water. As the surfactant molecules surround the soil particle they eventually lift it away from the hair and disperse it in the water. Conditioning ingredients: These normally include silicones and fatty alcohols.
Silicones are well known for their lubricious properties and make the hair easier to detangle. They come in a wide range of viscosities from thinner than water through to thick fluids, depending on the hair type and whether it has been treated with perms or colours.
Fatty alcohols give condition and help to control static or "fly-away". Conditioning ingredients in shampoos are often uncharged, unlike hair conditioning products. This is because the positive charge on many molecules used in conditioners would interact with the negative charge on the surfactants. You would end up with a product that could neither clean nor condition. Functional ingredients: There is little point making a perfect shampoo if when you pour it into your hand it simply runs through your fingers!
All products, including shampoos, require ingredients to control their viscosity or thickness. Shampoos also require ingredients to determine how the lather forms and rinses away. Added to these are preservatives to prevent microbial growth. The shampoo may also contain additional ingredients for hair protection and strength. When exposed to the sun the hair, which has no natural means of repair, is partly protected by the addition of sunscreens to the product. Aesthetic ingredients: Besides colour and pearlising agents to improve the appearance of the product, perfumes are also added.
These go beyond just "nice smells". They create an holistic in-use experience that plays to other senses to make the shampooing process a pleasant and desirable experience.
The biggest innovation of the last 20 years is the invention of true 2 in 1 shampoos that give the full cleaning and conditioning of a separate shampoo and conditioner product. These have been so successful in addressing the needs of the consumer that virtually every modern shampoo now contains a large element of conditioning.
The original 2 in 1's were formulated using high viscosity silicones as the conditioning ingredients. These have now been surpassed with improved silicones and the addition of fatty alcohols. The shampoos are formulated for a wide range of hair types which each have their own needs. For example, normal hair requires cleaning and control. In contrast, coloured hair has higher conditioning needs. During colouring a very special fatty acid is removed from the hair surface.
The hair is made more hydrophilic and contains more negative charges causing more static. Therefore, coloured or chemically treated hair will need specially formulated shampoos that contain conditioning ingredients chosen to deposit on this more hydrophilic hair.
As we continue to unravel the specific needs of each hair type and style we will improve our selection of both surfactants and conditioning ingredients to make sure that the consumer gets the look they desire every time they wash their hair.

How do deodorants work? What about deep conditioning? Say it with me: deep conditioning is a lie. Deep conditioning is just regular conditioning plus time plus the tricks our minds play on us when we dare to hope.
It means that you could probably get the same effect if you used your normal conditioner the way you use a "deep conditioner" which, yes, deserves those scare quotes.
Does any "deep conditioning" actually work? Your basic coconut oil, as it turns out, has "just the right size and structure that it can penetrate into the cortex," says Schueller, and therefore it can protect hair from the inside out. One of the most damaging things for hair is a simple wash and dry it because the water swells the hair and messes up the cuticle.
Coconut oil prevents water from absorbing into the hair and so reduces the swelling damage. Just washing your hair is bad for it?
What do we know about air dry versus blow dry then? Schueller agrees that air-drying is preferable to blow-drying, but he also said that air-drying itself can also cause harm. That means more time for the water to swell inside the hair and mess up the cuticles.
The longer the hair is wet, the more damage happens. Since it turns out that deep conditioning is a lie, what else is a lie? What about protein treatments? Protein treatments are a mixed bag. The proteins basically work like extra conditioner.
They help form an extra protective layer on top of the hair and keep the cuticle smooth. And my hair did feel better after I tried this, though not for long. What about "purple shampoo" and color-protecting shampoos and conditioners? This is a topic dear to my heart because I just went out and bought a bunch of both.
To be clear, "purple shampoo" and "color-protecting shampoo" are different things. It has a consumer arm called Mother Dirt, which creates mists and sprays that preserve this bacteria. Mother Dirt also manufactures a shampoo. The company just thinks that the first step is not killing off the ammonia-oxidizing bacteria they think are important.
Weiss says that the team is looking into creating conditioners as well, but that there needs to be a lot more known about hair science.

When was the last time you trimmed your split ends or performed other maintenance functions on your hair? These are the things both you and your hairstylist are going to want to know before you make hair care and style choices. Once you have become acutely familiar with the hair you currently have, it is time for you to think about where you would like your hair to be in the near future.
If you are someone with short hair who wants to grow out your hair, then the shampoos and conditioners you pick will likely be centered around keeping your hair as nourished and protected as possible. Or perhaps you are ready to give a bold, new, outrageous color scheme a try. Your shampoo and conditioner will help lock in that color and restore the chemical damage done with dyes and bleaching agents. You may also be battling a natural disadvantage that makes your hair difficult to deal with.
These challenges can include nutrient deficient hair or a difficult texture. Whether your goal is a style overhaul or much needed maintenance, you are going to want shampoo and conditioners that help support that goal. This is especially true for products such as shampoos and conditioners that are used frequently. Knowing a bit of background on your products and brands can help you avoid some hairstyling setbacks.
Take time to learn how long your brand has been in business, who officially endorses it, the standard of ingredients and if there are any major scandals or consumer complaints. Your hairstylist will be able to take their professionally trained eye and their insider industry knowledge to assess your hair and make a trustworthy shampoo and conditioner recommendation.
We all get comfortable in our haircare routines. Additionally, we become familiar with our brands, products, and hair routine. These parts of our hair care routine become second nature and easy to forget about. However, it is good to re-evaluate the condition and style of your hair every once in a while. This will help you catch problems early and address them in less drastic, less expensive ways. Switching your shampoo and conditioner can happen when you notice a new issue arise, but it can also be time to switch, when you decide to take a new style adventure or change your hair in some significant way.
Sometimes these changes will be permanent overhauls, other times they will be temporary solutions to a singular issue. Regardless of the reason, it is imperative to your hair health that you know when you need the support of something different. There are more options of shampoos and conditioners than you might think.
This is shampooing and conditioning that the vast majority of us are familiar with. It works by cleansing and moisturizing your hair with two separate products a shampoo and a conditioner and completing each of those steps by rinsing the product out of your hair before drying.
