What exactly is shampoo?

Most shampoos are personal care and hygiene products that are made for cleaning scalp and hair. When we go about our daily lives, our hair become dirt and oil traps and needs to be cleaned. Oil glands in our hair produce sebum as they do all over our bodies, and this oil is one of the primary contributors to dirty, smelly hair.

Furthermore, as your scalp sloughs on and peels, small pieces of it (aka dandruff) can stay in your hair and even end up falling onto your clothes and surroundings. The places we go during the day also make our hair dirty, especially in polluted urban areas. Lastly, the leftover residue in our hair from things like gels and other products can build up over time.

After a while, all of this build up can contribute to dirty, greasy-looking hair. Shampoos, therefore, are an essential part of keeping our hair and scalp clean. Many of them also contain ingredients that provide the healthy, shiny-looking hair that everyone wants.

What benefits does shampoo have for my hair?

As previously mentioned, shampoo is meant to clean your hair. They get rid of sebum build up, and help wash out chemicals and product accumulations. A good quality shampoo keeps your hair healthy-looking and shimmering.

However, these days the composition of shampoo has been updated to provide many more benefits.

For example, many shampoos available on the U.S. market are designed to hydrate your hair. Others are designed to help cut down on oil. Others still pack frizz fighting ingredients, and ones designed to straighten curly hair.

In summation, shampoo is a must-have hair care product. It cleans and fortifies your hair, keeping it healthy looking and soft to the touch. Every type of hair, and even every individual has different shampoo requirements. That is why there is such a varied range of products available.

What is shampoo made of?

This is not a one-answer question. Different products contain different ingredients. The ingredients of individuals shampoos allow them to be grouped into eight primary categories that we have laid out below.

The principle constituent part of all shampoos are what’s known as surfactants. These are what produce the foam and clean your hair and scalp. The rest of the ingredient list contains things like preservatives, acids, conditioners, scents, essential oils, and other active ingredients in things like anti-dandruff shampoo.

The below table lays out the 8 major ingredient families in shampoos, along with what each does:

Category Function Examples
Surfactants  Cleaning and foaming  Sodium lauryl sulphate (SLS), sodium lauryl ether sulphate and sodium lauryl ether sulfosuccinate
Conditioners Offset the dryness of the detergents, replacing part of the eliminated oils Diethanolamine of coconut fatty acid, lanolin, lecithin
Thickeners Make the shampoo easier to use and apply Sodium chloride
Acids Balance the pH Citric acid
Preservatives Prevent fungi and bacteria Methylparaben
Opalescents Create a pearly effect for dry and normal hair Derivatives of waxes
Essences and essential oils Perfume Plant extracts: lavender, rose etc
Active ingredients Enrich the product Vitamins A and E, keratin, collagen, aloe vera, chamomile

Despite a wide range of different ingredient options out there, all shampoos have a number of shared goals. They must rinse out effectively and make your hair cleaner than it was prior to application. They should avoid chemicals that damage your skin or mucous membranes. They should also, ideally, be as biodegradable as possible.

Choosing a biodegradable shampoo means that you can safely wash it down the drain without worrying that it is doing damage to America’s beautiful fresh water ecosystems and groundwater.

How does shampoo work?

Shampoo’s main job is to get rid of excess scalp sebum. This oil is produced by sebaceous glands all over our bodies. Sebum is a double-edged sword because it protects our skin, while allowing dirt to accumulate.

A shampoo’s surfactants are its cleaning agents, and help break up sebum from the scalp and hair, thus removing all of the accumulated contaminants with it. Soap accomplishes a similar task, but it tends to mix much more with our sebum. This is the major reason why you shouldn’t wash your hair with soap that is not intended for your scalp.

What are the different types of shampoos?

There are a wide range of shampoos out there with different properties, ingredients, and purposes. Over time, different manufacturers have come up with myriad shampoos to suit every hair type and texture, as well as for all different ages.

Some of the most widely used shampoos out there include anti-dandruff shampoos that help fight the common fungus that causes dandruff. Many new shampoos also feature a more organic ingredient list and fewer chemicals. There are shampoos specially designed for babies and their extra sensitive skin and eyes, as well as dry and solid shampoos.

How should you use shampoo?

As with any personal care product out there, you have to know how to use it in order for it to work. Below is a list of detailed instructions to ensure you are getting the most out of your shampoo. This might seem like something to file under “goes without saying”, but there are probably some things you didn’t know.

The first step is to make sure your hair is wet. Use warm water, but not too hot, or you risk drying out your hair. use a small, coin-sized amount of shampoo. Going overboard doesn’t give you superior results. Spread the shampoo evenly across your hands and gently work it into your hair and scalp with your fingers.

Starting at the roots, work your way to the tips of your strands. After you have thoroughly distributed the product throughout your hair, make sure you rinse it just an thoroughly. Take the same amount of shampoo and repeat the process. Following that, vigorously rinse a second time and then wrap your hair with a towel and dry completely.

How often should I use shampoo?

Everyone wants to have clean and well-maintained hair. You don’t achieve this by shampooing your hair seven days a week, however. It is actually advisable to not wash your hair too frequently, or you risk losing too much oil, and your scalp is under-protected.

There is not hard and fast rule governing how often you need to wash your scalp and hair. It depends entirely on the individual. The most commonly thrown out number is two to three times per week. People with dryer hair might be advised to wash less often. Those with especially oily hair, conversely, might need to wash more often.

What are the adverse effects of using shampoo?

Despite the vast majority of Americans using shampoo, they are not completely side effect-free. Adverse reactions normally happen when people don’t use their shampoo properly. Using too much shampoo, washing too often, or not paying attention to the needs of your skin (i.e. sensitive skin) are usually the culprits.

An irritated scalp and surrounding skin is one of the most frequently observed reactions. This is more often the case with shampoos that are filled with irritants like alcohol. Many people also report eye irritation from shampoos.

Shopping criteria

While shopping for a shampoo you need to have certain buying criteria in mind. In the below section we have laid out the most important considerations to keep in mind when purchasing a shampoo. This will ensure you are buying a product that makes the most sense for you, and is best for your hair:

  • Composition
  • Hair type
  • Desired results
  • Age
  • Illnesses or allergies

Composition

A shampoo’s ingredients is one of the most important features. The ingredients dictate how well it will work, what it will do to your hair, and delineate any potential side effects. It is paramount that you carefully analyze a product’s ingredient list before making a purchase.

Additionally, based on your hair type, you might be looking for a product that focuses on certain aspects, or delivers specific results. This might entail fighting dryness or oiliness, or combating flakiness and dandruff. you also need to make sure that what you are buying doesn’t contain any ingredients that are going to provoke an allergic reaction.

Hair type

Another key feature of any shampoo is the hair type for which it is designed. Based on this criteria, different shampoos contain different ingredients in order to accomplish certain things. You need to know what kind of hair you have, as well as what kind of hair you want to have before buying a shampoo.

For example, there are special shampoos for straight or curly hair. There are also products made especially for colored hair, that will enhance and protect it. Additionally, damaged, dry, dull hair requires a product that strengthens and nourishes it. At the end of the day, there is something out there for every hair type.

foco

If your hair is delicate or sensitive you should opt for something that doesn’t contain any salts or parabens.

Desired results

You also need to understand what you want your shampoo to do for you. Shampoos are made to clean your hair, but they do other things too. All of them are going to clean your hair, but many of them have other features you need to consider before buying.

For instance, you might be after a shampoo that helps combat frizz, or you might want one that increases volume and shine. If you have flat, dull hair, you likely want something that gives you both volume and shine. The list of options is nearly endless.

Age

Many people fail to consider how their age impacts the kind of shampoo they likely need. Children and adult hair have different needs. Children also have more sensitive skin, so they need products that avoid using some of the harsher chemicals that are frequently found in adult shampoos.

Such child-friendly products tend to have a pH more conscious of skin and eye irritation. They also frequently include ingredients that make combing and maintenance much simpler. Then there are shampoos that claim to be appropriate for all ages. These products often don’t consider the special needs of kids, so it is better to get shampoos that factor in age.

Illnesses or allergies

Lastly, you need to factor in skin issues, and allergies. Certain shampoos are even designed for skin conditions like dandruff, where the active ingredient is formulated to combat the fungal cause of this condition. Other shampoos are hypoallergenic, or have a neutral pH to avoid exacerbating allergies.

On the other hand, people with certain diseases or conditions might be more prone to suffering the potential adverse effects of certain shampoos. You need to be aware of these things when selecting a shampoo. Always get a shampoo that takes into consideration any condition(s) you might have to avoid problems.

Summary

In summation, shampoos are essential personal hygiene products. You need shampoo to get rid of sebum build up in your hair, but there are many other functions and features of shampoo than just cleanliness.

Correctly applying shampoo will help you maintain healthy, shiny, strong, fabulous, and of course, clean hair. A good shampoo also makes sure you are looking after your specific hair type. Modern shampoos are designed with all ages, all hair types, and all hair styles in mind.

If you want to control and accentuate your curls, then you are going to need a product designed for curl maintenance. If you want to repair damaged, dry hair, you are going to need something with that in mind. Do your kids cry when they get your shampoo in their eyes? Then something kid-friendly is in order.
