Shampoo Vs Soap: Which Is Better And Why?

by Shopify API on Jul 06, 2024


Shampoo vs soap are both used to cleanse the body, but some key differences are.

The shampoo is designed to remove oils and product build-up from the hair, while the soap is better at removing dirt and sweat from the skin. The shampoo is also more likely to cause dryness and scalp irritation, while the soap is less likely to cause these problems.

In this article, we look at the many differences between shampoo and soap and explore why both are used.

Shampoo Vs Soap: The Secret Ingredient Sodium Lauryl Sulfate

It's not soap, but what you may think of as soap isn't soap. A combination of animal fat or vegetable fat with an alkaline solution, a mixture of water-soluble salts and water, is often what you would call soap. Alkaline solutions can be found in nature, such as lye. So soap made from natural ingredients can be made.

Most soaps we use today are not made from natural ingredients. They are usually made with a surfactant, a detergent that makes it easier for water to spread and thoroughly wet something.

Shampoo Vs Soap The Secret Ingredient Sodium Lauryl Sulfate

The detergent you are using is technically a soap.

SLS is a common ingredient in shampoos. This is what makes shampoo foam up or lather when it's applied to wet hair. It is often the second or first ingredient in shampoos.

SLS is the same in shampoo and soap. The SLS molecules grab the oil and dirt from one end while the other attaches to the water. The SLS cleanses your hair and skin by taking the oil and soil along with it when it is rinsed off.

Shampoo Is Different From Soap

Although it may seem odd, bar soap was used to clean hair up until the 1930s. This all changed when liquid coconut oils were made available. This oil was able to liquefy soap, and eventually, a liquid soap that could lather was created (also known as Shampoo) was invented.

Bar soaps are no longer recommended for hair washing. Bar soap would leave behind soap scum if it were used instead of shampoo. It would be difficult to rinse the hair and scalp with hard water if you have it.

Shampoo Is Different From Soap

The shower gel is not recommended for hair. The percentage of surfactants contained in each product is something you won't be able to see from the label. Shampoo generally has a lower rate than shower gel. This allows the shampoo to rinse quickly from your hair. This also means less oil is being pulled out of the hair, which is essential, as we'll see below.

Hand washes also contain a higher proportion of surfactants. Face wash, which can be too costly to use as shampoo, often contains additional ingredients that clean the skin and prevent future breakouts.

Why Is There Such a Different Between Shampoo And Soap?

Stephen McNeil, University of British Columbia Chemistry Professor, said that if shampoo were only meant to remove oil, it would work the same way as hand soap. McNeil explained to NPR that shampoo alone, or SLS, is too harsh on hair.

Your hair and scalp make a thin layer of oil to protect them. The hair will remain shiny and smooth thanks to this oil. A detergent cannot distinguish between the oil in your hair and the natural oil you need to protect and shine. It gets rid of all.

Why Is There Such a Different Between Shampoo And Soap

You could wash your hair with soap only, but it would remove any oil or dirt. However, your hair would be dull, dry, brittle, and complex to style.

Therefore, shampoos that use SLS must repair any damage to the hair. They add conditioners to the formula to give your hair gloss and make it easier to manage. They can use natural oils or artificial chemicals to condition the hair.

Unfortunately, shampoo alone is not enough to protect hair from the harmful effects of SLS. Most people use a separate conditioner.
