Can You Use Body Wash As Shampoo?

Many of us find ourselves in a pinch and need to multipurpose our body wash as shampoo.  Sometimes it’s when you hop in the shower only to realize your roommate used the last of your shampoo. Or, maybe you need to cut costs and want to eliminate an extra product. 

You can use body wash as shampoo, but you may not like the long-term effects on your hair if you do it consistently. Long-term use is likely to dry your hair and scalp. Those with shorter hair are less likely to notice the difference. For longer hair, try a combination shampoo and body bar for a 2-in-1 product. 

Read on to learn the chemical differences between body wash and shampoo. We will also provide suggestions for 2-in-1 products if you want to permanently reduce your product inventory. Consumers can choose multi-use products in both liquid and solid forms to 

Are There Any Differences Between Shampoo And Body Wash?

Given that body wash and shampoo seem to be of similar consistencies and scents, the differences are not initially apparent. The intense marketing and product pushing of the beauty care industry is well known. Ultimately, few of us would be surprised if the outcome was that there were no real differences between the two products.

Humans have lived millenia without separate soaps for different body parts, and shampoo is a fairly recent invention. This is actually an invention for the better. Body wash and shampoo share the same two primary ingredients – water and surfactants. However, there are important differences in both the ratios and the added ingredients in each product.

Surfactants Give You Suds

Surfactants allow the combination of materials that would not normally mix together, or only mix with a lot of effort. Surfactants are one component of detergents. Many ingredients do not naturally mix together; their molecular structure is incompatible. Surfactants reduce the surface tension between the molecules, allowing them to meld together.

Surfactants, among other things, give us the foaming that we associate with soaps, toothpaste, and other cleaners. There are many types of surfactants. The choice of which primary and secondary surfactant to use is an important research and development decision for every product.

Surfactants give us the satisfying lather that we associate with cleanliness. Greater amounts of surfactants create the foam more easily than lesser amounts. Ultimately, body wash usually has more surfactants than shampoo. This is because it is easier to create a lather with hair than with skin. Hair has more surface area and texture to create an easy lather.

When you use body wash as shampoo, you are applying more surfactants to your hair than is actually needed. This is fine now-and-then, but it is not ideal long-term. Shampoo uses a lesser amount of surfactants to avoid excess drying by removing less of the natural oils. Some oil is vital to hair health, which is why it is not recommended to wash most hair types daily. 

Shampoos Have Conditioning Agents

Many people use a separate condition for their hair, but shampoo itself also contains conditioning agents, albeit in smaller quantities. While the cleaning surfactants are negatively charged to remove excess oil or other debris, conditioning agents are positively charged. This means these molecules are meant to deposit rather than remove. 

Body washes also have conditioning agents to prevent your skin from becoming overly dry from product use. There are several types of conditioning agents, and some work better for skin, and vice versa.

For example, cationic surfactants are commonly used in 2-in-1 shampoo and conditioner but are rarely used in body wash. Emollients and oils are more commonly used in body wash but can weigh hair down, leaving it limp. These conditioning agents make your hair easier to brush out after washing and leave the hair shinier than if they did not exist.

Hair And Skin Have Different Needs

Hair and skin have different needs because they are of wildly different composition even though they are both on your body! Hair itself is composed of dead cells, which is why split ends do not repair themselves. Hair springs from follicles in your scalp, and hair healthy is impacted by scalp health.

Conversely, skin is a self-regenerating organ. The dead outer layer is repeatedly shed as regeneration occurs. The greater surfactants in body wash can ultimately cause drying of the scalp and dandruff, which will impact both the health and appearance of the hair. 

Some Products Are Specially Formulated To Be Both Body Wash And Shampoo

Now that we know that using body wash as shampoo is not a long-term solution, we can consider alternatives. It is absolutely possible to reduce the number of products in your shower. You will just need to search out products formulated to meet the needs of both the skin and hair.

Reviews generally indicate that a separate hair conditioner is still needed when using a 2-in-1 body wash and shampoo. Of course, if you are someone who does not use a conditioner each time you shampoo, you may not notice a difference.

Two-in-one products are usually most suitable for people with short hair. People with long hair can be carrying around individual strands that are 5 to 7 years old on the ends.  People with short hair will have ends that are no more than a year old, so much less care is needed to keep it soft.

You may find more success with 2-in-1 products if you supplement with an occasional deep. For regular use of a leave-in hair conditioner could also be beneficial.

Point of caution before switching to a 2-in-1

Keep in mind that if you suffer from sensitive skin, you may be quickly disappointed by the results of a 2-in-1 product. Your skin will react with noticeable intolerance before your hair.

Most popular 2-in-1 products

Given that 2-in-1 shampoo and body wash products are most successful for short hair, many of these products are marketed to men.

Jack Black All Over Wash – This higher-end product is marketed for hair, face, and body. It is geared for sensitive skin, but some users report it still leaves their skin dry.

Dr. Bronner’s Pure Castile Soap – Dr. Bronner’s is a classic, especially among those who frequent Whole Foods. This is not just for hair and body; it has a purported 18 uses. You can also use it for laundry, dishes, and cleaning your floors. 

Dove 3-in-1 – Dove specifically markets this product to men as a combination shampoo, conditioner, and body wash.  

Shampoo And Soap Bars Provide A Better Combination Product

Another multi-use option is to skip the plastic bottle and use a soap and shampoo bar. This is a great option to reduce waste and shower space. These bars are also fantastic for traveling; there is no need to fill tiny bottles to carry on.

Shampoo and soap bars are now being made as a high-end, intentionally multi-use product. Do not expect this to be like using your dad’s soap. As with the liquid multi-use products, sometimes you do have to cater to the more challenging between your hair and face.

Daughter of the Land Hair and Body Shampoo – The manufacturer recommends that if you do use a conditioner with this bar, to use only half as much. The bar is made with goat milk and all organic and fair-trade ingredients.

Dr. Bronner’s Pure Castile Bar Soap – Dr. Bronner’s is by far the most affordable combination bar option. A single bar usually comes in around $4 and will last for a couple months for most people. As with the liquid form, use on face, hair, dishes, clothes, and the floor.

Christophe Robin Hydrating Shampoo Bar – Although this is named a shampoo bar, it is intended for hair and body use.

Shampoo 2-in-1 bars will generally create less lather than traditional liquid soaps. Most are formulated without the specific surfactants known to create the foam. Consequently, shampoo bars are often appreciated by people who want to reduce paraben and sulfate exposure.

Takeaways when substituting body wash for shampoo

In a pinch, do not hesitate to substitute body wash for shampoo. Ultimately, they are both formulated to be safe. Safe, however, is not the same as ideal use or desirable results. Regularly replacing shampoo with body wash is likely to create dry hair that lacks shine.

People with short hair may find this outcome palatable as each strand does not need to live a long life as with long hair. Similarly, people with short hair report the most satisfaction with 2-in-1 body wash and shampoo products.

Two-in-one shampoo and body bars tend to be more nourishing for longer hair. They also come in many variations to support different hair needs.
