What’s the difference between Hand Soap, Shampoo Bar and Shampoo

Something might happen if you have used soap to cleanse up your scalp and hair.

1. Residue on hair:

soap scum……This is a chemical reaction. Couldn't get rinsed off with water.

2. inflammatory skin disease:

Seborrheic dermatitis is an inflammatory skin disease that can affect people infrequently. If you have ​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​eczema or seborrheic dermatitis, avoid using soap to clean your hair.

3. Dry and brittle hair:

Soaps can leave your hair dry, frizzy, and brittle as it rips off the natural oil and keratin of the hair.

Why would that happen? You may have heard that Soaps aren’t formulated for hair and are unable to clean your hair gently.

soap is a mixture of sodium salts of different fatty acids. It is produced by a process called saponification or hydrolysis of fat or oil. Soap is an alkaline product with a pH between 9-10. It is excellent in removing the dirt and bacteria from the skin. This is because the skin has an acid mantle that keeps away bacteria from entering the skin. Once the skin is cleared with soap, the acidic mantle of the skin can return to its normal pH level easily.

Soaps Vs Shampoos

Soaps are solid at room temperature; hence there is not much scope to add any additional ingredients while making them. On the other hand, shampoos are liquid that gives the cosmetic chemists flexibility to add more ingredients while formulating them. For example, they can infuse conditioning agents that can leave the hair feeling soft and healthy.

Shampoos are cleansing agents that leave no residues. Also, soaps are usually not formulated for hair specifically. So while you can use soap to wash your hair occasionally, making this a regular habit can damage your hair.


The hair, on the other hand, has a pH level between 4.5-5.5. The acid environment of the scalp and hair prevents any bacterial or fungal growth. However, if you wash your hair with soap, the soap's alkalinity will destroy the natural keratin of the hair. As a result, your hair will become dry and brittle.

That's why… Most of the hairdresser would tell you that Shampoo is better than soap.

Shampoo Bar

Shampoo Bar is a solid shampoo. Specify formulated for hair use.

You find it in a compact format, very similar to a hand soap bar and for this reason in English it is also called shampoo bar. But, to all intents, it is a shampoo!

However, no shampoo bar is perfect

At this point you may be wondering: so is a solid shampoo better than the liquid one? There's no firm answer to this question, because no shampoo is perfect for all uses and under all sustainability profiles.

The solid shampoo does not need to replace the liquid one, since they can compliment each other! Exactly in the same way that it happens due to the biodiversity in nature, if we want to obtain products that are always more and more effective and sustainable, we need to diversify our approach.
