In Japan, where liquid shampoo is the norm, "shampoo bars (solid shampoos)" are still not very well known.
However, in Europe and America, they are already sold alongside liquid shampoos in drugstores, and have become a part of daily life as "environmentally friendly and easy-to-use hair care products."
Many people who actually try them feel that they "lather well," "leave hair moisturized and manageable," and are "surprisingly easy to use," and are now starting to attract attention in Japan for their functionality and convenience.
In this article, we will cover the basics of shampoo bars, their spread in Europe and America, the benefits of using them in Japan, and the "shampoo bar for Japanese people" that we propose.
What are solid shampoo bars?
What is a shampoo bar?
A shampoo bar is a solid shampoo made by solidifying the ingredients of liquid shampoo without water.
It is used by lathering directly on the hands or hair, or by rubbing it on a net.
Although it looks like soap,
it is truly a shampoo specifically for "hair and scalp."
Since it doesn't use water, it's compact and light, and some products can last 2-3 months per bar.
It's great for daily use, as well as for travel and the gym.

Differences from soap
While they may look similar,
shampoo bars and soap are completely different.
| Comparison Item | Shampoo Bar | Soap |
| Main Use | Hair/Scalp, some can wash the whole body | Body |
| Cleansing Ingredients | Amino acid-based, Cocoyl Isethionate, etc. | Fatty acids + caustic soda (soap) |
| pH | Mildly acidic to neutral, similar to hair and skin | Alkaline |
| Effect on hair | Smooth, some do not require conditioner | Can be squeaky and dry |
In other words, a shampoo bar is not "washing with soap,"
but rather "a solid with the function of shampoo."
