Shampoo Hair Soap Types

Solid Shampoo

Solid shampoos are the eco-friendly version of conventional liquid shampoos. Their composition is similar to that of their liquid counterparts, with the distinct difference that the water component has been removed.

These shampoos consist of various surfactants, oils, perfumes, and colorants which work well to form a lather similar to that of liquid shampoos.

One bar of solid shampoo is the equivalent of two liquid shampoos. The pH value of solid shampoos is generally equal to that of the skin.

Hair Soap Bars

Hair soaps are what the name suggests: soaps that cleanse the hair. Saponifying oils and fats manufacture them with lye.

These products have an alkaline pH value; therefore, it is advised to follow up with a so-called acid rinse after shampooing. An acidic rinse entails using a water-vinegar or water-lemon juice solution to rinse the hair.

The acidic rinse has several benefits: it seals the hair follicle, encourages shine, and prevents limescale buildup.

How To Choose The Perfect Shampoo Hair Soap For You

When choosing the perfect shampoo hair soap for you, there are important considerations to keep in min.
While hair soaps have more simple formulations, solid shampoos have the advantage of not requiring an acidic rinse after use. As a result, you need to consider your hair type.

  • Low porosity hair: It definitely benefits from washing with hair soap bars. This hair type has a very closed creatine cuticle. Therefore it is difficult for care products to penetrate the hair. Instead, they layer as a build-up on the hair and weigh it down.
  • Medium-porosity hair: It definitely benefits from hair soap bars with the right ingredients. Medium porosity hair has slightly opened creatine scales, leaving the hair not completely protected from moisture loss and external environmental influences.
  • Highly porous hair: Has wide-open creatine cuticles, absorbs water and care easily, but they can’t store it. It is, therefore, often rough, dry, and brittle.
  • Dyed hair: It is less damaging to the hair if the hair is permanently dyed darker than bleaching. Her dark color pigments are brought into the hair fibers. If you have colored, highly porous hair, your hair could benefit from hair soap bars containing creatine.
  • Bleached hair: Nowadays, hair is bleached with many trendy colors. This damages creatine fiber in the hair. The more shades of color the hair is lightened, the more it is damaged. In this case, you should wash your hair with shampoo bars to avoid yellowing and discoloration.
