Shampoo bars and Castile soap are similar, and in some cases they are identical. However, not all Castile soap is intended for use on your tresses and not all shampoo bars qualify as true Castile soap. For a better understanding of these sudsy wonders, look at how they’re made and the ways you can use them to freshen up your life.
Ingredients in Castile Soap
For a soap product to qualify as pure Castile soap, it must be made with 100 percent olive oil. The term "Castile soap" originated in the Castile region of Spain, where olives were abundant. In this area, soap was made with olive oil rather than the animal fats used in other areas. Occasionally, the term "Castile" is used to describe any soap made with a pure vegetable-based oil. When purchasing a product with the term "Castile" on it, check the ingredients to determine which type of soap it is.
Uses for Castile Soap
Castile soap can be used for different purposes. This versatile soap is gentle, especially when made with only olive oil. It can be used as a body wash, hand soap, dish soap and home cleanser. Any task you would perform with a soap product can be performed with Castile soap. Castile soap in all its forms is all natural, so it’s a mindful choice for those pursuing an eco-friendly lifestyle. Keep in mind, however, that a bar of Castile soap does not have antibacterial properties as strong as other cleansers.
Ingredients in Shampoo Bars
Shampoo bars are bars of soap made in the same way as any cold-process lye soap. Some form of oil or fat must be present to create the soap, and since the use of lard in soap is out of fashion today, typically a form of oil is used. If the oil used is olive oil, then the shampoo bar qualifies as pure Castile soap. Olive oil is a gentle ingredient for use on hair and can help to treat a dry, irritated scalp. However, other oils can be used as well. Jojoba oil has natural cleansing properties, while coconut oil provides a rich, foamy lather. Some companies describe natural soap bars made with these oils as Castile as well.
Uses for Shampoo Bars
Shampoo bars are specially designed to cleanse your hair. Rub the bar along your scalp or hair to transfer some of the soap to the hair. Then lather the soap up with your fingers and work it thoroughly throughout your hair. Rinse and repeat as desired. Because of the gentle properties of most shampoo bars, these cleaners can also be used on the face and body. This is a handy bonus for camper or hikers, but it is probably not a long-term solution for everyday use. Look for shampoo, body and face products that possess the best combination of ingredients for your skin’s needs.
