There are many simple homemade shampoos you can create without having to use castile soap. Castile soap is traditionally made from olive oil, but can be derived from any vegetable oil. The natural soap may be the most popular choice for homemade shampoos, but there are still other ingredient options available. Most castile-free homemade shampoos can be categorised as dry, glycerine or oil-based.
Homemade Dry Shampoo
Castile-free, dry, homemade shampoos are liquid-free cleansers that attract dirt and oil. When the dry shampoo is brushed out of your hair, some of the dirt and oil is brushed away as well. Dry shampoos are handy for camping trips and other situations with limited room or restricted water. However, they only partially clean your hair and eventually a liquid shampoo will need to be used for a deep cleansing.
Some baking soda, cornstarch or cornmeal is all you need to create a simple dry, homemade shampoo. Just sprinkle a little into your hair, brush it out and your done. Never use dry shampoo on wet hair or you'll end up with a sticky mess. Store the shampoo in a water-tight container, such as a sealable plastic bag, to prevent the powder from absorbing moisture and becoming useless.
Homemade Glycerin Shampoo
Castile-free, homemade, glycerine shampoos are almost as popular as castile soap shampoos. Glycerine is a natural byproduct of the soap-making process. It's a deep moisturiser that can be derived from animal or plant oils. Most glycerine soaps for homemade shampoo come in bar form and must be melted into the shampoo recipe to work. It melts at only 71.1 degrees C, so always use low heat to slowly turn the bar into liquid.
Glycerine shampoos tend to be on the watery side, but they're just as powerful as any thick and bubbly shampoo. The most popular glycerine shampoo recipes are nothing more than glycerine melted into herb-infused water. The exact herbs may change, according to your hair colour and type, but the basic process remains the same. Regardless of which recipe you choose, always shake glycerine shampoos well before each use.
Homemade Oil-Based Shampoo
Castile-free, homemade, oil-based shampoos are basically just conditioners that help carry away dirt as they moisturise. Any homemade conditioner recipe can double as an oil-based shampoo. The method works best for people with very dry hair who need an extra boost of moisture. Using an oil-based shampoo is as simple as conditioning your hair. Just get your hair wet, add the conditioner, work it through your hair and rinse it out.
