homemade castile soap shampoo

Castile soap is a natural, vegetable-oil-based soap that offers various uses. Organic castile soap provides much more benefits as it is made of 100%‌‌ organic ingredients free of harsh chemicals.

One of Castile soap’s many uses is as a replacement for chemical-filled shampoo. It is potent enough to cleanse the scalp of product build-up and excess sebum, yet gentle enough not to make the hair dry or stripped. Hence, castile soap is a great alternative to commercial shampoo. This article guides you through how to make a homemade shampoo with castile soap.

What to Prepare to Make a Homemade Shampoo With Castile Soap?

The items and ingredients users need to prepare to create a homemade shampoo with a castile soap are as follows:

  • A Shampoo Bottle: Users need to prepare a shampoo bottle or similar container that they can use to hold the homemade shampoo. The container or bottle should be able to hold around eight to sixteen ounces.
  • A Funnel: A funnel makes combining ingredients easier and less messy.
  • Castile Soap: Prepare around half a cup of either scented or unscented Castile soap, depending on the user’s preference. Nonetheless, they should note that organic soap The Blessed Soap can readily be used as a shampoo without adding other substances.
  • Chamomile or Peppermint Tea: Prepare half a cup of chamomile or peppermint tea that is brewed strong. Let it cool completely before use.
  • Essential Oil: Prepare around ten to fifteen drops of essential oil for hair (rose or lavender oil are great starters).

How to Make the Shampoo?

Below are the steps to make the shampoo recipe base. Users can use it as is or add or swap out some ingredients to their taste.

  • Step 1: Pour the tea into the container. Use a funnel to make the transferring easier
  • Step 2: Add the castile soap
  • Step 3: Take out the funnel and begin adding essential oils, drop by drop.
  • Step 4: Close the shampoo bottle and shake it well to combine all ingredients.

Since no preservatives or ingredients for stabilising the shampoo are used, users need to shake the shampoo bottle well each time before use. They should use the shampoo within one to two weeks for the best results.

Customising the Shampoo

Users can use various ingredient combinations to find the perfect one that suits their hair. Here are some ingredients that they can add to the shampoo base:

  • Peppermint Oil: Studies found that peppermint oil may help hair grow faster. Researchers from Korea reported that peppermint oil was more effective than minoxidil, the leading hair-loss prevention ingredient.
  • Lavender Oil: Lavender oil may promote hair growth, increase hair follicles and make hair thicker.
  • Honey: Adding a quarter cup of honey into the shampoo base recipe helps soothe and soften damaged hair.
  • Essential Oil for Dandruff: Some essential oils, such as peppermint, tea tree oil, thyme and bergamot, may help dandruff.
  • Aloe Vera: A quarter cup of pure aloe vera gel may help soothe the scalp and enhance the hair’s texture and shine. Aloe vera may also boost hair growth as it promotes cell growth and turnover.
  • Coconut Oil or Milk: Coconut milk is rich in vitamins and has moisturising and anti-inflammatory properties. Adding coconut oil to homemade shampoo can make the hair glossier and feel softer. However, adding coconut milk to the mix may shorten the shampoo’s lifespan.

Things to Watch Out for Before Using Castile Soap Shampoo

Before using castile soap as a shampoo, users need to note that castile soap can be potent and users should avoid using the soap directly onto hair or skin to prevent making their hair feel like straw. Be sure to dilute the castile soap first. The more soap they use, the stronger the solution will be. Using a small quantity of castile soap is generally enough.The Blessed Soap, however, can readily be used as shampoo without dilution


Making homemade shampoo using castile soap is quick and easy. Users can mix and match different ingredients to create the perfect shampoo for their hair. Still, the mixture can go bad pretty fast, so they should use it all up within one to two weeks.
