Personal Uses for Castile Soap

1. Face Wash: Add 2 or 3 drops to wet hands, and wash face as normal.

3. Shampoo: Put half a tablespoon in your hand and work into damp hair. Follow up with a conditioner to detangle. One Facebook fan said she always uses the peppermint scent for this as it helps invigorate the scalp.

4. Bath Soak: Use approximately 2 tablespoons of castile soap in an average tub and add a few drops of essential oil if desired.

10. Aftershave: Add 1 or 2 drops in a spray bottle with 4.2 ounces of distilled water. Peppermint, eucalyptus and tea tree work well. For sensitive skin, use the Baby Mild version.

DIY Dr. Bronner's Recipes:

Before we dive into the DIY recipes, keep in mind that castile soap must be used correctly, so avoid mixing it with vinegar or other acids like lemon because the acidity would cancel out the castile soap, which is the base.5

1 Coconut Shampoo

Combine all ingredients in a shampoo bottle or jar and shake well to mix. You can keep it in the shower for up to one month. Shake before each use.

2 DIY Kitchen Wipes

Cut the old t-shirt into rag-size cloths. Mix water, soap and essential oil into the jar. Place rags into the jar and close the lid. Soak the rags by turning the jar upside down a few times with the lid on. After, wash the cloths and return them to the jar for multiple uses.

3 Moisturizing Hand Soap

Pour castile soap and coconut oil into bottle. Add essential oils. Fill the rest of the way with water, leaving room for the foaming pump. Screw on the pump top and swirl the container a few times.
