Make your own Castile soap-based shampoo and conditioning hair rinse

DIY Shampoo from Liquid Castile Soap

- 1/8 tsp Olive or Almond oil (optional, for dry hair)
Tip: The essential oils we recommend are peppermint, lavender, rosemary, and orange or a blend of them.
How to make
- Combine all ingredients in an old shampoo bottle or jar of some kind (pump soap dispensers work well for this).

- Before each use make sure to shake the bottle well.
- Can be stored and used for up to one week.
Castile Soap
Traditionally the term Castile, in regard to soap, referred to a hard white soap made from olive oil. It was named for the Castile region of Spain where they made soap only using olive oil. In recent times this term has become more loosely defined as a pure vegetable-based soap (void of any animal products). A pure olive oil soap makes a moisturising soap, but it doesn’t lather well, so many soap makers find that using a blend of different oils allows them to customize the properties of the soap better. Most Castile soap today is actually a blend of olive oil, coconut oil, castor oil, or any other commonly used vegetable oil. Castile soap can be made as either hard bar soap or liquid soap.

Conditioning Hair Rinse
Ingredients
- 10ml Apple Cider Vinegar
- 240ml Water or cooled brewed Green tea
- 3 drops Essential oil (optional) such as lavender
How to make
- Combine ingredients in a clean re-purposed squirt bottle (an old shampoo bottle for example).
- Double up on ingredients until you fill your bottle.
- Shake the bottle well before use.
- Apply the conditioner to the scalp (being careful not to get into the eyes), and gently massage into the hair and scalp for a minute or two and rinse. After drying your hair will not smell like vinegar.
This conditioner is the best option for use after a homemade shampoo or a shampoo bar. Whether you are making a Castile soap-based shampoo or a baking soda-based shampoo, the vinegar rinse will smooth the hair and eliminate the greasy, sticky feeling. If you use green tea it may help to stimulate the scalp and improve hair health.
Apple Cider Vinegar Benefits
Apple cider vinegar is packed with nutrients that are great for building luscious locks, including B vitamins, vitamin C, and potassium. Because it is slightly acidic, it also serves to restore the natural pH of the acid mantle. Exposure to this acidity hardens the outer layer of the hair and flattens the cuticle, resulting in hair that shines, “slides” easily, and is less prone to tangling or snagging.
