Easy Homemade Shampoo Ingredients

• 1/4 cup grated soap (castile soap is a common choice)
• 1/4 cup hot water
• 1/2 tsp olive oil
• 2 tablespoons glycerine
• ~5 drops essential oil (optional, for fragrance or therapeutic properties)

Let's Make Shampoo!

1. Dissolve the soap in the hot water.
2. Stir in the olive oil. You can substitute another vegetable oil if you like, but olive oil is generally accepted as healthy for skin and hair.
3. Add the glycerine and any essential oils you might want. Typical essential oils would include lavender, peppermint, or citrus.

You can use this shampoo as-is or as a base for specialized recipes for oily hair, dry hair, dandruff, etc.

Shampoo Ingredients

• 2 lb 10 oz olive oil
• 1 lb 7 oz of solid-type vegetable shortening
• 1 lb coconut oil
• 10-1/4 oz lye (sodium hydroxide)
• 2 pints water
• 1-1/2 oz glycerine (glycerol)
• 1/2 oz alcohol (I'd use vodka or other food-quality ethanol and call it close enough. Do not use methanol.)
• 1-1/2 oz castor oil
• essential oils (optional), such as peppermint, rosemary, lavender, for fragrance and therapeutic properties

Let's Make Shampoo!

1. In a large pan, mix together the olive oil, shortening, and coconut oil.
2. In a well-ventilated area, preferably wearing gloves and eye protection in case of accidents, mix the lye and water. Use a glass or enameled container. This is an exothermic reaction, so heat will be produced.
3. Warm the oils to 95°F-98°F and allow the lye solution to cool to the same temperature. One of the easiest ways to accomplish this is to set both containers into a large sink or pan full of water that is at the correct temperature.
4. When both mixtures are at the proper temperature, stir the lye solution into the oils. The mixture will turn opaque and may darken.
5. When the mixture has a creamy texture, stir in the glycerine, alcohol, castor oil, and any fragrance oils or colorants.
6. You have a couple of options here. You can pour the shampoo into soap molds and allow it to harden. To use this shampoo, either lather it with your hands and work it into your hair or else shave flakes into hot water to liquefy it.
7. The other option is to make liquid shampoo, which involves adding more water to your shampoo mixture and bottling it.

You may have noticed that many shampoos are pearlescent. You can make your homemade shampoo glittery by adding glycol distearate, which is a natural wax derived from stearic acid. The tiny wax particles reflect light, causing the effect.
