If you've been making your own cold process soap and using it in your shower, how about using your soap as a shampoo?

Many people use their cold process soap as a shampoo bar as well. But hair is different than skin, so you need to do a few things differently in order to have the best results. Most soap makers recommend:

1. Formulating your recipe differently—both in terms of the oils chosen, but in the additives and superfat percentage
2. Using a vinegar or citric acid rinse
3. Knowing that some people's hair just doesn't work well with real soap—and being okay with going back to a standard surfactant-based shampoo. There are so many variants, like the hardness of the water where you live and your particular hair type, that they just don't work for everyone.

Homemade Shampoo Recipes

First, for the best results on your hair, there are a few changes you can make to your regular soap recipe that will help your soap work better on hair. Castor oilmakes great shampoo, as do the softer oils like avocado, canola, and almond.

Here are three recipes to get you started. Feel free to customize them or use similar oils that you may have on hand. (For example, you can easily substitute palm kernel for the coconut, or rice bran for the olive, or lard for the palm.)

Included are the percentages of each ingredient to make a 2 lb. batch of soap. They can be scaled up or down according to your needs.

Note: The superfat/lye discount is calculated at 6 percent for these recipes. Some people prefer a low (3 percent or so) superfat in their shampoo bars, others prefer a high (10 to 15 percent) superfat in their recipes. Give 6 percent a try and then adjust up or down depending on your preference. Be sure to always run your recipe through a lye calculator! These recipes will still all probably take at least 48 hours to harden in your soap mold.

Basic, Mild Shampoo Recipe

1. 25 percent coconut oil
2. 25 percent olive oil
3. 20 percent castor oil
4. 15 percent canola oil
5. 15 percent palm oil

Light Cleansing Recipe

1. 30 percent coconut oil
2. 25 percent olive oil
3. 25 percent castor oil
4. 10 percent canola oil
5. 10 percent palm oil

Luxury Shampoo Recipe

1. 25 percent coconut oil
2. 20 percent olive oil
3. 20 percent castor oil
4. 10 percent canola oil
5. 10 percent palm oil
6. 10 percent avocado oil
7. 5 percent jojoba oil

To make these soaps, follow basic soap making instructions. The amount of water in these recipes are low so that they will harden quicker in the molds. The high percentage of soft oils in the recipes can make them take a while to harden in the mold.

You'll want to make sure to add the salt and the sugar to the lye water. The salt helps the soap to get harder quicker and the sugar helps boost the lathering ability of the soap.

Rinse

Because of the high pH of cold process soap, most people use a slightly acidic rinse on their hair after using a shampoo bar. The high pH raises the cuticle of the hair follicle, making it more prone to damage. The rinse helps lay it back down.

You can make the rinse out of either:

1. 1 cup vinegar (apple cider or white) to 2 cups water or
2. 1 tbsp. citric acid powder to 3 cups water

Give shampoo bars a try. Some people rave about them; some people like them, but prefer a traditional shampoo.
