Steps

Method 1

Method 1 of 4:

All-Purpose Shampoo Bar for Normal Hair

1. 
   1
   Add your oils, butters, and beeswax to a large metal pot. Use a food scale to weigh 9 oz (255 g) of coconut oil, 9 oz (255 g) of olive oil, 6 oz (170g) of castor oil, 4 oz (114 g) of apricot kernel oil, 1 oz (28 g) of shea butter, 5 oz (140 g) of cocoa butter, and 1 oz (28 g) of bee wax. Add each ingredient to the pot as you go.
2. 
   2
   Melt your ingredients over medium-low heat, stirring frequently. Once everything has melted, remove the pot from the heat. Use a food thermometer to check the temperature. Let the mixture cool down to 100 °F (38 °C).
3. 
   3
   Combine the lye and water in a metal mixing bowl. Working outside or in a well-ventilated space (an open garage is perfect), use a food scale to weigh 13 oz (370 g) of water and 4.5 oz (128 g) of lye. Add the water to a metal mixing bowl, then, carefully add the lye and stir until the is lye fully dissolved. Use a food thermometer to check the temperature. Allow the mixture to cool down to 100 °F (38 °C).

   • Always wear goggles, gloves, and an N95 or cloth mask when working with lye. The fumes can cause burns or eye and lung irritation.
   • The mixture will get hot due to the chemical reaction between the water and lye. Be careful not to burn yourself.
4. 
   4
   Pour the lye water into the oil mixture and blend them together. Use a spoon or stick mixer to blend until the mixture reaches the consistency of pudding. Weigh 1 oz (28 g) of essential oil and add it to the shampoo mixture, blending thoroughly.

   • Make sure the oil mixture and lye water are both 100 °F (38 °C) before mixing them.
   • Be careful not to splash yourself with lye water.
   • Choose an essential oil with a scent you like. You can use any essential oil for normal hair, but avoid lemon and camphorous oils (like eucalyptus) since those can be damaging. Avoid adding extra olive or castor oil to this recipe.
5. 
   5
   Pour the shampoo mixture into molds and cover them with plastic wrap. Use either one large silicone soap mold, or a silicone mold that’s divided into smaller buckets (similar to an ice cube tray). After covering them with plastic wrap, let the molds sit in the mold for 24 hours.
6. 
   6
   Remove the shampoo bars from the molds. Then, place them on parchment paper and leave them in a cool, dry place. Allow your bars to cure for 4-6 weeks.

   • Curing allows your shampoo bars to fully harden. It also removes lye, which can irritate your skin. The longer cure your bars, the milder your shampoo will be.
   • Shampoo bars have a shelf life of 3-12 months. Keep them dry to help them last longer.
   • You can cut the bars into smaller sizes, if you like.

Lye-Free Shampoo Bar for Sensitive Scalps

1. 
   1
   Melt 1 lb (450 g) of goat’s milk soap base in a large metal pot. Use a food scale to weigh the soap base, then add the soap base to the pot and melt it slowly over low heat. Use a wooden or plastic spoon to stir the soap base as it melts. Once it’s fully melted, remove the melted soap base from the heat.

   • You don’t need to go outside or use a ventilated workspace since this recipe doesn’t contain lye.
2. 
   2
   Add shea butter, castor oil, and your essential oil of choice. Use a measuring spoon to measure 1 tsp (5 mL) shea butter and 2 tsp (10 mL) castor oil, then add them to the soap base. Then add 25 drops of any essential oil. Mix everything together.

   • Choose an essential oil with a scent you like. For sensitive scalps, you can use essential oils made cedarwood, chamomile, clary sage, or rosemary.

   Pour the shampoo mixture into a silicone soap mold. Use either a large silicone soap mold, or one that’s divided into smaller buckets (similar to an ice cube tray).
