Make your own natural and luxurious goat milk shampoo bars with this simple, easy-to-follow recipe from herbalist Jan Berry’s new book.
These goat milk shampoo bars have a generous helping of castor oil to promote a great lathering experience, along with a full amount of goat’s milk for an added creamy and luxurious feel. Shea (or mango) butter helps to slightly harden the finished bars while providing moisturizing properties for the scalp and hair. Commercial shampoos pale in comparison to natural shampoos like this one.
This natural shampoo bar recipe is from Jan Berry’s new book, Simple Natural Soapmaking.
Before making these shampoo bars, you’ll need to freeze the milk. To do so, weigh out the amount of milk you need for the recipe directly into ice cube trays. Freeze until solid, and store the cubes in freezer bags until you are ready to make the soap.
Making the Best Shampoo Bar Ever
Yield: 7 to 8 bars of soap (2.5 lbs/1.13 kg)
8.5 oz (241 g) frozen goat’s milk
0.5 oz (14 g) distilled water
3.9 oz (111 g) sodium hydroxide (lye)
7.5 oz (213 g) coconut oil
3 oz (85 g) shea or mango butter
10.5 oz (298 g) olive oil
3 oz (85 g) sweet almond or sunflower oil
4 oz (113 g) castor oil
1.23 oz (35 g) of lavender essential oil, optional
Substitutions and Tips
So that you are aware, you must weigh all ingredients. You’ll need an accurate scale to make soap.
To replace the shea or mango butter, use lard or tallow instead. The lye amount will stay within an acceptable range for either change and will not need to be adjusted. If you are allergic to coconut oil, try using an equal amount of babassu oil in its place. The lye amount should be slightly reduced to 3.85 ounces (109 g) for this replacement.
Directions for Making Goat Milk Shampoo Bars
Place the frozen goat’s milk and water in a heavy-duty plastic or stainless steel bowl. Wearing protective gloves and eyewear, carefully sprinkle a small amount of lye at a time over the frozen milk, stirring well after each addition. The entire process will take several minutes, but working slowly ensures that the milk doesn’t scorch and that the lye completely dissolves. The lye solution does not need to cool further before being added to the oils.
Melt the coconut oil and shea butter, then add them to the other oils. Add the lye/milk solution to the oils. Using a combination of hand stirring and an immersion blender (stick blender), stir the soap until it reaches a very light trace. Trace is when the soap has thickened enough that when you drizzle a small amount of the batter across the surface, it will leave a fleeting but visible imprint or “trace,” before sinking back in. At trace, stir in essential oil, if using, then pour into a prepared mold.
Jan Berry recommends the Crafter’s Choice Silicone Soap Mold.
Let the soap stay in the mold for 24 hours. The next day, you’re ready to unmold and slice into bars. It is safe to use your soap after a few days, but I recommend putting the soap somewhere cool, dry, and with good airflow for four to six weeks. The extra water will evaporate, making the bars harder, so they last longer in the shower.
Benefits of Goat Milk for Hair
The proteins and fatty acids in goat milk shampoo bars nourish hair and make it naturally shiny. If you have curls, goat’s milk shampoo will help control frizz and make your curls sculpted. Also, because it’s gentle and it helps to moisturize the skin, you may find dandruff relief after using goat milk shampoo bars. You may also see some boosted hair growth.

Benefits of Goat Milk for the Body
Goat milk soap offers the same benefits for the body as it does for the hair. Commercial soaps contain surfactants that strip your skin of its natural moisture and oils, leaving it feeling dry and tight. Packed with skin-loving fatty acids, like caprylic acid, goat milk soap cleans without stripping your skin of its natural oils, leading to dry skin.
Goat milk’s lactic acid content helps to gently remove the top layer of dead skin cells, allowing for natural exfoliation. Unlike other alpha-hydroxy acids, lactic acid is known as one of the gentlest AHAs, making it an ideal choice for those with sensitive skin.
