If store-bought shampoo isn’t doing it for you anymore, we’ve got you! 

Making your own shampoo bar is the perfect way to control which ingredients you’re introducing to your hair. 

It’s going to take some time to heal your scalp from all of those added chemicals but, once you do, you’ll notice a big difference in hair quality and texture. 

Without further ado, let’s make some shampoo bars! 

What You’ll Need

-16 oz Melt and Pour Goat Milk Soap Base Block

-2 tsp of Castor Oil

-1 tsp of Shea Butter

-Essential Oils of choice (we used Orange Sweet and Ylang Ylang) or Fragrance Oil 


Using a soap cutter or sharp knife, cut the block of soap base into small, cubed chunks. 

Place these chunks in a glass measuring cup. Either double boil or microwave the soap until it becomes a smooth liquid. 

Add castor oil and shea butter and again mix until smooth and evenly combined. 

Drop between 25-35 drops of your essential/fragrance oil into the mixture and stir. We added 20 drops of Orange Sweet and 10 drops of Ylang Ylang essential oils based on scent. 

Pour mixture into soap mold of choice. We used a silicone soap loaf mold but you could use any of our soap molds. Get creative or keep it simple; it’s up to you! 

Leave overnight to harden in the mold/s. 

Then, remove from the mold and cut, if necessary, into bars from the long soap loaf. 

You should be able to get about 4 bars or soaps out of this recipe. 

We got six because we cut them into pretty small bars to show the width and depth. 

Consider measuring with a ruler before cutting to make sure that they’re even if they’re to sell! 

It smells amazing and looks great! But you can always add pigment powder or a soap color block for a little bit of spice. 

Recommended Scents

Oatmeal, Milk, and Honey with oatmeal added in for a natural scalp exfoliant. 

Coconut Milk and Lavender for a natural, calming scent. 

Lavender and Rose Essential Oils for a naturally flowery scent. 

Our Herbal Essences type scent to make it smell like an actual, store-bought shampoo. 


If you want to get a good lather to spread the soap in your hair better, rub the bar in your hands first and then spread the soap in your hair. 

For a beautiful soap top, wait for the soap top to get slightly more solid and then use a spatula to make designs on the top or add dried botanicals for a unique look. 

To help it last even longer, leave it on a soap lift or soap saver in the shower. This allows excess water to drain and prevents excessive breakage while you use it!
