I tested an easy recipe, made from a soap base and not from caustic soda, a saponification agent (yes, that’s a word) which is difficult to find and which requires several precautions when handling it.

Indeed, there is a chemical reaction that occurs when mixing caustic soda and this can cause serious burns! So let’s take a little shortcut, okay?

There are different soap bases you can buy, but I like the glycerin base, usually made from coconut oil (also called lauric acid in the ingredients) and goat milk.

This is what I recommend you use: these two ingredients are very nourishing for the hair!

  • The soap base is mostly sold in a 2-pound (900 g) package.
  • Here we are going to use about 1/4 of the package or if you have a scale, simply weigh the soap!

DIY Shampoo Bar Ingredients Needed

The recipe is really simple: Melt the ingredients, mix, and pour into a mold. Literally, anyone can do it!

Here are the properties of the ingredients:

  • Coconut oil: protects the tips, anti-dandruff, softens the hair
  • Goat milk: a good source of minerals like potassium and phosphorus, which the hair needs. It also has calcium.
  • Castor oil: It helps thicken hair and stimulate its growth  (can also use olive oil or argan oil)
  • Shea butter: acts as a conditioner, hydrates hair, and treats an irritated scalp
  • Vitamin E oil: helps to maintain a healthy scalp and makes the hair shine

For essential oils, I used a mixture of ylang-ylang, sweet orange, bergamot patchouli, and some incense.

The DIY Shampoo Bar Recipe

This makes about 3 bars, depending on the size of the mold used.


– About 250 grams of glycerin soap base

– 4 tablespoons of shea butter

– 2 tablespoons of castor oil

– 2 tablespoons of vitamin E oil

– A few drops of soap coloring (optional)

– 30 to 40 drops of essential oils of your choice

It is also necessary to have a soap mold, usually plastic or silicone, but you can be creative and do it for example in a large ice cube mold.

Note: The mold should not be too rigid or otherwise it will be very difficult, if not impossible, to unmold.

And this recipe can have several variations, just use a different essential oil (s) each time you make it.

DIY shampoo bar recipe


  1. Unmold the glycerin soap from its original packaging and cut it into small cubes (it should normally be pre-portioned for this to be easier). Weigh it if possible.
  2. Pour the soap cubes into a large microwave-safe measuring cup.
  3. Add the castor oil and shea butter.
  4. Heat in the microwave at 30-second intervals, mixing well each time. The power of the microwaves varies, but it should take 1 minute and a half to 2 minutes before everything is melted and homogeneous.
  5. Add the vitamin E oil, the dye if you use it, and the essential oils.
  6. Pour into the cavities of the soap mold and do not handle until everything is really set (which can take from 30 minutes to 2 hours, depending on the size of the mold).
  7. Unmold and use!

Tips to Make Your DIY Shampoo Bar Last Longer

Like commercial bars, this soap will tend to melt quickly in the shower.

This is because it is not triple-milled, or “refined three times”, a longer and more complex process that allows bar soap to last longer.

To overcome this, keep it in a closed case or simply outside the shower.

3 Best Selling Homemade Shampoo Bars


Does this famous shampoo bar recipe work well? Yes, it works well. Just a little setback, it doesn’t foam as well as the factory processed ones.

This is because the store-bought shampoo bars, which we adore, contain sulfates (that is the little “grated” pieces we see through the bars). This agent foams perfectly, but it is also controversial and several experts recommend not using it.

Why? Because sulfates work so well for cleaning hair that they can completely remove the protective natural oils and have an irritant effect. So maybe it is bad for good? It’s up to you to decide.
