How To Make Shampoo Bars? Sharing my Secret Recipes

by Shopify API on Jul 06, 2024


Are you looking for a shampoo alternative that is earth-friendly and economical? If so, you may want to try making shampoo bars.

They are easy to make, and they last a long time. They make an excellent alternative to commercially prepared shampoos.

They can be made with most organic oils and herbal extracts. In this tutorial, Restorbio will show you how to make shampoo bars using natural ingredients.

The Basic Anatomy Of A Shampoo Bar

While shampoo bars are often made using a complicated chemical process called saponification (the same cold process soap), they can be made with everyday ingredients and simple kitchen tools. Shampoo bars are generally caused by mixing fats (e.g., oils from plants, lard from animals) and lye (also known as sodium hydroxide).

The concoction is then left to cure for approximately a month. Making bars with lye requires heat for saponification. However, the heat happens naturally, so cooking is unnecessary.

What is Saponification?

Saponification refers to the chemical reaction where fat or oil is mixed with lye. This results in soap making.

As shampoo bar making involves many steps, it is best to measure your ingredients ahead of time and keep them on hand. Cover surfaces with newspaper before you start a shampoo bar recipe. Make sure to protect your skin with goggles and gloves. Saponification can cause intense fumes that can burn skin.

Are Shampoo Bars Safe for Hair?

Friese believes that DIY shampoo bars are a viable alternative to liquid shampoos if they contain beneficial ingredients. DIY bars are suitable for people with allergies and those concerned about the elements of their hair care product.

The creator is in complete control of the components. Bars are better suited for short hair because it is easier to clean the scalp with a bar than with long hair.

Choosing Oils for hair

You can add softness and luster to your hair with some oils. These oils can be used on all hair types, even colored hair.

  • Sweet Almond Oil
  • Avocado Oil
  • Macadamia Nut Oil
  • Castor oil
  • Palm Oil
  • Wheat Germ Oil
  • Grapeseed Oil
  • Rice Bran Oil

You can use many oils to make your homemade shampoo bar. However, you will want to keep the SAP value the same as the coconut and olive oils. To ensure that the oil you choose is within the same range, consult an SAP chart.

*Castor oil is excellent for hair, but it is not very high on the scale. You will need to reduce the amount of lye by approximately one teaspoon if you decide to use it. This will make the mixture more even. Otherwise, you'd end up with a crumbly bar because of too much lye.

This homemade shampoo bar is my go-to for conditioning. I use a 1:13 mixture of apple cider vinegar and water. To soften and shine your hair, apply it right after you get out of the shower. The vinegar scent dissipates quickly.

How to Use DIY Shampoo Bars

Friese explained the art of using shampoo over traditional liquid shampoos. Wet your hair, making sure it is damp. Otherwise, it will be hard to create a lather.

To create suds, you will need to wet the bar using a little water. Massage the shampoo bar onto your hair, distributing it evenly. Finally, use your fingertips to scrub your scalp gently.
