Solid Shampoo Bars Kit

Make your own solid shampoo bars

Create your own solid shampoo bars at home with this easy-to-use DIY kit. Solid shampoo bars are a great way to reduce plastic waste in the shower, and when cared for properly, they last a surprisingly long time.

The bars in this kit are vegan and cruelty free, and the formula has been designed to produce a gentle, creamy lather while leaving hair feeling clean and conditioned.

Important Note on Cocoa Butter

Due to a current global cocoa butter shortage, this kit temporarily includes natural (non-deodorised) cocoa butter rather than deodorised cocoa butter.

While used at a relatively low percentage, the natural cocoa aroma may subtly influence or compete with added essential oils or fragrance oils. Many customers enjoy the soft chocolate note, but it’s worth considering when choosing your scent.

About the Ingredients

Some of these ingredients may be unfamiliar, so here is a quick overview of what they do in the formula.

Sodium Cocoyl Isethionate (SCI)
A coconut oil–derived surfactant that is exceptionally mild on skin, hair and eyes. SCI produces a creamy, luxurious lather and is widely used in solid shampoo bars and gentle cleansers.

Conditioner pellets (BTMS-25)
A conditioning emulsifier that provides excellent slip, detangling and softness. Commonly used in both leave-on and rinse-off hair products.

Cetearyl alcohol
A fatty alcohol used as a thickener and structure builder in hair and skincare formulations. It contributes to bar hardness and a smooth texture. Made from sustainably sourced RSPO mass balance certified palm oil.

Decyl glucoside
A mild, plant-derived surfactant from the alkyl polyglucoside (APG) family. Known for its gentle cleansing properties and strong environmental profile, it pairs well with SCI to balance cleansing and foam.

Lactic acid
Produced from fermented corn. In this formula, lactic acid helps improve bar hardness and longevity and supports overall product performance.

Hydrolysed quinoa
A plant-based protein rich in amino acids. It helps support hair strength, softness and shine and is commonly used in conditioning and protective hair formulations.

Coco caprylate
A natural emollient derived from coconut oil that provides slip, spreadability and a lightweight conditioning feel, helping the bars glide smoothly through the hair.

Microcare DB
An Ecocert-approved broad-spectrum preservative suitable for water-containing products.
