Best For You, Your Hair & The Planet; Liquid vs Solid Shampoo

3 min read

Girl with great hair

In the USA over 550 million empty shampoo bottles are discarded every year with the average American going through 11 bottles of shampoo a year!

While this statistic specifically refers to liquid shampoo bottles, it highlights the significant environmental impact of traditional packaging.

Solid shampoo bars, on the other hand, offer a more sustainable alternative, , though they still need to be pH balanced. This means avoiding the many 'alkaline' shampoo bars on the market, such as soap-based bars or those with high pH primary surfactants.

Although precise usage numbers for solid shampoo bars are not readily available, their popularity has been steadily increasing due to environmental awareness and conscious consumer choices.

To put it in perspective, if even a fraction of the USA population switched to using solid shampoo bars, it could significantly reduce plastic waste.

Solid bars are more concentrated than liquid shampoo, which means less packaging and more efficient transportation.

While we don’t have an exact count of how many solid shampoo bars are used annually, the growing interest in eco-friendly alternatives suggests that their adoption is on the rise.

So, if you’re considering making the switch, you’re contributing to a positive change for the environment! 

Solid shampoo and liquid shampoo comparison 

In the USA, approximately 307.84 million Americans used shampoo in 2020. 

While this statistic specifically refers primarily to liquid shampoo usage, it provides insight into hair care habits.

The global shampoo bar market has been on an upward trajectory, driven by several factors. Let’s delve into the details:

Market Size and Growth:

In 2021, the global shampoo bar market was valued at USD 9.98 million. By 2022, it had already grown to USD 10.8 million. The market is projected to continue its expansion, reaching USD 19.41 million by the year 20301.

Drivers of Growth:

Health and Hygiene Awareness: Increasing awareness about health, hygiene, and the adverse effects of long-term use of chemical cosmetics and personal care products has fuelled demand for shampoo bars. 

Plastic Waste Concerns: Consumers are gravitating towards packaging-free personal care products to reduce plastic waste. Shampoo bars, with zero plastic packaging, align with this trend. 

Natural Ingredients: Growing awareness of harmful chemicals in traditional products has led consumers to seek natural alternatives. Shampoo bars made from organic, herbal, and natural ingredients are gaining popularity. 

HairLoss Concerns: Approximately 80 million Americans suffer from hair loss, prompting interest in all-natural and organic hair care products, including shampoo bars. 

Environmental Impact: Plastic waste poses a significant environmental challenge. Manufacturers are increasingly avoiding plastic packaging, especially in cosmetics. 

Government Policies: 

Stringent regulations support the use of organic and natural cosmetics. For instance, the European Commission has prohibited certain parabens in cosmetic products. These policies are expected to further boost the adoption of shampoo bars in the foreseeable future. 

In summary, the shampoo bar market is riding the wave of eco-consciousness, health awareness, and demand for sustainable alternatives.

As consumers seek effective yet environmentally friendly options, shampoo bars are carving out a niche in the personal care industry.

Clearly, the growing interest in eco-friendly alternatives more than suggests that their adoption is on the rise.
