Solid Shampoos: Why They Are the Best Choice for Your Hair
Solid shampoos have moved beyond a niche alternative to become the preferred option for those seeking healthier, more sustainable, and economical hair care. At Prana Market, we have selected solid shampoos with clean and certified formulations, two of which achieve the highest INCI Beauty score: 20/20.
In this article, we explain the advantages of this format, what the INCI Beauty score means, and compare the three solid shampoos available in our store side-by-side.
Advantages of solid shampoos
- More concentrated and cleaner formulas. Without water in the composition, there is less need for preservatives and more room for ingredients that truly care for your hair.
- Zero plastic. A single bar replaces, on average, two to three bottles of conventional liquid shampoo, drastically reducing waste.
- More cost-effective. They last much longer than they appear: since they are concentrated, each wash uses a minimal amount of product.
- Ideal for travel. They are not liquid, do not spill, and pass through hand luggage control without problems.
- Respect for the scalp. Our solid shampoos use plant-derived surfactants and a balanced pH, cleaning without harshness or dryness.
What the INCI Beauty score is and why it matters
INCI Beauty is an independent platform that analyzes the ingredient list (the "INCI") of each cosmetic and assigns a score from 0 to 20, based on the safety and profile of each component. The higher the score, the cleaner and safer the formula.
A score of 20/20 means an irreproachable composition: no controversial ingredients, no endocrine disruptors, no substances suspected of being carcinogenic or accumulative. It is the maximum guarantee that what you apply to your hair, and what comes into contact with your scalp and body, has been formulated with your health in mind.
At Prana Market, we prioritize precisely this type of formula: Clean Beauty, free from harsh sulfates, silicones, parabens, and synthetic fragrances.
