The Complete Guide to Natural Solid Shampoo: Everything You Need to Know
Jul 16, 2026
Natural solid shampoo is no longer a niche alternative: it has become a fundamental choice for those who want beautiful, healthy hair, a simpler routine, and a reduced environmental impact. At Maison Jearom, we have made this format our specialty — with an ultra-high concentration of natural active ingredients, a Grasse fragrance, and a unique refillable case.
This guide answers all your questions: what is a natural solid shampoo, how to choose it, how to use it, and which products match your hair profile.
What is a natural solid shampoo?
A natural solid shampoo is a compact bar-shaped hair cleanser, formulated primarily from naturally derived ingredients. Unlike traditional liquid shampoos, it contains no (or very little) water: the formula is therefore more concentrated in active ingredients.
At Maison Jearom, our solid shampoos contain 95% naturally derived ingredients, with a concentration of active ingredients up to 4 times higher than a traditional liquid shampoo. The result: less product per wash, more effectiveness, and a reduced ecological footprint.
Why switch to solid shampoo?
- Concentrated effectiveness: each wash delivers an optimal dose of nourishing and cleansing active ingredients.
- Zero waste: no plastic bottle to throw away, especially with our refillable case system.
- Easy travel: compact format, accepted in the cabin, no risk of leaks.
- Gentle formulas: sulfate-free, respectful of the scalp and the environment.

Natural solid shampoo: frequently asked questions
Does a solid shampoo clean as well as a liquid one?
Yes, and even better, provided it is well formulated. Our natural solid shampoos contain gentle, plant-derived cleansing agents that effectively remove impurities without irritating the scalp.
How long does a bar last?
Approximately 2 to 3 months for daily use, equivalent to 2 bottles of 250 ml liquid shampoo.
Can it be used on color-treated hair?
Absolutely. Our gentle formulas are compatible with vegetable or chemical dyes. Our Radiance Revealer range is even dedicated to color preservation. For a complete routine, consult our natural color-treated hair routine guide.
