260931

Round, square, rectangular, shampoos become solid and come in convenient, compact and fragrant formats. Meeting the favor of the public, who crowned them this season’s sales princes. A passing fashion or a discovery with more concrete and future-oriented perspectives? The shampoo-bar it is not just a matter of captivating shape or generic green attitude, it is rather a step, actually pleasant, towards a more sustainable lifestyle.

«It is in fact an invention developed to save water, space and plastic: a stick of solid shampoo is equivalent on average to two bottles of classic shampoo and allows considerable savings also in terms of consumption to produce, transport and distribute it. Since it does not contain water, it reduces its use by up to 90%, but above all it avoids waste ”, he explains Umberto Borellinicosmetologist and lecturer at various universities.

The “naked” product also does almost completely without packaging, which it is recyclable and zero impact. It is no coincidence that the first solid shampoos were proposed years ago by independent brands committed to the ecological front.

Today they have also spread among the major brands because never as now the attention is focused on the health of the planet as a necessary premise for individual well-being, with the corollary of green proposals also in terms of beauty. A discourse that appeals to those who are most attentive to ecology, but which is also conquering those who, pragmatically, are looking for an immediate advantage in terms of time and quality for themselves.

The new shampoo bars, in fact, are easy to carry: in the gym and pool bag they take up minimal space and weigh only a few grams. A plus that you can also take advantage of when you travel: on the plane they go in hand luggage without problems, and in general weight and mini dimensions leave more space in the suitcase. An expanding universe that offers new products every month.

But which are the best? We have examined 14, preferring 4. Find out by what criteria we have chosen them.

The formula

“Solid shampoos look like soaps, but they aren’t: they are a compound of solid surfactants and nourishing plant-derived oils or butters. They have one highly effective detergent and produce foambut the presence of fats compensates for the potential aggressiveness with emollient qualities and leaves no residue once rinsed », says cosmetologist Umberto Borellini.

These “soaps not soaps” for hair then have the advantage of requiring less water to rinse because the formulas are highly biodegradable. In addition, they help to condition the lengths, making it easier to comb thanks to the vegetable component.

“The best ones in fact have a high percentage of natural lipids such as wheat germ, coconut, olive oil or mango butter (you can find them on the label with the Latin name such as triticum vulgare, cocos nucifera, olea aeuropaea etc ). Some also contain ingredients, natural or synthetic, to increase the cosmetic result of softness of the hair, such as honey or waxes ».

It goes without saying that they are not meant to cleanse the whole body, unless otherwise specified on the package, and shared use should be avoided for hygiene reasons.

Proof

We washed our hair every two days with solid shampoos without applying rinse-off conditioner but only in leave-on form on dry hair, in order to evaluate the result of the shampoo.

We considered the type of packaging, the balance of the foam, the pleasantness of the scent and its persistence, the ease of use of the block in the shower and the result on the hair after drying. We also evaluated the value for money and preferred the products that, with the same performance and satisfaction of the formula, were cheaper or easier to find.

Advice

Like all new products, solid shampoo must be learned to dose according to your needs. Obviously, short hair is easier to manage but this type of cleanser also washes long hair well, without exceeding the doses: just wipe the wet stick on the wet head, especially on the areas that tend to get dirty more, and massage. Thick hair, after washing, still requires a rinse-off conditioner and the usual post-cleansing care.

«A special attention, then, must be dedicated to the conservation of the shampoo-bar, which it should not be left on the poolside or in a wet soap dish. The stagnation of water, in fact, not only causes it to dissolve, but also allows bacteria to proliferate. The ad hoc boxes in metal or cork. For those who use it in the shower, at home or in the gym, the cotton bags with drawstring closure are also practical to hang it and avoid water stagnation, but then it is always better to keep the product tightly closed away from dust and humidity », Concludes the cosmetologist Umberto Borellini.
