Yes, the method is slightly different, but it only takes 2–3 uses to get used to it. A solid cosmetic is a concentrated formula without water (or with a minimal amount). The water that normally makes up 60–80% of a traditional liquid shampoo or shower gel is replaced by the shower water: wet the product, create a lather, apply, and rinse as you would with a traditional cosmetic. The 3 steps: Activate: rub the solid under running water or between wet hands until a creamy lather forms Apply: distribute over wet hair and/or body and massage gently Rinse and store: rinse thoroughly, then leave the solid to dry in a ventilated area or in an open R5 solid cosmetic holder with drainage Why "solid" does not mean "less effective": the same concentration of active ingredients you would find in a 250/300 ml bottle is concentrated in a 70 g solid. An R5 solid cosmetic averages about 60 uses; its lifespan depends on the frequency of use, hair length, and storage method. Practical tip: after showering, leave the solid in a dry, ventilated place. Never leave it immersed in water, even partially, as this accelerates its consumption and can promote moisture buildup

There are three main reasons, with an honest look at the compromises. 1. Plastic reduction A 70 g R5 solid averages about 60 uses and replaces a traditional 250–300 ml bottle. On an annual basis of regular use, for every solid product purchased, at least one plastic bottle is avoided. If you multiply this by all shower cosmetics (shampoo, conditioner, shower gel, face products), the overall impact becomes significant over time. 2. Less water transported Liquid cosmetics contain an average of 60–80% water, an ingredient that has an energy and environmental cost during transport. A solid weighs less and takes up less volume 3. More concentrated ingredients Without the "diluting" water, every gram of solid is richer in functional ingredients (oils, butters, surfactants, extracts). The result is a more concentrated product per unit of weight. The compromises to be aware of: A different usage habit: it requires activation with water and dry storage between uses An initial adjustment: if you are used to traditional cosmetics with silicones, the first 2–3 washes may feel different to the touch: this is normal, it is the hair "resetting" without the silicone coating A seemingly higher price per unit: however, based on the 60 actual uses, the cost per single wash is competitive with premium bottled cosmetics

It means that every R5 solid product has undergone a clinical test on human volunteers in an accredited laboratory, under the supervision of a dermatologist, before reaching you. How it works: The test is called an epicutaneous patch test, it is the international standard to verify that a cosmetic does not cause skin irritation. Our protocol includes: 25 healthy volunteers testing the product on their own skin Application for 48 consecutive hours Evaluation by a dermatologist at three different times after removal (15 min, 1h, 24h) Accredia accredited laboratory: Complife Italia (one of the most authoritative in Italy) Ethical compliance with the European Cosmetics Regulation and the Declaration of Helsinki The test demonstrates that, under the indicated experimental conditions, the product does not produce skin irritation reactions in the tested population. For our solids, the result was IIM = 0 (Mean Irritation Index equal to zero) the "non-irritating" classification according to the modified Draize scale. It is not a specific test for atopic skin (atopic subjects were excluded from the study). It is not an allergy test. It does not replace a personal patch test in case of reactive skin or known allergies The claim "dermatologically tested" applies to all R5 solids in the range individually subjected to a dedicated patch test. Each product has its own report, available for technical consultation upon request

Store it in a solid cosmetic holder that allows water to drain. Solids last longer if they are allowed to dry well between uses.
