The kit offers a price saving compared to purchasing products separately and ensures that complementary products are already paired, with no risk of incompatibility.

Yes, the application 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: run the solid under running water or rub it 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 well-ventilated area or in an open R5 solid soap 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, well-ventilated place. Never leave it submerged in water, even partially, as this accelerates its consumption and can promote moisture buildup

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, and it is the international standard for verifying that a cosmetic does not cause skin irritation. Our protocol involves: 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 Cosmetic Regulation and the Declaration of Helsinki The test demonstrates that, under the indicated experimental conditions, the product does not cause skin irritation reactions in the tested population. For our solids, the result was IIM = 0 (Mean Irritation Index equal to zero), a “non-irritating” classification according to the modified Draize scale. This is not a specific test for atopic skin (atopic subjects are excluded from the study). It is not an allergy test. It does not replace a personal patch test in cases of reactive skin or known allergies The “dermatologically tested” claim applies to all R5 solid products, each of which has undergone its own dedicated patch test. Each product has its own report, available for technical consultation upon request

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