Solid shampoo has exactly the same function as the liquid version; it cleans the hair and the scalp and guarantees the same benefits: hydration, shine, softness, and other advantages. What changes is the environmental impact and the format; instead of being bottled, it comes in bar form or a dry disc.
As with traditional shampoo, there isn’t just one type of product for all hair: each texture deserves attention and special care. A solid shampoo is produced with a high concentration of active ingredients, which prolongs the use of each unit; on average it lasts 60 washes, equivalent to 2 bottles of liquid shampoo.
A simple task such as washing the hair represents a significant environmental impact that is in everyone’s hands, from water waste, energy consumption, and the discharge of chemical residues. However, there is a way to minimize the impact associated with washing: opt for solid shampoos, which are as effective as liquids.
Discover five advantages to switch from liquid shampoo to solid shampoo:
- Packaging with lower environmental impact
Typically, solid shampoos are sold in lighter and smaller packaging than those used for liquid shampoos, and therefore with a lower environmental impact.
- Lower water content in production
Generally solid shampoos have the same ingredients, but with a lower water content in their production. The production is relatively simple, with lower energy and time consumption.
- No preservatives
Few products contain preservatives in their composition, which reduces environmental impact and, in turn, also pollutes water less.
- Lower transportation impact
Because they are lighter and smaller than liquid shampoos, solid shampoos take up less space and allow a greater number of units to be transported, implying a lower impact.
- They last for more washes
Not always is the heavier solid shampoo the one that lasts longer; it depends on the formulation.
There are some recommendations to maximize the use of solid shampoo: before buying, take some time to read the label, avoid ingredients most harmful to the environment, and have the hair very wet before applying the shampoo, as this helps reduce the amount of product used.
At the end of using the solid shampoo you should always separate the empty cardboard packaging and place it in the blue recycling bin.
