Sustainable living with SOLIDU

It's Thyme

No water.

No plastic.

Only concentrated goodness.


SOLIDU is an environmentally conscious, innovative cosmetics brand from Lithuania. Plastic pollution is one of the biggest threats facing humanity, and plastic waste, such as cosmetic product bottles, takes around 500 years to biodegrade.

At SOLIDU we create low-waste solid products packaged in backyard compostable boxes. While your everyday haircare products contain around 80% water, these bars are made only from the necessary elements: skin-loving active ingredients, botanical oils, extracts, and natural essential oils. Being small and compact, they not only do not contain any plastic but also reduce emissions of transportation.

SOLIDU packaging is plastic-free as well as paper-free, completely natural, and can be backyard composted in 45 days.
