Add to wish list

A stylish addition to the plastic free bathroom, this solid shampoo bar is highly concentrated; containing just natural goodness without any water to dilute it. This formulation enables the bar to be very compact, and although small, lasts as long, or even longer than a conventional bottle of shampoo that when empty, takes around 500 years to biodegrade.

This 'Grandma Said' solid shampoo bar for fine hair is so called because Grandma said to rinse your hair with the water from boiled stinging nettles to keep it healthy! In Lithuania and nearby regions, they have long used nettle infusions to stimulate hair growth, increase shine and improve the structure of the hair.

Powdered organic nettle leaves and tamanu oil are the two main magical ingredients in this bar, added to intensely moisturise and condition, leaving weak or damaged hair with more volume. Tamanu oil is a great source of hair nutrients, used to regenerate and restore hair and scalp to its healthy state. Cold-pressed and unrefined, it has a very thick consistency and is full of natural aroma, like freshly cut grass and raw nuts. The brownish-green oil is pressed from the tamanu nut and is rich in nutrients such as linoleic, oleic, palmitic and stearic acids. Tamanu oil is often used on broken, chemically treated and weak hair.

Cedarwood, rosemary, and juniper essential oils are added to stimulate the scalp and give the shampoo its resinous, woody scent.

The bar has a modern faceted shape for ease of application. Simply lather the bar in your hands, glide it evenly over wet hair and massage in. Rinse well to eliminate any residue and stand the bar somewhere dry to air. A natural loofah slice makes a fantastic compostable shampoo rest, and is available to purchase separately.

Hand crafted by a small team in Lithuania from natural and organic ingredients. Produced in small batches to ensure maximum freshness and packaged in a black, plastic-free compostable box made from starch, bamboo and charcoal, without any synthetic dyes added.

Free from micro plastics and silicones.

Vegan friendly.

Box measures approximately 8cm x 7.5cm x 4cm high.

Presented in plastic-free packaging produced from starch, bamboo, and charcoal. Bamboo is one of the most sustainable materials on earth, growing up to a metre per day. To make this box, bamboo is processed together with natural starch. The material is dyed with charcoal without using synthetic dyes.  

Once the product is used up, tear off the paper labels and put them into the paper recycle bin. They are completely plastic-free, however, the compostable box will biodegrade faster without the paper labels. Put the packaging in the compost bin or in the soil where it will break down in around 45 days, becoming a nutrient for the soil.

The idea for SOLIDU started when Founder Vaiva decided to get rid of all of her belongings to travel the world with only a backpack. Knowing she would be pressed for space, she discovered solid cosmetic products and marked the birth of SOLIDU as we know it!

Today, SOLIDU Cosmetics is an environmentally conscious, women-owned innovative cosmetics brand from Lithuania, creating low-waste solid body and hair care products packaged in environmentally friendly compostable boxes. The brand continuously aims to empower ambitious Lithuanian women to join a meaningful mission, with the team being around 90% female.

Most everyday haircare products contain around 80% water. SOLIDU bars are made only from the necessary elements: skin-loving active ingredients, botanical oils, extracts, and natural essential oils. The lack of water allows them to create a small and compact product, which is not only is plastic-free, it also reduces transport emissions.

Plastic pollution is one of the major threats currently facing humanity. The cosmetics industry is a huge contributor to this plastic waste and Solidu decided from the onset that they wanted to be different.

SOLIDU is changing the way the world looks at cosmetics and, in turn, is creating a better life for future generations.
