Liquid shampoo
Among the liquid shampoos, Lidl’s Cien Day by Day Fruit/Vitamin Shampoo Power & Volume Normal Hair took first place. The shampoo can convince in all categories and is free of critical fragrances. It gives the hair volume in the practical test, makes it supple and easy to grip and gives it shine. In addition, the hair can then be easily combed. The only points of criticism: the laboratory finds polyquaternium in the Lidl shampoo, a substance that is poorly biodegradable. According to the manufacturer, there are also three preservatives in the shampoo: Sodium Benzoate, Potassium Sorbate and Formic Acid. According to the manufacturer, however, the recipe has since been changed. In the rating, the shampoo scored “good” overall (grade 1.9). The test winner costs around 1 euro in the store. at Amazon is the Lidl shampoo also available, but currently sold out.
Solid shampoo
When it comes to solid shampoos, the Alverde solid shampoo with a tangerine-basil scent for normal hair from dm takes first place. When it comes to care properties, it’s not quite as good as the best liquid shampoo. The hair cannot be optimally detangled after washing and the shampoo favors individual “flying” hairs. The hair is still supple and shiny. In addition, the natural cosmetic product scores “very well” in terms of packaging. And the solid shampoo is free of preservatives and those that are poorly biodegradable. Overall, the dm shampoo cuts off “good” (grade 2.1). The 60 gram piece costs in the shop around 4 euros.
hair soap
Among the hair soaps, the Finigrana rosemary hair soap wins. These are also certified natural cosmetics that are free from preservatives and harmful substances. Although the hair is easy to comb after washing and there is little flyaway hair, it is less convincing in the other sub-categories of care properties. In terms of ease of detangling, suppleness, grip/gloss and volume, the hair soap only scores “satisfactory”. Dosing the right amount is also a bit more complicated with Finigrana hair soap than with the other two winners. Overall, the best hair soap in the test still gets the rating “good” (grade 2.4). You get the Finigrana rosemary hair soap from about 6 euros (to Idealo).
