Stiftung Warentest: This was the leader in the hair test
In the test of Stiftung Warentest all liquid shampoos were rated well with an overall score. However, some of the liquid hair care products also contain substances that are not necessarily recommended. Preservatives were only found in the liquid products. Even substances that are difficult to biodegrade could only be found in the liquid shampoos.
The top seller among liquid products comes from the discounter Lidl. The vitamin shampoo for normal hair achieved a rating of 1.9. It is the only product in the test that managed to get a 1 before the comma in the overall rating.

Another outlier in the test by Stiftung Warentest is the hair soap "Natur All Hair Types" from Savion . In the declaration and advertising statements category, the product, which costs just 15 cents per hair wash, only managed a poor rating of 5.0. The provider advertised, among other things, that his product was fragrance-free, but the experts at Stiftung Warentest were able to prove several in exactly this product.
In addition, the rating of the soap is pulled down due to the lack of a reference to the use of acidic rinse. When using hair soap, the use of such a rinse is specifically recommended. This rinse of water and vinegar helps against the so-called "lime soap", which is created due to the lime content in the water.
Stiftung Warentest: In the test, all soaps in the packaging category were top
In the category of packaging in were able to test by Stiftung Warentest all soaps for the hair are determined to achieve a very good rating. In contrast, the experts at Stiftung Warentest noticed that a firm shampoo from Foamie had been used as a mock pack.
This earned the product "Foamie - Solid Shampoo Normal Hair" a grade 5 in the packaging category. The packaging of the soap feigned more content than was actually contained.
Stiftung Warentest: The eco balance in the test was clearly a better one for soaps
When testing the eco-balance, Stiftung Warentest compared, among other things, the environmental impact of washing hair with liquid and solid shampoo or soap. During the test, they came to the conclusion that both are equally harmful here.
However, the environmental impact of the liquid shampoo in terms of manufacture and transport is many times higher than that of the solid alternative.
