Questions asked by users might not always be phrased in the clearest way.
Shampoos with high foam typically contain surfactants, which are molecules with both a hydrophilic (water-loving) head and a hydrophobic (water-hating) tail. These surfactants lower the surface tension of water, allowing for the formation of bubbles. Anionic surfactants, such as sodium lauryl sulfate (SLS) and ammonium lauryl sulfate (ALS), are commonly used in shampoos due to their strong foaming properties.
