Question: 1 / 400

What ingredient in shampoos helps remove product buildup?

Oils

Surfactants

Surfactants are the key ingredient in shampoos that effectively remove product buildup. These compounds reduce the surface tension of water, allowing it to more easily penetrate and interacts with dirt, oil, and residues from hair products such as gels and sprays. When applied, surfactants bind to these impurities, making them easier to rinse away with water.

Using a shampoo with surfactants helps in cleaning the hair and scalp thoroughly, preventing the accumulation of residues that can weigh hair down or cause it to appear dull. This is essential for maintaining healthy hair and scalp, as product buildup can lead to various issues, such as itching or dandruff.
