Which type of shampoo contains no detergents or solvents?

Herbal or organic shampoos are formulated without synthetic detergents or solvents, focusing instead on natural ingredients derived from plants and botanicals. These shampoos utilize herbs, essential oils, and natural extracts, which serve to cleanse the hair and scalp without the harsh chemicals typically found in traditional shampoos. This makes them especially suitable for individuals seeking gentle cleansing options that minimize irritation and preserve the natural oils of the hair and scalp.

In contrast, medicated shampoos often contain specific active ingredients designed to treat scalp conditions, which may include synthetic compounds or medicinal agents. Mild shampoos, while gentler than standard commercial options, may still contain some form of mild detergent to aid in cleansing. Protein shampoos are designed to strengthen hair and typically include protein or amino acid components, but they can also have various cleansing agents and may not be free of all synthetic ingredients.
