* Kesh (Uncut Hair): One of the five articles of faith in Sikhism is Kesh, the practice of keeping hair uncut. This long hair requires more maintenance and cleaning to stay healthy and presentable.
* Dastar (Turban): Most Sikh men and some women cover their hair with a turban. While the turban helps protect the hair, it can also trap sweat and oils, leading to a need for more frequent washing.
* Hygiene: Regardless of religious reasons, many individuals, including Sikhs, prioritize personal hygiene. Living in varying climates and engaging in different activities can contribute to the need for more frequent hair washing.
