What is a basic requirement for maintaining a healthy scalp?

Maintaining a healthy scalp is fundamentally rooted in cleanliness. A clean scalp helps prevent the buildup of dirt, sebum, and product residue, which can lead to various scalp issues such as irritation, dandruff, or an unhealthy environment for hair follicles. Regular cleansing helps to remove these unwanted elements, promoting a balanced scalp environment and ultimately supporting healthy hair growth.

While hydration is also important for scalp health, it primarily relates to the moisture content of the scalp rather than the basic maintenance aspect. Regular trimming is significant for hair health and removing split ends but does not directly influence the scalp's health. Effective styling products can enhance the appearance of hair, but they do not serve the core requirement of keeping the scalp in optimal condition. Cleanliness stands out as the essential practice for ensuring the scalp remains healthy and conducive to healthy hair growth.
