Scalp health and the consequences of infrequent hair washing

Infrequent hair washing can lead to the accumulation of sebum, dead skin cells, sweat, and hair product residues on the scalp. While the frequency of washing depends on individual factors such as hair type, age, activity levels, and scalp oil production, delaying washing for too long can cause visible issues.

Sebum is a natural oil produced by glands to protect the skin and prevent hair from drying out. However, when not washed away, it mixes with other substances to create buildup. This can result in hair appearing oily, greasy, or flat, particularly in individuals with fine hair.
