Not washing your hair for a week can keep the natural oils called sebum in your hair and scalp which results in shiner, healthier hair and a less dry scalp.
The natural oils like sebum help to maintain your hair's moisture content and prevent dryness and enhances shine.
And natural oils can also help you with your hair texture and manageability and potentially reduce your need for hair styling products.
Over washing of your hair can also trigger your scalp to produce more of the sebum and natural oils and skipping of washing your hair for a week can help re-regulate the natural oil production.
Ideally you should wash your hair at least once a week unless your hair gets more dirty more often although some people are okay with going a week without washing their hair, especially if there hair does not get really dirty.
