What effect can excessive shampooing have on the scalp?

Excessive shampooing can strip the natural oils from the scalp. The scalp produces sebum, which is a natural oil that helps to protect and moisturize both the scalp and hair. When shampoo is used too frequently, especially if it's a strong or clarifying formula, it can remove these essential oils. This can lead to dryness, irritation, and flakiness on the scalp, which may cause discomfort and potentially worsen scalp conditions. Maintaining the balance of natural oils is crucial for a healthy scalp environment, which supports not only scalp health but also hair health overall.
