What is the primary purpose of a scalp astringent lotion?

The primary purpose of a scalp astringent lotion is to remove excess oil from the scalp. Astringents function by tightening the skin and reducing the production of sebum, which is the natural oil produced by the skin. In the context of hair care, this can help alleviate issues like oily scalp conditions, allowing for a cleaner scalp and healthier hair growth.

Using a scalp astringent is particularly beneficial for individuals who tend to have oily scalps, as it can contribute to a fresher, more balanced environment for the hair follicles. This approach can also enhance the effectiveness of other products used afterward by ensuring that the scalp is free from excess oil, which may impede the absorption of treatments or styling products.

While some might confuse astringent properties with moisture addition or exfoliation, those functions are typically addressed by other products specifically designed for hydration or physical or chemical exfoliation of the scalp.
