For dry scalp and hair, which types of scalp preparations should be avoided?

Strong soaps and greasy preparations should be avoided for dry scalp and hair because they can strip the scalp of its natural oils or create an overly greasy environment. A dry scalp lacks sufficient moisture, and using harsh cleansing agents can exacerbate dryness and irritation.

Additionally, greasy preparations can lead to an imbalance in the scalp's moisture levels, causing further discomfort and possibly leading to other issues like dandruff or product buildup. This approach is more detrimental than beneficial, especially for those seeking to hydrate and nourish dry hair and scalp.

In contrast, moisturizing agents, hair serums, and leave-in conditioners are designed to provide hydration and nourishment, making them more suitable options for individuals dealing with dryness.
