"Dry hair" typically indicates a lack of moisture and possible damage because healthy hair should retain an adequate level of moisture, which gives it elasticity and shine. When hair is dry, it often feels brittle, rough, and can be prone to breakage. Often, dryness can be due to various factors such as environmental influences, excessive use of heat styling tools, chemical treatments, or inadequate hair care. Recognizing dry hair as a sign of potential damage underscores the importance of proper hydration and appropriate hair care treatments to restore moisture and overall health.

In contrast, high oil content suggests an excessively oily scalp or hair, which has a different set of care requirements. Healthy and strong hair typically has a good balance of moisture and oils, while recently washed hair may appear less oily but does not necessarily mean it will be dry; it generally should be in a better condition if washed correctly.
