Which of the following is a common result of inadequate hydration of the hair?

1. Enhanced shine

2. Increased elasticity

3. Split ends and breakage

4. Improved color retention

The correct answer is: Split ends and breakage

Inadequate hydration of the hair often leads to split ends and breakage. When hair is not properly hydrated, it becomes dry and brittle, which makes it more susceptible to damage. Healthy hair retains moisture and has a certain level of elasticity, allowing it to bend without breaking. However, when hydration levels drop, the structural integrity of the hair fibers weakens, resulting in fraying, splitting at the ends, and an overall increased likelihood of breakage. In contrast, enhanced shine comes from properly hydrated and well-maintained hair, as moisture helps to smooth the cuticle, reflecting light better. Similarly, increased elasticity is a characteristic of hair that is well-hydrated, allowing for flexibility without damage. Improved color retention is also linked to healthy, hydrated hair, as moisture helps to maintain the integrity of color molecules within the hair strands. Therefore, lack of hydration clearly relates to the deterioration of hair condition, manifesting predominantly as split ends and breakage.
