What happens to hair that breaks easily or fails to return to its normal length?

1. It remains the same

2. It is over-conditioned

3. It has high elasticity

4. It has previous over-processing

The correct answer is: It has previous over-processing

Hair that breaks easily or fails to return to its normal length typically indicates that it has been previously over-processed. Over-processing occurs when hair undergoes excessive chemical treatments, such as coloring, perming, or relaxing, which can compromise its structural integrity. This damage affects the hair's ability to maintain elasticity and strength, resulting in breakage and an inability to regain its original length and texture. When hair is over-processed, the cuticle layer—the outer protective barrier—becomes weakened, making the hair more susceptible to damage from environmental factors and mechanical stress. This deterioration in the hair's condition can lead to split ends and overall hair fragility, which explains the observation that the hair does not return to its normal length after stretching or manipulation. In contrast, hair that remains unchanged or has high elasticity would show better resilience, while over-conditioning doesn't typically lead to breakage, but rather can make hair feel limp or heavy. Recognizing the signs of over-processing is crucial for effective hair care and treatment, highlighting the importance of balancing chemical treatments with proper conditioning and care.
