What happens to hair with normal elasticity when stretched?

  1. It breaks

  2. It turns dull

  3. It shrinks

  4. It returns to original length

The correct answer is: It returns to original length

Hair with normal elasticity has the ability to stretch and then return to its original length. This characteristic is crucial for maintaining the overall health and appearance of the hair. When hair is subjected to stretching due to styling or environmental factors, it should be able to extend without breaking or becoming damaged, provided it possesses normal elasticity. In conditions where hair exhibits good elasticity, it can endure tension and pressure, such as when styling with heat or during manipulation. This ability to return to its original form after being stretched helps prevent breakage and maintains the integrity of the hair shaft. Understanding this aspect of hair elasticity is essential for barbers and stylists, as they can select appropriate techniques and products to improve or maintain hair health. Additionally, recognizing poor elasticity could indicate underlying damage that may require treatment or specific care.
