What does hair elasticity refer to?

Hair elasticity refers to the stretchability and strength of the hair. This characteristic indicates how well hair can stretch and return to its original shape without breaking. Hair that has high elasticity can endure styling practices such as curling or straightening without sustaining damage, while hair with low elasticity may break or frizz more easily under similar conditions.

This aspect of hair health is crucial for maintaining its integrity, especially when undergoing chemical treatments or heat styling. When evaluating the condition of hair, professionals often test elasticity to determine the appropriate products and care methods to use, ensuring the hair remains healthy and resilient. Understanding elasticity helps cosmetologists provide tailored care, which contributes to the overall performance and appearance of hair.
