Excessive elasticity in hair, often described as a “stretchy” quality, indicates compromised structural integrity of the hair fiber. This characteristic arises when the hair shaft is overly porous and unable to retain sufficient moisture. When stretched, instead of returning to its original form, the hair extends significantly and may even break. An example of this would be hair that snaps easily when gently pulled after washing.
Understanding the reasons behind this increased elasticity is crucial for maintaining hair health and preventing further damage. Identifying and addressing the underlying causes can lead to improved moisture retention, increased strength, and reduced breakage. Historically, various practices and treatments have been developed to combat this issue, often focusing on protein replenishment and moisture balance within the hair.
