5. Loss of Elasticity:
Loss of elasticity means that hair fails to return to its original shape after being stretched. Healthy hair has good elasticity, allowing it to endure styling without damage. When hair is bleached, its elasticity can drop significantly, leading to dull and limp hair. The International Journal of Trichology highlights that restoring elasticity requires a combination of moisture and protein treatments.

Proper care and monitoring of these signs are essential in maintaining hair health after bleaching.
