What potential issue could occur from excessive heat during hair processing?

Excessive heat during hair processing can lead to heat damage, which often manifests as breakage. When hair is exposed to high temperatures for extended periods, the proteins within the hair structure can become compromised. This results in the cuticle layer lifting, making the hair more porous and susceptible to damage. Over time, this can lead to dryness, brittleness, and ultimately, breakage of the hair strands.

While other aspects such as hair elasticity may be initially affected by heat treatments, excessive heat ultimately harms the overall integrity of the hair. Enhanced color absorption and quick drying may seem like immediate benefits of heat; however, they do not come without risks. Prolonged exposure to high temperatures increases the likelihood of damaging the hair rather than providing a safe and effective treatment. It's essential to use heat carefully and understand its potential consequences to maintain hair health.
