What can be a consequence of over-processing hair during perming?

When hair is over-processed during perming, it can lead to damage that makes the hair brittle and prone to breakage. This occurs because the chemicals used in the perming process can disrupt the hair's natural structure, weakening its integrity. The excessive chemical exposure leads to changes in the hair’s internal bonds, which can strip moisture and essential nutrients, ultimately causing the cuticle to become rough and the hair shaft itself to lose strength.

A common consequence of over-processing is the loss of elasticity, meaning the hair cannot withstand normal styling or environmental stressors without breaking. In contrast, while some may think over-processing could enhance shine or improve color uptake, the reality is that the damaged hair often becomes dull and lifeless instead. Additionally, over-processing can cause curls to become overly tight or frizzy, but the primary danger remains the increased brittleness and risk of breakage. Thus, understanding the balance of chemical application is crucial for maintaining healthy hair during perming.
