Which is a common sign of over-processed hair?

A common sign of over-processed hair is excessive breakage or split ends. Over-processing often occurs due to the frequent application of chemical treatments, such as coloring, perming, or relaxing, which can cause the hair's structure to weaken. This weakening leads to brittleness, resulting in hair that breaks easily or develops split ends.

In healthy hair, the cuticle is intact and smooth, allowing the hair to maintain its strength and elasticity. However, when hair is over-processed, this structure is compromised, making it more susceptible to damage. As a result, individuals might notice significant hair breakage and an increased number of split ends, indicating that the hair cannot withstand regular styling or environmental factors. This is a critical observation for cosmetologists when assessing hair health, as it requires specific care and restorative treatments to improve the condition of the hair.
