What is the name of the condition where hair ends become dried out and damaged due to overexposure to heat or chemicals?

Trichoptilosis is the term used to describe a condition where the ends of the hair become dry and damaged, often as a result of overexposure to heat or chemicals. This condition manifests as split ends, where the hair fibers fray and separate, leading to a rough texture and a lack of smoothness in the hair.

The damage often comes from harsh hair treatments, such as excessive styling with hot tools, frequent coloring, or chemical processing. Trichoptilosis signifies that the hair has endured stress that disrupts its natural moisture balance, causing the cuticle to wear away and the underlying structure to be exposed. Regular trims and the use of conditioning treatments can help to manage and mitigate this condition, but understanding its causes is crucial for preventing further damage and maintaining healthy hair.
