Trichoptilosis

Trichoptilosis (from the Greek τριχο- tricho- "hair" and the New Latin ptilosis "arrangement of feathers in definite areas" from the Greek πτίλον "feather"), schizotrichia, and informally split ends, is the splitting or fraying of the hair-shaft due to excessive heat and mechanical stress. This condition occurs when the outer layer of the hair is damaged and the hair fibre divide into two or more strands.

==Types of split ends== === Double split === The most common type of split ends, where the single hair forks into two. === Feather split === In this type of split ends, the hair appears feathered at the end, with multiple splits splaying out. === Tree split === In this type, the ends branch out multiple times, resembling branches of a tree. === Knot split === The hair has a bulb at the end, becoming thicker at the tip.
