What is jesser hair?

As an AI language model, I do not have access to a specific person named "Jesser Hair". However, if you are referring to the general topic of hair, it is a protein filament that grows from follicles found in the skin. Hair serves several purposes such as protection, heat regulation, and sensory input. Hair comes in different types and textures ranging from straight to curly, and can also be dyed or styled. Proper hair care involves washing and conditioning regularly, protecting it from heat damage, and getting regular trims to prevent split ends.
