How is uncombable hair syndrome diagnosed?

A diagnosis of uncombable hair syndrome (UHS) is made by observing the characteristic symptoms of the condition, as well observing the hair shaft under a special microscope.[1] When the individual hair strands are viewed under a microscope, the hair is either triangular or kidney-shaped on cross section, and has a canal-like longitudinal groove along one or two faces.[2][3] People with concerns about symptoms of UHS are encouraged to speak with their dermatologist about being evaluated for this condition.
