How is uncombable hair syndrome diagnosed?

Diagnosis is suspected at clinical examination and confirmed via visualization of the hair shaft anomaly under a microscope. When the individual hair strands are viewed under a microscope, the hair is either triangular- or heart-shaped on cross-section and has a canal-like longitudinal groove along one or two faces.[1]  Confirmation is made when the characteristic appearance affects at least 50% of the scalp hair.
