Hypotrichosis simplex is a rare hereditary hair disorder which is manifested by either isolated scalp hair affection or involves or body hair. The condition usually starts in the first decade of life. Diagnosis and treatment of HHS is challenging and in the absence of genetic testing, diagnosis of HHS is established by exclusion. Short hair occurs with different etiological background; it can be due to shaft breakage, falling at certain length or true inability to grow normal healthy hair. Good examination of other ectodermal tissues is mandatory to exclude other syndromes e.g. ectodermal dysplasia. Other metabolic disorders may give the same picture of fine hair. Some acquired disorders should be ruled out e.g. loose anagen syndrome which differs in the easily pulled hairs as well as hair bulb abnormalities (3).
