title: Loose Anagen Syndrome: A Retrospective Chart Review of 37 Cases.
abstract: OBJECTIVE
  Loose anagen syndrome (LAS) is a disorder of abnormal anchorage of the hair to the scalp. Its symptoms include an inability to grow hair long and hair that is easily pulled out.
  
  
  METHODS
  We conducted a retrospective chart review of patients with LAS over the last 10 years at the Children's Hospital of Philadelphia and found 37 cases.
  
  
  RESULTS
  LAS was more common in females and was found in all hair colors and skin types.
  
  
  CONCLUSIONS
  Diagnosis of LAS should be made based on history, microscopic findings, and hair bulb and shaft features.
