Loose Anagen Syndrome: A Retrospective Chart Review of 37 Cases.

ABSTRACT

BACKGROUND/OBJECTIVES: 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. CONCLUSION: Diagnosis of LAS should be made based on history, microscopic findings, and hair bulb and shaft features.
