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.
