THE LOOSE anagen hair syndrome (LAS) is a sporadic or familial hair disorder that primarily affects children but may occasionally be seen in adults.1-8 The condition is due to a defective anchorage of the hair shaft to the follicle, resulting in easily and painlessly pluckable hair. Patients with LAS complain of slow-growing hair and diffuse or patchy alopecia. The clinical manifestations of the disorder are in most cases mild, and it is likely that only a small proportion of children with the condition seek dermatological advice.
