Loose anagen hair syndrome in a child

Abstract

Loose anagen hair syndrome (LAHS) is due to a defective anchorage of the hair shaft to the follicle, resulting in retarded hair growth and diffuse or patchy alopecia. LAHS usually presents as diffuse alopecia in blonde girls, occurring as isolated cases but rarely in association with hereditary or developmental disorders. We report this case because of the unique presentation of LAHS in a dark-skinned male toddler as patchy alopecia in association with developmental delay.
