Loose anagen hair syndrome is characterized by thin and sparse hairs that can be easily extracted upon mild traction. The disorder affects predominantly children. Trichogram shows at least 70% of loose anagen hairs devoid of inner and outer hair sheaths, presenting a ruffled cuticle at the proximal portion. Although benign and self-limited, the disorder frequently concerns parents and should be further differentiated from telogen effluvium and trichotillomania.
