To the Editor: We describe two patients with epidermolysis bullosa simplex, Dowling-Meara type (EBS-DM), who also have loose anagen hair syndrome (LAHS). EBS-DM is a severe form of EBS marked by widespread herpetiform blistering, worse during infancy.1 LAHS is diagnosed by the ability to painlessly extract anagen hairs from the scalp that lack an external root sheath and demonstrate cuticle ruffling distal to a misshapen bulb.2 The hair is typically sparse and seldom requires cutting.2 An association between these entities has not previously been reported, to our knowledge.
