Antibiotics help folliculitis decalvans: Results of a large study of 82 patients

By: Dr. Jeff Donovan

Folliculitis decalvans (FD) is a rare scarring hair loss condition that is challenging to treat.  In a new study, authors from Spain looked back at records of 82 patients in their practice with folliculitis decalvans.

The authors found that a family history was present in only three patients. Severe disease was seen in 17 patients (21%). Patients who had their disease onset before 25 years of age and who had pustules were found to have most severe disease. Oral antibiotics like the tetracyclinesclindamycin and rifampicin helped the vast majority of patients.



This is one of the largest studies to date of this disease. It is an important study which shows features that are likely to be associated with the most resistant disease  (such as young age and pustules). The study gives us confidence that antibiotics are indeed helpful in this condition.
