research Mosaic Hair Regrowth Pattern of Ophiasis and Androgenic Alopecia in a Patient With Alopecia Areata Totalis May 2004 The patient with total hair loss did not regrow hair despite treatment, indicating a poor outlook for this type of hair loss.
research Adrenal 21-hydroxylase gene mutations in Slovenian hyperandrogenic women: evaluation of corticotrophin stimulation and HLA polymorphisms in screening for carrier status 19 citations , August 1999 in “European journal of endocrinology” The study concluded that testing hormone levels after stimulation is not reliable for identifying carriers of 21-hydroxylase deficiency; genetic testing is necessary.
