Azelaic acid

Has anyone heard about a study done in France involving the use of zinc, vitamen B6, and azelaic acid to treat hairloss? I have heard that the combination lowered DHT levels 90% in the scalp. If anyone else knows anything about this study(or any other documenting azelaic acid’s effectiveness against alopecia) please let me know. Also, does anyone know how long it takes for propecia to start working? I started taking it 3 months ago and(maybe its just my imagination) the line is still creeping back.
