A recent scientific research paper was published about the possible link of Acitretin and hair loss. This is drug typically used against psoriasis (when taken orally). One possible side effect of using this drug is hair loss. In this study, researchers describe a case study of one woman’s experience of using Acitretin and hair loss. Since it is a case study, it needs to be taken with a grain of salt. However, if you are taking Acitretin, it is worth considering this drug as a source of your hair loss.
I recommend you review this case study and speak with your doctor and/or dermatologist! This is by no means a diagnosis or cause of hair loss, just one more thing to consider when you are looking at why you might be losing your hair.
