5 AR inhibitors may not be enough for men with more “severe” genetic hair loss condition.
5 AR inhibitors don´t protect the hair follicles´ androgen receptors from androgens in general.
DHT leftovers, testosterone and other “weaker” androgens can still cause hair loss by individuals with genetic hair loss condition using Finasteride already.
5 AR inhibitors are not able to “block” the androgenic effects of natural androgens or steroidal androgens.
Potential side effects related to low sexual desire, low libido, decreased sexual arousal , weak erections by small percentage of users were observed by 5 AR inhibitor users. Statistically only 1-2% of men experience side effects from drugs like Finasteride (slightly higher side effect profile by Dutasteride).
Make sure you do your due diligence on PFS (post finasteride syndrome)– mixture of psychologically- and sexually-related side effects, depression, suicidal thoughts, anxiety.
PFS suggests that these side effects may also persist after patients discontinue the use of any 5 AR inhibiting agent like Finasteride or Dutasteride.
