Natural vitamins like pumpkin seed oil, saw palmetto, and ecklonia cava are discussed for their potential to lower DHT levels. They may work similarly to finasteride but are significantly weaker.
GHK-Cu is a potent inhibitor of the type 1 5-alpha reductase enzyme in hair follicles, which may reduce hair loss without the side effects associated with type 2 5-alpha reductase inhibitors. The user previously experienced side effects with 5-alpha reductase inhibitors and is considering GHK-Cu as an alternative.
Minoxidil may inhibit androgen receptors and affect hormonal pathways, potentially explaining its effectiveness in treating androgenetic alopecia (AGA). Users discuss its varying effectiveness on scalp versus facial hair and note fewer side effects with topical use compared to oral.
Hair loss treatments, specifically the use of Alfatradiol as an over-the-counter topical 5ARinhibitor that has been shown to be effective in stopping hair loss without side effects. Other treatments discussed include Minoxidil, finasteride and RU58841.
Topical androgen receptor antagonists may not be necessary if 5-ARinhibitors like finasteride or dutasteride effectively reduce DHT levels. Combining a 5-ARinhibitor with a topical androgen antagonist could potentially enhance treatment, but oral use of androgen antagonists is too risky due to severe side effects.
