The user experienced male pattern baldness starting at 18, tried finasteride with no success, and switched to dutasteride, which halted hair loss. Minoxidil had no effect for them, while their brother, who didn't use AR inhibitors, maintained a juvenile hairline and successfully grew a beard with minoxidil, highlighting the unpredictable nature of genetics in hair loss and treatment response.
Hair loss is primarily genetic, and nutrient deficiencies are unlikely to be the cause. DHT inhibitors can slow hair loss, but concerns about side effects are common.
Finasteride can cause side effects like erectile dysfunction and decreased libido, possibly due to increased estradiol from testosterone aromatization, especially in those with higher body fat. Side effects vary widely and may also be influenced by genetic factors or neurosteroid inhibition.
Genetic variations influence how people respond to dutasteride for hair loss, with some benefiting more from finasteride. Dutasteride is effective for most, but genetic differences may cause it to be less effective for some.
Finasteride and Propecia are essentially the same, but some people may respond differently due to inactive ingredients. If cost is not an issue, Propecia is preferred due to better quality control and consistent results.
