Oral minoxidil is effective for hair loss but can cause cardiovascular side effects, such as pericardial effusion, especially in those with genetic predispositions. Starting with low doses and monitoring cardiovascular health are advised to reduce risks.
Dutasteride may not effectively stop scalp hair loss and can cause thinning of facial and body hair, including eyebrows. Users suggest considering other causes like autoimmune conditions or vitamin deficiencies and exploring treatments like finasteride or minoxidil.
Dutasteride takes 1-3 months to affect scalp DHT levels, not just a week. The prostate absorbs Dutasteride faster than the scalp due to different vascular networks and enzyme densities.
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.
The user plans to switch from dutasteride back to finasteride due to worsening hair loss, possibly due to increased scalp testosterone. Others report mixed results with both treatments, showing individual variability.
