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 increase estrogen levels, causing dizziness and nausea. Users discuss adjusting treatment and diet, and explore alternatives for hair loss management.
A user experienced unexpected hormone test results after 7 months on 1mg daily finasteride, noting a decrease in estradiol despite expectations of an increase. Other users suggested that hormone responses can vary and that finasteride might still be effective if DHT levels are within range, while also mentioning factors like circadian rhythm and stress that could impact results.
Genetic factors, enzyme activity, and DHT sensitivity affect individual responses to hair loss treatments like finasteride, minoxidil, and dutasteride. Starting treatments early can slow hair loss, but results vary among individuals.
Switching from finasteride to dutasteride can worsen hair loss for some men due to increased testosterone levels. Topical treatments like RU58841 and Pyrilutamide are suggested to counteract these effects, but individual responses vary.
