Dutasteride may cause chronic infertility by reducing semen volume and motility, with concerns about irreversible prostate fibrosis. Users consider switching to finasteride or using treatments like minoxidil and microneedling, weighing hair preservation against fertility.
Dutasteride at 2.5mg is considered a potential hair loss cure due to its DHT-blocking ability, but there are concerns about side effects and individual responses. Minoxidil, finasteride, and RU58841 are also discussed, with mixed opinions on their effectiveness and safety.
Dutasteride is less commonly prescribed for hair loss because it is not FDA-approved for this purpose, unlike finasteride, which is more accessible and preferred due to fewer side effects. Dutasteride may be more effective in reducing DHT but has a longer half-life and potentially more significant side effects.
Dutasteride is unlikely to worsen hair loss; shedding is often temporary. Other factors like inconsistent use, placebo effect, or additional treatments may influence perceived results.
Dutasteride might be better for hairline due to varying levels of 5AR activity in scalps. Genetic tests can determine if finasteride is enough or if dutasteride is needed.
