Dutasteride isn’t working confirmed by test.

Finasteride/Dutasteride 4/22/2025

After 11 years on Finasteride, a user's hair is thinning again, suggesting hair may become more sensitive to DHT with age. They plan to introduce Dutasteride once a week, as they cannot tolerate Minoxidil.

The effects of Finasteride, a drug used to treat hair loss, prostate problems and other conditions. The post by iaskedadoctor describes the conversations they had with a Urologist about the effects of the drug on DHT levels throughout the body, how lower doses are beneficial in reducing side effects, how erectile dysfunction can be psychological as well as physiological, how morning erections are not necessarily important, and how persistent side effects appear to be rare. People also shared their experiences with taking Finasteride for hair loss, including potential side effects such as reduced ejaculate force and development of man boobs.

A woman is concerned about her husband's hair thinning and researches treatments like finasteride and minoxidil. He decides against medication due to potential side effects and plans to shave his head if necessary.

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.

The conversation provides a guide on using finasteride for hair loss, suggesting to start with a quarter of a 1mg pill daily after ensuring estradiol levels are within a specific range, and potentially increasing the dose if no side effects occur. It also recommends supplements like DIM, Calcium d-glucarate, and Zinc to manage high estradiol levels and side effects from finasteride.

A user was prescribed 5mg of Finasteride daily for hair loss, which is a higher dose typically used for prostate issues. Many suggest using a pill cutter to reduce the dose to 1mg or less per day, as it is more cost-effective and equally effective for hair loss.
