Glossary Steroidal Antiandrogens

block male hormone effects to treat hair loss

Steroidal antiandrogens are a class of medications that block the effects of androgens, which are male sex hormones like testosterone. They are used to treat conditions such as prostate cancer, androgenic alopecia (hair loss), and severe acne by reducing the influence of these hormones on the body. These drugs work by binding to androgen receptors, preventing androgens from exerting their effects.

community How to Keep Your Hair on Steroids

25 upvotes 2 years ago

To minimize hair loss while using steroids, use finasteride or dutasteride and apply topical anti-androgens like RU58841. Avoid high doses of hair-toxic steroids; prefer testosterone, nandrolone, and boldenone.

community Has anyone find a way to stop/limit ru58841 to go systematic ?

in Finasteride/Dutasteride 4 upvotes 1 year ago

RU58841 is a strong non-steroidal antiandrogen for hair loss but may cause cardiovascular issues in some users. Alternatives like Pyrilutamide and Breezula are suggested due to better safety profiles and lower systemic risks.

community Dutasteride vs Finasteride and Steroid

in Progress Pictures 87 upvotes 11 months ago

Dutasteride is preferred over finasteride for hair loss due to fewer side effects. Combining dutasteride with minoxidil and RU58841 is effective for hair regrowth, even during steroid use.

Can hydrocortisone be used together with other treatments like minoxidil or steroid injections? Clinicians do use a mild steroid cream to settle the scalp irritation minoxidil can cause, but no verified trial tests hydrocortisone added to minoxidil or to corticosteroid injections, and prolonged scalp use risks skin thinning — combining it is a decision to take with a prescriber.
