Topical finasteride is considered safer for the liver than oral finasteride due to less systemic absorption, but regular liver function tests are advised. The user is concerned about liver health due to a history of NAFLD and is exploring topical finasteride as a safer alternative.
RU58841 is used topically to prevent hair loss by blocking DHT, with suggestions to drink grapefruit juice, take breaks, avoid microneedling, and use lower concentrations to reduce side effects. Users discuss applying it at night to minimize systemic absorption.
A 23-year-old is considering using a topical solution of Finjuve (finasteride and minoxidil) at a reduced dosage of 0.2/0.4mg to treat crown thinning while minimizing side effects. Applying 0.1-0.2 mL is suggested to lower systemic absorption and effectively reduce DHT on the scalp.
Using both oral and topical minoxidil is likely safe, but be cautious of increased systemic absorption. The best tretinoin dosage to enhance minoxidil effectiveness is not specified.
The conversation is about whether it is safe to take Xeljanz, a JAK inhibitor, while also taking finasteride for hair loss. The concern is that Xeljanz weakens the immune system, which could be risky.
