Finasteride can increase total testosterone and potentially raise estrogen levels, leading to side effects. Biotin in combined tablets can falsely elevate thyroid hormone levels in blood tests.

A user experienced increased testosterone and estradiol levels after starting finasteride/dutasteride and is asking if these levels will return to normal over time. The conversation focuses on whether these changes are temporary.

The user reported high testosterone and estradiol levels within range, but unexpectedly high DHT levels after using finasteride and dutasteride for hair loss. Another person suggested the dutasteride might be fake or a bad batch and recommended using the branded Avodart.

The conversation discusses using finasteride topically for hair loss and concerns about potential side effects like feminization and impact on muscle growth. One person shared their experience with finasteride, indicating it increased testosterone and did not prevent them from gaining muscle or strength.

People on testosterone replacement therapy (TRT) with aggressive androgenetic alopecia (AGA) discuss using Dutasteride or Finasteride, sometimes combined with topical treatments like RU58841 or CB-03-01 (Breezula), to prevent hair loss. Concerns about side effects and costs of certain treatments are mentioned, with one individual sharing their experience of slowed hair loss using Finasteride alone.

A user with low testosterone and mild gyno is considering finasteride for hair loss. Others suggest consulting an endocrinologist first and share experiences of finasteride not worsening gyno.

Clotrimazole may inhibit testosterone better than Ketoconazole. The user considers applying Clotrimazole cream on the scalp for hair loss.

A user reported that after using a topical mix of finasteride and minoxidil, their DHT levels decreased, testosterone and estradiol levels lowered unexpectedly, and they are considering vitamin D3 supplements due to deficiency. They apply the mix 3-4 times a week and use minoxidil on other days. Another user commented that finasteride typically increases testosterone, not decreases it.

Spironolactone is more potent and lowers testosterone and DHT, while dutasteride only impacts DHT. For female hair loss, checking hormones and considering treatments like oral minoxidil, spironolactone, or topical minoxidil is recommended.

A user reported a 50% increase in testosterone after 18 months of taking dutasteride for hair loss. The conversation includes skepticism about the reliability of single testosterone tests and questions about estrogen levels.

Hair loss can be linked to low testosterone, affecting DHT and estrogen levels. Treatments discussed include increasing testosterone, using Finasteride, and applying estrogen cream.

RU and Pyri block androgen receptors to prevent hair loss but may also hinder hair regrowth since they prevent testosterone, which can stimulate hair growth, from binding to these receptors. The user is questioning if this understanding is correct.

The conversation discusses the fluctuation of testosterone levels in men under 40 and the difference between serum DHT and scalp DHT. It also mentions that DHT levels are higher on Dutasteride than on Finasteride, which is unusual.

Trans woman experiencing thinning hair despite low testosterone and finasteride use seeks possible causes and solutions. Current treatments include finasteride, spironolactone, estradiol, vitamins, and microneedling; minoxidil not tried due to concerns about dependence and side effects.

Trans woman experiences hair thinning despite low testosterone and treatments like finasteride and microneedling. Possible causes discussed include past eating disorder and current stack of medications and supplements.

Breezula protects hair follicles from both testosterone and DHT, unlike finasteride, which only protects against DHT. This could potentially lead to significant hair regrowth, similar to results seen in transgender individuals using hormone blockers.

The user experienced excessive scalp oiliness and high testosterone levels after switching from finasteride to dutasteride. They plan to manage their condition with finasteride and are considering spironolactone to reduce testosterone and restore dry skin.

A 30-year-old man experienced significant hair loss after starting testosterone replacement therapy (TRT), which did not improve with daily finasteride and minoxidil. He is considering restarting TRT and is seeking advice on using pyrilutamide or RU58841 to prevent further hair loss.

The conversation discusses the use of 12.5mg cyproterone every other day for hair loss. There's a concern about reducing testosterone potentially increasing DHT and negatively affecting hair.

A 31-year-old male with low normal-range testosterone and DHT is experiencing significant hair loss from the front scalp. He has tried Minoxidil, vitamin D3 and B12 supplements, and exercises regularly but is still seeking the root cause and effective treatment.

The conversation is about using topical finasteride or dutasteride with a testosterone and NPP cycle for hair loss. The planned treatment includes microneedling, minoxidil, pyrilutamide, and dutasteride applied topically.

The conversation discusses concerns about starting finasteride with low testosterone levels, with one person suggesting finasteride might increase testosterone and decrease DHT, and another advising to pay attention to thyroid-stimulating hormone (TSH) levels.

Gym and creatine can cause hair loss by increasing testosterone and androgenic activity. DHT blockers may help some, while others need androgen suppression with topical AA like RU or Pyri.

The user, on testosterone replacement therapy, found finasteride and minoxidil ineffective for hair loss. They are trying a new topical gel with dutasteride, tretinoin, and a higher concentration of minoxidil, and plan to document the results.

The user received hormone test results showing normal estradiol and testosterone levels, low SHBG, and normal free androgen index. They are considering starting finasteride but are concerned due to being slightly overweight.

Peppermint oil may promote hair regrowth by decreasing scalp testosterone and DHT levels. Other herbs in the Mint family, like spearmint and rosemary, might also reduce testosterone.

Pyrilutamide and RU58841 are androgen receptor antagonists that block receptors without significantly reducing testosterone or DHT levels. Any indirect effect on androgen levels is likely negligible.

Topical dutasteride may not significantly reduce hair loss and could potentially increase testosterone, leading to further hair loss. Users report side effects like mood changes, sleep issues, and severe side effects, with no significant progress in hair regrowth.

Being overweight may increase finasteride side effects due to higher aromatase activity converting testosterone to estradiol. Maintaining a healthy weight could reduce these side effects.

Trans women discuss using finasteride and dutasteride for hair loss and whether to continue after testosterone suppression. One user reduced dutasteride dosage after achieving undetectable testosterone levels.
