Finasteride can cause side effects like erectile dysfunction and decreased libido, possibly due to increased estradiol from testosterone aromatization, especially in those with higher body fat. Side effects vary widely and may also be influenced by genetic factors or neurosteroid inhibition.

After 13 years on finasteride, OP is experiencing reduced effectiveness and has started taking 0.5 mg of dutasteride weekly, noticing nipple sensitivity as a side effect. OP plans to increase the dutasteride dosage and retest hormone levels, while others suggest adjusting the dosage or trying different forms of dutasteride.

PP405's phase 2a trial results were presented, focusing on safety and pharmacokinetics, with a future meeting planned to share the full dataset. The trial includes a randomized controlled portion and an open-label extension, with no indication of phase 2B completion.

The user has been using finasteride, minoxidil, and ketoconazole for hair loss, showing good progress without significant side effects. They plan to have a hair transplant in March and hope to eventually stop using oral minoxidil.

Kintor's phase III trial for pyri (KX-826) showed promising safety and efficacy results, with no drug-related sexual dysfunction reported. Users discussed their experiences with pyri, Minoxidil, Dutasteride, and concerns about the validity of the study results.

The conversation discusses that dutasteride may be more effective than finasteride for frontal hair loss due to higher 5ar Type 1 enzyme activity in that area. Some users question the validity of this information, while others confirm it with additional sources.

PP405 may damage hair follicles if used long-term, suggesting cycling might be necessary. Combining it with finasteride could help maintain hair growth.

GT20029 is a topical treatment that degrades androgen receptors to prevent hair thinning and loss, potentially offering fewer side effects than systemic treatments like finasteride. Concerns include its impact on hair texture and potential systemic effects, with market availability speculated in 3 to 5 years.

People on finasteride or dutasteride cannot donate blood due to the risk of birth defects if the blood is given to a pregnant woman. It's advised to stop finasteride for a month and dutasteride for six months before donating.

The user has high DHT levels despite using dutasteride, which may not be effective due to potential damage or spoilage. They are considering a hair transplant if DHT levels don't decrease after two years.

Micronutrient testing and deficiencies related to hair loss, particularly androgenetic alopecia (AGA). Discussion includes the impact of iron, selenium, zinc, copper, folate, B12, vitamin E, vitamin D, amino acids, and fatty acids, alongside treatments like dutasteride or finasteride.

The user experienced severe side effects from finasteride, including hormonal imbalances and cognitive issues, leading to a recommendation to stop its use. They plan to follow up with tests to rule out a pituitary tumor and are considering topical treatments as alternatives.

GT20029 is discussed as a potential treatment for androgenetic hair loss by targeting androgen receptors, unlike finasteride which reduces DHT broadly. Concerns include its effectiveness, genetic variations in androgen receptors, and availability, with some skepticism about its potential as a true alternative.

A user shared their experience with hair transplant success and stopping finasteride due to side effects like brain fog. They are content with potential hair loss and prioritize health over hair maintenance.

The user is concerned about hair loss despite using oral finasteride, oral minoxidil, and topical minoxidil. They are seeking advice on additional blood tests to identify potential causes.

The conversation discusses the potential use of HMI 115 for hair loss and whether it could replace or be used alongside finasteride, minoxidil, and RU58841. The user is experiencing scalp inflammation and continued hair shedding despite using finasteride for 8 years.

Saw palmetto's fatty acids, particularly lauric and linoleic acids, inhibit enzymes linked to hair loss, while sterols like beta-sitosterol are less effective due to poor absorption. The conversation questions which specific compounds in saw palmetto contribute to its anti-androgenic effects.

The user has been using liposomal topical finasteride since late 2022, progressively increasing the dose, but DHT serum levels remain largely unchanged. Despite using finasteride, minoxidil, microneedling, and ketoconazole, hair condition has neither improved nor worsened.

The conversation discusses whether to get blood work before starting finasteride, with opinions varying on its necessity. One user reported developing gynecomastia after using finasteride, despite trying Anastrozole to manage estradiol levels.

Using a face serum with 1% copper peptides (ghk-cu) on the scalp as an adjunct to finasteride and minoxidil for hair growth and scalp health. The user is unable to find a specific hair serum with ghk-cu locally.

A user with high pre-finasteride estrogen levels is asking if they need to normalize their hormone levels before starting finasteride and whether they should postpone dermarolling until they begin finasteride. The user is 21.5 years old.

A user is concerned that finasteride isn't working for their hair loss, questioning if it's due to male pattern baldness or low iron levels. They are advised to take finasteride daily and get blood work done.

Pyrilutamide shows minimal systemic absorption with low plasma levels and no accumulation, suggesting it's unlikely to cause systemic side effects. However, full results are not yet published in scientific journals.

User experienced severe allergic reactions and liver issues after a hair transplant, likely due to antibiotics and medications. Despite trying Minoxidil, the user faced further complications and is now seeking medical advice for potential future transplants.

PP405 is a new hair loss treatment in phase 2 trials that may promote hair growth by increasing lactate production and activating hair follicle stem cells. It could potentially replace hormone-disrupting treatments like Minoxidil and finasteride.

The conversation is about someone planning to start finasteride or RU58841 for hair loss and wanting to know which hormones to test beforehand. They found a package for testing testosterone, free testosterone, estradiol, and DHT, and are asking if these tests are enough.

A 30-year-old male has been on finasteride/dutasteride for 3 years, with stable but still receding hairline, and blood tests showing high total testosterone but normal DHT and free testosterone levels. Despite challenges in gaining muscle, he maintains a good physique with a consistent lifting routine and recently improved results with creatine.

N-Acetyl-Cysteine (NAC) was found to improve hair parameters in men with early-onset androgenetic alopecia, showing increased terminal hair count and decreased vellus hair count, with good tolerability. NAC, used alone or with minoxidil, may help due to its antioxidant properties, though its effectiveness can vary among individuals.

The user experiences hair loss and scalp reactions after eating certain non-organic foods, leading them to adopt an all-organic diet which has stabilized their hair condition. Suggestions include using liver-supporting herbs and considering gut health issues like histamine sensitivity.

DHT may inhibit hair growth by affecting mitochondrial function, leading to hair follicle miniaturization. Treatments like minoxidil and PP405 may promote hair growth by altering metabolic pathways, potentially counteracting DHT's effects.
