Hair loss is linked to cellular physiology and the IGF-1 to TGF-B1 ratio, not just androgen sensitivity. The theory lacks evidence, while finasteride and minoxidil are effective treatments.

PP405 is a promising experimental topical treatment for alopecia that reactivates dormant hair follicles by targeting cellular energy, with large-scale trials planned for 2026. While it shows potential, it cannot regenerate permanently destroyed follicles, making hair transplants the only guaranteed solution for advanced baldness currently.

PP405's effectiveness in increasing hair density is questioned due to a small sample size, despite investment from Google Ventures. Users express skepticism and suggest waiting for more conclusive results.

The user experienced male pattern baldness starting at 18, tried finasteride with no success, and switched to dutasteride, which halted hair loss. Minoxidil had no effect for them, while their brother, who didn't use AR inhibitors, maintained a juvenile hairline and successfully grew a beard with minoxidil, highlighting the unpredictable nature of genetics in hair loss and treatment response.

User is experiencing hair thinning and sebum overproduction after starting finasteride and a hair growth supplement containing biotin, iron, zinc, and calcium. They suspect the finasteride might be fake but have noticed a side effect of watery semen.

PP405 is considered a promising potential cure for hair loss, with phase 2 trial results expected in February 2025. Hair cloning is also discussed as a potential ultimate solution, despite significant scientific challenges.

PP405 shows potential for hair growth, with 31% of advanced balding men experiencing over 20% increase in hair density in 8 weeks. However, skepticism persists due to selective data presentation and lack of long-term results, with comparisons to treatments like minoxidil and finasteride.

A 34-year-old woman is experiencing diffuse hair loss and irregular periods, possibly due to long-term spironolactone use. She is considering minoxidil and finasteride for treatment and seeking medical advice for androgenic alopecia and hormonal imbalances.

A potential new hair loss treatment, HMI-115, and the possibility of discontinuing finasteride in favor of it. The conversation also includes discussion about other benefits of using finasteride.

The user experienced rapid diffuse hair thinning for five years despite no signs of AGA or miniaturization. They tried finasteride and oral minoxidil without success and have checked thyroid, iron, and vitamin D levels.

Federal funding cuts have delayed PP405 research, affecting hair loss treatment progress, though clinical trials will continue. The discussion highlights PP405's potential compared to minoxidil and finasteride and stresses the importance of government-funded research.

Vitamin D and B9 (folic acid) deficiency can cause hair loss. The user started taking supplements but hasn't noticed significant changes yet.

A woman discovered her long-term hair loss was due to undiagnosed anemia, with ferritin levels as low as 9. After starting iron supplements, she saw significant hair regrowth, especially in previously bald areas, though some spots remain unchanged.

Some people don't see results with FDA-approved hair loss treatments like finasteride or minoxidil due to underlying issues. The video suggests addressing these issues, especially if there are atypical symptoms or other health conditions.

The conversation discusses severe hair shedding and thinning, with the original poster using finasteride, oral minoxidil, and other supplements without improvement. The discussion highlights the possibility of telogen effluvium and the importance of addressing potential underlying health issues, such as stress and gut health, rather than assuming diffuse unpatterned alopecia (DUPA).

The user tried Minoxidil without success, and Finasteride worked but caused sexual side effects even at a very low dose. They are seeking alternative treatments for hair loss as they cannot tolerate anti-androgens and are also in therapy for mental health.

A 20-year-old male has been experiencing hair loss for three years due to a vitamin D deficiency and has seen no improvement after 3.5 months of taking supplements. Another person suggested that if the hair loss follows a pattern, it might be regular baldness rather than due to the deficiency.

Vitamin D deficiency can hinder hair recovery, and addressing it may help with hair loss. Hair loss may result from various issues like excess DHT, vitamin deficiency, or scalp inflammation.

Person 1, with slow hair loss, might need less finasteride than Person 2, who is balding rapidly. The suggested doses are 0.25 mg finasteride three times a week for Person 1 and 1 mg daily for Person 2.

High DHEA levels may contribute to hair loss by increasing DHT in hair follicles, potentially explaining why finasteride is ineffective for some. Treatments like high-dose dutasteride and RU58841 are suggested, but the underlying cause, such as adrenal issues, should be investigated.

A 19-year-old female is experiencing significant hair loss, with symptoms including alternating hair colors and thinning body hair. She seeks advice on coping and potential treatments, with suggestions to consult a dermatologist and check thyroid and hormone levels.

The user is experiencing hairline thinning despite using finasteride, minoxidil (solution and foam), dermastamping, and tretinoin. They suspect minoxidil or tretinoin might be causing the issue but are unsure.

HMI 115 did not work as expected for hair regrowth in humans, unlike in macaque monkeys. There is anticipation for further research on prolactin's role in hair loss, with expectations that pharmaceutical companies will likely solve this before universities.

Lactic acid is not effective for hair growth when applied topically. JXL069, finasteride, and minoxidil are suggested as alternative treatments.

KY19382, a promising compound for hair loss, is not widely discussed or used. One user is currently testing it and plans to share results in a few weeks.

The conversation is about hair loss and correcting vitamin deficiencies, specifically D3, B12, and folic acid. The user is considering if these deficiencies impact hair growth and mentions starting supplements.

A 20-year-old is experiencing hair thinning due to vitamin D deficiency and has completed a vitamin D prescription without seeing improvement. Suggestions include waiting a few months for potential regrowth or considering treatments like minoxidil or finasteride for androgenetic alopecia.

The user is concerned about having a straight, low hairline after a hair transplant and is unable to take finasteride due to high estrogen and prolactin levels. They have used minoxidil with limited success and are considering further transplants to lower the hairline, while others suggest the risks of using up donor hair too quickly.

PP405 is discussed as a potential hair growth stimulant, possibly more effective than minoxidil, but not a cure for hair loss. There is skepticism about its ability to regrow "deadzones," and concerns about its impact on those with hair transplants.

Vitamin D deficiency is linked to hair loss, and supplementation with vitamin D can improve conditions like androgenic alopecia and telogen effluvium. Users discussed various dosages of vitamin D, emphasizing the importance of getting blood tests to determine the appropriate amount.
