Counterfeit minoxidil is a concern, with users suggesting buying from reputable sources like Costco to ensure authenticity. A bleach test can help verify genuine minoxidil.

HMI-115 is a new drug developed by Bioinvent and licensed by Bayer, with mixed opinions on its potential effectiveness. Some users are skeptical and prefer proven treatments like Minoxidil, finasteride, and RU58841.

Painkillers like Aspirin may reduce Minoxidil's effectiveness by inhibiting the enzyme PGHS-1, which is crucial for hair growth. Using NSAIDs that inhibit COX-2 or combining Minoxidil with PGF2/E2 analogues or retinoids may enhance its efficacy.

Pyrilutimide and CB-03-01, two treatments for hair loss, have similar clinical trial results despite different binding affinities to androgen receptors. Factors other than binding affinity, like the time a drug stays bound to the receptor, may influence their effectiveness.

Setipiprant and Fevipiprant are questioned for their effectiveness in hair maintenance, with skepticism due to lack of convincing results beyond vellus hair growth. The user is satisfied with Minoxidil and Finasteride but is curious about the potential of DP2 inhibitors.

The conversation discusses using B6 and Zinc to inhibit 5ar activity, similar to Fin and Dut. Minoxidil is mentioned as a supplementary treatment.

The user mixes their own RU58841 solution and found that increasing the ethanol content improved absorption and reduced scalp itching. A study on minoxidil showed that penetration increased with higher ethanol concentrations, reaching maximum penetration at 90% ethanol.

A Phase 1 update for the HMI 115 clinical trial, which involves 16 participants and is expected to end in July 2023; as well as changes to the recruitment process, including treatment protocols with Minoxidil, Finasteride, and RU58841.

The conversation discusses GT20029, a compound by Kintor Pharma that degrades androgen receptors and is in trials, with potential as a hair loss cure. Another promising treatment mentioned is an antibody that blocks prolactin and has shown positive results in macaques.

Minoxidil works by opening potassium channels, leading to reduced blood pressure and potential side effects like reflex tachycardia. It is used for hair growth and affects blood pressure at high doses.

Hair loss treatments discussed include Minoxidil, Finasteride, and RU58841. HMI-115, a monoclonal antibody drug, is in phase 1 and 2 trials for different conditions, but its availability on the gray market is unlikely due to high production costs.

Hair growth can be induced without stopping DHT, as seen with Minoxidil. HMI115 may work by promoting follicle growth, not targeting the root cause of hair loss (DHT).

The conversation discusses the potential of topical cetirizine (Zyrtec) for hair growth in comparison to minoxidil, noting cetirizine's ability to reduce prostaglandin D2, which inhibits hair growth. Users share mixed experiences with cetirizine for allergies and scalp health, and there's a mention of the risk of dementia with long-term antihistamine use.

The post and conversation are about HMI-115, a potential treatment for hair loss. The conclusion is that HMI-115 is not a 5ar-inhibitor and is instead a prolactin receptor inhibitor. Some users are skeptical about its effectiveness and believe that baldness will still be a problem in the future.

Exploring different treatments for hair loss, such as cosmeRNA and HMI-115 which are small interference messenger RNA that inhibits the DHT receptor and an antibody that binds to the prolactin (PRL) receptor respectively; and researching mechanism and environment of hyperresponders.

Salicylic acid in Nioxin shampoo may reduce minoxidil effectiveness by inhibiting sulfotransferase activity, potentially causing hair loss. Users suggest stopping salicylic acid use or trying alternative treatments like high-concentration tretinoin or medicated minoxidil/finasteride shampoos.

Reishi mushroom is significantly weaker than finasteride for inhibiting 5 alpha reductase, requiring much larger quantities to achieve similar effects. The effectiveness and safety of consuming large amounts of Reishi for hair loss are uncertain.

Minoxidil may inhibit androgen receptors and affect hormonal pathways, potentially explaining its effectiveness in treating androgenetic alopecia (AGA). Users discuss its varying effectiveness on scalp versus facial hair and note fewer side effects with topical use compared to oral.

The efficacy of degrading the androgen receptor through dermal application in DP cells, a delivery system for topical drugs that involves dissolving microneedles, and rosemary oil as an alternative anti-androgen.

A compound called MTP3 from the Monoterpene family was found to be safe and highly effective at treating hair loss by inhibiting the FGF5 gene, but its identity is undisclosed for commercial reasons. No specific treatments like Minoxidil, finasteride, or RU58841 were discussed.

Finasteride not only inactivates the 5a reductase enzyme but also affects the 5b reductase enzyme in a dose-dependent manner, which can impact sexual behavior and brain activity. The user experienced significant hair regrowth and side effects on 1mg of finasteride, which diminished after reducing the dose to 0.5mg, leading to no side effects and further hair improvement.

The user applies a topical solution containing minoxidil, finasteride, dutasteride, retinoic acid, and hydrocortisone to address scalp inflammation and is considering adding cetirizine to the mix. They are calculating the correct amount of cetirizine to add to their formula and have paused this approach to retry oral minoxidil.

Minoxidil was applied to a single miniaturized hair follicle over four months, resulting in less miniaturization but not yet terminal growth. The user used a 5% minoxidil solution, specifically the Regaine brand, and observed changes using a handheld WiFi microscope.

HMI-115, a newly discovered hair loss treatment that could potentially be effective for those with diffuse thinning and telogen effluvium. It is based on prolactin receptor antagonist signaling and has already undergone Phase I trials in women, with potential commercialization by 2027.

The post discusses using a topical tincture containing zinc, azelaic acid, and other ingredients to inhibit 5 alpha-reductase activity for treating hair loss. The user plans to try this natural alternative before using finasteride or RU58841.

The conversation discusses maintaining hair regrowth using minoxidil and finasteride and whether using gt20029, which degrades androgen receptors, would affect this. Fluridil, a similar treatment, can disable over 90% of active androgen receptors.

MCL-1 protein may help maintain hair follicles in the growth phase and prevent miniaturization. There is interest in experimental treatments like exosomes, peptides, or stem cell serums to upregulate MCL-1 for hair loss, especially for those not using minoxidil or finasteride.

Caffeine may interfere with oral minoxidil because caffeine increases blood pressure while minoxidil lowers it. Users discuss potential interactions and effects on hair loss treatment.

Microneedling may enhance hair loss treatment by increasing the effectiveness of topical minoxidil, especially for those lacking the necessary enzyme to activate it. It might also work by triggering growth factors and improving topical absorption.

The conversation discusses combining topical cetirizine with minoxidil for hair loss treatment and inquires about the safety and absorption through the skin, as well as the possibility of adding melatonin.
