PP405, a topical LDH inhibitor, has shown to stimulate hair follicle stem cell proliferation in humans with moderate hair loss. They are advancing to more detailed trials this year.

Hair loss discussion includes treatments Minoxidil, Finasteride, and RU58841. Users question effectiveness of HMI-115 and consider waiting longer for results.

A user is experiencing hair regrowth after treating vitamin D, B12, and B9 deficiencies, noticing some improvement after 9 months. They are unsure if further improvement will occur or if they have reached the end of progress, with a possibility of androgenetic alopecia (AGA) being suggested.

Akinfenrawr experienced negative side effects from oral finasteride and RU58841, and is seeking alternative hair loss treatments. They discuss various options, including raloxifene, oral dutasteride, liposomal finasteride, Breezula, Pyrilutamide, SM04554, and sulforaphane, but have concerns about efficacy, availability, and cost.

RU58841, an anti-androgenic compound, showed early promise for treating alopecia but faced challenges after its patent in 1997. Despite advancing to Phase II trials, safety concerns and financial struggles led Aventis to abandon its development. Proskelia, which later merged into ProStrakan, couldn't prioritize the drug, leading to its eventual stagnation and failure to reach the market.

The user is experiencing hair loss and is using oral treatments including 5mg minoxidil, 1.1mg finasteride, and 1mg biotin daily. They are considering adding dutasteride and possibly a hair system, while others suggest patience and additional treatments like microneedling.

DUPA and retrograde alopecia may not be solely DHT-based, and a biopsy is crucial for accurate diagnosis and treatment. Treatments mentioned include dutasteride, oral minoxidil, pioglitazone, clobetasol, calcipotriol, ketoconazole, and doxycycline, depending on the specific condition.

PP405 may induce new hair growth but cannot revive completely dead follicles, and its effectiveness on hairlines is uncertain. It is expected to be available by mid-2028, but users are advised to manage expectations and consider using other treatments like minoxidil and finasteride.

A user reported that taking iron polymaltose significantly reduced their hair loss. They also mentioned hair loss due to DHT and asked if hair loss from iron deficiency is permanent or temporary.

Ritlecitinib and PP405 show promise for hair regrowth. Diagnosing the cause of hair loss is crucial before treatment.

RU58841 slowed hair loss for a DUPA sufferer after other treatments like finasteride, dutasteride, and minoxidil failed. Some users reported side effects with RU58841, while others did not experience any.

The user discusses their hair loss experience, exploring various hypotheses including thyroid levels, vitamin D, DHEA, nutritional deficiency, diabetes, seborrheic dermatitis, lack of nutrition to hair follicles, chronic inflammation, female pattern hair loss causes, cortisol, and prolactin levels. They are currently using finasteride, beta-sitosterol, and have tried topical dutasteride and microneedling therapy.

The user experienced hair thinning from chromium and alpha lipoic acid supplements, which stopped after discontinuing them. Someone mentioned this could be telogen effluvium, a temporary condition.

Topical finasteride may have higher systemic absorption and lower efficacy when using a Propylene Glycol/Ethanol formulation compared to the hydroxypropyl chitosan (HPCH) formulation. The safety profile of topical finasteride relies heavily on the HPCH formulation, and using standard solutions might lead to different pharmacokinetics.

Osteopontin, a protein involved in hair growth on moles, may help with hair loss. However, it is also linked to Alzheimer's, cancer, and bone development, so caution is advised.

Missing one day of finasteride is humorously discussed, with suggestions to use additional treatments like dutasteride, RU58841, minoxidil, and microneedling. Some users jokingly suggest shaving the head or traveling for hair restoration.

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.

User has hair loss, finasteride for 5 years not effective. Considers trying dutasteride, minoxidil, or pyrilutamide.

Elevated bile acids can inhibit the enzyme AKR1C2, leading to increased DHT levels, which may accelerate hair loss in those predisposed to androgenetic alopecia. Treatments mentioned include topical minoxidil and finasteride.

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).

Diffuse hair thinning and treatments like finasteride and minoxidil. Early detection and treatment are crucial for effective management.

The efficacy of low doses of finasteride to reduce scalp DHT, and whether studies showing a 61% reduction are reflected in actual results. Replies discussed hair growth as an unintended consequence of minoxidil and finasteride use, as well as self-selective bias, potential side effects, and that studies measure effectiveness by hair count changes rather than DHT inhibition.

Hair loss discussion includes finasteride intolerance and questioning if Pyrilutamide is an alternative. Pyrilutamide not commercially available, but may be tolerable if approved since it's not a 5aR inhibitor.

PP405 updates are seen as vague and lacking substance, causing frustration among users. Some users report positive effects from using minoxidil and dutasteride, while others remain skeptical about new treatments.

TWIST-1 gene's role in hair loss and potential as a treatment target. Inhibiting TWIST-1 may prolong hair growth and reduce hair follicle sensitivity to DHT.

The user has been using 1mg finasteride and 2.5mg oral minoxidil daily for 18 months without success in treating hair loss. They are frustrated with their diffuse androgenetic alopecia and unsure of what to do next.

The user is experiencing diffuse hair thinning despite using finasteride and oral minoxidil, with no hairline recession or bald spots. Suggestions include checking for telogen effluvium, considering a JAK inhibitor for potential autoimmune issues, and conducting further tests to rule out other causes.

The conversation discusses hair loss treatments, focusing on vitamin D and B12 deficiencies, and mentions using finasteride. It also suggests getting a biopsy to differentiate between MPB and other conditions.

IGFBP‐rP1 shows potential for treating androgenic alopecia by influencing hair cycle transitions. Increasing IGF-1 levels may have similar effects to Minoxidil and 5-AR inhibitors in reducing hair loss.

Some individuals experience hair loss despite using treatments like 2.5 mg dutasteride, finasteride, and minoxidil, suggesting sensitivity to DHT or other factors. Various treatments and lifestyle changes are discussed, but results vary, and some consider hair transplants or other solutions.
