PP405 is a promising new treatment for hair loss. It performs three actions in one, potentially offering a cure.

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.

PP405 shows promise in activating dormant hair follicles and increasing hair counts but lacks detailed efficacy data compared to minoxidil and finasteride. Opinions are mixed, with some optimism and skepticism about its effectiveness.

A user experienced high estrogen levels after 10 months of taking 1mg oral finasteride but is happy with hair regrowth. They are considering switching to topical finasteride and are also taking DIM and Zinc supplements.

User shared progress pictures after 2 months of using 5% topical minoxidil, microneedling, and recently adding 0.01% topical finasteride. The minoxidil solution also contains caffeine, azelaic acid, retinol, adenosine, biotin, and niacinamide.

Pelage Pharmaceuticals raised $120M for their hair loss treatment, PP405, showing strong investor confidence despite limited data. There is skepticism about its efficacy and long-term effects compared to treatments like GT20029.

Stopping finasteride may reduce water retention or alter fat distribution, leading to a leaner face. Hormonal changes, like reduced DHT or increased estrogen, could cause these effects.

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.

Hair loss discussion includes topical latanoprost and melatonin. Users share regimens and products used for treatment.

A user reported that after experiencing hair thinning, they started using finasteride in 2024 and later began GHK-Cu peptide injections in March 2026, which they believe stopped their hair loss and made their hair feel thicker. The user shared their experience despite receiving criticism for not solely endorsing finasteride.

PP405 may promote short-term hair growth by pushing follicles into the growth phase, but concerns exist about long-term effects due to lack of rest phases. Users discuss various treatments like finasteride, minoxidil, spironolactone, alfatradiol, and investigational drugs like KX-826 and GT20029 for hair maintenance and regrowth.

Microneedling combined with latanoprost may convert vellus hairs to transitional or terminal hairs. The user suggests using oral minoxidil to increase vellus hair, then applying a high concentration of latanoprost with microneedling for conversion.

User tried Toppik hair fibers and liked the results, but hairspray darkened the color. They asked for advice on Toppik brand spray or alternatives that don't darken hair color.

Microneedling can cause sneezing and eye tearing due to nerve stimulation, particularly near the temples and forehead. Some users find it lessens over time, while others prefer using finasteride and minoxidil for hair growth.

The user experienced increased hair shedding after adding tretinoin to their regimen of finasteride, minoxidil, and dermarolling, but noticed new vellus hairs appearing. They plan to restart tretinoin more gently, as some users suggest shedding indicates treatment effectiveness, while others warn it may cause severe thinning for a minority.

Hair loss treatments discussed include microneedling, minoxidil, tretinoin, finasteride, dutasteride, pumpkin seeds, saw palmetto, and scalp massage. The consensus is that finasteride or dutasteride is necessary for significant regrowth, while other methods may only slow hair loss.

PP405 is a new hair loss treatment advancing quickly in trials, generating excitement and skepticism about its effectiveness and marketing claims. Some see it as a potential alternative to minoxidil and finasteride, but concerns about long-term effects and the need for DHT blockers persist.

Veradermics' new hair loss treatment, VDPHL01, is likely a modified release oral minoxidil, which has received $75 million in funding for clinical trials. Despite skepticism about investing in a known treatment, some believe it could offer improved efficacy and reduced side effects.

The user experienced a receding hairline and tried minoxidil, which may have slowed the process but caused puffy eyes. They are hesitant to use finasteride and suspect oily dandruff might be an aggravator.

Topical melatonin may help reduce hair loss and increase hair thickness in people with androgenetic alopecia (AGA), with some studies showing positive results. It can be mixed with minoxidil for application, and its effectiveness might be enhanced when used with micro-needling, but results may vary among individuals.

The conversation discusses the potential benefits of adding Vitamin B6 (P-5-P) to topical hair loss treatments like RU58841, finasteride, or minoxidil. The user suggests that Vitamin B6 might enhance these treatments by naturally lowering scalp prolactin.

Topical minoxidil can cause water retention, making the face appear swollen. Switching from liquid to foam and reducing application frequency may help; using dandelion root extract as a diuretic is also suggested.

Dr. Bloxham's trial is testing verteporfin on hair transplant patients to see if it can improve hair regrowth in treated areas. People are discussing the potential for follicle regeneration, expected results timeline, and concerns about side effects like cancer.

The user has been experiencing prolonged hair shedding despite using Dutasteride, Minoxidil, and topical Finasteride, with blood tests showing high free testosterone and low SHBG. Suggestions include adjusting Minoxidil dosage, considering topical anti-androgens like RU58841, and addressing metabolic factors to increase SHBG.

A 23-year-old male is experiencing diffuse hair loss and miniaturization, possibly due to high IGE levels after using tofacitinib. He seeks advice and has not yet consulted a dermatologist.

Hair loss discussion includes PRP procedures. Some say it's not worth the money.

Extended-release oral minoxidil (VDPHL01) shows promising results for hair growth with improved safety, achieving significant hair count increases and minimal side effects compared to placebo. The treatment is designed to maintain effective concentrations while reducing side effects, making it a safer option for those who cannot tolerate standard minoxidil.

PP405 is seen as promising but uncertain, with users advised to continue using existing treatments like minoxidil and finasteride. Concerns include its cost, availability, and interaction with hair transplants, while some hope it could complement current treatments.

GHK-Cu injections led to unexpected temple hair growth for someone who had been using minoxidil and finasteride for over a decade. The user plans to continue using GHK-Cu and experiment with a DIY AHK-Cu serum.

The user experienced an elevated heart rate from using topical Minoxidil and discontinued its use. They found that adding a daily protein shake helped with telogen effluvium.
