PP405, developed by Pelage Pharmaceuticals, can reactivate dormant hair follicle stem cells and increase hair growth by 20% in eight weeks, unlike minoxidil or finasteride. However, skepticism remains about its effectiveness and availability, with concerns about funding and the timeline for broader access.

Male pattern baldness (MPB) may be influenced by androgen receptors in scalp hair follicles and potentially poor blood flow. Transplanted hair is not immune to DHT, and factors like inflammation and scalp tension might also contribute to hair loss.

Finasteride may affect male offspring's fertility and hormonal balance, with debates on whether to discontinue use before conception. Some users report no issues, while others highlight the high doses used in rat studies.

Fibrin-based hydrogels support stem cells for hair follicle regeneration, showing promise for alopecia treatment. They enhance cell viability, maintain stemness, and induce hair growth without teratoma formation.

Mallia Aesthetics has developed MAL-838, a hormone-free product derived from sCD83, which stimulates hair growth without disrupting the skin microbiome. sCD83 promotes hair growth by activating hair follicles and preventing cell death, offering a localized treatment without systemic side effects.

ABS-201 shows promise for male hair regrowth by blocking the prolactin receptor, with higher expected efficacy than current treatments. The discussion also covers dosing differences between macaques and humans for hmi115, highlighting a significant dosage disparity.

Hair loss may be influenced by mechanical tension and inflammation, with the hi-c5 protein amplifying androgen effects, leading to follicle miniaturization. Treatments like finasteride, minoxidil, and scalp massages are suggested to manage hair loss.

PTD-DBM is being explored for hair regrowth by targeting CXXC5, with clinical trials expected after pre-clinical studies. Users express anticipation and skepticism about its effectiveness.

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.

Hypoxia may enhance hair growth by stimulating stem cells, but it could also risk fibrosis. Some users humorously discuss extreme methods like choking while using minoxidil, highlighting the need for new treatments.

Significant hair regrowth was achieved using RU58841, minoxidil, and microneedling during a high-dose steroid cycle. The user reported no side effects from RU58841 and plans to continue the regimen.

Fibrin-based hydrogels support stem cells for hair follicle regeneration, showing promise for treating alopecia and wound healing. They enhance cell viability, maintain stemness, and promote hair and tissue regeneration without teratoma formation.

Fibrin hydrogels, when combined with stem cells, can induce hair follicle regeneration and show potential for treating alopecia. The study demonstrated successful hair growth in mice without adverse effects.

TDM-105795 showed promising hair growth results, with higher efficacy than placebo and minimal side effects. It activates dormant hair follicle stem cells and may maintain gains without immediate loss, unlike minoxidil.

DLQ01, a prostaglandin F2α analog, shows promise for hair growth by directly stimulating PGE2/PGF receptors without needing conversion, and can be combined with minoxidil and retinoids like tretinoin for enhanced effectiveness. Minoxidil's efficacy may be reduced by COX-1 inhibitors, but using prostaglandin analogs like Latanoprost or Bimatoprost can help maintain its effectiveness.

A user's father experienced hair regrowth and other health improvements after two IV exosome treatments. The user also had four rounds of exosome therapy, noting significant hair regrowth and relief from headaches, but no change in gray hair.

Relaxation may promote hair growth by reducing corticosterone, which affects hair follicle stem cells. Corticosteroids are used for alopecia areata, but their long-term use for androgenic alopecia is uncertain.

Amplifica raised $26 million to advance its injectable treatments for hair growth. The funding will support the clinical development of their novel therapies.

Estrogen injections significantly improved hair growth, particularly on the crown, after stopping finasteride. Monotherapy with estrogen led to hairline improvement, but also caused sterility and potential feminization effects.

The conversation discusses using microneedling with growth factor serum, PRF injections, dutasteride, oral and topical minoxidil, and topical exosomes to treat hair loss, particularly on the crown. OP plans to microneedle twice a month and seeks feedback on Korean growth factor serums.

Balding scalps have more androgen receptors, leading to increased TGF-beta, which causes blood vessel loss and hair follicle miniaturization. Blocking androgen signaling and TGF-beta may help prevent hair loss.

The conversation discusses hair loss linked to BDNF-increasing nootropics like Semax and Lions Mane. Suggested topical treatments include capsaicin, beta-glucan, and ginseng to counteract TGF-B activation.

Pelage is moving to Phase III clinical trials for PP405, a hair loss treatment, with results to be presented at a medical meeting. Users express skepticism and hope, comparing it to existing treatments like Minoxidil and finasteride, while discussing the potential for new hair growth in previously bald areas.

A user proposed genetically engineering scalp stem cells to stop androgen receptors from causing hair loss. Others discussed the feasibility, existing research, and potential issues with this approach, including targeting the correct cells and unintended effects.

The user experienced new hair growth after switching from oral finasteride to topical RU58841 with minoxidil and undergoing stem cell therapy. They noticed new hairs at the hairline and temples, but are unsure which treatment is responsible.

Pelage is recruiting for phase 2 trials, showing promise for treating bald regions. The discussion highlights its potential effectiveness based on its mechanism of action.

An 18-year-old has been using minoxidil and finasteride for hair loss since age 15, recently adding dutasteride and GHK-Cu, but sees no significant improvement and is considering a hair transplant. Concerns are raised about using hormone suppressors at a young age, with suggestions to explore other treatments like dermarolling, diet changes, and checking for deficiencies.

Pelage is developing a topical hair follicle stem cell therapy, PP405, for non-scarring alopecias like androgenetic alopecia, with Phase III trials planned and a potential market launch by 2027. The treatment may not require continuous use after initial regrowth.

PP405 targets hair follicle stem cells differently than exercise-induced lactate, suggesting exercise alone may not replicate its benefits. Minoxidil and finasteride are recommended alongside exercise for hair regrowth, with additional suggestions like spicy food and infrared exposure.

Finasteride's effectiveness and side effects may vary based on male phenotypes, with some users noting differences in response related to body and facial hair characteristics. Some users report success with lower doses, while others experience side effects, suggesting individual variability in response to the treatment.
