Corticosterone inhibits GAS6, affecting hair follicle stem-cell activity, with potential implications for stress-related hair loss. Ashwagandha and Vitamin K are suggested for reducing cortisol, but their effectiveness is debated.

The user experienced significant hair loss on the scalp, eyebrows, eyelashes, and pubic area, along with itchy, flaky skin and red patches. They have a history of eczema and dermatitis and suspect that stopping shampoo use and taking Ritalin may have contributed to the issue.

PP405, a topical treatment, shows promise for hair growth by activating inactive follicles, with 66% of participants experiencing positive results. The treatment is well-tolerated and may proceed directly to Phase 3 trials, offering a potential alternative to minoxidil and finasteride.

The conversation discusses the importance of scalp skin barrier health in hair follicle cycling, suggesting treatments like ceramides or niacinamide to support hair growth. It also mentions the use of finasteride for hair loss.

The user is using RU58841 for hair regrowth on the temples and is considering adding minoxidil. They are questioning the potential for vellus hairs to develop into fuller hair and the possibility of reactivating dormant follicles.

The user changed their hair loss treatment in October/November, experienced increased shedding, and now sees no new hair growth, with a worsening condition and a possible bald spot. They also have severe seborrheic dermatitis, which may be affecting their scalp and hair loss.

The conversation discusses a patent filed by Shiseido for cloning Dermal Papilla (DP) cells to treat hair loss. The method involves using viral vectors to maintain the cells' growth-inducing properties, differing from Replicel's approach with Dermal Sheath Cup (DSC) cells.

Human pluripotent stem cells have been used to create hair and skin, potentially offering a new solution for baldness. A user also mentioned starting finasteride but experiencing unexpected hair thinning.

He Shou Wu (Fo Ti) extract was found to prolong the hair growth phase, inhibit 5-alpha-reductase (like finasteride), reduce androgen receptors, and increase growth factors, potentially outperforming minoxidil in recovering hair follicle size after DHT exposure. Two compounds, emodin and TSG, are identified as responsible for these effects and warrant further investigation.

RU58841 is discussed as a treatment that stops scalp itching when used with finasteride or dutasteride. The user is considering trying RU58841 due to persistent itching despite using the "big 3" treatments.

The conversation discusses experiences with hair loss treatments containing RootBioTec and Anagain. Users share their results and compare these treatments to Minoxidil, finasteride, and RU58841.

Selenium sulfide shampoo helped with a sore scalp but may cause hair root damage. Users experienced hair loss with selenium sulfide and ketoconazole, suggesting reducing use if hair loss occurs.

Mixing RU58841 with cetosomal minoxidil is discussed due to scalp irritation from ethanol PG vehicles. A mixture of the two turned bright pink when left to dry.

JW0061 shows superior hair growth results compared to existing treatments, with significant increases in hair follicles. The Wnt/β-catenin pathway is crucial for hair growth, and JW0061 activates this pathway effectively.

A user with long-term hair loss has been using topical minoxidil, finasteride, RU58841, ketoconazole, and dermastamping for 8 months. They are unsure if the new hairs are miniaturized or vellus.

The conversation is about whether to use gloves when applying 5% RU58841 to avoid systemic absorption and if washing hands with water is sufficient. Users question the concern, noting it is applied to the scalp.

A user received a custom topical treatment for hair loss from Rootsbyga, which includes minoxidil and possibly other ingredients to enhance its effectiveness. The initial test cost $120, and the monthly topical costs around $70, with concerns about long-term use of steroids like hydrocortisone.

A 24-year-old woman with AGA and TE since age 14 is questioning if her hair is regrowing or breaking. She has been using minoxidil consistently since September 2025, along with caffeine and ketoconazole shampoos, rosemary oil, and saw palmetto, and has improved her overall hair care routine.

The user is experiencing hair regrowth in small clusters using oral minoxidil, oral finasteride, a red light cap, and Nizoral 2% shampoo. They are hopeful for continued improvement and thicker hair.

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.

The user experienced tiny vellus hairs from 0.5mg finasteride and 2.5mg minoxidil over 9 months. Topical minoxidil, alfatradiol, and RU58841 applied twice daily for 1.5 months significantly improved temple hair regrowth.

A 30-year-old woman with a history of anemia and low vitamin D experienced hair shedding, which improved after addressing nutrient deficiencies. Despite regrowth of terminal hairs, her dermatologist recommended treatments like minoxidil and spironolactone to prevent future bald spots, but she is cautious due to family history of hormone-related cancers.

The user "OP" reported significant hair regrowth using oral finasteride, oral and topical minoxidil, ketoconazole shampoo, and derma stamping. OP experienced initial shedding but no other side effects.

The user has been using oral finasteride, topical minoxidil, a derma roller, and root activating shampoo for hair regrowth, seeing positive results without side effects. They apply minoxidil after using a 1.5mm derma roller and are considering switching to ketoconazole shampoo.

Increased Malassezia and Cutibacterium in the scalp microbiome are linked to higher sebum production and inflammation in androgenetic alopecia (AGA). Treatments include ciclopirox shampoo, benzoyl peroxide shampoo, clobetasol propionate, calcipotriol, minoxidil, finasteride, and dutasteride.

OP injured their temple using derma rolling and tretinoin, causing peeling and potential hair follicle damage. Users suggest the injury might be permanent, possibly resulting in scar tissue where hair won't grow.

Hair follicles are mostly dormant but can be reactivated with treatments like minoxidil, finasteride, and microneedling. A new drug, PP405, shows promise for hair regrowth but may not be available until 2027-2028.

Vitamin E and K deficiencies due to exocrine pancreatic insufficiency may affect hair growth. A scalp biopsy is recommended to check for autoimmune-related hair loss.

A study that outlines the full model for androgenic alopecia (AGA) which links DHT to cellular senescence in dermal papilla cells, and suggests black chokeberry as a source of cyanidin 3-O-arabinoside polyphenol with potential anti-oxidant properties that could reverse this process. The post encourages reaching out to experts in anti-aging and longevity to research treatments involving the polyphenol.
