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 conversation is about a user experiencing positive hair regrowth results using 1mg of dutasteride, 10% minoxidil, and occasional microneedling, after unsatisfactory results with finasteride. Other users express interest in switching to dutasteride and share similar sentiments about finasteride.

Hair is growing faster after 2 weeks of using topical vitamin D3 in alcohol/oil. The user plans to continue the experiment for 3 months before giving a full review.

Pyrilutamide is a selective AR antagonist with a high binding affinity, making it effective in competing with DHT for androgen receptors. The 1% concentration is more effective than the 0.5%, but the latter may suffice for mild hair loss; the drug is considered a good option for those avoiding 5AR blockers due to side effects.

Hair loss theory involves 3alpha-hydroxysteroid reductase (3AHD) converting DHT to androstenol. Discussion explores potential treatments and encourages more research.

The conversation is about the effectiveness of 0.25% topical finasteride compared to other concentrations and forms. Users discuss its potential for better scalp DHT reduction and fewer side effects, with some preferring topical over oral treatments.

The user started a hair loss treatment with a topical solution containing 0.1% Dutasteride, 7.5% Minoxidil, 0.0125% Tretinoin, and Biotin, along with a multivitamin, Ashwagandha, CBD oil, Retinol, and Caffeine Solution. They experienced some shedding and scalp irritation, leading to a reduction in the use of the caffeine solution.

The post discusses the completion of the HMI-115 Australian Phase 1 Trial for hair loss treatment. The user speculates about the potential early release of the trial results.

Clascoterone's full trial results are expected by mid-July 2026, but skepticism exists about timely release. Clascoterone is available at 5% from some telehealth companies.

User experienced hair growth with finasteride and minoxidil, but after using tretinoin, faced aggressive thinning and hair loss. They plan to stop tretinoin for two months to see if the problem improves.

Caffeine intake may increase DHT levels, but its impact on hair loss is minimal compared to genetic factors. Excessive caffeine can cause health issues, and its effects on hair loss are not directly applicable to humans based on rat studies.

Creatine may increase DHT levels, potentially affecting hair loss, but evidence is mostly anecdotal. A study to explore this was withdrawn due to funding issues.

Be cautious when sourcing PP405 or its analogs from third-party suppliers due to potential safety risks and lack of regulatory approval. The conversation highlights concerns about counterfeit products and the absence of reliable testing, making it risky to use such treatments.

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.

Clascoterone 5% solution shows strong potential for hair growth, offering a new treatment for alopecia with minimal side effects. It blocks androgen receptors locally and may be available by late 2026 or early 2027.

The conversation is about the approval of Clascoterone (Winlevi) in Canada for hair loss treatment. One user expressed skepticism about its effectiveness due to low concentration.

The conversation discusses interest in peptides for hair loss, specifically mentioning ahkCU and ghkCU. A user is considering adding ghkCU to their treatment regimen.

Clascoterone is promising for hair loss, showing 24.5% improvement in satisfaction compared to placebo. Users consider it an alternative to finasteride, with concerns about absorption and side effects.

A hair transplant without using finasteride or similar medications may lead to unnatural results and further hair loss. Financially capable individuals are advised to stabilize hair loss with medication before considering a transplant.

Peptides, specifically GHK-Cu, are being considered for hair growth benefits, such as increasing blood flow to the scalp and preventing hair follicle shrinkage. A user reported starting GHK-Cu after hearing it made a friend's hair thicker.

A 25-year-old male experiencing hair loss and thinning since age 20 is seeking advice on effective DHT inhibitors. He lists various oral and topical treatments, excluding Minoxidil due to adverse effects.

A new brand is seeking 10 U.S.-based individuals aged 25+ experiencing hair loss to test a topical product containing GHK-Cu and Acetyl Tetrapeptide-3. Participants must not be using other treatments like finasteride or minoxidil and will provide feedback and photos.

Follicium XR™ is a topical treatment for hair loss containing RU58841, AHK-Cu, GHK-Cu Peptide, caffeine, D-Biotin, methylene blue, keratin, and spermidine. RU58841 is considered the most effective ingredient, but concerns exist about its stability in water.

A user is considering switching from oral minoxidil to a combination of 5% topical minoxidil and tretinoin to reduce hypertrichosis. They hope this combination will be effective without causing excessive body hair growth.

A user shared their experience using topical finasteride for 6 months, showing a reduction in DHT levels but no visible improvement in hair loss. They are considering switching to oral finasteride for potentially better results.

The user shared their hair regrowth journey using treatments like dutasteride, minoxidil, microneedling, tretinoin, Nizoral, silica, biotin, and hormone replacement therapy (HRT) with cyproterone and estradiol. They reported substantial hairline improvement and some crown thinning, with hopes for further progress.

A 24-year-old male experiencing diffused thinning discusses his DHT levels and hair density issues. He has not used finasteride or dutasteride and is considering AR inhibitors.
