A new hair loss treatment, PP405, showed promising Phase 2a results with 31% of patients experiencing over 20% hair density increase without systemic absorption, avoiding hormonal side effects. The treatment is expected to be expensive, with Phase 3 trials starting mid-2026, and there is skepticism about the data's strength.

A 28-year-old male is using Minoxidil 5% with tretinoin and azelaic acid for hair loss and is considering finasteride but is concerned about side effects. He seeks advice on recovering his temple area.

The user has been using finasteride for over two years with mixed results and is considering starting dutasteride and oral minoxidil, though both are hard to obtain. They are also contemplating a hair transplant in the future due to diffuse thinning.

A 19-year-old male experiencing diffuse hair thinning has been using oral minoxidil and finasteride for 6 months with no improvement. Suggestions include continuing the treatment, checking for underlying conditions, and considering nutritional or hormonal causes.

Adding tretinoin to a minoxidil routine can cause initial hair shedding, which may be normal as it potentially increases minoxidil's efficacy. Users suggest being cautious with tretinoin application, especially around microneedling, to avoid increased systemic absorption.

Tretinoin can cause non-telogen hair loss in some men by inducing catagen-like changes in hair follicles and through retinoid toxicity, especially when used with minoxidil. Some users report hair loss even when using retinoids on the face, while others experience benefits when combined with treatments like finasteride and minoxidil.

Microneedling promotes hair growth by increasing circulation and collagen production, with gains potentially lasting longer than those from minoxidil. Some users report sustained results after stopping microneedling, unlike with minoxidil and finasteride.

A 23-year-old experiencing severe diffuse thinning after scalp inflammation is considering finasteride as a last resort after stopping minoxidil and using anti-inflammatory medication. Users suggest that inflammation causes temporary shedding and recommend consulting a dermatologist, with some advocating for finasteride as a reliable treatment option.

A breakthrough in hair follicle cultivation using induced pluripotent stem cells (iPSCs) has been achieved, producing large hair follicles suitable for transplantation. Clinical trials for this hair multiplication technology are planned in partnership with Yinguan Biotechnology.

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

A 29-year-old is using oral minoxidil, finasteride, hormone replacement therapy (HRT), and microneedling for hair regrowth. They started balding at 20, worsened at 25, and are transitioning with testosterone blockers.

A 20-year-old male has been using oral minoxidil for hair thinning but is considering adding finasteride due to recent thinning and DHT effects. He plans to consult a dermatologist for finasteride to maintain or regrow hair.

Liver problems may reduce the effectiveness of oral minoxidil due to impaired SULT1A1 enzyme activity, which is crucial for converting minoxidil to its active form. This reduction in enzyme function can significantly decrease the drug's effectiveness in promoting hair growth.

GT20029 is anticipated to start phase III trials in Q3 2026, with potential public availability around 2029-2030.

The conversation discusses the potential benefits of sublingual minoxidil for hair loss treatment. It suggests that sublingual minoxidil, which bypasses the liver, may have fewer side effects, greater bioavailability, and could be more effective than oral minoxidil.

Ultrasound imaging can non-invasively detect active and inactive hair follicles, inflammation, and fibrosis, potentially reducing unnecessary biopsies. It may help assess hair growth potential and diagnose scalp issues, but some users believe in trying treatments regardless of ultrasound results.
