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.

Fatty acid metabolic signaling can activate epithelial stem cells for hair regeneration. Oleic and palmitoleic acids showed the best results, but practical application on humans remains uncertain.

The conversation is about the best microneedling depth and frequency for hair loss treatment. The user recommends 1.5mm once a week.

The post discusses the confusion about the optimal microneedling depth and frequency for hair growth, and when to apply treatments like minoxidil. A reply suggests the best method is using a 1.25mm depth every 7 days with a specific device, holding it for 10 seconds to stimulate hair growth.

Keratin microspheres may offer additional mechanisms to combat hair loss compared to minoxidil. The process to create these microspheres is relatively simple and can be done at home with basic equipment.

The conversation is about hair regrowth using high-dose dutasteride, oral minoxidil, and microneedling. Users discuss seeing tiny hairs and hope they will become terminal, with advice to use derma rolling weekly for better results.

The conversation discusses experiences with topical dutasteride for hair loss, comparing formulations from FUEClinic, MinoxidilMax, and Strut. Users share their results and side effects, with some preferring topical over oral treatments to minimize systemic absorption.

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.

Scalp biopsies are crucial for diagnosing hair loss conditions like Diffuse Unpatterned Alopecia (DUPA) and retrograde hair loss, as treatments like finasteride and dutasteride may not be effective if other conditions are present. Combining PPAR-GAMMA agonists with retinoids could improve treatments for conditions like Lichen Planopilaris.

Lichen Planopilaris (LPP) is an autoimmune condition causing permanent hair loss and fibrosis, often misdiagnosed. Treatments include pioglitazone, topical corticosteroids, anti-inflammatory medication, and Jak inhibitors.

The conversation humorously outlines the progression of hair loss and the increasing desperation for treatments, starting with vitamins and dermapen, moving to finasteride, then to dutasteride and experimental chemicals, and finally to acceptance with shaving or hoping for hair cloning. Some users agree with the accuracy, while others question if it's a joke.

The conversation discusses applying a topical solution containing 0.01% tretinoin, 1.5% azelaic acid, and 5% minoxidil for hair loss. It is recommended to apply tretinoin at night and use sunscreen during the day to prevent skin damage.

The conversation discusses how different factors can stimulate type 1 and type 2 isoforms of 5-alpha reductase, which are enzymes linked to hair loss. Specific treatments mentioned include oral Dutasteride and topical Finasteride.

Minoxidil is unlikely to cause skin aging at typical doses, and concerns about collagen inhibition are mostly unfounded. Users suggest using sunscreen and tretinoin for skin health, and some combine minoxidil with finasteride for hair maintenance.

The conversation discusses concerns that Minoxidil may cause skin aging, like collagen depletion and puffier faces. Some users suggest that a good skincare routine or collagen supplements might prevent these effects.

Microneedling depth should be customized based on hair type and scalp area, with many users finding 0.5-0.6mm effective for miniaturized hairs to avoid damage. Users report varying pain levels and results, with some preferring shorter needle lengths and others using longer ones like 1.75mm for scalp health and density improvement.

A user shares a routine using Nizoral 2% shampoo twice a week, followed by Ego QV Nourishing Shampoo and Conditioner, and Schwarzkopf Extra Care Hair Treatment Oil to prevent dryness and maintain healthy hair texture. Others discuss similar experiences with ketoconazole, noting improvements in dryness and reduced hair shedding.

User shares progress after 4 months of using finasteride and dermarolling, with occasional use of coconut and rosemary oil. They aim to stop hair loss and hope for increased top density.

The discussion is about using ASCEplus HRLB exosomes for hair loss treatment, which combines 10 billion exosomes with growth factors, nutrients, biotin, and copper tripeptide. The treatment is expensive and typically administered via scalp injections, but in Europe, it's done with microneedling.

A 36-year-old is experiencing underwhelming results from derma stamping for hair thinning, using needle lengths of 0.5mm to 0.75mm. They are considering increasing needle length, taking a break, or pairing the treatment with rosemary oil.

Hair loss discussion includes treatments like hinoki tree oil and procyanidin b2. Experiences and effectiveness of these treatments are shared.

The conversation discusses a hair loss treatment regimen that includes a topical spray with finasteride and minoxidil, tretinoin, and using a Derminator (microneedling device) at 1.25mm depth every 5-6 days. The user reports positive results after 90 days and plans to continue the treatment, with others commenting on the process and potential outcomes.

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.

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.

Hair follicles can be dormant and potentially revived with treatments like finasteride and minoxidil, but irreversible loss occurs if certain structures are destroyed. Early intervention is more effective, and additional methods like microneedling may help.

Microneedling at depths greater than 0.6 mm may damage miniaturized hair follicles, with 0.5 mm showing better results for hair regrowth. Combining microneedling with minoxidil enhances absorption, but caution is advised to avoid damaging follicles.

The conversation discusses the difficulty of applying tretinoin 0.025% cream on the scalp and considers switching to a gel for easier application. It also mentions that a liquid solution, ideally combined with minoxidil, may be more effective for hair treatment.

Hair regrowth can start as thin hairs that may thicken over time, with treatments like finasteride and minoxidil showing varied results. Some users report initial shedding followed by thicker regrowth, while others experience mixed outcomes in different areas.

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.

A user plans to experiment with creating new hair follicles using methods like derma rolling, applying lithium chloride, tannic acid, and various other substances including caffeine, ketoconazole, and raspberry ketones. They also consider using anti-inflammatories, immunosuppressants, and DHT inhibitors to potentially improve results.
