An 18-year-old noticed hair thinning at 17, started finasteride 5 months ago, and saw shedding stop but no regrowth. They suspect male pattern baldness due to family history and are concerned about thinning on the back and sides, possibly due to inflammation.

A 22-year-old male uses dutasteride, a serum with 10% minoxidil and 0.5% finasteride, and microneedling for diffuse androgenetic alopecia. Progress pictures show changes from July 2025 to February 2026.

The conversation discusses a new model for understanding androgenetic alopecia (AGA), linking it to dietary and lifestyle factors similar to PCOS, and highlighting the role of DHT, vascular damage, and inflammation. Treatments mentioned include Minoxidil, finasteride, and RU58841.

The conversation discusses using a combination of finasteride, spironolactone, minoxidil, retinol, azelaic acid, and caffeine for hair loss treatment. The user inquires about the limitations of these drugs and whether tretinoin would be more effective than retinol.

A 25-year-old male experiencing diffuse thinning is advised to address high TSH levels and low iron, and consider treatments like finasteride. Weight loss and improved diet are also suggested to potentially help with hair health.

The user checked iron, ferritin, B12, zinc, testosterone, DHT, and estrogens to understand hair loss causes and the effects of dutasteride. They also noted increased heart rate and paleness with oral minoxidil.

A user shared their journey of improving their overall appearance and health after starting to lose hair at 21, which led them to adopt a healthier lifestyle, including better dental hygiene, dieting, and exercise. They used biotin, Rogaine, and finasteride to combat hair loss and emphasized self-improvement despite the possibility of still losing hair.

A 20-year-old male experienced bald spots and used minoxidil, which led to hair regrowth but also premature graying. He seeks advice on reversing graying through diet or supplements like catalase, while another user suggests vitamin D3 and sesame for hair color.

DHT may inhibit hair growth by affecting mitochondrial function, leading to hair follicle miniaturization. Treatments like minoxidil and PP405 may promote hair growth by altering metabolic pathways, potentially counteracting DHT's effects.

HMI-115, a potential treatment for hair loss that can reverse miniaturization and make individual hairs thicker, as evidenced by data from macaques given the treatment and one subject in the phase I trial.

Procyanidin B2, a compound derived from Annurca apples, as a potential treatment for pattern hair loss. Several clinical studies were mentioned, which found that procyanidin B2 could increase hair growth, density, and keratin content. Other treatments such as Minoxidil, Finasteride, and RU58841 were not discussed.

The post discusses using ImageJ software to objectively track hair regrowth progress. The user is treating Androgen alopecia with dutasteride and minoxidil.

The user is experiencing hair loss, initially diagnosed as Telogen Effluvium due to stress, but is concerned it might be Androgenetic Alopecia (AGA). A suggestion was made to consider using Minoxidil or Finasteride if the condition worsens.

RU58841 may still be potent after being left unopened for four months if protected from light and air. A user reported hair improvement using RU58841 with minoxidil, without major shedding, over 2.5 years.

The conversation discusses the lack of in vivo studies on the effects of minoxidil and finasteride on human collagen and elastin after a year of use. It highlights the potential benefits of such research for understanding side effects and improving sales, despite challenges like cost and competition.

A 26-year-old male experienced significant hair regrowth using a 4-in-1 topical treatment from Hims, which includes minoxidil, finasteride, ketoconazole, and biotin, over four months. The user reported increased body and beard hair, skin changes, and no negative sexual side effects, while others noted the rapid and impressive results as atypical.

The conversation discusses hair regrowth using Scandinavian Biolabs products, biotin pills, a dermaroller, rosemary oil, and a silicone head cleaner. The user observes weak hair regrowth and seeks opinions on the results.

A user is frustrated about early balding despite older male relatives retaining hair into old age. Another user plans to start finasteride soon to address their hair thinning.

The user successfully regrew thick hair using minoxidil, finasteride, and biotin, starting at age 19, and expresses gratitude to the community for support. They experienced minimal side effects and emphasize the importance of personal research and a healthy lifestyle.

Hair loss treatments like minoxidil, finasteride, dutasteride, and RU58841. Users stress early prevention and discuss challenges with different hair loss patterns.

A 28-year-old shared surprising hair regrowth progress after 20 days using topical minoxidil, micro needling, GHK-cu, and BPC-157 injections. The user noted a significant reduction in their bald spot and overall hair improvement.

User shared 3.5 months of hair regrowth progress using oral minoxidil 2.5 mg and microneedling, noting a younger appearance. Replies included congratulations and comments on the impressive results.

The user "ajsr8" shared their story of hair loss despite being on treatments. They started using finasteride in 2019 and later tried topical minoxidil, but it didn't seem to work. They also experienced side effects from other treatments. They are considering cutting off their hair and stopping the medications if there is no improvement in three months. Other users suggested trying different treatments and getting a blood test to check for underlying conditions.

Researchers finding that microRNA can potentially regrow 90% of lost hair, and the challenges involved in moving this research forward to human trials. Various treatments for hair loss, such as finasteride and minoxidil, have been discussed.

Probiotics like L. reuteri ATCC PTA 6475 and B. longum BB536 may improve hair growth and density by reducing inflammation and reversing DHT damage. The user is trialing these probiotics personally, ordering them from the U.S. to Canada, and plans to continue if no adverse effects occur.

Feeding bacteria-free mice with Lactobacillus murinus worsened hair loss, but a regular diet with biotin stopped it. The conversation suggests gut bacteria and diet may influence hair loss, with some skepticism and discussion about other factors like DHT and genetics.

The user experiencing diffuse hair loss is using various treatments including RU58841, finasteride, minoxidil with tretinoin, anti-hair loss shampoo, and microneedling, and is considering adding peptides TB500, BPC157, and GHK-Cu.
