The discussion revolves around whether the hair loss is due to male pattern baldness, alopecia areata, or a vitamin deficiency.

The conversation discusses concerns about the potential risk of cancer from creating new hair follicles through microneedling, due to stem cell division. Specific treatments mentioned include microneedling, caffeine-containing anti-hair loss shampoos, and other unspecified topicals.

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.

Topical melatonin may help reduce hair loss and increase hair thickness in people with androgenetic alopecia (AGA), with some studies showing positive results. It can be mixed with minoxidil for application, and its effectiveness might be enhanced when used with micro-needling, but results may vary among individuals.

They reported slight hair regrowth after one month and plan to continue the regimen, noting improvements in skin sensitivity and managing dandruff with anti-dandruff shampoo.

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.

A 19-year-old has been using finasteride, minoxidil, and microneedling to treat hair loss with no regrowth, feeling mentally affected by it. Advice given includes continuing treatment, considering a hair transplant, addressing potential vitamin deficiencies, and possibly switching to dutasteride or adding ketoconazole shampoo.
