research Single hair analysis by X-ray fluorescence spectrometry detects small changes in dietary zinc intake: A nested randomized controlled trial

11 citations , March 2023 in “Frontiers in Nutrition”

This study found that a modest increase in dietary zinc over six months resulted in a detectable increase in sulfur and zinc counts in individual hairs, suggesting a non-invasive method to monitor zinc intake effects.

research Ocfentanil testing in hair from a fatality case: Comparative analysis of a lock of hair versus a single hair fiber

1 citations , July 2021 in “Forensic science international”

This study found that segmental single hair analysis produced ocfentanil concentration profiles similar to those from hair lock analysis, supporting its use in cases with limited samples.

research Single cell analysis of transcriptome and open chromatin reveals the dynamics of hair follicle stem cell aging

3 citations , July 2023 in “Frontiers in Aging”

This research detailed a single-cell atlas showing dynamic hair follicle stem cell states associated with the hair cycle during aging in mice, highlighting differences in chromatin landscape linked to stem cell differentiation and quiescence, and providing a foundation for future exploration of aging reversal.

research Single‐Cell Analysis of Late‐Stage Wound‐Induced Hair Follicle Neogenesis Reveals Keratinocyte Heterogeneity and Enrichment of Infundibular Basal Keratinocytes

June 2026 in “Experimental Dermatology”

This study used single-cell RNA sequencing to explore the cellular differences between small and large wound tissues during the hair follicle regeneration stage, revealing variations in keratinocyte subpopulations and extracellular matrix interactions associated with wound size.

Analysis of Gene Expression in Isolated Single Hair Follicles Using Semiquantitative Reverse-Transcriptase Polymerase Chain Reaction

research Analysis of Gene Expression in Isolated Single Hair Follicles: An Approach Using Semiquantitative Reverse-Transcriptase—Polymerase Chain Reaction

May 1995 in “Journal of Investigative Dermatology”

Researchers developed a new way to measure gene activity in single hair follicles and found that a specific gene's activity changes with different amounts and times of treatment.

community Meta analysis of minoxidil only vs 5AR inhibitors

in Research/Science 58 upvotes 1 year ago

Oral dutasteride is the most effective for hair regrowth, followed by oral finasteride and minoxidil. Topical finasteride combined with minoxidil is recommended for those avoiding systemic DHT reduction.

community Shaved it off a couple weeks ago. One of the best things I've ever done [PHOTOS/ANALYSIS]

6 upvotes 12 years ago

The user shaved their head and noticed some hair regrowth and thickening due to Minoxidil and finasteride. They are content with their hair loss and have accepted it, while also observing that others don't notice the thinning as much as they do.

community Hair disappearing after one week (microscope photos)

747 upvotes 1 year ago

A user is concerned about hair loss despite using finasteride and minoxidil, noting changes in hair under a microscope after one week. Others suggest patience, as hair treatments take months to show results, and recommend focusing less on microscopic changes.

community We already know how to permanently fix hair loss. The science is done. The only thing missing is the funding to run one experiment.

in Technology 613 upvotes 4 months ago

A permanent hair loss solution could involve reprogramming hair follicles to resist DHT using mRNA and siRNA. However, high costs, safety concerns, and the pharmaceutical industry's preference for ongoing treatments over one-time cures are major obstacles, with finasteride and minoxidil remaining standard treatments.

community End of Hair loss ( AGA ) ? Since they produce it in china probably we don’t need to wait other 10 yrs😁

276 upvotes 6 months ago

GT20029 is a new hair loss treatment in Phase 3 trials in China, using PROTAC technology to target androgen receptors, potentially with fewer side effects than finasteride and minoxidil. VDPHL01, a second-generation minoxidil, is also mentioned as potentially more effective.
