research (Un)targeted Scanning of Locks of Hair for Drugs of Abuse by Direct Analysis in Real Time–High-Resolution Mass Spectrometry

34 citations , January 2016 in “Analytical Chemistry”

This study reports that a new DART-HRMS method can effectively analyze intact hair for drug use timelines, with cocaine detection aligning with forensic standards and identifying multiple drugs from high-resolution data.

research Acute telogen effluvium triad after resolution

1 citations , July 2021 in “Anais Brasileiros de Dermatologia”

This study suggests that observing the acute telogen effluvium triad—frontal fringe, temporal recess, and occipital fringe—can aid in diagnosing telogen effluvium during resolution phases, despite challenges like negative pull tests.

research Segmental hair analysis - a retrospective testosterone diary?

July 2022 in “Research Square (Research Square)”

This study found that hair testosterone concentrations show some consistency over time, but factors like hair washing and individual growth rates influence these levels, suggesting the need for careful sampling and analysis adjustments.

research High-resolution single cell transcriptome analysis of zebrafish sensory hair cell regeneration

3 citations , July 2021 in “bioRxiv (Cold Spring Harbor Laboratory)”

This study used scRNA-Seq to map the transcriptional changes during zebrafish hair cell regeneration, revealing distinct phases including injury response, transient regeneration gene activation, and reactivation of developmental programs.

research Temporal Layering of Signaling Effectors Drives Chromatin Remodeling during Hair Follicle Stem Cell Lineage Progression

85 citations , January 2018 in “Cell stem cell”

This study found that synchronized signals in the microenvironment regulate stem cell lineage choices in hair follicles by influencing chromatin dynamics during regeneration.

community 35/M had transplant hair from 2019

in Transplants 411 upvotes 7 months ago

A 35-year-old man had a hair transplant in 2019 but experienced further hair loss due to not using finasteride or minoxidil. Many suggest shaving his head or considering a hair system, as his donor area is depleted and further transplants may not be viable.

community My Theory Of Androgenic Alopecia

16 upvotes 9 months ago

Hair loss is linked to cellular physiology and the IGF-1 to TGF-B1 ratio, not just androgen sensitivity. The theory lacks evidence, while finasteride and minoxidil are effective treatments.

community Hair loss research is a money grab

227 upvotes 10 months ago

Hair loss is linked to DHT, with treatments like finasteride and minoxidil being common but not definitive. Economic interests influence research, and there is potential for new treatments like PP405 and RU58841.

community Dental technician is convinced that he has found the cause of pattern hair loss

314 upvotes 2 years ago

A dental technician claims malocclusion causes pattern hair loss due to poor scalp circulation. Users debate this, noting treatments like finasteride, minoxidil, and microneedling focus on DHT and blood flow.

community The temporal peak - the often forgotten part in transplants?

in Transplants 88 upvotes 1 year ago

Temporal peaks are crucial for a natural-looking hair transplant, but they are challenging to achieve due to the need for precise angles and appropriate hair thickness. Many users emphasize the importance of finding a skilled surgeon and using finasteride to maintain hairline stability.
