research A novel fracture lattice in spiny mouse skin facilitates tissue autotomy and regeneration

March 2026 in “bioRxiv (Cold Spring Harbor Laboratory)”

In this study, researchers discovered a honeycomb-like structure in the skin of spiny mice that facilitates tissue shedding and regeneration, attributed to a uniquely arranged collagen VI and influenced by spiny hair development.

research Hair Breakage in Normal and Weathered Hair: Focus on the Black Patient

37 citations , November 2007 in “The journal of investigative dermatology. Symposium proceedings/The Journal of investigative dermatology symposium proceedings”

This review discusses how hair care practices impact hair breakage, particularly in patients of color, and reports no clinical results; the authors review testing and measurement advancements and highlight gaps in understanding structural differences.

research Fast-Embeddable Grooved Microneedles by Shear Actuation for Accurate Transdermal Drug Delivery

1 citations , July 2023 in “Pharmaceutics”

In this study, researchers developed grooved microneedles made from hyaluronic acid for precise transdermal drug delivery, achieving accurate dosage with a high probability of delivery (98% or more) by using an easy-to-operate applicator for shearing force.

research New aspects of the structure of human hair on the basis of optical microscopic observations of disassembled hair parts.

1 citations , August 2015 in “PubMed”

This study discovered previously unknown structures in human hair shafts that may stabilize hair structurally and physicochemically.

research In-Situ Tensile Testing of Hair Fibers in An Environmental Scanning Electron Microscope (ESEM)

August 2007 in “Microscopy and Microanalysis”

Hair fibers break by cuticle cell slipping, shape changing, cuticle fraying, and surface cracking when stretched under specific conditions.

community Could male-pattern baldness have a secondary photobiological function? The Solar Window Hypothesis

11 upvotes 3 weeks ago

Male-pattern baldness might increase UVB exposure on the scalp, potentially affecting vitamin D and skeletal health. The hypothesis is debated, with some seeing it as a minor benefit in specific contexts.

community Hair loss research focused on chemistry for decades because we misunderstood the mechanics of growth.

51 upvotes 7 months ago

Hair growth relies on mechanical forces, not just chemicals, with tissue acting like a motor. Minoxidil and finasteride help, but maintaining tissue elasticity and addressing mechanical issues are essential.

community How to deal with mechanically induced shedding

4 upvotes 11 months ago

Minoxidil can cause scalp dryness and flaking, leading to hair shedding when exfoliating. Alternatives like oral Minoxidil, finasteride, and ketoconazole shampoo are suggested to manage these issues.

community Funny Encounter With a Mechanic - Hair Loss Update

in Update 39 upvotes 5 months ago

The user has been taking 3.75mg of finasteride weekly for 8 months, which has improved their hairline and hair texture. They shared a humorous encounter with a bald mechanic who complimented their hair, unaware of the finasteride use.

community Hi-c5 protein, explains why the mechanical tension theory may be correct.

22 upvotes 4 weeks ago

Hair loss may be influenced by mechanical tension and inflammation, with the hi-c5 protein amplifying androgen effects, leading to follicle miniaturization. Treatments like finasteride, minoxidil, and scalp massages are suggested to manage hair loss.
