This study observed unique ultrastructural changes in a 4-year-old girl with pili trianguli et canaliculi that may affect hair shaft surface characteristics due to inner root sheath alterations.

This case report highlights the importance of considering artefacts like artificial hair fibers during trichoscopy, as they can interfere with the accurate diagnosis of hair conditions.

Hair can't be as strong as Rapunzel's because it's impractical to scale up due to defects.

This study observed that donor strip scar width after hair transplantation was correlated with preoperative scalp laxity and elasticity but not with glidability.

This study found that fractional infrared technology may improve skin laxity and thickness in the cervical area without side effects in a small group of patients.

This study compiles data on the microstructural and cytotoxic properties of nano physical sunscreens, emphasizing the need for a technology platform to assess nanomaterial characteristics due to their growing use in cosmetics.

This study found that Type 3 hair oil penetrated the hair shaft more effectively than coconut oil, resulting in greater increases in hair thickness and tensile strength.

Using silicon circular iron on Korean women's hair increases hair thickness the most.

This study found that human trichohyalin has a unique protein sequence potentially contributing to at least three important functions in hair follicle and epidermal cells.

Ovariectomy in mice affects hair growth and skin thickness, suggesting potential for obesity treatment research.

In this study, 56% of patients with hypothyroidism had dry, coarse skin, while weight gain and lethargy were also common complaints.

In this study, researchers found that topical treatment with adenosine improved hair growth and thickness by significantly increasing hair density and thickness after four months in vivo, with results comparable to minoxidil, potentially due to adenosine's anti-androgenic effects.

This report describes two patients with ichthyosis linearis circumflexa exhibiting symptoms resembling Netherton's disease, noting multiple hair shaft defects and discussing a possible connection to aminoaciduria.

This study developed a multiscale model to understand human hair fiber mechanics and found that the yield stress decreases linearly with temperature, supported by both simulations and experimental stretching of hair fibers.

This study found that their novel 3D-imaging method, ASAXA-μCT, identified shrinkage of sweat glands as a key factor in skin aging, which leads to dermal defects, decreased elasticity, and increased wrinkling and sagging.

In this study, researchers found that the expression of vimentin, desmin, and laminin in rat skin contributes to cell structure and tissue integrity, with varying reactions across different cell types.

This study found that increased protein intake during fasting can nearly eliminate hair loss associated with weight loss, suggesting that protein availability is more critical than the speed of weight loss for hair growth.

In this study, a treatment combining fractional 1927nm laser with a growth factor serum was found to increase hair density and diameter in patients with androgenic alopecia over six months, without side effects, and three treatments at 4-weekly intervals were deemed most effective.

This study found that the wild-derived mouse strain Mus pahari has fragile skin that separates at subdermal levels under moderate force, potentially due to altered extracellular matrix development.

The man has a disease causing skin patches, thickened nerves, and mild muscle weakness.

This study identified a new FAK isoform, FAKΔe4, which is regulated by ECM stiffness and affects cell migration, invasion, and mechanosensing in human-derived data and engineered models.

This study reports that quantitative trichoscopy, while noninvasive and convenient, provides less accurate hair density data compared to invasive histopathologic examination, which was demonstrated in a sample of adult Chinese individuals without alopecia.

Thick scalp melanoma can be hard to diagnose because it often looks like other skin conditions.

This study documents that trichohyalin acts as a multi-functional cross-bridging protein in the inner root sheath of mouse hair follicles, enhancing mechanical strength by linking keratin filaments to the cell envelope.

This study presented 3D images of human dermis, revealing fewer elastic fibers near hair follicles compared to other regions, which may aid future skin engineering efforts.

This study suggests that age-related changes in skin elasticity reduce its stability against wrinkling, and anti-aging strategies should focus on addressing elastic mismatches between skin layers.

This article discusses the clinical features, differential diagnosis, and natural history of loose anagen syndrome in children but reports no new clinical findings.

This article discusses the issue of shock loss during hair restoration in thinning areas and reports no new clinical findings; the author shares personal insights from years of practice.

This study found that the molecular structures of α-keratin and collagen in a 2,100-year-old female cadaver's hair and tendon were preserved, while fibrous molecule aggregations were altered.

This study found that newly diagnosed breast cancer patients in Korea have different hair mineral patterns, notably reduced zinc levels, which negatively correlate with body mass index compared to normal controls.
