In this study, alopecia areata patients treated with diphencyprone showed a significant increase in CD8 lymphocytes around hair bulbs, which may be associated with hair regrowth.

This study on Dorper sheep identified important genetic factors influencing hair follicle development, finding that expression patterns and genes like DBI, FZD3, and ZDHHC21 play a crucial role in wool shedding, which could help improve understanding of mammalian skin-related traits and human hair advancement.

Two siblings have a rare genetic condition causing curly, coarse hair.

In this study, cryopreserved mouse whisker hair follicles were shown to maintain their hair growth potential and functional recovery, with DMSO being more effective than glycerol for cryopreservation.

This study developed a dissolvable microneedle system delivering specific molecules to remodel lymphatic networks and normalize metabolic processes, which accelerated hair growth and activated hair follicle stem cells in a mouse model of androgenetic alopecia.

This study found that spermidine, a polyamine, plays an essential role in hair growth in sheep follicles, while spermine is not required for normal follicle function.

This study reported that the coat hairs of golden takin, living in harsh environments, have unique structural features compared to cattle, with overcoat hairs having continuous medullated tissue and undercoat hairs being finely crimped, potentially contributing to temperature regulation in cold conditions.

In this case report, a 23-year-old woman developed localized trichorrhexis nodosa after compulsively applying 3% minoxidil to her scalp for two months.

This report highlights a case where dermoscopic observation of corkscrew hairs in a young woman led to the diagnosis of trichotillomania, emphasizing its role in distinguishing this psychiatric disorder from other forms of non-scarring alopecia and highlighting the importance of timely intervention.

The Dfl mutation in mice causes poor sebaceous gland function and complete hair loss.

In this study, the authors identified a role for hair follicles in regulating the formation and sympathetic innervation of arrector pili muscles, influencing hair follicle stem cell activity and potentially explaining hair loss associated with beta-blockers and androgenic alopecia.

Deoxyshikonin from Arnebiae Radix helps hair grow by activating a specific cell pathway.

This review discusses the natural habitat, taxonomy, phytochemical components, pharmacological activities, and potential medical applications of Tridax procumbens but reports no new experimental findings.

This study suggests that Ecklonia cava, particularly its component dioxinodehydroeckol, may promote hair growth by enhancing dermal papilla and outer root sheath cell activity in culture and mice models.

In this case report, a 22-year-old female was diagnosed with follicular Dowling-Degos disease based on clinical and histological findings, with symptoms including skin lesions confined to hair follicles. The report emphasizes the importance of differentiating this rare variant from similar conditions for proper management.

This study observed that mice with a Cx43 mutation exhibited slower and asynchronous hair regrowth with severe cuticle weathering, mimicking aspects of hair phenotype in some ODDD patients.

This abstract suggests that specific trichoscopic features like black dots, coiled hair, and trichoptilosis may help differentiate trichotillomania from patchy alopecia areata.

This study found that in Vdr-knockout mice, hair follicles fail to complete the catagen stage, leading to persistent epithelial strands and subsequent hair loss.

In this study, DOP treatment improved hair regrowth in androgenetic alopecia by altering local steroid metabolism and follicular morphology.

In this case study, a 15-year-old obese boy was diagnosed with acanthosis nigricans and hair casts in the axillae, with Wood's lamp and dermoscopic examination revealing specific features, yet fungal infection was ruled out through a negative KOH test.

This study proposes a model describing the transformation process from living to dead cells during early hair formation, highlighting the stepwise degradation of cellular functions.

Allergic contact dermatitis may promote hair growth by activating hair follicle stem cells.

In this study, Avemor, a tonic containing aloe vera and moringa oleifera, along with varying concentrations of dried moringa leaf extracts, was tested on rabbits for hair growth, but the results showed variable effectiveness compared to a minoxidil control.

This study suggests that diffuse alopecia areata initially involves an intense inflammatory attack during the anagen phase, progressing through different hair cycle stages with specific shedding patterns.

This study found that a cream containing 6.0% Stryphnodendron adstringens bark extract effectively reduced terminal hair growth and improved skin conditions in women with excessive terminal hair.

This article discusses the familiarity of identifying male androgenetic alopecia but presents no new research findings.

This study found that a patient with giant axonal degeneration had unique hair abnormalities such as trichorrhexis nodosa and altered S:N ratios, unlike her relatives but comparable to unrelated controls.
