This case report detailed a successful treatment involving contracture release and expanded neck flap reconstruction for a patient with severe neck contracture and beard alopecia from past thermal burns, highlighting improved skin quality and hair regrowth following follicular unit extraction.

In this study, researchers observed that telogen hair was more prevalent than anagen hair in both male and female agoutis over a one-year period in Teresina-PI, regardless of dry or rainy seasons, with no significant differences in dermal follicular volume between the sexes.

In this study, the immunohistochemical and lectin binding profiles of basal cell carcinoma closely resembled those of the outer root sheath of vellus hair follicles, suggesting a potential histochemical relationship.

In this study, researchers found that bulge cells in mouse hair follicles undergo transient proliferation during early anagen, indicating their role as follicular stem cells. However, another factor beyond dermal papilla proximity may be required to initiate a new anagen phase.

This study examined the follicular unit density in the scalp and beard donor areas of Indian men undergoing hair restoration surgery, reporting mean densities of 78.2/cm² and 49.7/cm² respectively, and proposed guidelines for safe follicular unit extraction.

Early diagnosis and treatment can help manage fibrosing alopecia in older women.

This study suggests that follicular stem cells in the bulge region are not directly targeted in androgenetic alopecia, based on the consistent presence of cytokeratin 15 across scalp samples from affected patients.

In this study, researchers found that hair follicle stem cells in mice can generate both hair follicle and epidermis cells, highlighting their potential bipotency.

In this case report, a 44-year-old woman underwent a successful hair transplantation using follicular unit extraction on a myocutaneous free flap, resulting in an 80 to 85% hair survival rate after 12 months and significant improvement in external alopecia aesthetics.

This study describes the anatomy of arrector pili muscles in scalp hair follicular units, proposing a model where a single muscle structure is shared by all follicles within a unit.

This study found that hair diameter varies significantly within the occipital safe donor area, with thicker hair in the upper sections and thinner hair in the lower sections.

Congenital triangular alopecia can occur outside the typical fronto-temporal region.

This study found that disrupting Stat3 in keratinocyte stem cells of mice reduced skin tumor formation by approximately 80%, suggesting Stat3's role in tumor initiation survival mechanisms.

This study identified specific markers that can distinguish between stem cells in different regions of human scalp hair follicles, offering potential strategies for cell sorting and purification based on these markers.

This case report describes an increase in crown hair coverage using body hair transplantation from the chest and suprapubic regions, suggesting these as viable donor sites but emphasizing the need for standardized patient selection and follow-up.

The authors concluded that Lrig1-positive stem cells are essential for sebaceous gland formation in mice, as their ablation led to temporary sebaceous gland disappearance without affecting hair growth.

The study found that balding scalps have more thin hairs and larger oil glands, which might contribute to skin conditions related to hair loss.

This study reports that the near-naked hairless mutation in mice is not an allele of the Hairless gene but may involve a mutation in a linked gene or a regulatory mutation.

This study concluded that a liquid serum formulation delivered two fluorescent dyes to deeper follicular regions more effectively than nanoparticle systems.

This review discusses recent advancements in understanding hair follicles, their disorders, and potential therapeutic opportunities, but it reports no new clinical findings.

This case report describes a 54-year-old man diagnosed with fibrosing alopecia in a pattern distribution, presenting with follicular inflammatory lesions and scleroatrophy on the scalp.

In this study, researchers found all donor sites except the neck region suitable for midfrontal hairline restoration in Southeast Asian women, with donor site hair density and diameter tending to decline with age.

In this study, a single application of autologous cellular micrografts showed short-term favorable responses in up to two-thirds of patients with androgenetic alopecia.

This study examined 15 female patients with hypothyroidism to investigate the characterization of their alopecia and ruled out other causes, using medical histories, and clinical, trichoscopic, and histologic findings.

This article discusses how facial plastic surgeons can incorporate hair restoration into their practices and reports no new clinical results.

This study captured digital images of hair regions in healthy individuals and patients with androgenetic alopecia to analyze and compare the number of follicular units and hairs using software.

This review discusses the surgical methods of hair restoration, highlighting the density benefits of scalp reduction and rotation, but reports no new clinical findings.

This study reported that a new PRP application protocol with two treatments enhanced hair growth metrics in the vertex region of androgenetic alopecia patients within six months.

This study found that in scarring alopecia, stem cells are differentially localized, suggesting that both inner and outer root sheath stem cells, rather than just follicular bulge stem cells, are involved.

This workshop overview concluded that follicular epithelial stem cells are multipotent and located in the bulge region of hair follicles, contributing to hair, epidermis, and sebaceous gland formation.
