This study found that age-related changes in scalp dermal fibroblasts, including increased MMP-1 and reduced ECM components, may significantly affect the hair follicle environment and contribute to hair aging.

This study found that wound healing after scald burns in mice was slower in deeper burns, but the healing quality in second-degree deep scalds was similar to normal healing.

This study found that phosphorylated VEGFR-2 is present in human scalp epidermal appendages and suggests it plays a role in their daily regulation.

In this study, researchers found that as androgenetic alopecia severity increased, the hair follicle matrix and dermal papilla's volume and cell nuclei number decreased, especially in the papilla.

This review synthesizes evidence on strategies to preserve donor aesthetics and reserve in follicular unit extraction, emphasizing conservative extraction limits and long-term planning to prevent donor site morbidity.

This study validated the Black Identity, Hair Product Use, and Breast Cancer Scale (BHBS) as a tool to measure social and cultural factors related to hair product use and perceived breast cancer risk in Black women.

This study developed an efficient method for converting polymeric procyanidins into high-purity oligomeric procyanidins using a semisynthetic approach combined with separation techniques.

In this review, researchers examined the molecular diversity and expression patterns of major skin appendage proteins, like keratins and EDC proteins, in tetrapods, highlighting recent findings in reptiles and birds and identifying knowledge gaps for future research.

This study found that hair from ovarian teratomas shares similar chemical composition and morphology with scalp hair, but differs in physical properties and cysteic acid bands.

This study observed that amelanotic melanocytes from human hair follicles appeared morphologically immature, suggesting they might not transfer melanosomes into keratinocytes.

Hair grows from living roots, is made of dead keratin, and goes through growth, rest, and shedding stages.

This review covers hair anatomy, common hair diseases, diagnostic approaches, management, and hair care, but reports no new clinical findings; the authors highlight the importance of proper hair care knowledge.

This study found that using serum-free Williams E medium was more effective for culturing human scalp hair follicles in vitro, suggesting it may improve hair follicle regeneration between hair transplant procedures.

This article discusses hair care practices and hair cosmetics in managing alopecia but reports no new clinical findings; it emphasizes the importance of scalp health and good patient-physician communication.

This study identified the expression sites of five KAP5 genes on human chromosome 11q13.5 in scalp skin sections but did not explore their detailed distribution within hair follicles.

This study utilized UK Biobank data to identify genetic factors associated with self-perceived facial aging, highlighting significant roles for skin pigmentation, immune pathways, and extracellular matrix genes.

This study found that intense pulsed light treatment primarily targets pigmented structures in hair follicles and may damage dermal papilla cells at high energy levels, but stem cells are mostly spared.

This article reviews literature on hair casts, shedding light on this rarely discussed hair disorder, along with a case report of a 5-year-old mistakenly treated for head lice.

This article reviews the roles and synthesis of essential long-chain fatty acids in the body and reports no new research findings; it emphasizes the importance of dietary sources for these lipids.

This article reviews historical reports of skin changes, such as pseudoacanthosis nigricans, associated with cholesterol-lowering drugs like triparanol and nicotinic acid, but presents no new clinical findings.

This paper reviews the literature on acquired trichorrhexis nodosa, a clinical hair loss diagnosis associated with hair care practices, particularly in those with tightly curled hair, and emphasizes management through protective hair care regimens rather than traditional prescription therapies.

This review discusses the use of trichoscopy as a valuable diagnostic and prognostic tool for various hair and scalp disorders, reporting no new clinical results.

Reflectance confocal microscopy helped diagnose and manage a woman's hair loss without needing a biopsy.

This study reports that scalp biopsies in white adults usually have 16.5 hair follicles, primarily in the anagen phase, with male samples showing fewer follicular units but more fibrous tracts in certain areas.

This research examined the ultrastructure of deer hair fibers and found significant variations in diameter, cuticle thickness, and intermediate filament arrangements among different fiber types.

This article reviews structured management strategies for diagnosing and treating hair and scalp disorders, offering clinical guidelines and emphasizing the importance of psychosomatic care and patient-therapist communication.

This case report details a 28-year-old male with early-stage androgenetic alopecia who experienced significant hair density and thickness improvements following a three-month platelet-rich plasma therapy regimen, supporting its potential efficacy in similar cases.

In this case report, a 28-year-old male with androgenetic alopecia experienced significant improvement in hair density and shaft thickness after a three-month platelet-rich plasma therapy regimen, supporting existing literature on PRP's efficacy for early-to-moderate hair loss.

This study utilized U-Net's image-processing capabilities to achieve 92% accuracy in segmenting individual hair strands, enhancing early detection and reliable identification of hair fall areas, which assists in addressing challenges of subtle hair thinning that are difficult to see otherwise.

This review discusses the impact of chemotherapy-induced alopecia on cancer patients, the current use of scalp cooling for prevention, and potential future treatments, but presents no new clinical results.
