This chapter provides an overview of the complex chemical and physical structure of the hair surface, detailing how factors like ethnicity, environmental stress, and cosmetic treatments can alter its properties and influence the adhesion of hair care products.

This study found that fibronectin nanofiber dressings, made using rotary jet spinning, accelerated wound healing and improved tissue restoration in a full-thickness wound mouse model.

This study introduced a new high-throughput method for analyzing scalp hair morphology and found that quantifying hair form provides more accurate information than traditional classification based on racial categories, challenging the belief that cross-sectional morphology predicts hair curvature.

This study found that micro-computed tomography (micro-CT) was highly effective for analyzing the cross-sectional geometry of hair fibres, including the medulla in highly curled hair, but less effective than scanning electron microscopy for surface details.

This study introduces the PRECISE scale, a quantitative tool to classify androgenetic alopecia, aiming to improve planning and outcomes for hair transplantation surgeries by evaluating the whole hairless and thinning areas.

This article discusses the development of a standardized assessment scale for hair transplant outcomes, emphasizing multiple parameters that contribute to an aesthetically pleasing result and reports no new clinical findings.

This article presents a comprehensive guide for classifying human hair follicle cycle stages in vivo using scalp xenografts on immunocompromised mice, offering valuable resources for researchers in the field.

This study reported that finasteride 1 mg/day significantly increased hair growth and slowed hair loss in men with frontal scalp hair thinning over one year, and these benefits continued or improved in the second year.

In this study, a new shading model for hair was developed that better matches real-life light scattering, thanks to detailed new measurements of hair fiber scattering not predicted by existing models.

This study introduced a new hair shading model that more accurately simulates light scattering on hair fibers, capturing effects not predicted by previous models.

Mutations in the DSG4 gene cause specific hair and scalp issues.

This study found that eosinophils are a useful diagnostic feature for alopecia areata, especially when the typical "swarm of bees" lymphoid infiltrate is absent, helping differentiate it from trichotillomania.

This study reported that chemical relaxants and hair styling practices were associated with scarring hair loss, particularly among women with central centrifugal cicatricial alopecias.

This study identified two types of calcium in human scalp hair, with one type highly variable between individuals, potentially impacting the analysis of environmental and medical factors related to hair calcium.

This article reviews recent advancements in hair transplantation techniques, particularly follicular unit transplantation, and suggests an expansion of its applications beyond male pattern hair loss, but reports no new results.

This review highlights that transferosomes, or ultradeformable lipids, show promise for improving dermal delivery, exhibiting efficient drug transport across the skin's barrier and offering potential benefits for treating chronic skin disorders with better bioavailability.

This review discusses lichen planopilaris in children and highlights its rarity, potential for misdiagnosis, and need for suspicion in atypical or treatment-resistant alopecia cases, but reports no new results.

This review reports on the principles, applications, and future potential of bioprinting technology in fields like tissue engineering and organ regeneration, highlighting recent advancements and identifying ongoing challenges and future directions that require collaborative efforts to fully realize the technology's capabilities.

This review examines the role of follicular unit transplantation in restoring eyebrow fullness and architecture but does not present new experimental findings, emphasizing the importance of technique for achieving natural results.

This review discusses various follicular unit excision methods, punch designs, and motorized devices, highlighting their roles in reducing hair follicle transection rates and optimizing graft harvesting for individual patient characteristics.

This study found that scanning electron microscopy can identify four specific hair morphology patterns in alopecia areata patients, offering a less invasive diagnostic option compared to punch biopsy.

This study explored the molecular biology of skin adaptations in pangolins, revealing that certain genes for lipid synthesis have inactive patterns, while others related to skin function remain intact, suggesting complex evolutionary changes in their skin physiology.

The cephalic approach for nerve blocks is less painful than the anterior approach during hair restoration surgery.

In this case report, researchers observed that a malnourished male patient developed pseudoglucagonoma syndrome, characterized by necrolytic migratory erythema and diffuse hair loss, following Frey's surgery, which rapidly improved with enhanced nutrition.

In this in-vitro study on human hair follicle cultures, researchers reported that the HAIR & SCALP COMPLEX significantly enhanced hair bulb growth and dermal papilla regeneration compared to other treatments, suggesting a potential new approach for managing hair loss and promoting growth.

This abstract describes a rare case of a young Kashmiri woman with neglected scarring alopecia due to favus, a type of tinea capitis more commonly observed in Kashmiri children.

A 5-year-old girl with a rare skin disorder was effectively treated with skin creams instead of oral medication.

The document lists various dermatology topics, treatments, and diagnostic methods.

Lichen planopilaris is a rare, chronic condition causing hair loss, mainly in middle-aged women, and early treatment is important to prevent permanent baldness.

This study found that encapsulating latanoprost in nanotransfersomes increased skin penetration and improved its cell proliferation effect in vitro, suggesting potential for treating hair growth disorders.
