This article reviews the structure and function of hair follicles, diagnostic approaches, and treatments for nonscarring alopecias, but reports no new clinical results.

Dermoscopy is useful for many health professionals, not just dermatologists, in improving skin condition diagnoses and reducing unnecessary biopsies.

Polyquaternium 7® builds up on hair, improving its look and feel, and AFM is good for measuring these changes.

This study analyzed skin biopsies from human monkeypox virus (hMPXV1) cases and found characteristic pustular stage features, including epidermal necrosis, shadow cell appearance, ballooned keratinocytes, and a dense inflammatory infiltrate, expanding histological knowledge crucial for understanding this disease and related Orthopoxvirus infections.

This article outlines a protocol for scanning electron microscopy of murine skin and primary keratinocyte monolayers, providing a guide for sample preparation and examination.

This study found that plasma jets can effectively clean and oxidize human hair fibers, with argon/oxygen plasma having the strongest effects, suggesting potential as an alternative to peroxide treatment.

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 review discusses the causes of hair shaft abnormalities and highlights the role of cosmetic products in treating hair disorders, though it reports no new clinical findings.

The document concludes that hair restoration has improved with follicular unit transplantation, making it more scientific and precise.

This review discusses various forensic applications of hair analysis, such as species identification and drug addiction testing, and reports no new study results.

This review article examines the current understanding of frontal fibrosing alopecia, noting its prevalence in different demographics and the roles of genetic and environmental factors in its pathogenesis, while highlighting that treatment approaches remain varied and lack standardization.

This study is the first to document alopecia in Guadalupe fur seals in the Northeast Pacific Ocean, finding that it may result from nutritional stress due to higher sea surface temperatures.

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.

In this study, the researchers developed and optimized a curcumin nanocrystal gel to enhance skin permeability, reporting improved dissolution properties and antiproliferative effects on cell lines, suggesting it as a promising topical delivery system.

This case report described a young Himalayan kitten in Indonesia with notoedric mange, treated successfully with topical selamectin and sarolaner, highlighting the importance of early diagnosis and management to prevent reinfestation, especially in urban areas.

In this study, researchers examined juglone's potential as a restoring agent for hair keratin damaged by permanent or bleaching treatments, finding that juglone formed Michael adducts with cysteine residues, leading to a more regular hair surface as observed via IR spectroscopy and SEM analysis.

This study documented the first confirmed infections of Trichophyton bullosum in donkeys in Africa, indicating equines as primary hosts and highlighting the potential underestimation of this pathogen's prevalence.

This review examines various methods for assessing hair growth in women, highlighting the usefulness of the mFG visual scoring method for diagnosing hirsutism despite its limitations.

This study found statistically significant patterns in hair morphology and ultrastructure linked to biogeographic ancestry among European, African, and East Asian populations.

Hair fibers interact through classical forces, which are influenced by treatments and products, important for hair care and other applications.

This review discusses a clinical approach to diagnosing alopecia through patient history and clinical findings, but it reports no new clinical results.

This review covers the current procedure for follicular unit hair transplantation, noting that recent advancements have made the results natural and undetectable, but it presents no new experimental findings.

This study used two-photon microscopy to reveal that the dermal papilla is crucial for hair follicle regeneration and cannot be replaced by neighboring cells, providing new insights into stem cell behavior.

This review outlines a systematic method for diagnosing hair loss and presents no new findings; the authors emphasize the importance of biopsy in cicatricial alopecia cases.

This review summarizes recent advancements in follicular targeting for drug delivery via hair follicles and calls for pilot studies in humans to explore potential clinical applications.

This study used light sheet fluorescence microscopy to successfully image and analyze calcium oscillations in the root hairs of Arabidopsis thaliana, finding that these oscillations correlate with the root hair growth rate and that auxin affects these properties.

This protocol describes using two-photon laser-scanning microscopy to study hair regeneration in live mice, offering detailed imaging capabilities for observing hair follicle stem cell behavior and manipulating cellular populations.

This study found that increasing a drug's lipophilicity and adding ethanol to the donor phase can enhance its delivery to the hair follicle, although the precise transport mechanism remains unclear.

This study concluded that bleach treatment partly transforms the hydrophobic top layer of human hair cuticles into a hydrophilic surface with clustered cysteic acid, visualized at the nano-scale using dynamic Chemical Force Microscopy.

In this study, R-CSLM showed promise in evaluating hair shaft diseases by providing high-quality images of hair structures, although further development is necessary for follicle and perifollicular area analysis.
