This study found that long-term morbidity from scalp skin harvesting for grafts is low, with high patient satisfaction, and androgenetic alopecia is unlikely to uncover underlying harvest-related hair loss.

This review discusses madarosis, its diverse causes, and suggests follicular unit transplantation as a useful treatment for scarring types, but reports no new clinical results.

This abstract is a placeholder and contains no research findings; it only includes journal-related navigation and subscription information.

This case report describes a rare aggressive variant of squamous cell carcinoma on the scalp of a non-immunosuppressed older male, highlighting its high biological risk for metastasis and poor outcomes.

Treatment improved some symptoms but not all.

This study reported that squamous cell carcinomas of the scalp can be extraordinarily aggressive, potentially metastasizing and causing death, highlighting the need for early diagnosis and careful treatment approaches.

This study highlights that beard hairs are a preferred nonscalp donor source for hair transplantation, especially when scalp donor supply is insufficient due to severe androgenetic alopecia, with careful planning and technique needed to minimize scarring and enhance outcomes.

This chapter reviews causes of poor scarring in hair restoration procedures and discusses methods for improving donor site scars, reporting no new clinical results.

This study reports a case of generalized dermatitis in a mixed-breed German Spitz due to Sarcoptes scabiei and Malassezia sp. infection, treated with ivermectin and fluconazole, plus supportive therapies, resulting in marked lesion reduction though not full recovery.

The man has patchy hair loss likely due to alopecia areata.

This case report describes a 5-year-old girl with lipoid proteinosis, characterized by a raspy voice, thinning scalp hair, and recurrent crusted lesions leading to pock-like scars.

This article discusses various techniques to achieve a cosmetically attractive single donor scar in hair restoration surgery, reporting no new clinical findings.

This study found that mutations affecting hair keratin expression on Chromosome 15 in mice may cause altered hair and skin features similar to other known mouse mutations.

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

This study identifies a new mutation in the Scd1 gene in a strain of Kunming mice, causing skin and hair defects with the mildest impact among similar mutations.

This study found that their novel 3D-imaging method, ASAXA-μCT, identified shrinkage of sweat glands as a key factor in skin aging, which leads to dermal defects, decreased elasticity, and increased wrinkling and sagging.

This study found that hair plucking via waxing led to greying of hair in castrated mice, suggesting that decreased androgen levels may contribute to age-related hair greying in humans.

Non-scarring alopecia can regrow hair, but scarring alopecia is often permanent and needs quick treatment.

This study found that aging mice experience slower and more fragmented hair cycle waves, but transplanting aged skin to a young host can partially restore hair cycling, implicating extracellular factors.

This article describes using hair transplantation as a novel method to improve the appearance of acne scars, but it reports no clinical results.

This study reported that squamous cell carcinomas of the scalp can become extraordinarily aggressive, highlighting the need for early diagnosis and careful use of treatment strategies like wide excision and radiation therapy.

Mutations in the Sgk3 gene cause fuzzy hair in mice.

This review outlines the classification, histopathologic presentation, and pathogenetic concepts of scarring and nonscarring alopecias, reporting no new clinical results and emphasizing the need for clinicopathologic correlation.

In this study, hyperplastic layers of scabietic sheep skin showed expansive keratin labeling, indicating altered keratin expression compared to healthy skin.

In this veterinary case report, the treatment of a 3-year-old male cat named Chipmunk for scabiosis, otitis externa, toxocariosis, and ancylostomiasis using ivermectin, diphenhydramine, drontal, and additional medications was found to be clinically effective.

This review explores the trichoscopic features of dark scalp, particularly the brown honeycomb pigment network, and its variations in different types of alopecia, but it presents no new clinical findings.

This report describes a rare case of scarring alopecia, diagnosed as lichen planopilaris (LPP), affecting solely the limbs, highlighting the necessity for thorough evaluation of LPP beyond the scalp.

This case report describes a cat with localized scleroderma (morphea-like) that did not show clinical resolution or spontaneous remission after treatment, differing from previously documented cases.

This study identifies iRhom2 as a crucial regulator of hair follicle differentiation, showing that the iRhom2Uncv mutation leads to dysplasia and reduced TACE maturation, resulting in a hairless phenotype in mice.
