This literature review reports that mutations in the SASH1 gene are linked to different pigmentation disorders, including dyschromatosis universalis hereditaria and lentiginosis. It further suggests SASH1's significant role in melanocyte processes and its potential as a target for developing treatments for these conditions.

This review discusses alopecia areata as a model for studying tissue-directed autoimmune diseases and reports no new clinical findings.

In this study, male-pattern baldness was strongly associated with a higher risk of keratinocyte cancers, particularly squamous cell carcinoma and melanoma, likely due to increased sun exposure on the scalp rather than androgen levels.

This case report presents the first documented instance in India of cutaneous amyloidosis causing pigmented papules on the ear pinna, with lesions resolving after treatment with topical tretinoin.

This article reviews common hair growth abnormalities in children, emphasizing the importance of distinguishing normal development from potential signs of metabolic disorders and indicates no new clinical results.

This study observed that specific dermoscopic features, such as altered pigmentary network and yeast invasion of hair follicles, along with certain histopathological features, assist in diagnosing pityriasis versicolor.

This review discusses the role of Cytochrome P-450 in dermatology and reports no new clinical results.

This article reviews the design and objectives of the Rotterdam Study, as well as summarizes major findings, without reporting new results.

Dermatoscopy and videodermatoscopy are useful for diagnosing and monitoring various skin, hair, and nail conditions.

This article reviews the use of trichoscopy for diagnosing various types of alopecia and reports no new clinical results; it is suggested as a non-invasive method for diagnosis and monitoring treatment responses.

This study found that human iPSC-derived melanocytes from vitiligo patients successfully integrated into mouse hair follicles and epidermis, demonstrating potential for personalized therapy for depigmentation.

In this study, oral zinc sulphate was found to cause hair hypopigmentation and significantly inhibit eumelanogenesis in mice.

This review discusses genome-wide association studies in dermatology, noting that variants linked to risk for 10 skin complex diseases have been identified, with potential implications for diagnostics and management; it reports no new clinical results.

This study found that genetically variant peptides from human hair can reliably identify individuals despite differences in age and storage conditions, provided environmental and processing factors are controlled.

This report describes four cases of patchy, non-scarring alopecia areata that spared gray hairs and affected only pigmented hairs.

This study found that hair proteome profiling and genetically variant peptide identification in hairs remained effective after an explosive blast, indicating potential for forensic human identification despite damage.

This review outlines the clinical and histopathological features that aid in classifying tumors arising from the folliculosebaceous apparatus and reports no new research results.

This study identified a novel SCF mRNA splice variant in white merino sheep skin, which may play a role in hair follicle melanogenesis.

This report presents four cases highlighting diagnostic challenges between specific types of alopecia, comparing their clinical and histopathologic features without providing new research findings.

This article discusses vitiligo, reviewing its symptoms, possible causes, and classification, but reports no new clinical findings.

Chemotherapy patients don't all lose their hair due to factors like hair growth rates, age, genetics, and the type of drugs used.

In this study, the researchers found that rare genetic variants make a minor contribution to male-pattern hair loss risk, identifying five significant gene associations, including novel genes, and noting a shared basis with monogenic hair loss disorders.

This review summarizes fundamental concepts and recent advancements in hair follicle biology, including insights from mouse models into broader molecular and cellular processes relevant to regeneration and development.

This review discusses the various stem cell populations associated with hair follicles and their potential in regenerative medicine, highlighting differences between murine and human hair follicles but reports no new clinical results.

In this study, T3 and T4 were found to directly influence human hair follicles in vitro, enhancing keratinocyte proliferation, prolonging the hair growth phase, and affecting pigmentation.

Hair color production is closely linked to the active growth phase of hair in mice and may also influence hair growth itself.

This study observed that eliminating positional error in hair segment analysis can improve understanding of changes in isotopic composition, aiding the identification of pathological conditions and dietary patterns.

Fibroblasts can be turned into melanocytes for potential skin treatments.

This study demonstrated that engineered skin substitutes using human keratinocytes and murine dermal papilla cells can develop pigmented hairs without sebaceous glands, suggesting separate pathways for hair development and eruption.

This study found that the application of calreticulin significantly improved wound healing time and quality in diabetic mice, suggesting it may be an effective topical treatment for chronic wounds.
