This study found that ALRN-6924, a clinical-stage dual inhibitor, can selectively protect human scalp hair follicles from paclitaxel-induced toxicity and damage by inducing transient cell cycle arrest in healthy cells without affecting cancer cells, potentially reducing chemotherapy-induced alopecia.

This case report describes a non-thymoma-associated exfoliative dermatitis in an 8-year-old cat, where treatment with cyclosporine A alongside prednisolone and antibiotics resolved skin lesions without relapse after an initial recurrence.

This study adapted a method for culturing melanocytes from human hair follicles to horses, successfully creating partially melanotic equine melanocytes, potentially advancing hair follicle biology research across species.

The skin is the body's largest organ, with layers, cells, and structures that protect and support it.

This review discusses the role of zebrafish as a model for studying human hereditary pigmentary disorders and reports no new experimental results, emphasizing their genetic similarities and the genetic tools available.

This study observed that exposure to heavy metal salts affected skin and hair morphology in mice, with lead acetate decreasing keratinocyte proliferation and zinc sulfate and sodium dichromate increasing it.

This study confirms that human CD34+ melanocyte stem cells can be differentiated into melanin-producing cells, suggesting potential for cellular therapy in treating skin degenerative diseases.

This paper introduces a new understanding that the human hair follicle medulla lacks metabolic activity for H2O2 breakdown, indicating that H2O2 decomposition occurs primarily in the cortical areas.

This abstract contains navigation and subscription information for JAMA Dermatology and reports no new clinical findings.

This letter to the editor shares a case study of lentiginous melanoma that appears clinically malignant but histopathologically benign, involving the BRAFV600R mutation.

This study introduced a noninvasive spectroscopy method to assess hair follicle stages in mice by measuring skin diffuse reflectance and melanin dynamics, offering a potential tool for hair regeneration research.

This review discusses various topics from the 62nd Annual Montagna Symposium on the Biology of Skin, focusing on the diverse effects of light on skin biology, and reports no new clinical results.

This review discusses melanocytes' role in pigmentation, their clinical significance in conditions like vitiligo and hair graying, and highlights current research on hair follicle regeneration without reporting new clinical results.

The document concludes that the skin is a complex organ providing protection, sensation, and healing, with challenges in treating conditions like itchiness.

Hair India 2012 was a successful international event focused on combating fake trichology practices and discussing various hair health topics.

This review discusses the factors influencing human hair color, including genetic components like the MC1R gene and enzyme activity, without presenting new experimental results.

This review discusses the role of melanocytes in skin pigmentation and UV protection, explaining their interactions with keratinocytes and highlighting their involvement in processes like melanin transfer and melanoma development, but reports no new results.

This study suggests that enzyme-modified oriental medical prescriptions could be a promising ingredient for hair products due to their beneficial effects on hair growth and melanogenesis with minimal skin irritation.

This review discusses the mechanisms by which laser treatment affects hair structures and growth, highlighting its potential for permanent hair reduction and associated skin damage, but reports no new experimental results.

This study found that UVB radiation primarily causes hair protein loss, while UVA radiation mainly contributes to hair color changes, with no significant differences in mechanical properties observed between photooxidized and non-irradiated hair.

Melatonin stops melanin production after tyrosinase action, with cyclic GMP mimicking this effect.

This study reviews various hyperpigmentation disorders, their causes, and evolving treatments, emphasizing the need for safe, effective cosmeceuticals particularly suited for adolescents, integrating botanical and phytochemical advancements with modern dermatological techniques.

In this study, researchers analyzed hair follicle development in Yongqing Rex rabbits, finding dynamic changes in fur thickness, coat density, and hair structure across 1 to 6 months, along with fluctuations in follicle density and gene expression linked to hair growth and quality.

This study found that Plerixafor, a CXCR4 antagonist, promotes melanogenesis in melanocytes by increasing MITF and tyrosinase expression and enhancing melanocyte migration, and it effectively restores pigmentation in a mouse depigmentation model without toxicity, highlighting its potential for treating pigmentary disorders.

This study describes a multifunctional hydrogel system designed to treat androgenetic alopecia by integrating nanozymes for reactive oxygen species clearance and melanin nano photothermal agents to enhance hair follicle health, suggesting potential for multi-target precision therapy and improved hair growth.

This study observed that white hair can create an optical illusion of increased scalp visibility, potentially misleading clinical evaluations of hair loss and complicating hair transplantation planning, and identified five core dyeing strategies to address this phenomenon.

This review reports that hair analysis can confirm drug exposure but not accurately estimate doses due to variability and confounding factors like melanin and cosmetic treatments, suggesting it should be used as a qualitative forensic tool rather than for precise dose quantification.

This case report documents an unusual instance of follicular vitiligo in a young woman, characterized by selective hair depigmentation on the forearms, distinctive dermoscopic and Wood's lamp findings, and histological evidence suggesting functional impairment rather than complete loss of follicular melanocytes.

In this study, researchers identified exosomal miR-199a-3p as a key factor in the regulation of melanogenesis by dermal papilla cells, finding that it enhances melanocyte proliferation and melanin production, suggesting potential therapeutic targets for pigmentation disorders.

In this comprehensive review, researchers reported that macromolecules like type I collagen, keratin, and ceramides enhance hair health by improving follicular function and increasing hair density, strength, shine, and resilience, as shown in various in vitro, animal, and human studies.
