research Discovery of HAP Stem Cells
HAP stem cells in hair follicles could help repair nerves and spinal cords.
research The incidental pore: CaV1.2 and stem cell activation in quiescent hair follicles
CaV1.2 helps activate hair follicle stem cells without calcium flux.
research Variation in human hair ultrastructure among three biogeographic populations
Different populations have distinct hair structures related to their ancestry.
research Prognosis and Management of Congenital Hair Shaft Disorders without Fragility—Part II
Some congenital hair disorders improve with age and can be managed with treatments like minoxidil, retinoids, supplements, and gentle hair care, but there's no cure.
research Inherited Disorders of the Hair
The document explains the genetic causes and characteristics of inherited hair disorders.
research The walking dead: sequential nuclear and organelle destruction during hair development
Cells in hair die by breaking down their DNA and mitochondria as they form keratin.
research Hair Follicles Guide Nerve Migration In Vitro and In Vivo in Tissue-Engineered Skin
Hair follicles help guide nerve growth, improving touch recovery in skin grafts.
research Epidermal patterning and induction of different hair types during mouse embryonic development
Different body areas in mice produce different hair types due to interactions between skin layers.
research Hair Disorders
Understanding normal hair growth and loss in children is key to diagnosing and treating hair disorders.
research Long-term renewal of hair follicles from clonogenic multipotent stem cells
Adult stem cells from rat whisker follicles can regenerate hair follicles and sebaceous glands.
research At the dawn of hair research – testing the limits of hair follicle regeneration
Hair follicle regeneration is possible but challenging, especially in humans, due to the need for specific cells and a better understanding of how they signal growth.
research Rare Coexistence of Monilethrix and Trichorrhexis Nodosa in a Pediatric Patient: A Case Report
A 6-year-old girl had both monilethrix and trichorrhexis nodosa, causing brittle hair, with minimal improvement from treatment.
research Study of normal hair and of some malformations with a scanning electron microscope
Hair malformations may occur due to timing issues in hair development.
research Hair-follicle-associated pluripotent (HAP) stem cells
HAP stem cells can repair nerves and spinal cords by becoming Schwann cells.
research The hair shaft: normality, abnormality, and genetics
Hair microscopy is useful for diagnosing hair disorders, but clear definitions are needed for accurate genetic analysis.
research Elisabeth & Antonio: Hotel Las Arenas Wedding
Neuropeptides affect hair growth and could be used to control it.
research Hair microscopy: an easy adjunct to diagnosis of systemic diseases in children
Hair microscopy is a simple and cost-effective method to help diagnose systemic diseases in children.
research Touch Receptors Undergo Rapid Remodeling in Healthy Skin
Touch sensitivity in mouse skin decreases during hair growth due to changes in touch receptors.
research 597 Outer root sheath is able to synthesise glycogen from lactate-investigating glycogen metabolism in human hair follicles
research Hair cosmetic alterations
The document concludes that individualized treatments for hair issues are effective, certain hair changes can indicate neurocutaneous diseases, specific lotions improve skin health, laser hair removal works but needs more study on long-term effects, men's cosmetics are diverse, peeling is effective but can have side effects, and facial pigmentation is often due to overactive skin cells.
