research Quantitation of normal human hair pigmentation by electron microscopy
Daily hair care may cause holes in hair fibers.
research Faculty Opinions recommendation of Hyperactivation of sympathetic nerves drives depletion of melanocyte stem cells.
Stress causes hair graying by overactivating nerves that deplete color-giving stem cells.
research Urticaria Neonatorum: Accumulation of tryptase‐expressing mast cells in the skin lesions of newborns with Erythema Toxicum
Newborns with the common rash Erythema Toxicum have many active mast cells in their skin, but these cells don't produce the LL-37 peptide.
research Dermoscopy Research—An Update
Dermoscopy has greatly improved the diagnosis of skin lesions and our understanding of their morphology and biology.
research Protective Role of Melatonin and Its Metabolites in Skin Aging
Melatonin, a hormone, can help protect skin from aging by reducing stress, inflammation, and damage, and may also help treat hair loss in women.
research Staining of human skin with RGB trichrome unveils a proteoglycan-enriched zone in the hair dermal sheath
A new staining method shows a special area in the hair's skin layer with lots of proteoglycans.
research Merkel cell differentiation in trichoblastoma
Trichoblastomas may mimic fetal skin development by having many Merkel cells, unlike adult skin.
research Local inflammation exacerbates cutaneous manifestations in a murine autoimmune pemphigus model
Local inflammation worsens autoimmune skin conditions by increasing antibody buildup.
research BH21 Segmented heterochromia with calibre change: an under-recognized sign of alopecia areata
Segmented hair color changes can indicate active alopecia areata.
research Hair Graying Regulators Beyond Hair Follicle
Hair graying is influenced by factors like nerves, fat cells, and immune cells, not just hair follicles.
research Subungual melanocytic lesions
Early subungual melanoma might be treated with less aggressive surgery because it invades the skin under the nail more slowly.
research Maternal Melatonin Contributes to Offspring Hair Follicle Development Through Transcriptional Regulation of the AP-1 Complex and MAPK Pathway
Maternal melatonin improves offspring hair growth by affecting specific proteins and pathways.
research Implication of microRNA regulation in para-phenylenediamine-induced cell death and senescence in normal human hair dermal papilla cells
Hair dye ingredient PPD causes cell death and aging in human hair cells by altering microRNA levels.
research Potential Role of the Epidermal Differentiation Complex in the Pathogenesis of Psoriasis
The role of certain genes in skin cell development may be linked to psoriasis, but the connection is unclear.
research Segmental Becker’s Nevi with Mucosal Involvement
A 16-year-old boy had a rare case of Becker's nevus on his face and mouth.
research Boosting hair growth through follicular delivery of Melatonin through lecithin-enhanced Pickering emulsion stabilized by chitosan-dextran nanoparticles in testosterone induced androgenic alopecia rat model
Melatonin in a special emulsion can help treat hair loss more effectively.
research O04 HPV8 E6 leads to Lrig1+ keratinocyte stem cell expansion
HPV8 E6 gene causes growth of certain skin stem cells.
research Epidermal Nevi
Epidermal nevi are skin cell clusters linked to various syndromes.
research Vemurafenib-induced pityriasis amiantacea: a case report
Vemurafenib can cause scalp issues but can be managed without changing the dose.
research Reversible cutaneous hyperpigmentation and nails with white hair due to vitamin B12 deficiency.
Vitamin B12 deficiency can cause skin darkening and white hair, but it's reversible.
research Qualitative investigation of fresh human scalp hair with full-field optical coherence tomography
Melanin density affects hair color, and this method can help in cosmetic assessments and diagnosing hair diseases.
research Variation in human hair ultrastructure among three biogeographic populations
Different populations have distinct hair structures related to their ancestry.
research Associations between sun sensitive pigmentary genes and serum prostate specific antigen levels
Men with less sun-sensitive skin have lower PSA levels, while men with more sun-sensitive skin have higher PSA levels.
research Melanocortin receptor type 2 (MC2R, ACTH receptor) expression in patients with alopecia areata
Lower MC2R expression may contribute to alopecia areata.
research EVALUATION OF GUT MICROBIOTA IN MELANOMA AND VITILIGO PATIENTS
Melanoma and vitiligo patients have different gut fungi and bacteria compared to healthy people.
research Epidermal growth factor promotes proliferation of dermal papilla cells via Notch signaling pathway
A substance called epidermal growth factor helps increase the growth of important hair follicle cells by activating a specific cell communication route.
research Suprabasal Desmoglein 3 Expression in the Epidermis of Transgenic Mice Results in Hyperproliferation and Abnormal Differentiation
Overexpressing Dsg3 in mice skin causes excessive cell growth and abnormal skin development.
research Epigen Transgenic Mice Develop Enlarged Sebaceous Glands
Overexpressing the epigen gene in mice leads to enlarged sebaceous glands and greasy fur.
