930-960 / 1000+ resultsresearch Photodegradation of hair of different ethnicity after 1 year of exposure to natural weathering in Arizona
Hair with more melanin resists weather damage better.
research Localization of S100A2, S100A4, S100A6, S100A7, and S100P in the human hair follicle.
Different S100 proteins have specific roles in various parts of the hair follicle.
research Rippled‐pattern trichomatricoma
A unique hair tumor with a rippled pattern was identified, showing incomplete differentiation and unusual cell arrangements.
research MLPH-mediated activation of dermal papilla IGF-1 signaling drives human hair shaft elongation and anagen induction
MLPH helps hair grow by activating IGF-1 signaling in hair cells.
research Exploration of potential lipid biomarkers for premature canities by UPLC‐QTOF‐MS analyses of hair follicle roots
Researchers found that certain lipids, especially vitamin D3, are lower in prematurely grey hair than in pigmented hair.
research Postherpetic Poliosis
A man's chest hair turned white after a shingles infection, possibly due to virus-damaged pigment cells.
research Weathering of the hairless scalp: a study using skin capacitance imaging and ultraviolet light-enhanced visualization
The study found that long-term sun exposure does not significantly affect follicular plugs on the scalp, and the scalp's appearance is unique compared to other body parts.
research Pigmentation and Pregnancy
Most skin changes during pregnancy are harmless and moles don't significantly change, but many women experience pigmentation changes due to hormones and sun exposure.
research Percutaneous penetration of hair dyes
Hair dyes penetrate the scalp very minimally, less than 1%.
research Woolly Antics between the Sheaths
Lipase H is important for hair follicle function and shaping hair fibers.
research 857 Human hair follicle regeneration with trichogenic human dermal papilla precursor cells derived from induced pluripotent stem cells
Stem cells can create hair follicles, potentially treating permanent hair loss, and healthy skin and hair depend on mitochondrial function and special fats.
research Spectrum of Phenotypes Associated with Human MC1R Variations
MC1R gene variations affect skin, hair color, UV sensitivity, and melanoma risk.
research Androgen Regulation of the Human Hair Follicle: The Type I Hair Keratin hHa7 Is a Direct Target Gene in Trichocytes
The hHa7 gene is regulated by androgens in certain body hair, not scalp hair.
research Acquired localized hypertrichosis.
A girl grew extra hair in areas where she had insect bites.
research White Hair Follicles in Alopecia Areata.
White hair in alopecia areata may be linked to reduced Sox10 expression.
research A case of altered hair texture after resolution of alopecia areata
New hair after alopecia areata can be thinner and change color but usually keeps the same shape.
research Pigmented Epithelioid Melanocytoma (PEM)/Animal Type Melanoma (ATM): Quest for an Origin. Report of One Unusual Case Indicating Follicular Origin and Another Arising in an Intradermal Nevus
The conclusion is that Pigmented Epithelioid Melanocytoma can start from hair follicle stem cells or from a mole on the skin.
research 137 Loss of myeloid Mcpip1 suppresses hair growth and development of epidermal papilloma of the skin
Removing MCPIP1 from myeloid cells in mice leads to hair loss and prevents skin tumors but causes pigmented spots.
research Regulatory mutations in TBX3 disrupt asymmetric hair pigmentation that underlies Dun camouflage color in horses
Mutations in TBX3 cause horses to have more even hair color instead of Dun camouflage.
research Dissecting the boundary of quiescence and activation of murine melanocyte stem cells in the hair follicle niche
Melanocyte stem cells in hair follicles are key to understanding and potentially preventing hair graying.
research MITF E318K naevus phenotype: the modifying role of MC1R Red Hair Variants
research Follicular ichthyosis
The four patients have a unique type of ichthyosis affecting hair follicles.
research Expression pattern of human hair keratin basic 1 (hHbl) in hair follicle and pilomatricoma
hHbl gene is active in hair shaft cells and some pilomatricomas.
research Bound on the Risk for M-SVMs
The enzyme system in hair follicles is similar to the liver's and is inhibited by certain substances.
research Polyphenolization:Hair Browning by Phenolic Adhesion,Ambient Oxygen, and Transition Metals
A new hair dye method uses polyphenols and oxidation to create a long-lasting brown color on gray hair.
research Amelanocytic Anhidrotic Alopecia Areata-like Phenotype After Allogeneic Hematopoietic Cell Transplant
The immune system can cause permanent skin and hair whitening by attacking pigment cells.
research Pilomatricoma can differentiate not only towards hair matrix and hair cortex, but also follicular infundibulum, outer root sheath and hair bulge
Pilomatricoma can develop into various hair-related structures.
research Determination of the cuticula thickness of human and porcine hairs and their potential influence on the penetration of nanoparticles into the hair follicles
Nanoparticles penetrate hair follicles better when their size matches the cuticula thickness.
research Somatic mutations distinguish melanocyte subpopulations in human skin
Hair follicles protect melanocytes from sun damage, helping them replenish skin.
