840-870 / 1000+ resultsresearch Hair Cycle and Hair Pigmentation: Dynamic Interactions and Changes Associated with Aging
As people age, their hair follicles produce less pigment, leading to gray and white hair, due to factors like reduced enzyme activity and damage to melanocyte DNA.
research Hair Growth Cycle Affects Hair Follicle Destruction by Ruby Laser Pulses
Ruby laser pulses best destroy hair follicles during the growth phase and effectiveness varies with laser intensity; melanin is key for targeting, and timing treatments can improve results.
research Epidemiology of Skin Cancer in the Mature Patient
Older adults have a high rate of skin cancers like basal cell carcinoma and melanoma, mainly due to UV exposure and age.
research Poliosis Circumscripta: Overview And Underlying Causes
Poliosis circumscripta is a patch of white hair caused by lack of melanin, linked to genetic and acquired conditions.
research Curly Wood and Tiger Tails: The Tiger Tail Phenomenon in Trichothiodystrophy
Tiger tail bands in hair are caused by wavy hair fibers with melanin, unlike straight fibers in normal hair.
research Therapeutic Potential of Patient iPSC-Derived Melanocytes in Autologous Transplantation
Patient-derived melanocytes can potentially treat vitiligo by restoring skin pigmentation.
research Photochemical Alterations in Human Hair: Artificial Irradiation and Investigations of Hair Proteins
Melanin in black hair protects it from sun damage better than light-brown hair.
research Three Streams for the Mechanism of Hair Graying
Hair graying may be caused by stem cell depletion from stress or melanocyte damage.
research Dyeing Regions of Oxidative Hair Dyes in Human Hair Investigated by Nanoscale Secondary Ion Mass Spectrometry
Hair dye colors mainly target melanin granules in black hair.
research Hypopigmentation in Frontal Fibrosing Alopecia
FFA patients have fewer melanocytes and thinner skin compared to others.
research Hoxc13/β-Catenin Correlation with Hair Follicle Activity in Cashmere Goat
Hoxc13 is linked to seasonal hair growth in Cashmere goats and is affected by melatonin.
research Human Skin Color: Origin, Variation, and Significance
Human skin and hair color variation is mainly due to melanin produced by a few genes, with melanin protecting against sun damage.
research Human Hair as a Natural Sun Protection Agent: A Quantitative Study
Hair acts as a significant natural sun barrier, with protection increasing based on hair density, thickness, and melanin presence.
research Hair Pigmentation: A Research Update
Hair color is determined by different melanins and changes with age.
research 3,4,5-Tri-O-Caffeoylquinic Acid Promoted Hair Pigmentation Through β-Catenin and Its Target Genes
A substance called TCQA could potentially darken hair by activating certain genes and increasing melanin.
research Efficacy of an Agonist of α-MSH, the Palmitoyl Tetrapeptide-20, in Hair Pigmentation
Palmitoyl tetrapeptide-20 may help reduce hair greying and increase melanin production.
research Using Morphological Operators and Inpainting for Hair Removal in Dermoscopic Images
The new algorithm removes hair from skin images better than previous methods, helping diagnose melanoma.
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 Heme Oxygenase and the Skin in Health and Disease
HO-1 helps skin health and healing but can worsen melanoma; it's a potential treatment target for skin diseases.
research Human Long-Term Deregulated Circadian Rhythm Alters Regenerative Properties of Skin and Hair Precursor Cells

research A Review of the Etiologies, Clinical Characteristics, and Treatment of Canities
Gray hair is caused by reduced melanin production or transfer issues, linked to aging and possibly health conditions, with treatments focusing on color camouflage.
research Expression of the RORα Gene in Inner Mongolian Cashmere Goat Hair Follicles
The RORα gene is active in different parts of cashmere goat hair follicles and may be influenced by melatonin, especially in December when hair growth changes.
