research Root hair growth in Arabidopsis thaliana is directed by calcium and an endogenous polarity
Calcium affects where root hairs grow, but other unknown factors determine their growth direction.
research A genome-wide association scan in admixed Latin Americans identifies loci influencing facial and scalp hair features
Genetic factors influence hair traits like shape, color, and greying in Latin Americans.
research The Effect of Autologous Activated Platelet Rich Plasma (AA-PRP) Injection on Pattern Hair Loss: Clinical and Histomorphometric Evaluation
AA-PRP injections effectively increase hair count and thickness for male pattern hair loss.
research Comparative Proteomics Indicates That Biosynthesis of Pectic Precursors Is Important for Cotton Fiber and Arabidopsis Root Hair Elongation
Pectin biosynthesis is essential for the growth of cotton fibers and Arabidopsis root hairs.
research Keratin 17 modulates hair follicle cycling in a TNFα-dependent fashion
Keratin 17 is crucial for normal hair growth by regulating hair cycle transitions with TNFα.
research Enhanced Effect of Platelet-Rich Plasma Containing a New Carrier on Hair Growth
Platelet-rich plasma with a new carrier significantly increases hair thickness without serious side effects.
research Light scattering from human hair fibers
Researchers developed a new model for more realistic computer graphics rendering of hair by considering how light scatters on hair fibers.
research Theoretical considerations in laser hair removal
Laser hair removal effectiveness depends on targeting hair structures without harming the skin, and improvements require more research and expert collaboration.
research Hedgehog stimulates hair follicle neogenesis by creating inductive dermis during murine skin wound healing
The Sonic hedgehog pathway is crucial for new hair growth during mouse skin healing.
research Hair anatomy for the clinician
Understanding hair follicle anatomy helps diagnose hair disorders.
research Stem cell dynamics in the hair follicle niche
Stem cells in the hair follicle are regulated by their surrounding environment, which is important for hair growth.
research Human hair follicle organ culture: theory, application and perspectives
Human hair follicle organ culture is a useful model for hair research with potential for studying hair biology and testing treatments.
research Differential Auxin-Transporting Activities of PIN-FORMED Proteins in Arabidopsis Root Hair Cells
Different PIN proteins affect plant root hair growth by changing how auxin is transported.
research Corkscrew Hair: A New Dermoscopic Sign for Diagnosis of Tinea Capitis in Black Children
Corkscrew hair may be a new sign for quickly diagnosing scalp fungus in black children.
research Hair Follicle Regeneration Using Grafted Rodent and Human Cells
Grafted rodent and human cells can regenerate hair follicles, but efficiency decreases with age.
research Control of hair follicle cell fate by underlying mesenchyme through a CSL–Wnt5a–FoxN1 regulatory axis
Notch/CSL signaling controls hair follicle differentiation through Wnt5a and FoxN1.
research Effects of EGF on the Morphology and Patterns of DNA Synthesis in Isolated Human Hair Follicles
EGF makes hair follicles grow longer but stops hair production.
research Ozone interactions with human hair: Ozone uptake rates and product formation
Ozone reacts more with unwashed hair, producing compounds due to scalp oils, which could lower ozone exposure but increase exposure to reaction products.
research Light scattering from human hair fibers
Researchers developed a new model for more realistic computer graphics of hair by considering how light scatters on hair fibers.
research White Lupin Cluster Root Acclimation to Phosphorus Deficiency and Root Hair Development Involve Unique Glycerophosphodiester Phosphodiesterases
White lupin uses specific genes to grow root hairs and access phosphorus when it's scarce.
research Hair follicles’ transit-amplifying cells govern concurrent dermal adipocyte production through Sonic Hedgehog
Cells in hair follicles help create fat cells in the skin by releasing a protein called Sonic Hedgehog.
research Regenerative Hair Waves in Aging Mice and Extra-Follicular Modulators Follistatin, Dkk1, and Sfrp4
Aging mice have slower hair regeneration due to changes in signal balance, but the environment, not stem cell loss, controls this, suggesting treatments could focus on environmental factors.
research A clinical overview of hair removal using lasers and light sources
Lasers and light sources can effectively remove hair, work best on fair skin with dark hair, and usually need multiple treatments.
research The Formation of Vellus Hair Follicles from Human Adult Epidermis1
Adult human skin can grow new fine hair follicles after a deep exfoliation treatment.
research A Human Folliculoid Microsphere Assay for Exploring Epithelial– Mesenchymal Interactions in the Human Hair Follicle
HFMs can help study hair growth and test potential hair growth drugs.
research Evaluation and diagnosis of the hair loss patient
Trichoscopy is a quick, cost-effective tool for diagnosing different hair loss conditions.
research Transcutaneous implantation of valproic acid-encapsulated dissolving microneedles induces hair regrowth
Tiny needles with valproic acid can effectively regrow hair.
research Development and evaluation of polyherbal formulation for hair growth–promoting activity
The herbal formulation promoted hair growth faster and more effectively than minoxidil in rats.
research The hair cycle on the human thigh and upper arm
Men's thigh hair grows longer and has a longer growth cycle than women's, but arm hair growth is similar between genders.
