research Automated digital image analysis (TrichoScan®) for human hair growth analysis: Ease versus errors
TrichoScan often makes mistakes and needs improvement for correct hair growth analysis.
research Hes1 regulates anagen initiation and hair follicle regeneration through modulation of hedgehog signaling
Hes1 protein is important for hair growth and regeneration, and could be a potential treatment for hair loss.
research The proteomic profile of hair damage
Bleaching hair damages protein structure, especially keratin, leading to weakened hair.
research Curcuma aeruginosa Roxb. essential oil slows hair-growth and lightens skin in axillae; a randomised, double blinded trial
Curcuma aeruginosa essential oil effectively reduces hair growth and lightens underarm skin.
research The impact of body site, topical melatonin and brushing on hair regrowth after clipping normal Siberian Husky dogs
Topical melatonin and brushing did not affect hair regrowth in Siberian Huskies.
research Geometric classification of scalp hair for valid drug testing, 6 more reliable than 8 hair curl groups
A 6-group hair classification is more reliable for drug testing than an 8-group system.
research Hair shaft abnormalities after chemotherapy and tamoxifen therapy in patients with breast cancer evaluated by optical coherence tomography
Chemotherapy can cause significant hair thinning and changes in hair texture, while tamoxifen has a smaller effect.
research CRISPR/Cas9-mediated Disruption of Fibroblast Growth Factor 5 in Rabbits Results in a Systemic Long Hair Phenotype by Prolonging Anagen
Disrupting the FGF5 gene in rabbits leads to longer hair by extending the hair growth phase.
research The Biology of Hair Growth
Hair growth is influenced by hormones and goes through different phases; androgens can both promote and inhibit hair growth depending on the body area.
research Studies of light scattering from ethnic hair fibers
Different hair types from various ethnic groups affect hair shine due to characteristics like thickness and shape.
research Proteins as Hair Styling Agents
Proteins like BSA and keratin can effectively style hair and protect it, offering eco-friendly alternatives to chemical products.
research Variation and Heritability in Hair Diameter and Curvature in an Australian Twin Sample
Hair diameter and curvature are mostly determined by genetics.
research Aqueous Extract of Red Deer Antler Promotes Hair Growth by Regulating the Hair Cycle and Cell Proliferation in Hair Follicles
Red deer antler extract helps hair grow by extending the growth phase and increasing cell growth in hair follicles.
research Quantitative analysis of the anatomical changes in the scalp and hair follicles in androgenetic alopecia using magnetic resonance imaging
MRI reveals thinner scalps and smaller hair follicles in people with androgenetic alopecia.
research Donor site of follicular unit excision hair transplantation: the relationship between appearance and actual hair density, and hair diameter
Good-looking donor sites for hair transplants usually have higher hair density and thicker hair.
research Is TrichoScan a new diagnostic method for diffuse hair loss?
TrichoScan effectively diagnoses different types of hair loss and is linked to low iron stores in patients.
research Advances in the Chemical Structure of the Hair Surface, Surface Forces and Interactions
