research Exploring the effects of wetting and free fatty acid deposition on an atomistic hair fiber surface model incorporating Keratin Associated Protein 5-1
Water and fatty acids affect hair's surface differently based on hair damage, and models can help understand hair-cosmetic interactions.
research Black women’s hair: the main scalp dermatoses and aesthetic practices in women of African ethnicity
Black women's unique hair characteristics and styling practices can lead to specific scalp conditions, which require early diagnosis and appropriate treatment.
research How different is human hair? A critical appraisal of the reported differences in global hair fibre characteristics and properties towards defining a more relevant framework for hair type classification
Human hair varies widely and should be classified by curl type rather than race.
research Aging of hair
Hair ages due to genetics and environmental factors, leading to graying and thinning, with treatments available for some conditions.
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 Corticosterone inhibits GAS6 to govern hair follicle stem-cell quiescence
Stress hormone corticosterone blocks a growth factor to slow down hair stem cell activity and hair growth.
research An ultrastuctural study of hair fiber damage and restoration following treatment with permanent hair dye
Permanent hair dye damages hair but it mostly recovers after 8 weeks; using certain hair care products can help repair it.
research Induction of Hair Growth by Insulin-Like Growth Factor-1 in 1,763 MHz Radiofrequency-Irradiated Hair Follicle Cells
Radiofrequency exposure can stimulate hair growth by increasing IGF-1 in hair follicle cells.
research Raman spectroscopy and electronic microscopy structural studies of Caucasian and Afro human hair
Hair treatments cause significant structural changes, especially with excessive heat, regardless of ethnicity.
research Hair care practices and structural evaluation of scalp and hair shaft parameters in African American and Caucasian women
African American women report more hair issues and use different hair care practices than Caucasian women, and have different hair and scalp characteristics.
research Protective Role of Nutritional Plants Containing Flavonoids in Hair Follicle Disruption: A Review
Some plants with flavonoids may help treat hair loss and promote hair growth.
research Dihydrotestosterone Regulates Hair Growth Through the Wnt/β-Catenin Pathway in C57BL/6 Mice and In Vitro Organ Culture
Dihydrotestosterone affects hair growth by changing the Wnt/β-catenin pathway, with low levels helping and high levels hindering growth.
research Heat‐damaged evaluation of virgin hair
Heat damages hair, with Asian hair losing more protein than Caucasian hair.
research Lipid loses and barrier function modifications of the brown‐to‐white hair transition
White hair has less lipid content and absorbs water differently than brown hair.
research Exogenous Factors in Hair Disorders
Outside factors like grooming, chemicals, and the environment can damage hair and cause disorders.
research Effect of equilibrium pH on the structure and properties of bleach‐damaged human hair fibers
Hair's structure and properties change with pH; acidic pH maintains strength and less swelling, while alkaline pH increases water content and swelling.
research Bacillus/Trapa japonica Fruit Extract Ferment Filtrate enhances human hair follicle dermal papilla cell proliferation via the Akt/ERK/GSK-3β signaling pathway
The extract from Bacillus/Trapa japonica fruit helps increase hair growth and could be a potential treatment for hair loss.
research The clock gene brain and muscle Arnt-like protein-1 (BMAL1) is involved in hair growth
A gene called BMAL1 plays a role in controlling hair growth.
research Changes of Curvature with Regain of Set Wool and Hair Fibers
Merino wool fibers change shape with moisture, while human hair shape stays the same.
research Isolation and Quantification of Glycosaminoglycans from Human Hair Shaft
Human hair contains more glycosaminoglycans in children than adults, and these compounds decrease with age, possibly affecting hair thickness.
research Exposure to gamma-rays at the telogen phase of the hair cycle inhibits hair follicle regeneration at the anagen phase in mice
Gamma-rays exposure during the resting phase of hair growth can damage hair regeneration and color in mice.
research Evaluation of biophysical skin parameters and hair changes in patients with acne vulgaris treated with isotretinoin, and the effect of biotin use on these parameters
Biotin supplementation during isotretinoin treatment for acne may help maintain skin hydration and improve hair growth.
research The effects of gamma rays on the regeneration of hair follicles are carried over to later hair cycles
Gamma-ray exposure can cause long-lasting damage to hair follicles, affecting hair structure and color.
research Telogen elongation in the hair cycle of ob/ob mice
Obese mice with a leptin gene mutation have a longer resting phase in their hair cycle, which may help understand certain hair loss conditions.
research Straight to the Point: What Do We Know So Far on Hair Straightening?
Hair straightening can damage hair and pose health risks, including exposure to carcinogens and hair loss.
research Extract of Plumbago zeylanica enhances the growth of hair follicle dermal papilla cells with down‐regulation of 5α‐reductase type II
Plumbago zeylanica extract helps hair growth and reduces a hair loss-related enzyme.
research Stiffness of Human Hair Correlates with the Fractions of Cortical Cell Types
Hair stiffness is higher when it has more para-like cortical cells.
research Exposure to 50 Hz electromagnetic fields enhances hair follicle regrowth in C57BL/6 mice
Exposure to 50 Hz electromagnetic fields may help mice grow hair faster.
research Single hair fiber assessment techniques to discriminate between mineral oil and coconut oil effect on hair physical properties
Coconut oil makes hair stronger and more flexible than mineral oil.
