research Spurenelementkonzentration im Haar bei Patienten mit Schilddrüsenerkrankungen
Trace element levels in hair differ in people with thyroid diseases.
research Impact of acid (”progressive brush”) and alkaline straightening on the hair fiber: Differential effects on the cuticle and cortex properties
Glyoxylic acid straighteners cause more protein loss but have similar hair strength effects as traditional alkaline straighteners.
research 1328 HIF1A stabilisation in the human hair follicle promotes glycolysis
Stabilizing HIF1A in hair follicles increases glycolysis, which may help reduce oxidative stress and support hair growth.
research pH Dependence of the Coiled-Coil Structure of Keratin Intermediate Filament in Human Hair by 13C NMR Spectroscopy and the Mechanism of Its Disruption
Keratin structure in hair is stable at pH 5-6 but disrupts between pH 6-7.
research Effects of Molybdenum and Sulfate Sulfur on Metabolism of Copper in Dairy Cattle
High molybdenum and sulfate sulfur levels can cause health issues in cattle, but adding copper helps.
research Raman spectroscopic analysis of L‐phenylalanine and hydrolyzed eggwhite protein penetration into keratin fibers
L-phenylalanine and hydrolyzed eggwhite protein deeply penetrate human hair.
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 Cryo-Electron Microscopy of Trichocyte (Hard α-Keratin) Intermediate Filaments Reveals a Low-Density Core
Trichocyte filaments have a low-density core and may include proteins for hair structure.
research Update on detection, morphology and fragility in pili annulati in three kindreds
Careful light microscopy is crucial for detecting mild cases of pili annulati, which weakens hair and varies widely in expression.
research 190 Deficiency of the Human Cysteine Protease Inhibitor Cystatin M/E Causes Hypotrichosis and Dry Skin
Not having enough cystatin M/E protein causes less hair growth and dry skin.
research 3 alpha, 17 beta-androstanediol glucuronide in plasma. A marker of androgen action in idiopathic hirsutism.
High levels of 3 alpha-diol glucuronide in the blood are a marker of increased androgen action in women with excessive hair growth of unknown cause.
research The occurrence of the ε-(γ-glutamyl)lysine cross-link in the medulla of hair and quill
research Age-related downregulation of dihydrotestosterone-inactivating enzymes in human scalp sebaceous glands
Age-related changes in scalp glands may affect hair health, but sulforaphane might help.
research Schizochytrium sp. Extracted Lipids Prevent Alopecia by Enhancing Antioxidation and Inhibiting Ferroptosis of Dermal Papilla Cells
Lipids from Schizochytrium sp. help prevent hair loss by protecting hair cells from damage and promoting hair growth.
research ToF‐SIMS characterization of the lipid layer on the hair surface. I: the damage caused by chemical treatments and UV radiation
Chemical treatments and UV radiation severely damage the lipid layer on hair.
research Deficiency of the human cysteine protease inhibitor cystatin M/E causes hypotrichosis and dry skin
Lack of cystatin M/E causes thin hair and dry skin.
research Attenuated Total Reflection Fourier Transform Infrared Spectroscopy Analysis of Human Hair Fiber Structure
Human hair has different protein structures in its cuticle and cortex.
research Hair follicle sulfotransferase activity and effectiveness of oral minoxidil in androgenetic alopecia
Low SULT activity in hair follicles leads to better response to oral minoxidil for hair loss.
research Analysis of the abnormal human hair keratins by two-dimensional polyacrylamide gel electrophoresis
research An ultrahigh-sulphur keratin gene of the human hair cuticle is located at 11q13 and cross-hybridizes with sequences at 11p15
