research Mutations in Sterol O-Acyltransferase 1 (Soat1) Result in Hair Interior Defects in AKR/J Mice
A mutation in the Soat1 gene causes hair structure defects and other health issues in AKR/J mice.
research 6-Gingerol Inhibits Hair Shaft Growth in Cultured Human Hair Follicles and Modulates Hair Growth in Mice
6-Gingerol, found in ginger, may slow down hair growth and could be used for hair removal.
research Secretory phospholipase A2-IIA overexpressing mice exhibit cyclic alopecia mediated through aberrant hair shaft differentiation and impaired wound healing response
Mice with too much sPLA₂-IIA have hair loss and poor wound healing due to abnormal hair growth and stem cell depletion.
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 Age-related changes in the hair follicle and hair shaft in women in the parietal region
As women age, hair follicles decrease in number and hair width tends to reduce.
research Evidence for various calcium sites in human hair shaft revealed by sub-micrometer X-ray fluorescence
The research found two types of calcium in human hair, one that varies among individuals and another that is consistent across people.
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 Alterations in Hair Follicle Morphology and Hair Shaft Production After Follicular Unit Transplantation
Hair transplants can make hair follicles larger and hair shafts thicker.
research A Simple Method to Extract DNA from Hair Shafts Using Enzymatic Laundry Powder
DNA can be quickly and effectively extracted from hair using laundry powder.
research Sample collecting methods for bacterial community structure analysis of scalp hair: non-invasive swabbing versus intrusive hair shaft cutting
Non-invasive swabbing is as effective as cutting hair for collecting scalp hair bacteria.
research INTRODUCING GAP IN HAIR FOLLICLE ELECTROMAGNETISM AS MECHANISM FOR THE PRESENCE OF BIPOLAR ELECTRICAL CHARGES INHERENT IN THE HUMAN HAIR SHAFT
Human hair has bipolar electrical charges because of a gap in the hair follicle's electromagnetic field.
research Comparative studies of hair shaft components between healthy and diseased donors
Hair analysis can help identify specific minerals and amino acids linked to various diseases.
research Physical and mechanical properties of the hair shaft: A review of measurement techniques to verify the efficacy of cosmetic products
Different techniques measure hair properties to ensure cosmetic products work.
research Genetic Ablation of the CDP/Cux Protein C Terminus Results in Hair Cycle Defects and Reduced Male Fertility
Mutant CDP/Cux protein causes hair defects and reduced male fertility in mice.
research The effect of night shift work on the expression of clock genes in beard hair follicle cells
Night shift work disrupts the body's natural clock genes.
research Structural abnormalities of the hair shaft
The document concludes that understanding hair structure is key to diagnosing hair abnormalities and recommends gentle hair care for management.
research Plucked Human Hair Shafts and Biomolecular Medical Research
Human hair follicles may provide a noninvasive way to diagnose diseases and have potential in regenerative medicine.
research Ultrastructural Localization of Hair Keratins in Human Scalp Hair Shafts as Revealed by Rapid-Freezing Immunocytochemistry.
Hair keratins are mainly on macrofibrils in the cortex and in the endocuticle in the cuticle.
research Prognosis and Management of Congenital Hair Shaft Disorders with Fragility—Part I
Some congenital hair disorders improve in childhood or with treatments like minoxidil and retinoids, while others like Netherton syndrome and trichothiodystrophy have a poor prognosis.
research Prognosis and Management of Congenital Hair Shaft Disorders without Fragility—Part II
Some congenital hair disorders improve with age and can be managed with treatments like minoxidil, retinoids, supplements, and gentle hair care, but there's no cure.
research Genetic interplays between Msx2 and Foxn1 are required for Notch1 expression and hair shaft differentiation
Msx2 and Foxn1 are both crucial for hair growth and health.
research Erythropoietin promotes hair shaft growth in cultured human hair follicles and modulates hair growth in mice
