research Paracrine crosstalk between human hair follicle dermal papilla cells and microvascular endothelial cells
Cells from the base of hair follicles help blood vessel cells survive and grow, which is important for healthy hair.
research A Nonrandomized study of trichoscopy patterns using nonpolarized (contact) and polarized (noncontact) dermatoscopy in hair and shaft disorders
Polarized dermoscopy is slightly better than nonpolarized for diagnosing hair disorders, with each method having its own strengths.
research Keratin formation in the hair follicle
Keratin fibrils in hair form and stop growing at specific points in the follicle.
research Office Diagnosis of Hair Shaft Defects
The document explains how to identify different hair problems using a microscope.
research The lack of significant changes in scalp hair follicle density with advancing age
Aging alone barely affects the number of hair follicles, meaning hair loss is minimal without other conditions like androgenetic alopecia.
research Effect of Latanoprost on Hair Growth in the Bald Scalp of the Stump-tailed Macacque: A Pilot Study
Latanoprost, a glaucoma drug, showed potential for promoting hair growth in bald monkeys, especially at higher doses.
research Melatonin promotes Cashmere goat (Capra hircus) secondary hair follicle growth: a view from integrated analysis of long non-coding and coding RNAs
Melatonin helps Cashmere goats grow more hair by affecting certain genes and cell pathways.
research Toxicological Studies on Procyanidin B-2 for Extern?al Application as a Hair Growing Agent
Procyanidin B-2 is safe to use on skin as a hair growth product.
research Responses of hair follicle–associated structures to loss of planar cell polarity signaling
Loss of Fz6 disrupts hair follicle and associated structures' orientation.
research The zombie commodity: hair and the politics of its globalization
The article concludes that the global hair trade is exploitative and reflects complex cultural and economic issues.
research The Hair Follicle
Dogs could be good models for studying human hair growth and hair loss.
research Engineering the niche for hair regeneration — A critical review
Further research is needed to improve hair regeneration using stem cells and nanomaterials.
research Promotion of anagen, increased hair density and reduction of hair fall in a clinical setting following identification of FGF5-inhibiting compounds via a novel 2-stage process
New compounds were found to help increase hair growth and decrease hair loss.
research Hair Loss in Systemic Disease
Systemic diseases can cause hair loss, which is often reversible with treatment.
research NF-κB Participates in Mouse Hair Cycle Control and Plays Distinct Roles in the Various Pelage Hair Follicle Types
NF-κB is crucial for different stages and types of hair growth in mice.
research Predicting hair cortisol levels with hair pigmentation genes: a possible hair pigmentation bias
Darker hair may lead to higher cortisol readings, suggesting a need to adjust for hair color in studies.
research Effects of Finasteride on Apoptosis and Regulation of the Human Hair Cycle
Finasteride helps hair growth by decreasing cell death in hair follicles.
research ARCHAEOLOGICAL AND CONTEMPORARY HUMAN HAIR COMPOSITION AND MORPHOLOGY
Mummy hair's chemical composition may not accurately show ancient people's health due to environmental contamination.
research Hair follicular cell/organ culture in tissue engineering and regenerative medicine
Stem cell therapy is a promising approach for hair regrowth despite potential side effects.
research Effects of Finasteride on Apoptosis and Regulation of the Human Hair Cycle
Finasteride affects hair growth by changing caspase and XIAP levels, potentially treating hair diseases.
research Distinguishing diffuse alopecia areata (AA) from pattern hair loss (PHL) using CD3+ T cells
CD3+ T-cell presence is a reliable marker to tell apart alopecia areata from pattern hair loss.
research Donor hair follicle preservation by partial follicular unit extraction. A method to optimize hair transplantation
Partial hair follicle extraction can effectively double the number of hair follicles for transplants, with most surviving and growing normally after a year.
research Annurca Apple Polyphenols Ignite Keratin Production in Hair Follicles by Inhibiting the Pentose Phosphate Pathway and Amino Acid Oxidation
Annurca apple extract promotes hair growth by changing hair follicle metabolism to boost keratin production.
research Distribution of Glycolipid and Unsaturated Fatty Acids in Human Hair
Human hair has more unsaturated fats inside than on the surface, and certain lipids may help bind the outer and inner layers together.
research Advances in Hair Restoration
New techniques improve hair restoration success.
research Induction of osteoblastic differentiation of neural crest-derived stem cells from hair follicles
Hair follicle cells can become bone-like cells, useful for bone repair.
research The tumescent technique facilitates hair micrografting
The tumescent technique improves hair micrografting by providing lasting anesthesia, reducing bleeding, and increasing patient comfort.
research Establishment of keratinocyte cell lines from human hair follicles
Scientists created keratinocyte cell lines from human hair that can differentiate similarly to normal skin cells, offering a new way to study skin biology and diseases.
research Premature Hair Whitening is an Independent Predictor of Carotid Intima-media Thickness in Young and Middle-aged Men
Early hair whitening may indicate a higher risk of heart disease in young and middle-aged men.
