research Diffuse hair loss
The document's conclusion cannot be summarized because it is not readable or understandable.
research Towards Defining the Pathogenesis of the Hairless Phenotype
The hairless gene mutation causes baldness by disrupting hair follicle structure.
research Inductive capacity of irradiated dermal papillae
The dermal papilla can still grow new hair even after heavy radiation.
research Exhaustive analysis of scalp hair regression: subjective and objective perception from initial hair loss to severe miniaturisation and drug-induced regrowth
Hair loss reduces hair thickness and coverage, but drug treatments mainly revive dormant hairs rather than reverse thinning; patients often undervalue their hair loss severity.
research Hair growth induction by the tellurium immunomodulator AS101: association with delayed terminal differentiation of follicular keratinocytes and ras‐dependent up‐regulation of KGF expression
The substance AS101 can help hair grow by slowing down hair cell aging and boosting a hair growth protein.
research Types and Characteristics of Hair Across the Globe: Results of a Multinational Study on 19,461 Individuals
Hair affects self-image and well-being, varying by gender, ethnicity, and country.
research Possibilities and Limitations for Reversal of Age-Related Hair Loss
research Female-patterned alopecia in teenage brothers with unusual histologic features
Two teenage brothers had a rare, treatment-resistant form of female-pattern hair loss with unusual scalp changes.
research Variations of scalp, pubic and axillary hair
Pubic hair is thicker than axillary and scalp hair, useful for forensic identification.
research The hair cycle
The document concludes that the hair cycle is a complex process involving growth, regression, and rest phases, regulated by various molecular signals.
research ABC of Dermatology: Diseases of the hair and scalp
The document explains different hair and scalp conditions, including common hair loss after pregnancy or illness, drug-induced hair loss, hereditary excessive hair growth, patterned baldness, autoimmune hair loss, and permanent loss due to skin disease, with generally limited treatment options.
research The hair cycle
The document concludes that the hair cycle is a complex process involving growth, regression, and rest phases, regulated by various molecular signals.
research Nevus comedonicus with lesional growth of terminal hair: An unusual case
Nevus comedonicus can sometimes grow terminal hair, challenging previous beliefs.
research Quantitative Studies on Human Hair Growth(I). Fundamental Measurements and the Evaluation of Hair Growers.
Hair grows slower and thinner with age, but a test tonic improved growth in alopecia subjects.
research Characteristic Microstructure of Curved Human Hair
Curved human hair has different structures on each side, which might cause its shape and is similar to wool.
research Water distribution in human hair microstructure elucidated by spin contrast variation small-angle neutron scattering
The technique showed that human hair has two main parts, with 68% being rigid and the rest flexible, and water swelling affects its structure.
research Classification of hair disease
Classifying hair diseases, like alopecia, is difficult and needs more research to understand their causes.
research Sparse Brittle Hair and Bilateral Temporal Alopecia in a Child
A 2-year-old boy has a rare hair disorder causing brittle hair and hair loss, which may improve with age.
research Synchronous neonatal telogen effluvium in white and black.
Newborns can experience temporary hair loss in bands, unrelated to sleeping position.
research 289 Immortalization of primary human dermal papilla cells by Bmi-1 and TERT
Hair care products reduced hair roughness, a combination of Stemoxydine and Resveratrol increased hair density, fermented mackerel oil promoted hair growth, and genes TERT and Bmi-1 helped create new hair follicles.
research [A longitudinal elasticity study of hair from the human head in forensic medicine].
The method effectively measures hair elasticity and could be useful in forensics.
research Quantitative Studies on Human Hair Growth(II). Correlation between Subjective Grading and Objective Measurements of Hair Growth.
The study concluded that certain hair growth measurements are good indicators of baldness severity and provide a more accurate assessment than subjective grading.
research Female pattern hair loss
The document's conclusion cannot be provided because the content is not accessible.
research Natural hairline density in men: findings of a pilot survey
Men generally have a certain thickness of hair at their hairline.
research HAIR AND HAIR CARE: AN OVERVIEW
Eating well and avoiding synthetic hair products are key for healthy hair.
research The multifaceted role of hair as a biospecimen: recent advances in precision medicine and forensic science
Hair analysis is valuable for health and forensics but faces challenges like growth variability and contamination.
research Nanoindentation of Hair Cortex and Medulla Regions
research "Curly" Wood and Tiger Tails
Tiger tail bands in hair are caused by wavy hair fibers with melanin, unlike straight fibers in normal hair.
research [Contribution to hair medulla study (author's transl)].
Hair medullary cells in mammals vary in complexity, with humans having more structured cells similar to inner root sheath cells.
