research Determining Safe Excision Limits in FUE: Factors That Affect, and a Simple Way to Maintain, Aesthetic Donor Density
Researchers concluded that safe hair follicle extraction limits in FUE vary by individual characteristics and proposed a method to calculate these limits to maintain appearance.
research The Distribution of Follicular Units in the Chinese Scalp: Implications for Reconstruction of Natural-Appearing Hairlines in Orientals
Chinese patients have fewer hair follicles than Caucasians, and transplanting hair at 40% of normal density works for natural-looking hairlines.
research Red Dots in a Net-Like Pattern on the Upper Chest: A Novel Clinical Observation in Frontal Fibrosing Alopecia and Fibrosing Alopecia in Pattern Distribution
Red dots on the upper chest may be an early sign of certain types of hair loss.
research Hypopigmentation in frontal fibrosing alopecia
FFA patients have fewer melanocytes and thinner skin compared to others.
research The Density Issue — A Debate That Refuses To Die
The debate over density remains unresolved.
research The distribution of hair in Han Chinese
Healthy Han Chinese have lower hair density than whites and Africans, and transplanting 300 hair units can nearly restore normal hair density.
research Organization of microfibrils in keratin fibers studied by X-ray scattering
The study improved understanding of keratin fiber structure by showing consistent microfibril diameter but varying distances and electron density profiles.
research An observational analysis of erythromelanosis follicularis faciei et colli
EFFC might be common but underreported.
research Erythromelanosis follicularis faciei et colli with reticulated hyperpigmentation of the extremities
A rare skin condition causes red and dark patches on the face and limbs.
research Phototrichogram analysis of normal scalp hair characteristics with aging
Hair gets thinner and grayer with age, and density decreases more in men on top and in women on top and back.
research Distribution of Human Hair in Follicular Units
The research found that for a typical hair density, about 11 square centimeters of donor scalp is needed to get 800 hair grafts for transplantation.
research Assessment of hair density and caliber in Caucasian and Asian female subjects with female pattern hair loss by using the Folliscope
Caucasian hair is denser, but Asian hair is thicker in female pattern hair loss patients.
research Qualitative investigation of fresh human scalp hair with full-field optical coherence tomography
Melanin density affects hair color, and this method can help in cosmetic assessments and diagnosing hair diseases.
research Increased Preauricular Wrinkles in Frontal Fibrosing Alopecia Compared to Age-Matched Controls: A Prospective Study of 64 Patients
Women with Frontal Fibrosing Alopecia have more wrinkles near their ears than similar aged women without the condition.
research Studies of light scattering from ethnic hair fibers
Different hair types from various ethnic groups affect hair shine due to characteristics like thickness and shape.
research Erythromelanosis Follicularis Faciei et Colli: A Case Report in a Caucasian Male and Brief Review of the Literature
A rare skin condition causes red, dark, bumpy facial lesions.
research A Comparison of Reticle Size to Determine Follicular Unit Density in Hair Restoration
Smaller reticle sizes are as accurate as the standard size for measuring hair density in hair restoration.
research Scattering from Elliptical Hair Fibers Based on Microfacet Theory
research The Density Issue in Hair Transplantation
Mini-micrografting in hair transplants can give similar density to older methods with fewer sessions.
research P130 The densities of T cells, Langerhans cells, and natural killer cells in uninvolved skin of patients with acne vulgaris
People with acne have more CD4+ immune cells in their skin than healthy people.
research Assessment of Follicular Unit Density in Asian Men with Androgenetic Alopecia
Asian men have varying hair densities, important for hair transplant success.
research Serum ferritin levels amongst individuals with acne
People with acne tend to have lower iron levels.
research 689 Regional differences in scalp innervation: A pilot study of the healthy scalp
The back of the scalp has more nerve fibers than the front, which may explain why some people feel more sensitivity there.
research The changing patterns of hair density and thickness in South Korean women with hair loss: clinical office-based phototrichogram analysis
South Korean women with hair loss have lower hair density and thickness compared to healthy women.
research Regarding the Death of Density Debate
Achieving original hair density with transplants is unrealistic; skilled practitioners are essential for the best results.
research MITF E318K naevus phenotype: the modifying role of MC1R Red Hair Variants
research Variations in the optical scattering properties of skin in murine animal models
Male mice have thicker skin, causing more light scattering than females.
research Avaliação quantitativa em cortes histológicos transversais do couro cabeludo
The study found average numbers for different types of hair follicles in the scalp and observed differences between men and women, suggesting reasons for more common hair shedding in women.
research Field melanin mapping of the hairless scalp
The study found a specific pattern of uneven melanin distribution on balding scalps that could help understand skin diseases caused by light exposure.
