research “Anisotrichosis”: A novel term to describe pattern alopecia
The document suggests "anisotrichosis" as a new term for hair thickness variation in common baldness.
research Fine structure of marsupial hairs, with emphasis on trichohyalin and the structure of the inner root sheath
Marsupial hair structure and keratin distribution are similar to placental mammals.
research Plasma and Sonophoresis-Assisted Topical Delivery of an Exosome for Androgenic Alopecia
The treatment improved hair growth and scalp health safely but needs more testing.
research Hair regrowth in male and female pattern hair loss does not involve the conversion of vellus hair to terminal hair
Hair regrowth doesn't convert thin hairs to thick hairs, but increases overall hair density.
research Qualification of a new and precise automatic tool for the assessment of hair diameters in phototrichograms
The new automatic tool accurately measures hair thickness and is reliable.
research Viable terminal scalp hair follicles constitute a necessary and sufficient biological end‐organ that conditions clinical efficacy of finasteride in males with male pattern hair loss without implying reversal of miniaturized follicles
Finasteride works for hair loss by maintaining existing hair follicles, not reversing miniaturization.
research The Quantification of Terminal Hair by Digital Microscopy: Advancements Towards a More Objective Diagnosis of Hirsutism
Digital microscopy can help diagnose hirsutism by measuring hair growth.
research Reduction of Diameter of Hair Shaft among Women with Hirsutism
Aldactone effectively reduces hair thickness in women with excessive hair growth, both alone and with other treatments.
research Parietal scalp is another affected area in female pattern hair loss: an analysis of hair density and hair diameter
Parietal scalp area has lower hair density and smaller hair diameter in women with hair loss.
research Hair diameter measurements for planning follicular unit extraction surgery (FUE): Is there a correlation between the micrometer caliper and scanning electron microscopy (SEM) findings?
The micrometer caliper is a reliable tool for measuring hair diameter for FUE surgery.
research Minoxidil-Induced Trichostasis Spinulosa of Terminal Hair
Minoxidil use can cause trichostasis spinulosa in long-term hair loss patients.
research Evaluation of Scalp Hair Density and Diameter in the Arab Population: Clinical Office-Based Phototrichogram Analysis
Arab hair is generally thicker but less dense compared to other ethnicities, affecting hair disorder diagnosis and treatment.
research Reduction of Diameter of Hair Shaft among Women with Hirsutism
Spironolactone effectively makes hair shafts thinner in women with excessive hair growth.
research Hair density, hair diameter and the prevalence of female pattern hair loss
FPHL affects hair density and diameter, causing visible hair loss in older women.
research Contribution of hair density and hair diameter to the appearance and progression of androgenetic alopecia in Japanese men
Hair thickness matters more than density for baldness in Japanese men over 25.
research Maintenance of optimised hair growth from viable terminal scalp hair follicles at baseline with oral finasteride in male pattern hair loss and first evidence of a “drug dependency” and a post-finasteride “rebound effect”.
Finasteride helps hair growth but stopping it causes faster hair loss.
research Normal head-hair length is correlated with its diameter
Hair length and thickness are related, with thickness peaking at about a quarter of the hair's maximum length.
research Penetration Profile of Microspheres in Follicular Targeting of Terminal Hair Follicles
Microspheres about 1.5 micrometers in size can best penetrate hair follicles, potentially reaching important stem cells.
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 Quantitative trichoscopic analysis of hair density in people attending tertiary care hospital – A cross-sectional study
Hair density decreases with age, especially in the 60s.
research HAIR DISEASES
Most hair loss can be diagnosed with patient history and physical exam, and a few common types make up most cases.
research Human hair follicle: reservoir function and selective targeting
The human hair follicle can store topical compounds and be targeted for drug delivery with minimal side effects.
research A randomized double-blind placebo-controlled pilot study to assess the efficacy of a 24-week topical treatment by latanoprost 0.1% on hair growth and pigmentation in healthy volunteers with androgenetic alopecia
Latanoprost 0.1% may effectively treat hair loss.
research Examining the Safety and Efficacy of Low-Level Laser Therapy for Male and Female Pattern Hair Loss: A Review of the Literature
Low-level laser therapy safely and effectively improves hair growth and coverage for male and female pattern hair loss.
research Histology of the Human Hair Follicle
Understanding hair follicle structure is key for treating hair disorders and could help develop new treatments.
research Hair Follicle Miniaturization in a Woolly Hair Nevus
The boy with woolly hair nevus had thinner hair and abnormal hair follicles, which improved with treatment but worsened when treatment stopped.
research Lonely Hair Sign: Not Specific for Frontal Fibrosing Alopecia
Hair diameter diversity is a key sign for diagnosing and managing male pattern baldness.
research Hair Follicle Biology and Topical Minoxidil: Possible Mechanisms of Action
Minoxidil stimulates hair growth by increasing hair thickness and prolonging growth phase.
research A novel cosmetic approach to treat thinning hair
A new hair treatment with caffeine and other ingredients makes hair thicker and less likely to break.
