270-300 / 1000+ resultsresearch Dynamic ultrastructural changes of the connective tissue sheath of human hair follicles during hair cycle
The connective tissue around hair follicles changes structure throughout the hair cycle.
research Asebia-2J (Scd1ab2J): A New Allele and a Model for Scarring Alopecia
The absence of functional sebaceous glands causes hair follicle destruction and scarring alopecia.
research Organ-Level Quorum Sensing Directs Regeneration in Hair Stem Cell Populations
Plucking some hairs can trigger nearby unplucked hairs to grow back more due to a collective response.
research Hypothalamic–Pituitary–Thyroid Axis Hormones Stimulate Mitochondrial Function and Biogenesis in Human Hair Follicles
HPT axis hormones boost mitochondrial function and growth in hair follicles, potentially aiding hair health.
research Natural Scalp Hair Regression in Preclinical Stages of Male Androgenetic Alopecia and Its Reversal by Finasteride
Finasteride reverses early hair loss and promotes growth.
research Scalp Itch: A Systematic Review
The document concludes that accurate diagnosis and treatment of scalp itch require differentiating between various conditions using a proposed five-step evaluation process.
research Quantitative analysis of the anatomical changes in the scalp and hair follicles in androgenetic alopecia using magnetic resonance imaging
MRI reveals thinner scalps and smaller hair follicles in people with androgenetic alopecia.
research Common Allergens Identified Based on Patch Test Results in Patients with Suspected Contact Dermatitis of the Scalp
Nickel, cobalt, balsam of Peru, fragrance mix, carba mix, and propylene glycol are common allergens causing scalp contact dermatitis.
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 Distinguishing Lipedematous Scalp, Lipedematous Alopecia, and Diffuse Alopecia Areata
The conclusion is that it's important to tell apart alopecia areata from lipedematous alopecia for proper treatment, as alopecia areata can be reversed.
research Contrast enhanced phototrichogram pinpoints scalp hair changes in androgen sensitive areas of male androgenetic alopecia
CE-PTG detects early hair follicle issues in balding areas, helping measure male hair loss.
research Exogen hair characterization in human scalp
The conclusion is that exogen is a unique hair cycle phase and the new sampling method specifically targets this stage, which may help in future hair loss research.
research Gender differences in scalp hair growth rates are maintained but reduced in pattern hair loss compared to controls
Women's hair grows faster and thicker than men's, but hair growth slows for both genders with pattern hair loss.
research Pigmented Hair-Thickening Fibers: A Camouflage Technique for Alopecia in Patients with Epidermolysis Bullosa
Colored hair-thickening fibers can help hide hair loss in some people with Epidermolysis Bullosa but may cause scalp irritation.
research Follicular Map: A Novel Approach to Quantitative Trichoscopy
The new Follicular Map method could help assess hair treatment effectiveness but has some limitations.
research Investigation of hair shaft in seborrheic dermatitis using atomic force microscopy
Hair from people with seborrheic dermatitis is thicker scaled, more damaged, and thinner than healthy hair, and atomic force microscopy can help monitor the condition.
research Sonographic comparison of subcutaneous fat layer thickness in the scalp area in patients with androgenetic alopecia compared to healthy individuals: Cross‐sectional
Patients with androgenetic alopecia have thinner subcutaneous fat layers in their frontal scalp compared to healthy individuals.
research High‐frequency ultrasonography of the scalp: A comparison between androgenetic alopecia and healthy volunteers
High-frequency ultrasound can effectively visualize and assess hair loss.
research Leveraging deep neural networks to uncover unprecedented levels of precision in the diagnosis of hair and scalp disorders
A new AI model diagnoses hair and scalp disorders with 92% accuracy, better than previous models.
research Investigation of aging effects in human hair using atomic force microscopy
Aging makes hair thinner and rougher, with less clear edges.
research Tinea Capitis Presenting as Diffuse Hair Loss and Significance of Trichoscopy: Four Case Reports
Trichoscopy is useful for correctly diagnosing tinea capitis in adults with unexplained hair loss.

research Human Scalp Hair Follicles Are Both a Target and a Source of Prolactin, which Serves as an Autocrine and/or Paracrine Promoter of Apoptosis-Driven Hair Follicle Regression
Prolactin contributes to hair loss by promoting hair follicle shrinkage and cell death.
research Role of Trichoscopy in Children's Scalp and Hair Disorders
Trichoscopy is good for diagnosing and monitoring hair and scalp problems in children but needs more research for certain conditions.
