Inositol and arginine solutions improve hair follicle health and turnover.
research Action of Thioglycolic Acid and L-Cysteine to Disulfide Cross-Links in Hair Fibers during Permanent Waving Treatment
Thioglycolic acid and L-cysteine change hair structure differently during perms, affecting hair strength and curling efficiency.
research Pattern of Cutaneous Manifestations in Systemic Lupus Erythematosus: A Cross-Sectional Hospital-Based Study
Skin issues are common in lupus patients, highlighting the need for thorough skin checks.
research Frequency, severity and related factors of androgenetic alopecia in dermatology outpatient clinic: hospital-based cross-sectional study in Turkey
AGA more common in men, increases with age, linked to family history, hypertension, dyslipidemia, and smoking.
research Self-esteem and body image satisfaction in women with PCOS in the Middle East: Cross-sectional social media study
Women with PCOS have lower self-esteem and body image satisfaction.
research The unseen Impact of an observable disease: Association of dihydrotestosterone levels and psychosocial impact in androgenetic alopecia: An analytical cross-sectional study
Androgenetic alopecia in males is linked to significant psychological distress, highlighting the need for both mental and dermatological care.
research Assessment of Multidimensional Health Care Parameters Among Adults in Japan for Developing a Virtual Human Generative Model: Protocol for a Cross-sectional Study (Preprint)

research Measuring changes in chemistry, composition, and molecular structure within hair fibers by infrared and Raman spectroscopic imaging
Infrared and Raman imaging can non-destructively analyze hair structure and help diagnose hair conditions.
research Effect of equilibrium pH on the structure and properties of bleach‐damaged human hair fibers
Hair's structure and properties change with pH; acidic pH maintains strength and less swelling, while alkaline pH increases water content and swelling.
research Study on Hair Distribution in Healthy Males for Hair Restoration Design
About 21.3% of young, healthy Chinese men experience hair loss. Hairlines are mostly linear or have a central protrusion. Hair is densest on the top and back of the head, and hair follicles usually have 1 or 2 hairs. This information can help in designing hair restoration procedures.
research Mechanical forces across compartments coordinate cell shape and fate transitions to generate tissue architecture
Mechanical forces are crucial for shaping cells and forming tissues during development.
research Keratin network modifications lead to the mechanical stiffening of the hair follicle fiber
Changes in keratin make hair follicles stiffer.
research 862 Defining the molecular signature of the hair follicle dermal sheath and its functional requirement for hair cycle progression during catagen
The hair follicle dermal sheath is essential for hair shedding and needs to communicate with the outer root sheath for normal hair growth cycles.
research Hair anatomy for the clinician
Understanding hair follicle anatomy helps diagnose hair disorders.
research Androgenic Alopecia: Cross-Talk Between Cell Signal Transduction Pathways
Hair loss in Androgenetic alopecia (AGA) is due to altered cell sensitivity to hormones, not increased hormone levels. Hair growth periods shorten over time, causing hair to become thinner and shorter. This is linked to miscommunication between cell pathways in hair follicles. There's also a change in gene expression related to blood vessels and cell growth in balding hair follicles. The exact molecular causes of AGA are still unclear.
research Embryology, Histology, and Physiology of the Hair Follicle
The document explains how hair follicles develop, their structure, and how they grow.
research Perifollicular vascularization: Cocultures and tricultures approaches to study the cross-talk between microvascular endothelial cells, follicle papilla cells and keratinocytes
Hair papilla cells are crucial for blood vessel development in hair follicles, affecting hair growth and loss.
research Dermatopathology of Common Hair Problems
Examining scalp biopsies in different ways helps better diagnose hair loss types.
research Ethnic Considerations in Hair Restoration Surgery
Different ethnic hair traits must be considered for successful hair restoration surgery to achieve natural-looking results.
research Morphological changes of the hair roots in alopecia areata: A scanning electron microscopic study
Scanning electron microscopy revealed four distinct hair root shapes in alopecia areata, suggesting a less invasive diagnostic method.
research ARHGEF3 Regulates Hair Follicle Morphogenesis
