research Sensitive Quantitative In Vivo Assay for Evaluating the Effects of Biomolecules on Hair Growth and Coloring Using Direct Microinjections into Mouse Whisker Follicles
The new "whisker follicle microinjection assay" can test how different biomolecules affect hair growth and color.
research [Analysis of steroids and binding proteins in the blood of women with androgenetic alopecia].
Women with androgenetic alopecia have normal levels of most blood steroids and binding proteins, but higher dehydroepiandrosterone. Some also have low "sex hormone-binding globulin" and "corticosteroide-binding globulin" capacity, and high "free androgen index" and "free cortisol index". Diane treatment can normalize these levels and improve hair conditions.
research Hair cortisol concentrations in mental disorders: A systematic review
People with depression often have higher hair cortisol levels, while those with PTSD tend to have lower levels, but more research is needed to understand this fully.
research Hirsutism: Evaluation and treatment
Excessive hair growth can be assessed by history, exam, and blood tests, and treated with medication like dexamethasone, birth control pills, and spironolactone.
research Clinical and dermoscopic profile of female pattern hair loss
Dermoscopes help tell FPHL apart from other hair loss types and can detect it early by identifying specific patterns.
research Correlation of vitamin D and vitamin D receptor expression in patients with alopecia areata: a clinical paradigm
People with alopecia areata often have lower vitamin D levels, which are linked to more severe and longer-lasting hair loss, but vitamin D receptor levels in the skin don't show the same pattern and don't predict treatment success.
research Correction to “Divergent progression pathways in male androgenetic alopecia and female pattern hair loss: Trichoscopic perspectives”
The document corrects errors in a table about hair loss in women.
research 716A study of clinical and trichoscopic evaluation of diffuse hair loss in adult females
The study concluded that examining the scalp with a special magnifying device helps diagnose the cause of widespread hair loss in adult women.
research Three-Dimensional Histological Structures of the Human Dermis
3D images of skin show collagen is evenly spread, but elastic fibers are fewer near hair follicles.
research A simple assay for the study of human hair follicle damage induced by ionizing irradiation
Ionizing radiation damages human hair follicles by stopping cell growth, causing cell death, disrupting color, and increasing stress and damage markers.
research Distribution of Epidermal Growth Factor Receptors in Rat Tissues During Embryonic Skin Development, Hair Formation, and the Adult Hair Growth Cycle
research Establishment of SV40T-transformed human dermal papilla cells and identification of dihydrotestosterone-regulated genes by cDNA microarray
Researchers created a cell line to study hair growth and found specific genes affected by dihydrotestosterone.
research A New Technique for Quantitative Analysis of Hair Loss in Mice Using Grayscale Analysis
Researchers developed a new, precise method to measure hair loss in mice using image analysis.
research Quality of Life with Alopecia Areata versus Androgenetic Alopecia Assessed Using Hair Specific Skindex-29
Alopecia areata and androgenetic alopecia affect quality of life similarly.
research Evaluation of hair humidity resistance/moisturization from hair elasticity.
Polyquaternium-70 shampoo is best for reducing frizz.
research Hair analysis in health assessment
Hair mineral analysis might help diagnose diseases early, but standard methods are needed.
research Distinguishing Androgenetic Alopecia From Chronic Telogen Effluvium When Associated in the Same Patient
Shorter, thinner hairs indicate AGA, while longer, thicker hairs suggest CTE; counting and measuring shed hairs helps diagnose hair loss type.
research Topical finasteride: A potential therapeutic option for hidradenitis suppurativa
Topical finasteride may help improve hidradenitis suppurativa symptoms.
research Patient prioritisation of items to develop the Patient‐Reported Impact of Dermatological Diseases measure: A global Delphi study
The study created a 27-item measure to assess the impact of skin diseases.
research New frontiers in human hair follicle (neuro‐)endocrinology
Human scalp hair follicles can produce and respond to several hormones, affecting hair growth and pigmentation.
research Evaluation of the relationship of digital phototrichogram findings of patients with diffuse hair loss with blood TSH, ferritin and vitamin B12 levels
Low ferritin levels are linked to increased hair loss; no link found between vitamin B12, TSH levels, and hair loss.
research Hard X-ray Microscopic Images of the Human Hair
High-resolution x-ray images showed three main structures in human hair: medulla, cortex, and cuticle.
research Hirsutography: Photographic measurement of linear hair growth in hirsute women during comparison of anti-androgen treatments
The photographic method accurately measures hair growth and both treatments effectively reduced hair growth in hirsute women.
research 863 Molecular basis of hair follicle donor dominance in androgenetic alopecia and sexual dimorphism of the skin
Hair loss patterns differ between males and females due to 5 master regulators and JAK-STAT signaling affects hair growth.
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 Mechanism of action of androgen in hair follicles
Testosterone affects hair follicles differently across body sites, with beard hair follicles showing more activity of a specific enzyme and presence of androgen receptors compared to scalp hair.
research Sequential Hair Shaft as an Indicator of Prior Mineralization in the Alaskan Moose2
Moose hair can track past mineral levels, except zinc.
research Complete responses and SALT zero scores in alopecia areata: not the same
Significant hair regrowth doesn't always mean complete hair recovery in alopecia areata.
research Fast and Noninvasive Hair Test for Preliminary Diagnosis of Mood Disorders
A hair test shows promise for early mood disorder diagnosis.
