research Hair physiology and its disorders
Different hair growth problems are caused by genetic issues or changes in hair growth cycles, and new treatments are being developed.
research Gata6 promotes hair follicle progenitor cell renewal by genome maintenance during proliferation
Gata6 is important for protecting hair growth cells from DNA damage and keeping normal hair growth.
research Expression patterns of the glial cell line–derived neurotrophic factor, neurturin, their cognate receptors GFRα-1, GFRα-2, and a common signal transduction element c-Ret in the human skin hair follicles
Certain proteins and their receptors are more active during the growth phase of human hair and could be targeted to treat hair disorders.
research Catagen in the hairless house mouse
Hairless mice have longer hair follicles and abnormal structures during the catagen phase.
research The Biology of Hair Growth
Hair growth is influenced by hormones and goes through different phases; androgens can both promote and inhibit hair growth depending on the body area.
research A comprehensive review of biochemical factors in herbs and their constituent compounds in experimental studies on alopecia
Herbs might help with hair loss, but more research is needed to confirm their safety and effectiveness.
research Cashmere growth control in Liaoning cashmere goat by ovarian carcinoma immunoreactive antigen-like protein 2 and decorin genes
OCIAD2 and DCN genes affect hair growth in goats by having opposite effects on a growth signaling pathway and inhibiting each other.
research Ginsenoside Re prevents 3-methyladenine-induced catagen phase acceleration by regulating Wnt/β-catenin signaling in human dermal papilla cells
Ginsenoside Re from Panax ginseng may prevent hair loss by maintaining autophagy and Wnt signaling in hair cells.
research Utility of Horizontal Sections of Scalp Biopsies in Differentiating between Androgenetic Alopecia and Alopecia Areata
Scalp biopsies help tell apart androgenetic alopecia and alopecia areata.
research ′Swiss cheese′ appearance of dilated follicular infundibula in trichotillomania
The 'Swiss cheese' pattern in scalp biopsies can indicate trichotillomania, not just alopecia areata.
research 593 Low versus high fluence light-induced hair removal: How hair follicle ex vivo studies translate into clinical results
Higher fluence in hair removal damages hair follicles more, while lower fluence mimics natural hair regression, with long-term IPL treatments effectively reducing hair.
research A patient with diffuse hair loss
The patient's hair loss is most likely due to diffuse alopecia areata.
research Hair anatomy for the clinician
Understanding hair follicle anatomy helps diagnose hair disorders.
research Do Hair Bulb Melanocytes Undergo Apotosis During Hair Follicle Regression (Catagen)?
Hair follicle melanocytes die during hair regression.
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 Neurogenic Inflammation in Stress-Induced Termination of Murine Hair Growth Is Promoted by Nerve Growth Factor
Stress increases a factor in mice that leads to hair loss, and blocking this factor may prevent it.
research A Guide to Assessing Damage Response Pathways of the Hair Follicle: Lessons From Cyclophosphamide-Induced Alopecia in Mice
The document concludes that assessing hair follicle damage due to cyclophosphamide in mice involves analyzing structural changes and suggests a scoring system for standardized evaluation.
research Development and progression of alopecia in the vitamin D receptor null mouse
Mice without the vitamin D receptor gene lose hair due to disrupted hair follicle cycles.
research Mast cell deficient and neurokinin-1 receptor knockout mice are protected from stress-induced hair growth inhibition
Certain mice without specific receptors or mast cells don't lose hair from stress.
research Bone Morphogenetic Protein Signaling Regulates Postnatal Hair Follicle Differentiation and Cycling
Blocking BMP signaling causes hair loss and disrupts hair growth cycles.
research Type II Epithelial Keratin 6hf (K6hf) Is Expressed in the Companion Layer, Matrix, and Medulla in Anagen-Stage Hair Follicles
K6hf is found in specific parts of hair follicles, nails, and tongue, and is linked to hair growth and structure.
research Overexpression of Bcl-2 Protects from Ultraviolet B-Induced Apoptosis but Promotes Hair Follicle Regression and Chemotherapy-Induced Alopecia
Bcl-2 overexpression protects against UVB damage but worsens hair loss from chemotherapy.
research Involvement of the Edar Signaling in the Control of Hair Follicle Involution (Catagen)
Edar signaling is crucial for controlling hair growth and regression.
research Canine noninflammatory alopecia: a comprehensive evaluation of common and distinguishing histological characteristics
Different types of dog hair loss are linked to problems starting the hair growth phase and early hair cycle ending.
research Igf1r signalling acts on the anagen‐to‐catagen transition in the hair cycle
Igf1r helps regulate hair growth cycles.
research Alopecia areata in a rhesus monkey (Macaca mulatta)
The monkey's hair loss was due to an autoimmune disease, not genetics.
research Dermoscopic Findings in Radiation-Induced Alopecia after Angioembolization
Radiation-induced alopecia after angioembolization usually heals on its own and can look like other hair loss types, but patient history helps prevent misdiagnosis.
research Construction of transcriptome atlas of white yak hair follicle during anagen and catagen using single-cell RNA sequencing
The research improved understanding of yak hair growth to help use yak wool better.
research Can an in vitro hair drug model be developed using dermal papilla cells alone?
Dermal papilla microtissues could be useful for initial hair growth drug testing.
