research Telogen Effluvium-Reply
Both parties agree that cell death is important in the hair cycle, but they have different views on the role of the catagen phase and hair shedding.
research 330 A novel cosmetic anti-hair loss approach: An extract of Leontopodium alpinum inhibits catagen development
Edelweiss extract may help prevent hair loss and increase hair density.
research Integrated analysis of lncRNAs and mRNAs by RNA-Seq in secondary hair follicle development and cycling (anagen, catagen and telogen) of Jiangnan cashmere goat (Capra hircus)
lncRNAs play a key role in hair follicle development, affecting cashmere quality and yield.
research Dopamine is a novel, direct inducer of catagen in human scalp hair folliclesin vitro
Dopamine stops hair growth and pigment production in human scalp hair follicles.
research The up‐regulation of 14‐3‐3 proteins in Smad4 deficient epidermis and hair follicles at catagen
Increased 14-3-3 proteins may block hair cycle regression, causing hair loss.
research Hair Cycle Control by Estrogens: Catagen Induction via Estrogen Receptor (ER)-α Is Checked by ERβ Signaling
Estrogen receptors affect hair growth, with ER beta slowing down the hair cycle changes caused by ER alpha.
research Roxithromycin antagonizes catagen induction in murine and human hair follicles: implication of topical roxithromycin as hair restoration reagent
Roxithromycin, an antibiotic, can increase hair growth and might be used as a treatment for hair loss.
research Acute and Chronic Telogen Effluvium
Hair shedding that lasts over 6 months may need a closer look, but often just reassurance is enough.
research Performing a Nonsurgical Hair Restoration Consultation
Practitioners should understand hair growth and loss causes to effectively consult on nonsurgical hair restoration.
research A Meeting of Two Chronobiological Systems: Circadian Proteins Period1 and BMAL1 Modulate the Human Hair Cycle Clock
BMAL1 and Period1 genes can influence human hair growth.
research From Telogen to Exogen: Mechanisms Underlying Formation and Subsequent Loss of the Hair Club Fiber
Hair shedding is an active process that could be targeted to treat hair loss.
research Immunolocalization of telomerases in human hairs identifies proliferating cells in the bulb matrix and outer root sheath
Telomerase-positive cells are mainly in the bulb matrix and outer root sheath of hair follicles.
research Integrative and Mechanistic Approach to the Hair Growth Cycle and Hair Loss
A holistic approach is needed to effectively address hair loss by understanding and influencing the hair growth cycle.
research Intrinsic ROS Drive Hair Follicle Cycle Progression by Modulating DNA Damage and Repair and Subsequently Hair Follicle Apoptosis and Macrophage Polarization
Reactive oxygen species (ROS) influence hair growth by causing DNA damage, cell death, and changes in immune cells.
research Expression Pattern of Cyclooxygenase-2 in Normal Rat Epidermis and Pilosebaceous Unit during Hair Cycle
COX-2 levels change during the hair cycle and affect skin and hair growth.
research Hair Follicle Morphogenesis During Embryogenesis, Neogenesis, and Organogenesis
The document concludes that understanding adult stem cells and their environments can help improve skin regeneration in the future.
research Controlling Hair Loss by Regulating Apoptosis in Hair Follicles: A Comprehensive Overview
Regulating cell death in hair follicles can help prevent hair loss and promote hair growth.
research EGFR : stopping stathmin to start the cycle
EGFR helps hair follicles transition properly by controlling Stathmin levels.
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 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 An Updated in the Management of Alopecia Areata
New treatments for alopecia areata show promise, but more research is needed to confirm their effectiveness.
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 A simple immunofluorescence technique for simultaneous visualization of mast cells and nerve fibers reveals selectivity and hair cycle - dependent changes in mast cell - nerve fiber contacts in murine skin
Mast cell and nerve fiber interactions in mouse skin change with the hair cycle.
research Shh Gene Regulates the Proliferation and Apoptosis of Dermal Papilla Cells to Affect Its Differential Expression in Secondary Hair Follicle Growth Cycle of Cashmere Goats
The Shh gene controls cell growth and death in cashmere goat hair follicles, affecting hair growth.
