Research
660-690 / 1000+ resultsresearch Mice lacking the epidermal retinol dehydrogenases SDR16C5 and SDR16C6 display accelerated hair growth and enlarged meibomian glands
Mice without certain skin enzymes have faster hair growth and bigger eye glands.
research Miniflap Hair Restoration
Dr. George A. Farber recommends using follicular unit transplantation for hair restoration because it gives a more natural look and has fewer problems compared to the older miniflap technique.
research Simultaneous Target-Mediated Drug Disposition-Pharmacodynamic (TMDD-PD) Modeling of Finasteride and Dutasteride: Impact of Target Binding and Turnover on Non-linear Pharmacokinetics
Finasteride and dutasteride's effects are mainly due to target binding saturation and slow enzyme turnover.
research Stability of Hairline Lowering Using Small Footprint Soft Tissue Anchoring Devices
The Endotine Forehead-mini effectively lowers the hairline with lasting results and minimal risks.
research Hair shaft miniaturization causes stem cell depletion through mechanosensory signals mediated by a Piezo1-calcium-TNF-α axis
Hair thinning causes stem cell loss through a process involving Piezo1, calcium, and TNF-α.
research Autosomal recessive monilethrix: Novel variants of the DSG4 gene in three Chinese families
New gene variants linked to a rare inherited hair loss disorder were found in three Chinese families.
research LncRNA MSTRG.14227.1 regulates the morphogenesis of secondary hair follicles in Inner Mongolia cashmere goats via targeting ADAMTS3 by sponging chi-miR-433
LncRNA MSTRG.14227.1 hinders hair follicle development in cashmere goats, affecting cashmere quality.
research Effects of TNF-${\alpha}$ and Minoxidil on Human Hair Growth in Vitro
TNF-${\alpha}$ slows hair growth, and minoxidil doesn't help.
research The Thinning Top: Why Old People Have Less Hair
Old people have less hair because their hair follicles don't regenerate as well, not because of fewer stem cells, and a protein called follistatin might help reactivate hair growth.
research Micrografting in Extensive Quantities Please Note: In 1995 we began using Follicular Unit Transplantation for all hair restoration procedures performed at NHI. Minigrafting/micrografting techniques were discontinued at this time. This article should be read in that context.
Since 1995, we only use Follicular Unit Transplantation for hair restoration and stopped using minigrafting/micrografting techniques.
research Follicle-innervating Aδ-low threshold mechanoreceptors organize through a population-dependent mechanism
Mouse touch-sensitive nerve cells adjust their connections based on competition with other similar cells.
research Effects of TGFBR1 on Proliferation of Dermal Papilla Cells in Fine-Wool Sheep
TGFBR1 slows down cell growth in fine-wool sheep hair follicles.
research The Ludwig pattern of androgenetic alopecia is due to a hierarchy of androgen sensitivity within follicular units that leads to selective miniaturization and a reduction in the number of terminal hairs per follicular unit
Ludwig pattern hair loss results from varying androgen sensitivity, causing fewer thick hairs and more thin hairs.
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 Different effects of phospholipase Dζ2 and non‐specific phospholipase C4 on lipid remodeling and root hair growth in Arabidopsis response to phosphate deficiency
PLDζ2 and NPC4 have different roles in lipid changes and root hair growth in Arabidopsis under low phosphate, with PLDζ2 reducing root hair growth and NPC4 promoting it.
research Cardiac Outflow tract septation defects in a DiGeorge syndrome model respond to Minoxidil treatment.
Minoxidil treatment improves heart defects in a DiGeorge syndrome model.
research Extended theory of selective photothermolysis: A new recipe for hair cooking?
Permanent hair removal is hard, but using longer laser pulses at lower power might improve results.
research Progressive Alopecia Reveals Decreasing Stem Cell Activation Probability during Aging of Mice with Epidermal Deletion of DNA Methyltransferase 1
Mice lacking a key DNA methylation enzyme in skin cells have a lower chance of activating stem cells necessary for hair growth, leading to progressive hair loss.
research Progressive Alopecia Reveals Decreasing Stem Cell Activation Probability during Aging of Mice with Epidermal Deletion of DNA Methyltransferase 1
Aging reduces stem cell activation, leading to hair loss in mice lacking a specific enzyme.
research Increased dipicolinic acid production with an enhanced spoVF operon in Bacillus subtilis and medium optimization
Genetically modifying a bacteria and changing its growth conditions significantly increased the production of a chemical called dipicolinic acid.
research Tyrosinase Depletion Prevents the Maturation of Melanosomes in the Mouse Hair Follicle
Reducing Tyrosinase prevents mature color pigment cells from forming in mouse hair.
research Inducible deletion of epidermal Dicer and Drosha reveals multiple functions for miRNAs in postnatal skin
Drosha and Dicer are essential for hair follicle health and preventing DNA damage in skin cells.
research Disposable Instrumentation—The Future of Hair Restoration Surgery
Disposable tools could make hair restoration surgery safer and more efficient.
research Studies of the availability of soil phosphorus (P) and potassium (K) in organic farming systems, and of plant adaptations to low P- and K-availability
Organic farms need to supplement phosphorus and potassium to maintain soil health and crop yields.
research Miniaturized hairs maintain contact with the arrector pili muscle in alopecia areata but not in androgenetic alopecia: A model for reversible miniaturization and potential for hair regrowth
Miniaturized hairs stay connected to muscle in alopecia areata, allowing possible regrowth, but not in androgenetic alopecia.
research Reduction in wool follicles prior to birth in Merino sheep
Merino sheep have fewer wool follicles at birth than before birth.
research The Noggin null mouse phenotype is strain dependent and haploinsufficiency leads to skeletal defects
Noggin gene inactivation causes skeletal defects in mice, varying by genetic background.
