This study found that glycolytic metabolism and lactate production are crucial for hair follicle stem cell activation, and manipulating these processes can stimulate the hair cycle.

This study used molecular dynamics simulations to illustrate the complex molecular behavior of the hair surface F-layer, highlighting how fatty acids interact with 18-MEA under different conditions.

This study found that Par3 plays a crucial role in maintaining epidermal homeostasis by regulating Rho/actomyosin contractility and ensuring mitotic accuracy, with potential implications for other self-renewing epithelia.

This study discusses that permanent hair straightening can be achieved at neutral or acidic pH conditions, with varying effects on cystine and lanthionine levels, by inducing supercontraction of the hair fiber.

In this study, a water-soluble nail strengthener containing Pistacia lentiscus and hyaluronic acid significantly improved the appearance and firmness of brittle nails in both in vitro and clinical settings.

PMS nanoparticles improve damaged hair by protecting and restoring its surface and color.

This study found that hair membrane fluidity is low in the cuticle but high in the cortex and medulla, with treatments like ionic surfactants and oleic acid increasing fluidity in hydrated hair; however, dehydration significantly reduces fluidity throughout the hair.

In this study, Leonuri Herba alkaloids significantly reduced prostate hyperplasia indicators and improved urinary parameters in hormone-induced model rats.

In this randomized controlled trial, oral intake of the probiotic Latilactobacillus curvatus LB-P9 significantly improved hair luster, elasticity, and participant satisfaction in individuals with mild to moderate hair damage compared to placebo, without significant adverse effects reported.

This study found that chemical treatments such as hair bleach and UV radiation significantly reduced the amount of 18-methyleicosanoic acid on the outer surface of human hair.

This study found that a liposome containing butterfly pea flower extract and clove oil was stable and, when used by 15 volunteers over 60 days, enhanced eyebrow thickness and darkness without causing irritation.

This study evaluated the effectiveness of three formulated hair conditioners—Herbal, Synthetic, and Ayurvedic—using organoleptic and physicochemical tests like pH, Dirt Dispersion, and Stability, with the main aim to develop a product that meets user compliance and desired hair care effects.

This study concluded that a hair tonic combining aloe vera and celery extracts can be formulated, with formula 1 meeting the stability requirements best over a month.

This study identified a missense mutation in the rat Desmoglein 4 gene, causing abnormal hair shaft development in lanceolate hair mutant rats by disrupting a critical calcium binding site.

This study found that the topical application of DA-OTC-002, a combination of synephrine and tyramine hydrochloride, significantly reduced immediate hair shedding in women by 62.5% compared to a placebo, without any observed adverse effects.

A specific mutation in PA-PLA1α causes abnormal hair growth.

This study suggests that linalool, a common allergen in personal care products, may contribute to frontal fibrosing alopecia pathogenesis by triggering immune responses and depleting hair follicle stem cells, especially in sensitized individuals.

CTP-543 significantly improved eyebrow and eyelash regrowth and patient satisfaction in adults with alopecia areata.

This study concluded that the formulated polyherbal shampoo using natural ingredients is safe, stable, and effective for hair care, showing good cleansing, conditioning, and nourishment properties as a natural alternative to synthetic shampoos.

A specific gene mutation causes sparse, brittle hair in a family.

This study found that Soxhlet extraction is more effective at removing the toxin mimosine from Leucaena leucocephala, and mimosine shows promise as a biodiesel additive due to its antioxidative properties.

In this study, Tithonia diversifolia extract was found to improve certain digestive parameters in crossbred sheep but did not enhance growth performance, as the improvements in digestion did not translate into increased body weight or feed conversion.

This study suggests that combining Silybum marianum extract, Manganese PCA, and Lespedeza capitata extract may help improve hair growth and anchorage by targeting specific signaling pathways in human dermal papilla cells.

In this study, Nε-(carboxymethyl) lysine was found to weaken hair follicle morphogenesis and inhibit essential cell activities in a model simulating accumulated glycation.

In this study, inducible whole-body Acly-knockout mice revealed that ACLY is essential for skin homeostasis, as its deficiency led to increased sebum production and skin abnormalities, indicating a vital role for cytosolic acetyl-CoA synthesis in preserving skin barrier integrity and systemic lipid regulation.

In this study, ultradeformable liposomes containing Tween 20 or terpenes increased phospholipid bilayer fluidity and enhanced skin penetration of sodium fluorescein, with terpenes improving hair follicle penetration.

Polyethylene alanine caused hair loss in young lab animals but not in adults, with hair regrowth occurring within 20 days.

In this study, PDLLA treatment in middle-aged mice was observed to enhance hair growth by increasing macrophage M2 polarization and hair follicle stem cell proliferation, potentially rejuvenating the skin's microenvironment and offering a novel approach for age-related hair loss.
