This study found that caffeine and flufenamic acid penetrated porcine skin more effectively through hair follicles, while the importance of the follicular pathway varied for other substances tested.

This study proposed a new standardized in vitro framework using human hair tresses to evaluate cosmetic hair product performance and found significant improvements in hair breakage, tensile strength, shine, volume, and frizz control compared to a control group without such changes.

This study found that pomade containing 12% ethanol extract of Momordica charantia L. leaves promoted hair growth more effectively in male white rats compared to lower concentrations and a control.

This study found that an aqueous extract of Phyllanthus emblica, primarily containing gallic acid, can activate hair growth gene expression and is effectively delivered to hair follicles using transfersomes.

This article discusses the use of full-time and per diem staff in hair restoration practices to optimize outcomes but does not report any new clinical results.

This source highlights the utility of cationic polymers in haircare products for protecting against hair damage from chemical treatments and grooming, and describes how microfluorometry can measure polymer deposition and penetration on hair fibers.

This study found that hydrophobic amino acids from egg white hydrolyzed protein and L-phenylalanine effectively penetrate deep into the human hair fiber, increasing specific contents in both virgin and bleached hair.

In this study, particles similar in size to keratin cells were surprisingly found to penetrate more efficiently into hair follicles due to a possible pumping effect from moving hairs.

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, researchers developed an innovative training model using oranges to practice designing the scalp's parietal whorl for hair transplantation. They reported that a density of 40-50 follicular units per cm² achieved better results, aiding surgeons in improving their technique.

In this study, researchers developed a simplified and reliable method to prepare human hair shaft samples, achieving over 75% protein extraction efficiency and improved keratin sequence coverage, with the approach showing high reproducibility across different labs and operators.

This study found that finasteride-loaded microemulsions using poloxamer 124 significantly enhanced skin penetration of the drug compared to a standard solution, primarily through targeting hair follicles via the transfollicular pathway, with intercluster, intercellular, and transcellular pathways contributing less.

This study introduces a new test using a pendulum device to assess the bending stiffness of hair fibers, which can evaluate the effects of different hair treatments.

This study found that applying hair conditioner during a permanent wave process in the middle rather than early or late improves tensile strength, hydration, and maintains healthier hair cuticle structure.

This study reported that the n-butanol fraction of Perilla frutescens extract, particularly rosmarinic acid, showed potential for hair regrowth and anti-androgenic activity in male mice, suggesting it as a possible treatment for androgenetic alopecia.

This study found that Puerariae Radix ethanol extracts increased the proliferation of human hair dermal papilla cells via ERK and Akt phosphorylation, suggesting potential benefits for alopecia treatment.

This letter to the editor reports no new results but discusses the effect of hairpieces on the perceived quality of life in female pattern hair loss patients.

This article discusses advancements in hair restoration surgery techniques and does not provide new research findings.

In this experimental study on rabbits, the authors concluded that a pomade containing 10% meniran leaf extract was an effective hair growth stimulant and could compete with a positive control, fulfilling the required pomade characteristics.

Ethosomes improve finasteride delivery through skin for hair loss treatment.

In this study, the authors found that finasteride treatment for male pattern alopecia showed increasing effectiveness over 24 months, with the most significant results observed after 12 months.

This study investigated non-laser methods for removing permanent makeup using plant extracts, testing their decolorization effects on mice through tattooing and electroporation techniques.

This study found that keratin-based particles were able to recover and enhance the mechanical properties and thermal stability of virgin and overbleached Asian hair, improving its strength and smoothness by around 40%, and demonstrated safety in human skin keratinocytes.

This study found that penetration enhancer-containing vesicles significantly improved minoxidil delivery to the skin compared to traditional liposomes and penetration enhancer-containing ethanolic solutions, with deformability linked to enhanced deposition.

This study describes an adaptive hair extension method designed to improve comfort, durability, and aesthetics, based on analysis of hypothetical client profiles and their biomechanical tolerance.

In this study, the researchers found that a manual micrometer caliper is a reliable tool for planning hair transplant surgery and accurately measures the short axis of the hair shaft.

This study found that FDA-cleared devices for preparing platelet-rich plasma showed inconsistent product quality, with variable platelet counts and inadequate quality control performance, suggesting clinical improvement may not rely on platelet concentration.

In this laboratory study on rabbits, the researchers observed that both FET and FHE fractions improved hair length and weight, but minoxidil still led to better results, highlighting the comparative effects of different treatments on hair growth over 28 days.

PEVs effectively deliver minoxidil through skin.

This clinical trial found that using a 45-degree angled implanter with the bevel facing the skin in FUE hair transplantation significantly reduced insertion resistance, graft popping, and bleeding, while improving efficiency and graft alignment compared to conventional methods.
