This study successfully developed a method to culture human hair follicle cells without a biological feeder layer, maintaining cell differentiation for a month.

This study reported that injecting monofilament threads into the scalp significantly improved hair count and hair mass index in women with female pattern hair loss, with most participants noticing substantial improvements in hair characteristics compared to a placebo.

This review updates on various methods for hair and scalp examination, encompassing non-invasive, semi-invasive, and invasive techniques, and reports no new results.

This article outlines a practical method for diagnosing and managing feline symmetrical alopecia but presents no new empirical findings.

This article presents modifications to the microfollicular hair transplant process, reporting innovations at each step to enhance results based on over 1000 cases at the authors' center.

This study established a simple, accurate, and precise HPLC method for determining the content and content uniformity of finasteride capsules.

This review critically examines Forensic DNA Phenotyping, highlighting high accuracy in predicting certain traits but also legal and ethical challenges, particularly around regulatory fragmentation and issues of genetic privacy.

This abstract introduces the concept of follicular units (FUs) in the human scalp but presents no new research findings.

In this study, a square pulse, low-fluence IPL device used at home significantly reduced terminal hair count by 87% six months post-treatment, with evidence of hair miniaturization similar to professional laser treatments.

In this study, researchers used advanced infrared microspectroscopy techniques to map the chemical composition of human hair, revealing new insights such as the presence of glycogen in the outer root sheath and the widespread distribution of calcium carboxylates in the hair cuticle.

This critique suggests that the prior iconodiagnosis of Vermeer's "Girl with a Pearl Earring" suffers from confirmation bias, arguing that cultural trends, rather than medical conditions, explain the artwork's features.

This study evaluated an in vitro inhalation method to assess the toxicological impacts of aerosols from heated hair products, revealing significant differences in cellular stress and IL-8 release among different test materials, which may help in developing safer products.

This study used single-cell RNA sequencing to characterize 19 distinct cell populations in sheep hair follicles, uncovering differentiation signatures and intercellular communication that may influence wool curvature and sheep breeding.

In this study, researchers developed a three-dimensional ultrastructural analysis tool using serial block-face scanning electron microscopy to reveal detailed nerve networks and muscle structures in human skin tissues, demonstrating the technique's potential to study structural changes in aging or disease.

This study developed a silk fibroin/poly(vinyl alcohol) microneedle loaded with α-aminoxyacetate and HfO₂ nanoparticles for vitiligo treatment, which protected against ROS damage and modulated immune responses, leading to improved melanogenesis and skin repigmentation.

This study found that laccase-assisted grafting of poly(tyrosine) onto wool materials improved shrinkage resistance and mechanical properties while causing minor decreases in crystallinity and thermal resistance, suggesting a potential "green" approach to enhance wool durability.

This small study reports that a 6-group geometric classification method is more reliable for classifying human hair curl, although a digital system could further reduce errors.

Using K2S2O8 as an oxidizing agent in a specific condition, we can make Finasteride with 96.3% yield and 99.6% purity. This method is also good for other compounds and is environmentally friendly.

This study concluded that combining vertical and transverse sections of scalp biopsy specimens improves diagnostic yield for certain hair disorders without increasing costs.

This study found that segmental single hair analysis produced ocfentanil concentration profiles similar to those from hair lock analysis, supporting its use in cases with limited samples.

This study found that facial threading decreased skin roughness and improved subjective assessments of skin smoothness and color after three sessions.

This study conclusively demonstrated that in Merino fetuses, secondary follicle initiation is completed several weeks before birth, with a peak 16 days prior and lower levels observed at and after birth.

This case study describes a 14-year-old girl with pili annulati who had fragile hair, which may be due to cavities within the hair shafts as seen in electron microscopic examinations.

This study found that treating hair with 1 M sodium hydroxide increases its self-friction coefficient, suggesting potential applications in forming fine frictional fibers for medical uses.

This exploratory pilot study reported that using a 2% Oleosome-FGF-2 fusion extract scalp serum twice daily for 84 days in women with telogen effluvium and brittle hair improved hair density, anagen/telogen ratio, hair shaft thickness, and scalp hydration compared to a placebo.

This study confirmed that an injectable implant known as RISUG-PH™, when administered via the vas deferens, successfully delivers the drug Finasteride to the prostate in male rats for up to 28 days, suggesting a potential localized alternative to oral delivery methods.

In this in vitro study, Yifa Compound Prescription was reported to enhance human hair follicle growth and increase VEGF mRNA expression compared to blank serum.

This study developed a new HPLC method for detecting prohibited substances like minoxidil and hydrocortisone in cosmetic products, achieving high sensitivity and successful application to real-world samples.

This study found that selective adhesion to type IV collagen successfully enriched human hair follicle stem cells based on distinct adhesion properties and marker expressions.

In this study, researchers found that the wash method can effectively differentiate between chronic telogen effluvium and early female androgenetic alopecia, potentially negating the need for scalp biopsy.
