This study used phase contrast hard x-ray microscopy to capture detailed images of healthy human hair, revealing distinct structures such as the medulla, cortex, and cuticular layer.

This study found that combining optical clearing methods with light-sheet fluorescence microscopy allows detailed 3D visualization of normal and pathological human skin biopsies, revealing differences in epidermal thickness and volume.

In this study, the researchers observed that antiandrogen treatment with Cyproterone acetate led to atrophy of pilo-sebaceous units and may activate Langerhans cells, contributing to local inflammation.

This study observed distinct changes in the ultrastructure of Hexi cashmere goat hair follicles throughout the year, highlighting stages with specific cellular and structural characteristics.

This study observed that mink dermal collagen fibrils undergo structural changes during the hair cycle, with increased fiber thickness and bundle density as minks grow.

The hair follicle structure is more complex than thought, with new findings on protein formation.

This study found that keratin-associated proteins form part of the developing exocuticle and a-layer in hair fiber cuticle cells, while cornified envelope proteins were absent.

This review discusses the role of scalp imaging techniques in trichology for researching drug delivery and toxicology, without presenting new clinical results.

This study observed that calcium hydroxylapatite can be successfully incorporated and retained in the dermis for at least six weeks after fractional laser treatment, with new collagen forming around it.

This review discusses various topics from the 62nd Annual Montagna Symposium on the Biology of Skin, focusing on the diverse effects of light on skin biology, and reports no new clinical results.

This study found that an oil-in-water microemulsion of curcumin penetrated deeper into the human stratum corneum and hair follicles compared to an amphiphilic cream.

This article reviews various diagnostic tools for hair disorders, describing methods ranging from invasive to noninvasive, but reports no new research findings or clinical results.

This study found that a curcumin-labeled particle-associated antiseptic penetrated deeper into hair follicles in porcine skin than particles without antiseptic.

This study found that intradermal injections of group B vitamins and cystin B6 complex improved scalp circulation, supported hair growth, and reduced hair loss in patients with diffuse alopecia.

This article introduces a special issue of "Lasers in Surgery and Medicine" focused on dermatology and plastic surgery, but it presents no new research findings.

In this study, researchers found that in hairy guinea pig skin, minoxidil delivered via 40-nm nanoparticles had higher skin penetration than 130-nm nanoparticles, indicating nanoparticle size affects permeation.

This study describes trichilemmal keratinization as a distinct process of hair follicle keratinization that occurs in specific areas of the outer root sheath, illustrated using electron microscopy on dog hair.

This study discovered that the lipid in human hair follicles is mainly located in the hair cuticle and keratinized inner root sheath, distinct from sebaceous and epidermal lipids, suggesting a potential role as a "hair barrier.

This study suggests that vitamin D-upregulated protein 1 (VDUP1) might play a unique role in regulating the differentiation of epidermal cells.

This study observed that different hair types on Tianzhu white yaks have similar ultrastructures, but coarse hair fibers show distinct structural differences across body parts.

This study observed that hair follicle cuticular cells undergoing keratinization were significantly thicker than those in a normal hair shaft, due to incomplete loss of cytosol.

Hair restoration techniques improved rapidly in 2004, leading to more natural results, with a shift to microscopic methods and diverse treatments including medical management, cloning, and surgical techniques. Laser hair removal was also mentioned.

This study found that keratin derivatives with functionalized thiol groups improved binding to both natural and bleached hair fibers, suggesting a promising strategy for enhancing keratin's durability in hair repair.

This study demonstrated a method for delivering a photosensitizer, Ammi majus fructuum furocumarines, into hair follicles using calcium carbonate particles, followed by UVA irradiation, which led to significant pigment accumulation, indicating potential improvements for photochemical therapy.

This study found that low frequency sonophoresis may reduce percutaneous absorption of sodium fluorescein-loaded liposomes by partially blocking follicular pathways in the skin.

Sodium hypochlorite can effectively prevent and remove Staphylococcus aureus biofilms in atopic dermatitis at high enough concentrations.

This study concluded that the optimized caffeine-loaded nanostructured lipid carriers improved hair growth by enhancing permeation through skin layers more effectively than an existing market formula.

In this study, Monegy significantly improved hair repair in mice with epilate-induced hair loss, possibly through growth factor induction in hair follicles.

This review explores the structure and development of the hair cuticle, highlighting difficulties in studying some aspects and proposing new experimental approaches, but reports no new clinical results.
