This study measured elemental content in anagen hair fibers of Caucasian people aged 10-69 and found average levels of sulfur, zinc, calcium, and chlorine, establishing a baseline for future research.

This study reports the development of an artificial skin membrane incorporating hair follicles, intended as an in vitro model to better estimate drug permeation with less variability than current models used in transdermal drug delivery research.

This study found that chemical and photochemical oxidative processes modify the main classes of proteins in hair, confirmed through microspectrophotometric, fluorescence microscopy, and electrophoretic methods.

In this research, low-fluence light-based hair removal was explored, revealing its potential for at-home use with improvements in efficacy and safety, particularly for dark skin individuals, although further studies are necessary.

This study found that hair damage from sunlight and chemical processes like perms and bleaching varies in internal microstructure changes, suggesting that protective techniques should be tailored to the type of chemical treatment used.

In this study, researchers developed an environmentally friendly hair coating from casein proteins and tannic acid, enhancing the tensile strength of virgin Asian hair by approximately 21% compared to untreated hair, while maintaining elasticity.

In this study, researchers developed cationic liposomes encapsulated with keratin to improve the recovery of UV-damaged hair, finding that these liposomes significantly improved keratin penetration and reduced protein denaturation and lipid peroxidation, resulting in smoother hair surfaces compared to keratin solution alone.

This study found that melanin extracted from cuttlefish ink provided significant protection against UV radiation damage to human hair, suggesting its potential as a photoprotective agent in hair-care products.

This study found that genipin-based pigments, accelerated by riboflavin and blue-light photocatalysis, achieved commercial-level hair dye results with enhanced gloss and excellent color retention while reducing cuticle disruption, offering a potentially safer and faster alternative to traditional hair coloration methods.

This review discusses the current understanding of hair photodamage and photodegradation and reports no new findings; it highlights unresolved questions about radiation effects and melanin's role in different hair types.

Women's hair has more sulfur, and black hair has more calcium than white hair.

This study developed a novel system that can automatically estimate hair loss parameters from images without expert input, reporting satisfactory results from testing on samples collected in Kolkata.

Riboflavin with blue light speeds up hair dyeing, making it faster, safer, and long-lasting with less hair damage.

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.

In this study, murine follicular cell aggregates developed into hair-like structures in culture, which upon implantation into mice skin matured into complete hair follicles, suggesting potential for treating hair loss.

This study observed that a 3D culture model of hair follicle cells showed an anagen-like phase between days 3 to 6 and transitioned to a catagen-like phase by day 7, highlighting cell differentiation and structural development over time.

This review discusses the pathogenesis, causes, and treatments of hirsutism but provides no new clinical findings; the authors emphasize the strong impact of hirsutism on quality of life.

This review discusses various hair removal techniques, particularly focusing on laser hair removal, and reports no clinical results; it emphasizes the need for ongoing research to assess effectiveness.

In this study, researchers created a new molecular salt from minoxidil and 2,4-dihydroxybenzoic acid, finding it superior to raw minoxidil for promoting hair growth in a mouse model, suggesting it may be a promising candidate for treating hair loss.

This study reveals that overexpression of Wnt3 in transgenic mouse skin leads to a short-hair phenotype and cyclical balding due to structural defects in hair shafts, highlighting a role for WNT signaling in hair growth regulation.

This study found that activating the erbB-2 oncogene in transgenic mice led to severe skin abnormalities and fatal defects, indicating erbB-2's significant role in skin and hair follicle development.

This review discusses the advantages and limitations of various hair loss evaluation methods but reports no new results; it emphasizes the importance of cautious interpretation for these diagnostic tools.

This study suggests that label-retaining cells in the hair follicle contribute to follicular renewal, indicating a specific role in the hair cycle by proliferating during the late telogen phase.

This study concluded that intense pulsed light treatment effectively thinned hair to achieve a natural look after hairline correction surgery in East Asian women with naturally thick hair.

This article discusses the characteristics, diagnosis, and clinical presentation of different variants of lichen planopilaris on the scalp, with emphasis on cicatricial alopecia and the importance of clinical and trichoscopic monitoring; it presents no new clinical results.

This case report describes a patient who experienced proton-induced alopecia after proton therapy for a frontal meningioma, which was effectively treated with topical minoxidil, resulting in full hair regrowth after 4 months.

Sericin hydrogels heal skin wounds well, regrowing hair and glands with less scarring.

This study developed microfluidic-assisted GelMA-MSC/HAD-EPC microspheres that efficiently generated hair follicles in nude mice, suggesting a promising strategy for advancing hair-regenerative medicine.

This study found that aminomethylpyrazole compound 10l inhibited hair growth in a mouse model and showed a low risk for photo-irritation, though it was slightly less effective than eflornithine.
