This review discusses recent advances in hair follicle research, highlighting therapeutic and cosmetic applications, but reports no new study results.

In this study, researchers using a multi-omics approach identified specific proteins involved in the hair follicle cycle of Inner Mongolia Cashmere Goats, finding that API5 affects apoptosis, while ribosomal proteins are highly expressed during the resting stage, providing insights into hair follicle growth and apoptosis.

This study found that hair follicle stem cells in the hairpoor mouse, a model for Marie-Unna hypotrichosis, lose their quiescent state, leading to a disordered hair cycle and contributing to alopecia.

In this study, the expression of certain hair follicle-related genes differed between growth phases in Angora goats, with HOXC13 showing overexpression during the anagen phase, potentially influencing the mohair's shine and texture.

This study found that overexpression of Gasdermin A3 in mice disrupts the hair follicle stem cell niche and causes hair loss through cell necrosis and abnormal hair cycle progression, without involving immune-mediated mechanisms.

This preliminary study found that Melandrium firmum extract may promote hair growth and inhibit 5α-reductase, suggesting potential as a candidate for treating androgenetic alopecia.

Mesotherapy and platelet-rich plasma treatments may help with hair loss, but their safety and effectiveness are still uncertain.

This study reported that the PTGER2 gene is strongly expressed in cashmere goat skin and its expression tends to decrease from the anagen to telogen stages of the hair follicle cycle.

This study found that Gp₄G increased hair length, papilla cell numbers, and versican deposition in treated animals, potentially through alterations in hair follicle phases and nucleotide concentrations.

This case report describes the first Indian patient diagnosed with short anagen syndrome, detailing the clinical and pathological characteristics of a 30-year-old woman with the condition.

This study found that melatonin administration effectively shortened the fur maturation period and altered hair follicle cycling in chinchillas.

The book discussed in this abstract is a comprehensive guide to hair analysis, detailing the latest methods and applications across various fields such as toxicology and drug monitoring, designed for both newcomers and experts in the field.

In this study, Lespedeza bicolor extract was found to enhance dermal papilla cell proliferation and extend the anagen phase in mice, suggesting its potential as a treatment for alopecia.

In this study, the researchers observed that inducing and then withdrawing β-catenin expression in a bigenic mouse model caused reversible changes in skin morphology, indicating dependence on β-catenin signaling.

This study found that Thai males with androgenic alopecia displayed lower average hair density in the occipital scalp compared to other Asian populations, but higher than those with advanced AGA.

This study reported that Tomorrowlabs HIF strengthening factor [HSF] hair restoration technology significantly improved hair thickness, density, shine, and elasticity, while reducing hair loss by an average of 66.8% and enhancing hair growth by up to 32.5% in subjects with androgenic alopecia over nine months.

This study found that miR-148a plays a significant role in regulating skin homeostasis and hair follicle cycling, influencing stem cell activity and development in mice.

In this study, FGF12 was found to promote hair growth in mice by inducing the anagen phase of hair follicles, suggesting potential for hair loss therapy.

This study concluded that controlled micro-injury induces hair regeneration and vitiligo repigmentation in mice, potentially through the Wnt/β-catenin pathway.

This study found that petroleum ether extract of Abrus precatorius leaves at 300 mg/kg promoted hair growth in animal models similarly to 2% minoxidil.

This study found that a 2.5% flavonoid-rich extract of Equisetum hyemale promoted hair growth in a rat model of chemically-induced alopecia, showing results comparable to 5% minoxidil.

This study found that low-fluence intense pulsed light promoted hair growth in C57BL/6 mice by inducing an earlier and prolonged anagen phase and activating the WNT/β-catenin pathway.

This article discusses the familiarity of identifying male androgenetic alopecia but presents no new research findings.

This study identified that blocking the PTGDR2 receptor in human hair follicles in vitro and in mice reversed the hair growth inhibition caused by PGD2, suggesting a potential approach for treating alopecia.

This study found that the ACTH/MC2R system is important for hair cycle regulation, with deficiencies in MC2R leading to altered hair growth phases in mice.

This case study reports a man with rapid hair thinning, whitening, and sparse beard, linked to an increased proportion of hair follicles in catagen or telogen phase and peribulbar lymphocytic infiltrate.

This study found that aging mice with an epidermal deletion of DNA methyltransferase 1 had a reduced number of hair follicles, due to decreased stem cell activation probability.

Some medications for inflammation can cause a condition with scalp rashes and hair loss, often linked to Crohn's disease, and may require treatment changes to prevent permanent hair loss.

This study observed that osteopontin mRNA levels in rat hair follicles vary throughout the hair cycle, peaking during the catagen phase and disappearing in the telogen and anagen phases.

The document explains different hair and scalp conditions, including common hair loss after pregnancy or illness, drug-induced hair loss, hereditary excessive hair growth, patterned baldness, autoimmune hair loss, and permanent loss due to skin disease, with generally limited treatment options.
