This issue contains notes by Dr. Bradley Wolf and mentions comments by Dr. Jerry Cooley, but it presents no new research findings.

This study found that hair care products containing fermented papaya, fermented mangosteen, and caffeine significantly inhibited hair loss, increased hair density and thickness, and improved hair follicle structure in individuals with androgenic or diffuse alopecia over three months compared to placebo and caffeine controls.

In this case-control study, researchers observed that smoking and lighter hair color significantly increased the risk of developing androgenetic alopecia, with older individuals and women showing higher prevalence rates, while hair thickness and shape were not linked to increased alopecia risk.

This study found that a herbal hair oil formulation from various plants showed good hair growth and weight without irritation, suggesting potential for improving hair growth.

This study found that applying glycosaminoglycans fractions from ascidian tunics stimulated human follicle dermal papilla cell proliferation and, when used on mice hair for 28 days, produced a hair growth effect comparable to Minoxidil.

This case study describes a rare instance of alopecia universalis in a Japanese patient following an mRNA COVID-19 vaccination.

This review discusses the phytochemical and pharmacological properties of Jatropha dioica, highlighting its potential uses in traditional medicine and the need for more scientific validation of its effects.

This review compiles evidence indicating that rosemary essential oil may enhance cognitive function, sleep quality, mood, and pain management in aromatherapy; however, it also notes potential allergic reactions, emphasizing caution in its use.

This study reports that Broussonetia papyrifera extract significantly increased hair count over 12 weeks in a small clinical trial and promoted dermal papilla cell proliferation in vitro by regulating WNT-β-catenin and STAT6 pathways.

This study found that bufotalinin, derived from Merremia peltata leaves, may enhance hair growth by acting as a potential androgen receptor antagonist in rabbits.

This study reported that rice bran oil from the Thai rice variety BB4CMU showed potential in promoting melanin production and inhibiting steroid 5α-reductase, suggesting a natural option for hair revitalization.

This review assessed dermo-cosmetic treatments using prebiotics, probiotics, synbiotics, and other biotics for acne and scalp disorders, finding potential benefits, especially with multi-strain or synbiotic formulations, although challenges like formulation stability and the need for larger trials persist.

This review highlights various plant-based and herbal treatments that reportedly help prevent hair loss and encourage hair growth. It also explores the molecular mechanisms, identified plant compounds, recent technologies such as nanoarchitectonics, and patents related to hair growth promotion.

This review discusses the diverse functions and therapeutic potential of ectopic olfactory receptors throughout the body, emphasizing their roles in various cellular processes and potential in cancer detection and therapy, but reports no new clinical results.

This study examined the factors contributing to gray hair, such as genetics and lifestyle, and found that while graying correlates with some health conditions, it is primarily a physiological process rather than a pathological one.

This study found that estrogen can cause reversible suppression of the hair cycle by inducing premature catagen and maintaining the telogen phase without damaging the hair follicle stem cell niche or the signature gene expressions of dermal papilla cells.

This review discusses telogen effluvium, including its triggers, clinical presentations, and management options, and does not report new research findings, emphasizing the need for identification and exclusion of underlying causes.

This study observed that certain herbal extracts may promote hair growth and inhibit hair loss in cell lines by affecting specific protein expressions similarly to minoxidil.

This review discusses pili torti, a rare hair shaft disorder, and reports no new clinical results; it emphasizes the need to investigate underlying conditions in affected individuals.

In this randomized controlled study, the researchers found that an herbal extract combination showed similar efficacy to 3% minoxidil solution in treating androgenetic alopecia over 24 weeks, with no significant safety concerns, suggesting it might be a viable alternative treatment.

This review discusses the roles of androgens and androgen receptor in skin diseases like acne and hirsutism, and highlights the promise of antiandrogen drugs, reporting no new clinical findings.

In this study, a botanical extract and minoxidil showed similar effects in vitro by reducing pro-inflammatory cytokines and 5α-reductase expression while increasing growth factors VEGF and KGF in human keratinocyte cells, suggesting potential for further in vivo research.

This systematic review found that topical adenosine may increase hair thickness and density while reducing hair loss, but the strength of evidence is low due to issues with trial design and sample size.

In this study, testing Annurca apple extract on human follicle dermal papilla cells indicated its potential to prevent patterned hair loss by reducing oxidative stress and increasing factors involved in hair growth.

In a 3-month study, over 90% of healthy women experiencing self-perceived hair thinning reported that the nutritional supplement DEEPLY ROOTED improved their hair growth, volume, and quality, without significant adverse effects.

This study highlights promising methods for converting food waste into valuable resources such as biogas, bioethanol, biodiesel, fertilizers, and antioxidants through processes like fermentation and anaerobic digestion, emphasizing the need for robust large-scale technologies to optimize this "waste to value" transformation.

In this study, researchers used atomic force microscopy to capture and analyze morphological changes in the surface of healthy hair, identifying features such as pitting and rod-shaped macro-fibrillar elements, which could inform future research on hair conditions and care.

In this study, 32 healthy adults with hair fall complaints applied a hair serum daily for 60 days, resulting in statistically significant improvements in hair growth rate, thickness, and density, without any reported adverse events.

In this study, N. ottonis cactus cell extract applied to mice promoted hair growth and increased the number of hair follicles, suggesting its potential as a hair-growth-promoting agent.

This review collected findings on the various cosmetic and therapeutic properties of tea extracts, highlighting their antioxidant, anti-inflammatory, and photoprotective effects among other benefits for skin and hair care.
