Researchers found a new genetic mutation linked to a hair condition in a Japanese boy.

research The Endocannabinoid Tone Regulates Human Sebocyte Biology
The endocannabinoid system affects oil production and inflammation in skin cells.

research An Underlying Mechanism of Hair Loss in Acrodermatitis Enteropathica
Zinc deficiency disrupts hair growth and cycle, but zinc supplements can fix this.

research Effectiveness of Exosome Treatment in Androgenetic Alopecia: Outcomes of a Prospective Study
Exosome treatment safely increases hair density in male patients with androgenetic alopecia.

research Proceedings of the Ninth World Congress for Hair Research 2015
The 2015 Hair Research Congress concluded that stem cells, maraviroc, and simvastatin could potentially treat Alopecia Areata, topical minoxidil, finasteride, and steroids could treat Frontal Fibrosing Alopecia, and PTGDR2 antagonists could also treat alopecia. They also found that low-level light therapy could help with hair loss, a robotic device could assist in hair extraction, and nutrition could aid hair growth. They suggested that Alopecia Areata is an inflammatory disorder, not a single disease, indicating a need for personalized treatments.

research Alleviation of Multidrug Resistance by Flavonoid and Non-Flavonoid Compounds in Breast, Lung, Colorectal, and Prostate Cancer

research Moxibustion Improves Ovarian Function Based on the Regulation of the Androgen Balance
Moxibustion may help improve ovarian function by changing androgen levels.

research Development and Evaluation of Antisense shRNA-Encoding Plasmid Loaded Solid Lipid Nanoparticles Against 5-Alpha Reductase Activity
The new particle system could be a promising treatment for diseases related to the 5-α reductase enzyme.

research Association of Single Nucleotide Polymorphisms in the RAB5B Gene 3′UTR Region with Polycystic Ovary Syndrome in Chinese Han Women
Certain genetic variations in the RAB5B gene are linked to a higher risk of polycystic ovary syndrome in Chinese Han women.

research ATP-Dependent Chromatin Remodeling During Mammalian Development
ATP-dependent chromatin-remodeling complexes are crucial for gene regulation, cell differentiation, and organ development in mammals.

research Factors Regulating Quiescent Stem Cells: Insights from the Intestine and Other Self-Renewing Tissues
The document concludes that stem cell inactivity is actively controlled and important for tissue repair and balance.

research Biochemistry of Epidermal Stem Cells
The review found that different stem cell types in the skin are crucial for repair and could help treat skin diseases and cancer.

research Differential Expression of miR-93 and miR-21 in Granulosa Cells and Follicular Fluid of Polycystic Ovary Syndrome Associating with Different Phenotypes
The study found that certain microRNAs are higher in the cells and lower in the fluid of women with a specific type of polycystic ovary syndrome, and one microRNA could potentially help diagnose the condition.

research Quercetin and Polycystic Ovary Syndrome
Quercetin may help improve symptoms of polycystic ovary syndrome.

research Applications of Ultrasound-Mediated Gene Delivery in Regenerative Medicine
Ultrasound can help deliver genes to cells to stimulate tissue regeneration and enhance hair growth, but more research is needed to perfect the method.

research MiR-23b and MiR-133 Cotarget TGFβ2/NOTCH1 in Dermal Fibroblasts and Affect Hair Follicle Development in Sheep
Two microRNAs affect hair follicle development in sheep by targeting specific genes.

research MicroRNA-1246 Inhibits NFATc1 Phosphorylation and Regulates T Helper 17 Cell Activation in the Pathogenesis of Severe Alopecia Areata
A substance called miR-1246 may help treat severe hair loss by reducing certain immune cell activities.

research miR-195-5p Regulates Hair Follicle Inductivity of Dermal Papilla Cells by Suppressing Wnt/β-Catenin Activation
miR-195-5p reduces hair growth ability in cells by blocking a specific growth signal.
