Chemical treatments damage hair more than UV exposure, making it thinner and less flexible.

This study identified 63 genetic loci associated with male-pattern baldness, uncovering genes and pathways that may help develop treatments and suggesting its connection to other human conditions.

Male pattern baldness is largely genetic, linked to the androgen receptor gene, and may relate to certain health issues.

This study found weak epidemiological associations between male pattern baldness and coronary heart disease, but no significant genetic link, though specific loci shared risks with other conditions.

This study found that local refinement of hair follicles into higher order patterns can occur without the core planar cell polarity system, but global alignment with body axes requires its function throughout development and regeneration.

This study describes a new radiation method called three-dimensional moving field radiation therapy, which showed improved tumor targeting and reduced damage to surrounding tissues compared to traditional one-plane methods.

This meta-analysis found that male pattern baldness is associated with an increased risk of aggressive prostate cancer and benign prostatic hyperplasia.

This article discusses the use of atomic force microscopy for examining human hair surfaces in dermatology, cosmetics, and forensic science, but presents no new research findings.

This study found that oxidative treatment with peracetic acid dissociates some disulfide bonds in human hair fibers while maintaining the crystalline structure, suggesting different mechanisms stabilize different regions of intermediate filaments.

This study found that mouse embryoid bodies adhered quickly and differentiated efficiently into cardiomyocytes on negatively charged poly(sodium p-styrene sulfonate) hydrogels, similar to their behavior on gelatin-coated polystyrene.

This review details the development of the alpha-helix model for protein structure proposed by Pauling and Corey and confirms its validity through X-ray studies of myoglobin and lysozyme.

This research suggests that classical labor motivation theories may be losing relevance in a mobilization economy, where employee motivation increasingly centers on primary needs like personal safety and job security.

The abstract contains only graphic design specifications and reports no new research findings.

Hard α-keratin in hair has a unique, nonordered structure, different from other fibers.

This study found that diabetic individuals had significantly lower hair levels of chromium, manganese, and copper, but higher iron levels, compared to non-diabetic controls.

This study found that patients with premature hair graying had lower serum levels of iron, copper, and calcium, which correlated with the severity of graying.

This study found that inducing miR-205 reduces actin contractility and stiffness in hair follicle stem cells and progenitors, stimulating hair regeneration in both young and old mice.

This study observed that mast cells and increased collagen and elastic fibers in the scalp may contribute to male pattern hair loss, but additional research is needed for further understanding.

This study found that multiphoton microscopy effectively visualizes the microstructure of in vivo mouse skin, offering a clear view of various skin layers and components like corneocytes and collagen fibers.

This study reported that a magneto-responsive transdermal microneedle system delivered Minoxidil effectively and significantly increased hair density by 800% in mice with androgenetic alopecia after 10 days.

This study confirms that the proposed universal model for hard α-keratin structure applies to all known forms across various mammalian species.

This study reported that polyamine levels, especially N-acetyl polyamines, were higher in the vertex region of the scalp than in the occipital region in patients with male and female pattern hair loss.

Certain proteins involved in DNA modification may affect the genetic changes in systemic lupus erythematosus and could indicate the disease's activity.

This chapter provides an overview of the complex chemical and physical structure of the hair surface, detailing how factors like ethnicity, environmental stress, and cosmetic treatments can alter its properties and influence the adhesion of hair care products.

This study found that treatments like abrasion, bleaching, and CETAB application affect hair fiber shear modulus differently, with moisture levels notably impacting bleached fibers more than untreated ones.

I'm sorry, but I can't provide a summary without the content of the document.

This study found that microfibrils play a crucial role in shaping permanent waves by thioglycolic acid, and treating damaged hair with hydrolyzed keratin improved both waving efficiency and hair damage.

This study found that Par3 plays a crucial role in maintaining epidermal homeostasis by regulating Rho/actomyosin contractility and ensuring mitotic accuracy, with potential implications for other self-renewing epithelia.

This study discusses that permanent hair straightening can be achieved at neutral or acidic pH conditions, with varying effects on cystine and lanthionine levels, by inducing supercontraction of the hair fiber.
