This article reviews various hair straightening methods, discussing their mechanisms and potential effects on hair, but it reports no new clinical results.

This article reviews the use of the Nd:YAG laser for hair removal and reports no new research findings.

This study found that the Epilight multiple wavelength pulsed-intense light source was effective for long-lasting hair removal, particularly in individuals with dark hair and light skin.

This article reviews the current practices and interpretations of research data on permanent waving and hair straightening, but does not present any new research findings.

This case report described cosmetically significant hair regrowth in a 39-year-old woman with permanent chemotherapy-induced alopecia after continuous oral minoxidil use.

This review discusses the psychological importance of hair and explores how various hair cosmetics can affect hair health, emphasizing that certain products can lead to acute hair problems when repeatedly altering the natural style.

This study observed that repeated perm treatments decrease disulfide bonds in hair due to their conversion largely into cysteic acid, affecting the waving efficiency depending on the reduction agent used.

This review discusses the historical, legal, and clinical aspects of electrolysis and thermolysis, highlighting potential risks due to the lack of standardized training for electrologists in the United States, but reports no new clinical results.

This study observed that unpigmented keratinocytes saturate quickly with foreign substance uptake compared to pigmented melanocytes, where melanin significantly enhances binding.

In this study, radial shockwave therapy significantly improved muscle spasticity, ankle range of motion, and functional abilities in children with spastic cerebral palsy, suggesting it may help them achieve greater autonomy in daily activities.

This study found that using a bicomponent reduction system with TGA and DTDG for hair straightening limited hair damage by forming only thiol groups, while a TGA-only system formed more damaging mixed disulfide groups.

This article reviews two new legislative measures affecting domiciliary care workers in Wales and reports no new research results; it highlights implications for labor law and devolution debates.

This study found that stress and its related symptoms were highly prevalent among university students in Egypt during the third wave of the COVID-19 pandemic, with most reporting negative coping strategies.

This study analyzed the swelling behavior of human hair during permanent waving treatment, finding that both the microstructure and macrostructure of intermediate filaments swell simultaneously at the initial stage, and while partially destructed by reduction, they are considerably restored through oxidation.

This study found that a combination treatment of laser photobiomodulation and plasma jet therapy was effective in improving alopecia areata in a 38-year-old woman after 14 sessions over three months, as evidenced by comparative photo documentation.

This article discusses the role of cosmetic hair care products in hair loss and concludes they do not cause it, suggesting a need for clinicians to understand the hair cycle and cosmetic practices for accurate diagnosis.

This study found that digital perm treatments using sodium thioglycolate lotion led to the most significant reduction in protein content and greater hair damage compared to other methods and lotions.

This study found that an enzymatic method effectively identified chemical treatments like perming and dyeing by detecting higher degradation in treated hair compared to untreated hair.

Hair care products are important for appearance and self-esteem, and choosing the right ones can help maintain healthy hair.

In this study, permanent waving treatments, especially those using lotion B and repeated procedures, were found to significantly damage hair protein content and physical properties.

In this study, frequent use of hair straighteners/relaxers and pressing products was associated with an increased risk of ovarian cancer, with potential variation in risk by tumor type noted for permanent hair dyes.

This review discusses various theories of skin aging and the importance of using professional and at-home skincare solutions, but offers no new empirical findings.

In this study, carboxymethylalanyl disulfide keratin was shown to effectively prevent hair damage during repeated bleaching and permanent waving treatments.

This article reviews safe and effective hair removal options for dark-skinned patients and reports no new clinical results.

This study evaluated an 808-nm diode laser at different fluences for permanent axillary hair removal in Korean women and found that high-fluence treatment (14 J/cm2) effectively reduced hair density and thickness, with no significant difference in comfort compared to lower fluences.

This study found that shampoo and conditioner do not alter hair's molecular structure, while perming treatments significantly affect keratin and intermediate filament structures due to bond alterations.

This study found that intra-follicular Wnt signaling and dermal BMP signaling oscillate differently during hair cycling in mice, affecting hair wave propagation and phases of hair growth.

This review discusses the application of active transdermal technologies in cosmetic devices for skin restoration and enhancement, reporting no new clinical results.

In this study, researchers using the hair paradigm highlighted how periodic patterning and compartmentalization enable diverse regenerative behaviors, including region-specific renewal cycles and emergent properties like regenerative waves in organ populations.
