This study found that the reproductive function of female hairdressers may be negatively affected by long-term exposure to permanent-waving solutions containing thioglycolic acid, raising concerns about its potential carcinogenic effects.

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 CMAD wool keratin may protect human hair from damage during repeated bleaching and permanent waving treatments.

This study found that thioglycolic acid molecules in hair treatments are primarily located in intrafibrillar unordered areas, where they redistribute disulfide bonds.

This review discusses the causes, evaluation, and treatment options for hirsutism in women, but reports no new clinical results.

This review discusses laser hair removal, its scientific background, and treatment optimization but reports no new experimental findings.

This study found that hirsutism in females with facial hair causes significant psychosocial impact and financial burden, with laser therapy being notably costly compared to other treatments.

This review from JAAD Reviews provides a comprehensive overview of hypertrichosis, discussing its diagnosis, treatment options like topical and laser therapies, and special psychosocial considerations for pediatric patients to better support clinicians and researchers in managing this condition.

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 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 study found that permanent waving treatment partially disrupts the α-helical structure in human hair microfibrils, primarily during the initial reduction phase, rather than just affecting disulphide bonds.

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.

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

Cold waving solutions quickly reduce cystine to cysteine in hair.

In this study, the authors concluded that a hydrolyzed eggwhite protein treatment promoted the reconnection of disulfide bonds in excessively bleached hair, after reduction and oxidation processes in permanent waving.

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.

This study found that permanent waving treatment induces structural changes in the cortex proteins of white human hair, significantly reducing its tensile strength without altering the S-S band intensity.

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 waving virgin human hair with thioglycerol at pH 9.0 using ammonia solution caused less damage than using thioglycolic acid, while maintaining good waving efficiency.

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 found that chemically modifying hair with 2-iminothiorane hydrochloride improved the permanence of hair setting without damaging the hair by increasing disulfide bonds.

Birth control pills and anti-androgen medications help manage hair growth, acne, and hair loss in women with PCOS.

This article discusses the various manifestations and diagnostic challenges of polycystic ovarian syndrome and reviews its associated symptoms and clinical heterogeneity but reports no new clinical findings.

In this study, hair damaged by permanent dye showed signs of recovery over time, with near complete restoration to its original state after eight weeks.

This study found that the viscosity of silicone oil in hair treatments significantly affects wave curling performance and hair damage, with untreated and chemically treated hair showing different optimal viscosities.

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 study reviews natural hair and scalp care methods, highlighting the importance of plant-derived ingredients and scalp type diagnostics for effective trichological management and optimal hair health.

This review discusses various aspects of unwanted facial hair, including its psychological impact and current treatment options, and reports no new clinical results from the satellite symposium at the EHRS Meeting.

This study found that the long-pulsed ruby laser effectively delays hair growth and has the potential for permanent hair removal with minimal pain and side effects, offering an advantage over traditional hair removal methods.

This study found that permanent wave treatment accelerates hair degradation after protease exposure, showing significant morphological differences compared to untreated hair and linked to damage from Alpha-helical region denaturation.
