This review examines changes in hair physiology and treatment options for transgender patients on hormonal therapy but reports no new clinical findings, offering treatment recommendations based on the authors' experiences.

This study found that while all hair removal techniques increased axillary erythema and skin dryness, shaving caused less erythema but more dryness than plucking or waxing, without affecting post-inflammatory hyperpigmentation or other skin properties.

This article reviews Becker's nevus syndrome, covering its symptoms, causes, and cosmetic treatment options, without presenting new clinical findings.

This article reviews the causes and treatments of hirsutism, emphasizing the importance of considering ethnic and cultural norms when interpreting grading systems, and reports no new original findings.

A girl inherited excessive body hair from her mother and grandmother.

This chapter discusses management strategies for unwanted hair, focusing on the distinction between depilation and epilation, and reports no new clinical results.

This hospital-based observational study of 300 women with hirsutism found that polycystic ovarian syndrome was the main cause of moderate hirsutism, with dietary habits and lifestyle factors, such as frequent consumption of meat, fried food, and alcohol, significantly associated with the condition.

Results are not reported in this abstract, which outlines a study comparing how waxing and sugaring hair removal treatments affect the skin and hair condition in the bikini area across different age groups using qualitative case study methods.

In this study, the researchers identified traumatic styling practices, such as frequent hair straightening, as a dominant cause of alopecia among women aged 15 to 45 in a dermatology setting, noting that rural women also experienced inflammatory alopecia linked to different etiologies.

In this study, mouse sebaceous glands were found to require nerves for growth during active hair cycles, suggesting a nerve-dependent sebaceous gland cycle coordinated with hair growth.

This study found that ponytails with small fractions of gray hair have significantly lower swing height and higher damping, affecting the dynamic movement and appearance compared to those with fewer gray hairs.

This article explores the social and psychological factors driving male body hair grooming and the psychosocial effects of both hair removal and male pattern balding, without reporting new clinical findings.

Laser hair removal can be effective for people with darker skin tones.

This study found that clipping is the most effective method for anagen synchronization in adult rat models to mimic chemotherapy-induced alopecia, producing robust anagen phases without causing skin trauma.

This review discusses diagnostic and management approaches for hirsutism, emphasizing that most cases are due to polycystic ovary syndrome or obesity-related disorders, with idiopathic hirsutism often treated cosmetically.

This study found that hydrolyzed wheat proteins extensively penetrated both untreated and chemically treated hair, primarily occupying areas like the endocuticle and cortex.

Cold waving solutions quickly reduce cystine to cysteine in hair.

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

This case report describes a woman who developed green hair due to high copper levels in swimming pool water, exacerbated by hair treatments and inadequate water replacement.

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.

Hair care products clean, protect, style, color, and change hair structure.

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 reported that X-ray microscopy provides more intact images of hair's internal structure compared to transmission electron microscopy, particularly for observing fine details like cuticle coarsening and cortex cracks.

This study found that keratin fibers like human hair undergo thermal and mechanical transitions that can help assess changes from cosmetic processes such as bleaching and perm-waving.

In this study, human hair-carboxymethylated protein analysis showed that weathering for over 2.5 years can obscure electrophoretic patterns, while cosmetic treatments did not cause significant changes.

In this study, researchers observed that Sedum takesimense extract improved the surface properties, moisture retention, tensile strength, and wave formation of damaged hair compared to a water control, even after additional chemical and UV damage, suggesting its potential as a protective hair treatment.

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

This review discusses the chemical processes involved in hair styling and straightening and reports no new results; the authors highlight pregnancy safety with hair treatments during pregnancy.

This study found that, compared to oxidative treatments, reductive perm-waving more severely impacts the intermediate filaments in European human hair, while both treatments alter denaturation kinetics in a first-order manner.

In this study, researchers found that specific enzyme activities in young females' hair follicles were correlated with changes in hair shaft structure and properties, and permanent waving was associated with chemical changes that suggest hair damage.
