Topical thiols may prevent hair loss caused by certain chemotherapy drugs.

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.

In this study, reducing agents like ammonium thioglycolate, L-cysteine, and sodium sulfite in shampoo effectively decreased hair flyaway and frizz without causing damage, as no critical hair damage was observed in structural and tensile strength assessments.

In this study, researchers examined juglone's potential as a restoring agent for hair keratin damaged by permanent or bleaching treatments, finding that juglone formed Michael adducts with cysteine residues, leading to a more regular hair surface as observed via IR spectroscopy and SEM analysis.

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.

This study observed that combining hair dyeing with sodium hydroxide relaxers drastically increased protein loss in Caucasian virgin dark brown hair, while ammonium thioglycolate or guanidine hydroxide relaxers caused less damage.

This study found that glyoxylic acid caused more protein loss in hair compared to traditional alkaline straighteners, though both types of treatments showed comparable effects on hair tensile strength.

Hair straightening methods have advanced to improve effectiveness and reduce damage, but still rely on heat and chemicals.

This review examines the design and evaluation parameters of depilatory formulations but reports no new empirical findings.

In this study, five women with minoxidil-induced hypertrichosis achieved complete hair removal using a calcium thioglycolate depilatory agent, with minimal or no skin irritation.

In their review, the authors discussed the increasing issue of allergies to hair products, highlighting common allergens such as hair dyes and topical minoxidil, and outlined diagnostic methods and alternatives for those affected, particularly addressing higher risks among hairdressers due to professional exposure.

This review examines the science and technology behind temporary and permanent hair straightening, discussing the processes, potential advancements, and considerations for reducing adverse effects, but does not report new research findings.

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 found that adding rose hip extract to permanent wave solutions increased wave effectiveness and reduced hair damage, although variations in hair type may affect the results.

This study investigated the safety and effectiveness of two thioglycolate chemical depilatory creams for full genital hair removal in men and women, finding acceptable dermal tolerance despite some instances of irritation, supporting their use for pubic hair grooming.

High temperatures and certain chemicals can significantly change the amino acid content in human hair.

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 minoxidil effectively manages various types of severe hypertension but can cause side effects such as sodium retention and tachycardia.

Minoxidil controls blood pressure effectively, but may cause side effects like hypertrichosis.

This study found that a sucrose-based crosslinker can effectively straighten hair and maintain durability in high humidity and through repeated washings without affecting the hair's tensile properties or causing surface damage.

This review discusses the effects of chemical hair straighteners and reports associated side effects like scalp inflammation and hair damage, noting the variability of findings and the need for further research.

Keratin peptides can change hair shape gently without harsh chemicals.

Avoiding dyed wigs and clothing improved severe allergic reactions in a woman treated with diphencyprone.

This study found that traction alopecia risk was higher in adults than children and increased further when traction was combined with chemically relaxed hair.

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

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.

This study found that chemical hair straightening significantly reduced hair curl and improved smoothness and shine, but did not significantly affect transverse fissures or split ends, indicating potential benefits with some side effects.

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.

Minoxidil effectively treats severe hypertension but may cause side effects, so careful monitoring is needed.

Minoxidil helps hair cells live longer and grow longer.
