In this study, magnesium was observed to penetrate human skin, with hair follicles significantly aiding this process depending on the concentration and duration of exposure.

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.

In this study, permanent alopecia after haematopoietic stem cell transplantation was found in 16% of patients and was significantly associated with conditioning regimens involving busulphan.

In this study using a porcine skin model, the researchers reported that smaller curcumin nanocrystals in xanthan gum gel showed higher passive skin penetration, while larger particles achieved deeper follicular accumulation.

This study describes permanent scalp alopecia in patients receiving chemotherapy, radiation, or both, and highlights the need for further research to identify causative factors and mitigation strategies.

A woman permanently lost hair on her scalp after a long surgery.

This correspondence comments on the unknown prevalence of permanent alopecia following high-dose docetaxel chemotherapy and highlights the need for further understanding and prevention strategies.

This case report describes a 22-year-old woman who developed persistent, non-scarring hair loss and premature ovarian failure following a myeloablative umbilical cord transplant for acute myeloid leukemia.

In this study, the researchers reported that while both propylene glycol and sodium lauryl sulfate enhanced finasteride's skin deposition, ethanol was the only effective enhancer of finasteride's permeation through the skin.

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 found that permanent wave lotion I extracts proteins from human hair, with molecular weights ranging from 5,000 to 65,000, which may elucidate hair damage mechanisms.

This case report describes a patient with permanent chemotherapy-induced alopecia who experienced full hair regrowth after treatment with low-dose oral minoxidil.

This study presents a rare case of alopecia totalis occurring after the use of permanent hair dye.

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 excerpt discusses website navigation and access details for JAMA Dermatology and reports no new research findings.

This study proposed a simple, rapid permanganometric method for determining minoxidil concentrations in pharmaceutical samples, offering comparable accuracy to chromatographic methods with recovery rates of 94.5 to 95.2%.

This study found that increasing collagen concentration to 2% in permanent wave treatments reduced hair damage but impaired curl formation.

In this review, researchers summarize drugs associated with scarring or permanent hair loss, notably after chemotherapy and tyrosine kinase inhibitor treatments, emphasizing the need for stronger evidence and long-term follow-up studies, as current findings are mostly from case reports.

This study investigated non-laser methods for removing permanent makeup using plant extracts, testing their decolorization effects on mice through tattooing and electroporation techniques.

This article highlights that permanent chemotherapy-induced alopecia can occur and is more commonly associated with taxane therapy, advising awareness among patients and clinicians.

Permanent hair loss after a stem cell transplant can be a sign of chronic immune system attack on the scalp.

This study found that washing hair after reduction in a permanent waving process allows for significant reformation of disulfide cross-links, enhancing the strength and elasticity of hair fibers.

This study verified that a new straightening process involving a flat iron, ammonium thioglycolate, and hydrogen peroxide may permanently straighten wavy hair by eliminating disulfide bond distortions.

This review explores how hair dyes and perms can damage hair structure and notes that while some adverse outcomes like skin irritation and allergic reactions have been reported, evidence from human studies remains inconsistent regarding potential risks, including cancer.

In this study, researchers found that using 0.75% aspartic acid as an intermediate agent for a permanent wave improved wave formation and retention compared to a control in virgin hair, also reducing cuticle damage and maintaining tensile strength.

This study found that permanent makeup pigments were applied at similar depths as traditional tattoo inks in mice but faded over time due to larger inorganic pigments.

In this study, treating hair with thioglycolic acid was found to alter disulfide bond patterns in keratin-associated proteins, shifting them from an ellipsoidal to a near-spherical shape.

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.

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 compared the protective effects of two conditioners, Protective factor C and Keratin, on hair damaged by perm treatment using a model of damaged hair.
