AI Article Synopsis

  • - The study investigates the complications associated with laser hair reduction, emphasizing the need to consider effects on scalp hair in addition to skin and ocular issues.
  • - It found that medical personnel using the Nd: YAG laser experienced a significantly higher increase in grey hairs over time compared to those using Alexandrite laser, indicating potential long-term effects on hair pigmentation.
  • - The research highlights the importance of protective measures for both scalp hair and eyesight to ensure the safety of laser providers, particularly in relation to their cumulative exposure to laser beams.

Article Abstract

Complications of laser hair reduction should be classified not only to skin and ocular complications but to skin, ocular, and scalp hair complications. Do not forget the plumes. Awareness about laser dangers is very critical. In this way, able to progress the security of both patients and laser providers. Does Nd: YAG cause more bad effect than Alexandrite on scalp hair melanin of laser providers and why? The study aimed at detecting the effect of cumulative exposure to scattered beam during laser hair reduction on the laser providers which may cause unexpected scalp hair melanin affection. The study included 150 female subjects: One hundred medical personnel engaged in laser-assisted hair reduction procedure; half of them were wearing head cover (hijab) and 50 female subjects not dealing with hair reduction laser systems (half of them were wearing hijab). Two laser devices were used: Alexandrite laser (GentleLase PRO® 755 nm, Candela Corp., Wayland, MA, USA) and neodymium-doped Yttrium Aluminium Garnet (Nd: YAG) (Synchro HP 1064 nm, Deka M.E.L.A s.r.l., Calenzano (FI), Italy) laser. A significant higher number of grey hairs in medical personnel (P < 0.001) was evident at the initial examination and at each follow-up visit thereafter. The number of grey hairs at initial assessment, after 6 months and after 1 year, was significantly higher in medical personnel dealing with Nd: YAG laser than those using long-pulsed Alexanderite laser (P < 0.001 each). A noteworthy positive correlation was found between working years, grey hair number at the start of study, and the progression (excess) in number of grey hairs after 1 year regardless of the laser system used. It seems that scalp hair pigment needs specific protection as does the eye pigment. Greater attention should be paid to possible long-term hazards particularly on service providers.

Mutations in the gene cause the most common form of human hereditary hearing loss, known as DFNB1. is expressed in two cell groups of the cochlea-epithelial cells of the organ of Corti and fibrocytes of the inner sulcus and lateral wall-but not by sensory hair cells or neurons. Attempts to treat mouse models of DFNB1 with AAV vectors mediating nonspecific expression have not substantially restored function, perhaps because inappropriate expression in hair cells and neurons could compromise their electrical activity.

Background: Exosomes are small extracellular vesicles (30-150 nm in size) that play a critical role in cellular communication, transporting proteins, lipids, and nucleic acids between cells. This literature review focuses on evaluating the potential benefits and limitations of exosomes in enhancing skin health and aesthetics through indications such as skin rejuvenation, hair restoration, and pigmentation disorders.

Methods: A thorough literature search was conducted on PubMed using specific MeSH, including "exosomes," "aesthetics," "cosmetic dermatology," "skin rejuvenation," "hair growth," and "wrinkle reduction.

Division of Dermatology, Faculty of Medicine, University of Ottawa, Ottawa, ON, Canada.

Discoid lupus erythematosus is a chronic, recurring, autoimmune skin disease causing annular, scarring plaques on the head and neck. Deucravacitinib, a tyrosine kinase 2 inhibitor in the Janus kinase inhibitor family, represents an emerging treatment option in systemic lupus erythematosus with potential applicability to discoid lupus erythematosus. We describe a 48-year-old woman with multiple treatment-refractory scalp plaques and associated alopecia treated with deucravacitinib.

Reinforcing chemically treated human hair with citric acid.

L'Oréal Research & Innovation, Aulnay-sous-Bois, France.

Article Synopsis
  • The study aimed to analyze how citric acid (CA) reinforces chemically treated hair by evaluating its effects on different treatment types like bleaching and perming.
  • Various physical and chemical testing methods showed that CA significantly enhances hair's structural integrity, increases its mechanical properties, and reduces harmful calcium levels in the hair.
  • Results suggest that the effectiveness of CA is influenced by the specific type of prior chemical treatment, with implications for improving hair care products that target damaged hair.
