This article describes how to identify allergic contact dermatitis resulting from hair dye, and outlines interventions and prevention principles for those who wish to continue dyeing their hair despite being allergic. Hair dye chemicals thought to be the most frequent sensitizers are discussed with instructions for health care providers on how to counsel patients about techniques to minimize exposure to allergenic substances. This framework should allow many patients to continue dyeing their hair without experiencing adverse side effects.

Toluene-2,5-diamine sulfate (PTDS), also known as toluene diamine sulfate or 2,5-diaminotoluene sulfate, is an aromatic amine that can be used as a paraphenylenediamine (PPD) hair dye alternative. Patients may develop contact allergy to PTDS, and it is often omitted from standard patch test screening series, possibly leading to underdiagnosis. The American Contact Dermatitis Society named PTDS the Allergen of the Year for 2025, aiming to raise awareness of its dual role as both an allergen and an alternative for some PPD-allergic individuals.

Objective: This research investigated the possible shielding properties of BB (Berberrubine) against the harmful auditory effects of cisplatin, preliminarily delving into the underlying mechanisms responsible for this protection.
Methods: HEI-OC1 cell viability was determined using a Cell Counting Kit-8 (CCK-8). The impact of BB on cochlear hair cells was studied through cochlear explants culture.

Matrix-assisted laser Desorption/Ionization Mass Spectrometry Imaging (MALDI MSI) is an analytical technique used for the spatial mapping of drugs, explosives, and organic samples, making it a game-changer in Forensic examination. It detects a wide range of biomolecules in their native state without specific tags, antibodies, labels, and dyes. This review aims to highlight the advancement of MALDI-MSI over time and its impact on Forensic Science due to high-resolution molecular imaging.
