Brazilian keratin treatment (BKT) is a prevalent hair straightening method widely used by women in the world. The degree of concentration of formaldehyde safe for sensitive patients is still obscure. Report claims that these products contain intolerably high levels of formaldehyde. Yet, hair straightening products may lead to severe allergic contact dermatitis, by means of the responsible allergens such as formaldehyde and its releasers. This case report presents the case of a 37-year-old female patient developing extensive edema of the face and acute inflammatory changes in the scalp from chemical-induced irritation, on the day following the application of BKT to straighten her hair.
巴西角蛋白护理（BKT）是一种在全球被女性广泛使用的流行直发方法。对敏感患者安全的甲醛浓度仍不明确。有报道称这些产品含有高得无法容忍的甲醛含量。然而，直发产品可能通过甲醛及其释放剂等致敏原导致严重的过敏性接触性皮炎。本病例报告介绍了一名37岁女性患者的情况，在使用BKT直发后的第二天，因化学刺激出现面部广泛水肿和头皮急性炎症变化。
