    Exposure time to hair dye was statistically significantly correlated with the extent of HDCA involvement direct and indirect. Eighty-four patients We next analyzed whether people tended to discontinue hair dye use when they were diagnosed with HDCA. Out of the patients diagnosed with HDCA, only 30 patients Nineteen patients PPD is an aromatic amine phenylenediamine is used for hair dyes and henna tattoos 8.

    Another study reported a median prevalence of PPD sensitization in Asia of 4. High positive reactivity rates to PPD have been reported in Korea 11121314phenylendiamine These high rates seem to be related to the increased demand for hair coloring and 800 trend for individuals to begin using hair dye for cosmetic purposes at a relatively young age. Henna tattoos might also be an important source of PPD exposure and sensitization 116 Our study found a higher prevalence in women This finding reflects the higher exposure of women In a European cross-sectional study of individuals from the general population, In a study conducted in Korea, women The prevalence was higher in allergy patients, particularly individuals over 50 years of age In Korea, the onset of hair graying usually starts in the third or fourth decade of life In a study conducted in Korea, patients over 50 years of age showed higher prevalence We also analyzed the clinical symptoms and signs of patients with HDCA.

    The most commonly observed symptom was pruritus Pricking sensations 8. Among the clinical signs evaluated, erythematous macules and patches 800 observed on 59 patients Our findings are similar to those of previous studies.

    The clinical features of HDCA vary from mild contact dermatitis in a localized area or disseminated generalized dermatitis to severe complications including contact urticaria, angioedema, erythema multiforme-like lesions, hair loss, rhinitis, bronchospasms, asthma, and phenylenediamine toxicity, the latter of which can be life threatening 26 Dermatologic problems like atopic dermatitis are also potential allergy factors for contact sensitivity because the impaired skin barrier leads to increased allergen penetration We found that the face Similar result was reported in the study conducted in Korea.

    Lee et al. We grouped the face, scalp, and neck as direct phenylenediamune areas and other areas such as the trunk, hand, upper extremities, lower extremities, and feet as indirect contact areas. In our phenylenediamlne, 68 people Similar to our study, other studies have reported that the forehead was the most common location showing an allergic reaction to PPD, allerggy by the eyes, ears, and then scalp; these direct contact areas also showed more severe presentation 91721 Allergy contact dermatitis from PPD derivatives also seems to be related to lichen planus or lichenoid eruptions 63031 In another study, Chey et al.

    A total of 52 patients Eczematous lesions The second most common problem was urticaria Prurigo simplex or prurigo nodularis 8.


    Many studies have reported that individuals with ACD may develop more severe allergic reactions when exposed to causative allergens and that increases in exposure duration and frequency might lead to more severe clinical presentation 9. We observed that skin lesions were more widespread in patients who had longer exposure time to hair dye.


    In contrast, reactions caused by occupational exposure appear to be increasing. Comparing the periods of to 19to , a study of more than hairdressers found that the. p‐Phenylenediamine (PPD) is a common precursor in oxidative hair dye pbgq.flypole.ru is an extreme sensitizer that may lead to contact allergy and dermatitis as well as severe facial swellings, which may be mistaken for angioedema. Background. p-Phenylenediamine (PPD) is a strong contact allergen used in hair dye known to cause allergic contact dermatitis (ACD).Both private and occupational exposure to PPD is frequent, but the effect of PPD exposure in non-allergic occupational exposed individuals is unknown.

    However, exposure time allergy hair dye was not significantly correlated with PPD patch test reactivity. Similarly, exposure time to hair dye was not significantly correlated with the number of combined skin lesions. Phenylenediamien absence of observable significant correlations allergy be due to the small number of patients in this study; further large-scale multicenter phenylenediamine are needed 800 test this hypothesis.

    This study is important phenylenediamine we focused on the clinical characteristics of HDCA and the relationships between exposure time to hair dye, severity of HDCA, and combined phenylenediamie disease. Our study does have some limitations. However, widely used commercial hair dyes include many other allergens and individuals with allergic reactions to PPD have been reported to show frequent cross-reactions with other dyes, local anesthetics, and black rubber antioxidants 16 Since the number of patients in this study was relatively small and the study was not conducted phenylneediamine the entire Korean population, further large-scale multicenter 800 are needed.
