So a client who i have been doing years a global colour and highlights always the same colour , she just text me saying that last time i did her hair she thinks she had an allergic reaction , she couldnt stop itching and her head was bumpy and lumpy could this happen as i havent changed anything and been doing for years , am going to do another skin test on her soon but just wondering if any others have had this experience? She did go on holiday the day after could this be it ? i put on 8.1 and 7.0 with 6% for ger global colour so it shouldnt be high pigment ?
