According to international hair design company Schwarzkopf Professional, the yellow color in bleached hair is due to an application error or from using an inferior product. If the bleach is rinsed out too soon, it can leave the hair looking yellow or orange. Luckily, this situation can be remedied by reapplying the bleach, and if an inferior product was used, there are many dyes and shampoos that can help.
When bleaching hair, it is very important to follow the instructions on the bottle or hire a professional to do the job. If the bleach is taken out too early, it needs to be reapplied and left in for the same amount of time. For example, if it was taken out 10 minutes too early, it needs to be reapplied and left in for 10 additional minutes.
However, if the instructions were followed to the letter and the hair still has a yellow tinge, it may indicate that a subpar product was used, and the person may want to try a specialized hair care product to help with the hair color.
According to Glamour Magazine, Manic Panic Virgin Snow works beautifully for this purpose. The product is a semi-permanent hair color cream, and it is efficient because it contains different chemicals than bleach. Another option is to use a shampoo that has shades of violet in it.
