Most of the time while applying using color on your hair, it can look simply amazing and once the hair gets rinsed the entire look will change. But there are few products that can solve this problem such as a color corrector. The color corrector can be used along with the shampoo that you use to wash your hair. Make sure to purchase the color corrector that can be used only over the hair by going to a beauty supply shop. You must consult a hair specialist before solving the hair color problem to prevent further damage to your hair.
In case the hair becomes too dark try to wash your hair using Prell and avoid using it over the light hair. You can select green-toned hair corrector to get rid of unwanted red hair tones and use blue or violet corrector to clear brassy tones. You can use other hair color correctors that can be used over the gray and yellow tones. Try to mix equal amount of color corrector in the shampoo that will be used for washing your hair. You must also use same amount of the color corrector in the hair conditioner that will be used after washing the hair. The Prell must not be used on the hair that has been lightened, so use it only over the dark hair. The hair color correction will be able to build up gradually, so you have to wait patiently.
