1. Let the color develop
If you don’t want to use tin foil, you may also use a shower cap. Keep this on your head for at least 60 minutes so that your hair will absorb the color. After letting it stand, wash your hair thoroughly using herbal shampoo and then rinse. Apply conditioner afterwards and then rinse again.
The big advantage of using natural hair colorants to highlight your hair means that you can do the process as often as you want. There are no harmful chemicals or irritants in these juices and teas, so even people with sensitive skin can use them.
