As well as the undesirable effects listed above, there are more serious health concerns that are potential problems from chemical hair colorants. While there is some debate as to the reality of the problems from hair coloring, the risk simply does not need to be taken.
Natural hair colorants such as the plant powders Henna, Indigo, Cassia, and Amla can safely be used to enhance or change your hair color. They are plant powders that are mixed with lemon juice, water, and/or yogurt, in your own home, to make a paste that is applied to your hair and scalp.
