How do I get rid of yellow hair?

The easiest way to get rid of yellow hair is to wash it with a colorless shampoo augmented with violet food coloring gel. This process takes about 10 minutes and requires violet food coloring gel, colorless shampoo, hair conditioner, a towel and a hairbrush.

1. Tint the shampoo

   Unscrew the top of the shampoo bottle, and add a pea-sized dollop of violet food coloring gel. Cap the bottle, and shake it vigorously.

2. Apply the violet shampoo

   Wet your hair with hot water, and apply a generous handful of the violet shampoo. Rub it throughout your hair, and let it sit for at least two minutes. Rinse with cool water to seal the cuticle and help your hair retain the violet pigment.

3. Condition and dry your hair

   Apply a nourishing conditioner, and leave it on your hair for at least three minutes. Rinse with lukewarm water. Twist your hair to remove some excess water, then wrap your head in a fluffy towel for five minutes. Remove the towel, and brush your hair. Do not evaluate the color change until your hair is fully dry.

4. Evaluate the color change

   Examine your dry hair. If some yellow remains, repeat the violet shampoo treatment on the following day.
