There is a product at Sally Beauty Supply Stores called 'Gray Magic' ....The use of about 10 to 20 drops added to your formula will help cover the gray. Hence, Gray Magic! Don't freak out over the color of the product as you put it in your formula as it has a orange rust color coming out of the bottle, and does not effect the end color, it just allows the gray hairs to be covered.
