Woeber's Mayo Gourmet Kickin' Buffalo Mayonnaise, 11 fl oz

This is the best root cover up I've ever used. It perfectly covers my gray and looks natural. I have a couple different colors and I can mix them to exactly match my hair color. It doesn't take much of it to cover or highlight so they last a long time. I've recommended this to several people and they love it! It's easy to use and the dual ended brushes let you do roots or put highlights in your hair and it completely washes out.

In my more mature years I have developed a thinning part which to me is bright white after washing my hair and I am a brunette. To combat that I use this product so the part is more "light brown" verses white and so noticeable. My hairdressers love it too and now encourage their clients to use it. It is one product I use daily and never go without. Lasts me about 3 months.
