One can use cranberry juice to boost the vibrancy of red hair. For the best results, pour the juice onto hair and let it sit for 5 or more minutes.
When dying hair with cranberry juice, try to find 100 percent natural juice. The higher the concentrate, the better the results will be. Before applying the juice, wash hair. Then generously apply the juice so that it coats the entire head. Comb the hair so that the juice is evenly distributed, and leave the juice on the hair for at least five minutes. The longer the juice is on the hair, the more vibrant the effect will be. Redheads who want especially vibrant color should leave it on for 30 minutes to an hour. Once a sufficient amount of time has passed, rinse the juice out of the hair. Then apply a conditioner. This will help preserve the color.
There are a number of other do-it-yourself hair color fixes. Cherry flavored Kool-Aid can be used to brighten faded red locks. Brunettes should try rinsing their hair in coffee, which can neutralize brassy tones. People with blond hair can enhance color with chamomile tea, which adds a buttery warmth to the hair.
