To help protect against this, try using a color-enhancing shampoo every other day. RED Use a strawberry or vibrant shade of red. If you are already using one shade of color enhancing shampoo and would like to change to another, simply use a clear shampoo for a few days before switching to a new shade of color. Yellow tones in gray hair are the result of oxidation through exposure to sunlight. To counteract the yellow, use a blue or purple color enhancing shampoo once or twice a week.
Gray hair is coarser and dryer than other types of hair.
Use a moisturizing shampoo to help replenish the natural oils that gray hair tends to lose. Follow with a leave-in conditioner to help maintain manageability.
