Air pollution: Whatever is in the air around you can be absorbed by your hair. The most common source of yellowish pollutants is cigarette smoke.

Swimming pools : Chlorinated water can adhere to your hair and change the color of your tinted hair or can cause your natural pigment to change.
Medication you take is absorbed into the blood stream and will eventually end up on your hair.
Sun exposure: Hair is rarely without natural pigment. If your hair is gray or silver or if it is white mixed with darker strands. The sun is an oxidant. It will cause your natural pigment to lighten. When it lightens, it will take on a warmer hue, giving a yellowish look to all of the hair.
Air pollution: Avoid contaminated air. Stop smoking or stay out of environments where the air is smoky. Shampoo your hair as soon as you leave a smoky environment. Use clarifying shampoo once a week for extra cleaning.
Hard water: The best remedy for this is a water softener or washing your hair in bottled water instead of water out of the tap. Some shampoo manufacturers produce shampoo that is more effective in hard water and will help to clean the minerals from your hair. Visit your salon to receive an in salon treatment to remove minerals from your hair.
Chlorine: Enter a swimming pool with your hair already wet with tap water. Shampoo immediately after leaving the pool. Use shampoo formulated for swimmers.
