Artificial yellow coloring, chlorine and smoke are prime causes of yellowing in gray hair. To remove yellow streaks, avoid the causes, strip the hair and use a toning shampoo. Removing yellowing in gray hair takes as little as regular shower time and requires clarifying shampoo, toning shampoo, bleach and a water filter.
- Avoid the causes
Shampoos and conditioners with a yellowish tint can deposit that color on your hair, so switch to clear products instead. Smoking is another prime cause, so avoid smoke-filled places, and stop smoking yourself. If your water contains heavy concentrations of chemicals such as chlorine, install a water filter in your shower.
- Strip the hair
Buy a high-quality clarifying shampoo formulated to remove build up from the hair. Use it every time you shampoo until you notice the yellow fading. Follow with a moisturizing conditioner as clarifying shampoo also strips natural oils from the hair.
- Chemically strip the hair
If the yellow tint is very dark, such as from smoking, chemical stripping may be necessary. Make a shampoo cap of equal parts bleach, processor and shampoo. Leave the shampoo cap on for 15 to 20 minutes, and shampoo out.
- Use purple shampoo
To give gray hair a snow-white or silver appearance, shampoo with purple shampoo once a week. Look for shampoos formulated to tone hair.
