Here's a breakdown:
* Theory: The acidity of tomato juice *might* help to neutralize some alkaline components of the dye that contribute to the odor.
* Anecdotal Evidence: Some people swear by it, claiming it helps.
* Lack of Scientific Proof: No studies have been done to prove its effectiveness specifically for removing hair dye smell.
* Alternative Solutions: There are other options like using shampoos specifically formulated for color-treated hair and deep conditioners, that address the smell issues.
Therefore, while it might be worth a try, don't rely solely on tomato juice. Consider more effective, scientifically-backed methods for managing hair dye smell.
If you do want to try tomato juice:
1. Apply to damp hair.
2. Let it sit for 15-30 minutes.
3. Rinse thoroughly.
4. Follow with a conditioner.
Be aware that tomato juice *could* potentially affect the color of your hair, especially if it's very light or bleached. Always do a strand test first to see how it reacts.
