Here's why:
* Box color is primarily a deposit-only color: It works by depositing pigment onto the hair shaft, rather than removing existing color.
* Lifting requires bleach or developer: To lighten hair, you need a product that can break down the existing color molecules. Box color typically does not contain these ingredients.
* Using box color to lift can lead to unwanted results: You might end up with uneven color, brassiness, or damage to your hair.
If you want to lift your hair color, you should consult a professional hairstylist. They can assess your hair condition and use the appropriate products and techniques to achieve the desired results safely and effectively.
