No, you should not dye your hair with products already in it.
Dyeing your hair requires a clean and product-free base to ensure the color properly adheres to the hair shaft. The presence of styling products, oils, or even excessive dirt can create a barrier, preventing the dye from penetrating evenly and resulting in a patchy or uneven color application.
Here's why it's crucial to have clean hair before dyeing:
-
Product Buildup: Hairspray, mousse, gel, and other styling products leave residue that coats the hair. This coating acts as a repellent, preventing the dye from reaching the hair's cuticle.
-
Oil Barrier: Natural oils produced by your scalp can also hinder the dyeing process. While a little bit of oil can protect your scalp from irritation, excessive oil can block the dye.
-
Uneven Absorption: If the dye can't penetrate evenly due to product buildup, you'll likely end up with a splotchy and inconsistent color result.
How to Prepare Your Hair for Dyeing:
- Avoid Washing Immediately Before: Don't wash your hair for at least 24-48 hours before dyeing. This allows natural oils to build up and protect your scalp from the chemicals in the dye, while not being so excessive as to block the dye itself.
- Skip Styling Products: Refrain from using any styling products, such as hairspray, mousse, or gel, for a few days before dyeing.
- Clarifying Shampoo (Optional): If you use a lot of product regularly, consider using a clarifying shampoo a few days before dyeing to remove buildup. However, use it sparingly, as it can strip your hair of its natural oils.
By starting with a clean base, you'll significantly improve your chances of achieving vibrant, long-lasting, and evenly distributed hair color.
