Here's why:
* It's extremely unpredictable: Lightening activator is designed to lift the natural pigment of your hair. Adding it to red dye will not guarantee a red color. The results are highly likely to be uneven, patchy, and potentially damaging.
* It can be dangerous: Mixing chemicals without proper knowledge and experience can cause severe chemical burns, hair breakage, and other hair damage.
* It's not the right approach: For black hair, a direct red dye will not be strong enough to overcome the dark pigment. You'll need to lighten your hair first before applying any red dye.
Instead of this method, here's a safer and more effective approach:
1. Consult a professional: A hairstylist can assess your hair and advise on the best course of action for achieving your desired red shade. They can also help you choose the right products and techniques for safe and effective color change.
2. Consider a color remover: If you want to avoid harsh bleaching, you can use a color remover to lighten your hair before applying red dye. However, be aware that color removers can also damage your hair.
3. Follow the instructions carefully: When using any hair color product, always read and follow the instructions carefully.
Remember, your hair health is important. Don't risk damaging it with unsafe techniques.
