– Before applying the dye, perform a patch test to check for any allergic reactions or sensitivity to the product. Follow the instructions in the kit.

3. **Prep Your Hair:**
– Start with clean, dry hair. Don’t wash your hair right before coloring, as natural oils can help protect your scalp.

– Use a color-safe shampoo and conditioner specifically designed for color-treated hair.
– If your kit includes a post-color treatment, use it now.
