1. Use professional  Shampoo: Over the counter shampoo  can strip color, so opt for a gentle, professional recommended shampoo specifically designed for color-treated hair.

2. Condition Regularly: Use a deep conditioner or a color-protecting conditioner to keep your hair moisturized and prevent the color from fading.

3. Limit Washing: Try to wash your hair less frequently, ideally 2-3 times a week, to prevent color from washing out.

4 Cool Water Rinse: Use cool or lukewarm water when rinsing your hair. Hot water can open the hair cuticle, causing the color to fade faster.

5. UV Protection: Protect your hair from the sun by wearing a hat or using hair products with UV filters to prevent highlights from becoming brassy.

6. Avoid Heat Styling: Excessive heat can damage your hair and cause your highlights to fade. If you must use heat tools, apply a heat protectant spray beforehand.

7. Use Color-Enhancing Products: Consider using shampoos or conditioners designed to enhance and refresh your hair color.

8. Schedule Regular Touch-Ups: Depending on your hair growth and the type of highlights, regular touch-ups at the salon can help maintain their appearance.

By following these steps, you can extend the life of your highlights and keep them vibrant for longer.
