Achieving bold hair colors like Lady Gaga and Billie Eilish requires some planning, patience, and professional help. Here’s a step-by-step guide to help you get started:

*Pre-Coloring Prep*

1. *Consult a professional*: Bold hair colors require expertise, so consult a professional stylist who has experience with vibrant colors.

2. *Check your hair’s condition*: Bold colors work best on healthy hair. If your hair is damaged, consider getting a trim or using a hair mask before coloring.

3. *Choose the right shade*: Consider your skin tone, eye color, and personal style when selecting a bold hair color.

*Coloring Process*

1. *Bleach or lighten*: To achieve bold colors, you may need to bleach or lighten your hair first. This step can be damaging, so be sure to follow up with a nourishing treatment.

2. *Tone and color*: Once your hair is lightened, your stylist will apply a toner to achieve the desired shade. For bold colors like green, they may use a semi-permanent or demi-permanent dye.

3. *Seal the color*: To lock in the color and moisture, your stylist may apply a color-sealing treatment.

*Maintenance and Aftercare*

1. *Use color-protecting products*: To maintain the color and vibrancy, use shampoos, conditioners, and masks specifically formulated for colored hair.

2. *Avoid heat styling*: Heat styling can cause color fade, so try to minimize your use of heat tools or use a heat protectant spray.

3. *Touch-ups*: To keep your bold color looking fresh, schedule regular touch-ups with your stylist.
