Adding highlights to a curly human wig can enhance its appearance and give it a more dynamic look. Here’s a step-by-step guide to help you achieve salon-quality highlights at home:

1. Choose the Highlighting Technique
There are several techniques to add highlights to a curly human wig:
- Balayage: This technique involves painting highlights onto the hair with a sweeping motion to create a gradient effect from the roots to the tips. It’s ideal for a natural, sun-kissed look.
- Foil Highlights: This method involves separating small sections of hair, applying color, and wrapping them in foil to intensify the color. It’s great for achieving bold, vibrant highlights.
- Ombre: This technique creates a gradient effect where the color transition starts subtly at the roots and becomes more pronounced towards the ends.

2. Prepare Your Workspace and Tools
- Place the wig on a wig stand or mannequin head for stability.
- Gather all necessary tools: hair clips, highlighting color, developer, mixing bowl, brush, foil sheets or plastic wrap, and gloves.

3. Section the Hair
- Divide the wig into manageable sections using hair clips. Determine where you want to place the highlights, such as around the face, through the crown, or at the ends for an ombre effect.

4. Mix the Highlighting Color
- In a mixing bowl, combine the highlighting color and developer according to the manufacturer’s instructions. Stir until the mixture is smooth.

5. Apply the Highlights
- Unclip one section of hair and comb it smooth. Apply the highlight color using a brush, starting a couple of inches away from the roots for a natural look.
- If using foil highlights, place a foil sheet under the highlighted section, fold it over the hair, and secure it.
- Repeat for all sections you want to highlight.

6. Allow to Process
- Follow the processing time specified in the product instructions (usually 20 to 45 minutes). Cover the wig with plastic wrap or a shower cap to keep the highlights moist.
- Check the color development periodically. If the desired color is not achieved, let it process for a little longer.

7. Rinse and Condition
- Rinse the highlighted sections thoroughly with lukewarm water until the water runs clear.
- Apply a high-quality wig conditioner to restore moisture and soften the strands.
- Rinse out the conditioner and gently pat the wig dry with a towel.

8. Style as Desired
- Once the highlights are applied and the wig is conditioned, style it as you normally would.

Tips for Success
- Placement Matters: Strategically place highlights where the sun would naturally hit the hair for a natural look.
- Gradual Transition: Ensure a gradual transition from the base color to the highlight color, especially for balayage and ombre techniques.
- Consult a Professional: If you’re unsure about color selection or technique, consulting a professional colorist can provide expert guidance.

By following these steps and tips, you can add beautiful highlights to your curly human wig and achieve a stunning, personalized look.
