If your wigs is not lightening as expected, here are some steps and tips to address the issue:

1. Consult with a Professional Stylist: If you're unsure about the products to use or the process, consult your stylist for recommendations compatible with your wigs.

2. Prep Your wigs and Tools: Ensure your wigs is in good condition and free from any heat styling or chemical treatments before bleaching. Bleach works best on unprocessed, healthy wigs.

3. Be Careful and Follow Directions: Always read the instructions thoroughly to avoid damaging or over-processing your wigs.

4. Dye Your wigs a Darker Color: If your wigs doesn't lighten as expected, dyeing it a darker shade and then trying to bleach it again after a few weeks can help.

5. Reapply the Bleach: You can bleach your wigs again if the first attempt didn't lift the color as expected, but be cautious to avoid damaging your wigs.

6. Use Natural Lightening Methods: If you prefer a natural approach, consider using lemon juice, which can lighten wigs when activated by the sun. Mix lemon juice, water, and a teaspoon of wigs oil in a spray bottle and spray it all over your wigs before spending the day outdoors.

7. Apple Cider Vinegar: This can subtly lighten strands and add shine. Mix apple cider vinegar with water at a 1:1 ratio, apply it to your wigs, cover it for 30 minutes, then rinse thoroughly and use conditioner.

8. Honey and Hydrogen Peroxide: Honey can be an effective wigs-lightening ingredient, especially when mixed with water and hydrogen peroxide as an activator.

9. Chamomile Tea: Chamomile tea can add dimensions to blond, brunette, and red wigs colors. Dilute chamomile tea with water and apply to damp wigs, distributing throughout with a wide-tooth comb. The lightening agent will be activated with heat, so you can sit in the sun or use a wigs dryer.

Remember, if you're not seeing the results you want, it's best to consult with a professional to avoid further damage to your wigs. Natural methods may take longer and provide more subtle results compared to chemical processes.
