How to Use:

1. Preparation:

   • Wear suitable gloves to protect your hands.
   • Mix Streax Professional Developer 40 Volume 12% with the chosen Streax Professional hair color product in a non-metallic bowl. Follow the mixing ratio specified in the hair color instructions (usually 1:1 or 1:2, depending on the product and desired result).

2. Application:

   • Apply the mixture to dry, unwashed hair using a brush for precise application.
   • Ensure even distribution to avoid patchy results.
   • Start at the roots, where the color needs the longest processing time, then apply to the mid-lengths and ends.

3. Development Time:

   • Allow the color to develop for the time specified in the hair color instructions. This is usually between 30 to 45 minutes.
   • Check the development regularly to ensure the desired color result.

4. Rinsing:

   • Once the development time is complete, rinse the hair thoroughly with warm water until the water runs clear.
   • Follow with a post-color treatment or conditioner to lock in color and add shine.
