Description
BRONSUN Developer 3% is a professional oxidant for use with compatible BRONSUN dyes, following the instructions for the specific dye system. Use the manufacturer’s prescribed mixing ratio and application protocol; do not substitute an unrelated tint oxidant or henna fixer.
Professional use only.
Why does the developer matter as much as the brow dye?
Amy’s Educator’s Note: Brow colour isn’t created by the dye tube alone: the correct developer helps the colour develop as intended. Changing oxidants to save a step can change the result and introduces avoidable uncertainty. My tip: set up a dedicated, clearly labelled BRONSUN mixing station and confirm the ratio for the exact formula you’re using before every treatment. A consistent formula gives you a reliable starting point when troubleshooting colour.
Pair with BRONSUN Brown Hybrid Gel Dye #6.
