Stylists✨ Here are some quick tips for highlighting coils. No overlap. Overlap causes breakage & curl stretching. Try not to overlap over any pieces through the ends that have been previously lightened. Buffering Lightener like @oligopro Blacklight Cream. Which I used w/10vol. @fastfoils for Efficiency. They distribute heat evenly throughout the foil allowing things to process 25% faster with lower volume developer.
