Most of us at Gemmist color our hair too! Our products are formulated with ingredients that are known to help protect dyed hair from being stripped of color as you shampoo and condition. Sulfate-free cleansing agents and amino acids are two color-protecting ingredients that we trust to keep our color radiant. If you are still having issues, contact our Customer Support team at support@gemmist.com.Support Hours:Mon-Fri: 10am-5pm PST
