it does take time for your hair to adjust to COwashing with condish , about 2-3 weeks to get use to it..just be patient and wait it out , eventually your curls will spring back..also i have used jessicurls and love her products , not sure on the other products u mentioned but im sure other curlis have had great success with devas. im a wavy and doing CG has brought curls that i didnt know i had =)
Modified CG-Use Low Poo
Use Suaves & VO5 Condish For CG-Honey+ Condish=My curls are loving it!
