Cones stick in your hair and don't let moisture get in. Which causes frizz and greasyness and a lot of damage in the long run. Personally It's a 10 always did me well. When I used to straighten & blow dry that's what I used and it kept my hair healthy and manageable. They're amazing products. But I'd never use them while on the CG method. But if they ever come out with a silicone free anything I will be the first in line to buy. HIH
