most conditioner use it. shampoo too (panthene pro-v, garnier fructis) look fo dry hair shampoo and conditionner.
I use normal hair shampoo and I see the difference in 2 day if I change shampoo.
Panthene make my hair extremely silky, garnier fructis make them silky but less.
I will try on my system when I decide. but I think using shampoo each day will protect them better with silicon (well not any shampoo), its the case with my real hair. and for people who color their hair. and hair systeme hair is the same a colored hair (cuticle removal).

Im still hesitating... my hair are now 14 inch long lol. I would like to see a toplace system with long hair but everybody has short hair here haha.
