Shampoo/Cond. Extensions

Can someone please recommend some great hair products for hair extensions? I feel like the extensions aren't as soft and shiny like before. The stylist said to use my current hair products,which is Nexxus and sold me some Red conditioner for color maintainance from Biologe to use periodically. (When using that, my hair seems less tangled) I have been using a Nexxus wash out conditioner, plus a leave in detangler, am I over conditioning the extensions? What is the appropriate way to condition them? Last question, do you use a frizz or shine gloss on your hair? I read that you should stay away from products with silicone in them. Please advise, I would love your opinions!!!Flaca2006-08-24 20:36:44
