Really no need for any overpriced "hairpiece specific" shampoo/conditioner.Any sulfate-free shampoo will do.Many here,myself included use L'oreal EverPure color care line and it seems to be gentle enough for system hair.

You can pick it up at any Walgreens or CVS for around $7. Another option is Johnson's baby shampoo which I also use ocassionally.A good leave-in condidtioner is also recommended,preferably one with sunscreen.I use this one http://www.adventhair.com/1001.html
