In my opinion, I think if someone uses Surge daily, they should wash their hair daily. When you say Surge I'm assuming the Revitalizer Plus 14... right? Well, that's the only product of the Surge line that I have. /images/graemlins/smile.gif
When I start doing wash 'n gos for my hair, I'm going to start using Surge more consistently and wash/rinse my hair daily with water. Surge is a leave-in in itself but I just use it for my scalp. After washing, I will put leave-ins and a moisturizer on my hair just like with any other wash.
I tried using Surge just on my scalp when my hair was dry and it just doesn't look right. It will make your roots curl up while the rest of your hair is straight. So I just use Surge whenever my hair is wet.
Hope that helps! /images/graemlins/wink.gif
