I am a Phyto convert and am now addicted!! I live near Tahoe and we also get the cold, dry air with lots of sun to boot. Amazing for my hair in terms of results.
I've used Aveda Sap Moss for over a year now, (I love the smell) but I used to use Pantene Pro B for dry hair. I'm probably going to go back to that. Every time I read Allure or other magazines, Pantene gets rave reviews.
