I scrub like mad when I co-wash wash my hair normally once or twice a week and the rest of the time I water wash and scrub like mad then detangle with conditioner.
I have super sensitive skin so as for an allergic reaction it is possible but I even used to get it even with shampoo. The only shampoo that doesnt give my the yucky stuff is head and shoulders 2 in 1! The worst shampoo for giving me it is Dove 2 in 1.
There are absolutly no cones, conols or xane's in anything Im using either.
From U.K & started CG 13th July 08
Using VO5 Moisture Milks Passion Fruit Smoothie for co-washing and conditioning.
Using Boots curl creme
Considering going Mod-CG and using H&S once a week to prevent build up, flakes and other nastys.
