Do you have the link to the vid?
I have done conditioner only before with success. I've been experimenting with products lately so I haven't done it in a while. I haven't tried it in the winter though. If I remember correctly, for second day hair I would spritz my hair with water and scrunch in some conditioner and this worked for me.
I just got my jug of Kenra conditioner in so I will try it with this conditioner. The one that worked before was tressemme naturals.
I'll tell you I was floored that conditioner only even worked for me and it wasnt fussy...and my hair looked great.
