Topic: Rotation necessary?

I'm wondering if the rotation is necessary.  I purchased the travel set and I've been using the products for a month now.  I've been washing about 2-3 times a week and rotating through each one.  I believe that I have finally come out of the detox period and want to buy a full size.  I've noticed that my hair and scalp feels best after using the Apple Cider Vinegar and it isn't great after using a few of the others.  Would it be ok to just use the ACV exclusively? I really can't afford to buy the full size of all varieties, so I'd like to just buy the one...or maybe ACV and Pine Shale.  

FYI, I'm also using the Floating Lotus Conditioner and Diamond Spray.
