I use it about twice a month to Close/Seal Cuticle after DC'ing with Heat to lower Ph Balance and to balance out my porosity.
Even though I DC with Heat regularly, I've cut down on the amount of ACV Rinses I do now to twice a month.
I use a Pre-Mix too. Right now I'm using Koils By Nature's ACV Rinse. I also love, love, love Hairveda's ACV Rinse and I also use one by BlueRoze Beauty.
