I dont know all the science behind it... but I had used coconut oil on my hair...and my hair was a diaster!!... I used the cleansing shampoo...and it did remove the oil/product build up....if you already have it...give it a try...see how your hair feels...maybe you'll need a couple of uses....to remove it all...
