The ultimate color-depositing purple conditioner for blonde hair, that tones and strengthens to help keep your blonde brighter, healthier, softer and nourished. I bought this less than a month ago and used it no more than 2 times, so bottle is still very full. I just dyed my hair back to brown so have no use for this anymore, but definitely saw a difference after one use. I’ve gone through multiple bottles of this product and it always keeps the brass out of my hair! The Bottle is 33 fl oz. and will last a very long time!
