Had to use a lot, and leave in for longer

Okay I love this stuff overall because my fine blonde hair looks very greasy very easily and this product never did that to me. It kind of did the opposite; I didn\’t even notice an effect unless I left it in for a WHILE (~30 mins) before rinsing it out. But, when I did that my hair looked amaaaaaaazing. For the crazy price though I would not buy it again. But if you can afford it go for it.
