This is pretty good, but I find that i need to leave it in much longer than what is recommended on the bottle for it to be effective. I don't really like the smell very much either.
This is a good alternative though, if you want something that is less drying than the shampoo.
My hair had become SUPER brassy and orange-toned. I've used this only once so far and it made a HUGE difference. Got rid of all the brass and made it look like I'd got a touch up at the salon. It also didn't dry out my hair at all. Definitely recommend! I'm keen to continue using it.
