I've used both for a year, and it ran out this summer with use every day to every other day showering with it. I have to be honest and say that I regret the purchase so much. I had another shampoo that helped me for a long time instead of ruining me over time. I've lost so much hair, and this combo has neither prevented nor helped with my hair, I've lost so much that it's noticeable, and therefore there will be no more use of this, instead, I'm going for a hair transplant. Very disappointed as the hope was high, but then maybe I also had bad luck... However, it doesn't itch like it did before, which gives it my extra star, but dandruff/dry scalp is present. I'm 1% of the dissatisfied, but if you have bad luck like me, don't buy this.
