I have only used it twice so far

I was a bit unsure of this shampoo the first time I used it. I washed my hair twice the first time, and it didn't lather that well. The second lather was much better.
I have been suffering from a dry, flaky scalp for almost all of winter, this shampoo definitely decreased the flakes from the first wash, and the second wash they were almost non existent.
My hair feels incredibly smooth, my scalp feels refreshed. Not itchy, very little flakes. Before I couldn't go a day without washing, as my hair would get greasy, and smelly. I was using a dry shampoo which only made my scalp itchier. With this shampoo, I feel my hair will remain "fresh" longer (I think it's the Salicylic acid in it). So hopefully no more dry shampoo.
I followed with AG Hair cleansing cream the first wash, and my hair felt sooo good. The second wash I followed with Renpure Coconut Cleansing Pudding, which also worked. I just haven't found a conditioner I like yet (I will try the Vichy conditioner in the future).
But I will definitely continue to use, I love the results I have noticed in only two washes. I recommend.
I forgot to mention, the shine! Very shiny, healthy looking hair!
