The first thing I noticed was the scent. It felt fresh and salon-like, which made my wash routine feel more enjoyable.

What I Didn’t Love
I did notice that this shampoo may not be the best choice if my hair is already very dry or damaged. On some days, it felt like it cleaned a little too well, so I had to follow up with a good conditioner or mask. I also felt that results were better for adding body than for deeply moisturizing hair.
