I tried it when I was traveling. It's hard to tell because my hair isn't as frizzy at this time of year, but it felt just right.
I feel like my hair is in better condition when I alternate between the two shampoos, so I bought a second one. It definitely leaves my hair feeling more moisturized than my usual Essential shampoo. I use only this shampoo series, and combine it with a treatment from another brand I have at home, but I could feel a difference even with just the shampoo. However, the price is a little high, so I'm not sure if I'll buy it again.
It smells great and makes my hair smooth and manageable! I wish they would make refills for the treatment too!
While using this, my hair's curls and waves were calmed down, and it stayed so straight that I didn't even need to use an iron. I highly recommend it to anyone who is concerned about wavy hair! The only thing I was a little disappointed about was the cost-effectiveness, as the 350ml shampoo ran out quickly.
It suits my hair type, doesn't dry it out, and leaves my hair smooth all the way to the ends. It also has a nice scent, so I've bought it twice now.
