While on a business trip, I was offered a shampoo rental service, so I tried using it twice a day, morning and night. According to the official website, the moisturizing and hair repair ingredients "transform dry hair into moist, shiny hair." To cut straight to the point, I gave the shampoo a one-star rating and the treatment a five-star rating, ultimately giving it three stars. My hair is very coarse, thick, and dry from bleaching and monthly gray dyeing. The shampoo smells great, but it was very rough and difficult to rinse out. However, I didn't experience any itching or dandruff, so I felt like my scalp and hair were thoroughly cleansed. The treatment left my dry hair smooth and silky. However, I still noticed dryness in the ends and overall frizz the next day, so I'm not sure if I'd buy the actual product. I used it during the dry winter months. It has a gorgeous, soft neroli and peony scent.
