First of all, the packaging is stylish, which lifts your spirits even before you use it. The aqua white floral scent is also elegant, and I love how it soothes while caring for your hair. The contents are thick like a cream, but when you apply it to your hair, it spreads smoothly and doesn't make it feel heavy, which is great. After rinsing, my hair is moisturized all the way to the ends, and is smooth to run my fingers through. It seems particularly well-suited for hair that tends to get frizzy due to dryness or static electricity. It has a special care feel, but the finish is easy to manage, so I think it's a serum mask that you'll want to use regularly.
My hair gets dry and frizzy... This product leaves it smooth and moisturized after washing. I can't go to the salon often, so I'm happy to be able to take good care of my hair at home. It's also great value for money as it comes in a large capacity.
It is smooth to use without being sticky and leaves your skin moisturized.
I was concerned about dryness and frizz after repeated coloring and perming, so I tried this with high expectations. It was thicker and richer than I expected, and honestly, I thought it might be a little heavy, but for highly damaged hair, it was just right. It calmed my hair, like each strand was saturated with moisture, and it became moisturized and easier to manage. It makes even frizzy hair easier to manage, so I think it's a very reliable hair mask for people who are concerned about dryness and damage.
This hair mask is packed with rich beauty serum and is gentle on the hair. After use, hair is left moisturized and smooth to the touch. It provides thorough care for dry and damaged hair, and I felt that incorporating it into my daily hair care routine would help to improve hair's moisture and shine.
