I received a sample at a drugstore, so I gave it a try. After a bath, I applied it to my towel-dried hair, starting with the ends. When I dried it with a hair dryer, my hair felt smooth and silky. The scent wasn't too strong, so it was easy to use and could be used on dry hair, which was convenient. I was very satisfied because my hair was still manageable the next morning.
I don't like after-bath treatments, so perhaps because I use them on dry hair in the morning, my hair is already severely damaged, so it doesn't make it smooth. I usually use the moisturizing type to make it shiny, but this was the first time I tried it. The moisturizing type also comes in a fragrance-free version, but I wonder if this one doesn't? I use a lot, so I feel like the fragrance is too strong, so I end up mixing it with the fragrance-free moisturizing type. It might be better to use a small amount as a regular after-bath treatment.
Like the morning mist, this is an item I keep repurchasing. It's moisturizing, easy to apply to hair, and seems to protect it from the heat of a hair dryer. When I wake up in the morning, my hair feels so much smoother with and without it, so it's become an item I can't live without. I also love the scent.
It has a very feminine, lovely scent that lasts. I was so impressed with the sample I received that I wanted to try more, so I bought a small one. It leaves my hair smooth and not sticky. I have a lot of hair, and I've been trying out a lot of different products, but this is the first time I've used it in a while! If it continues to work, I'll give it 7 stars.
I received a sample and used it once (^o^) I apply hair milk to wet hair, let it dry a little, then apply oil to the ends, and my hair becomes smooth after it dries! (Of course, it's not just the oil that makes it so great^^;) The scent isn't too strong, it's good value for money (1,100 yen for the small size), and it's made in Japan, so I think it's safe to use (^^) I'm excited to try the real thing!
