Carefully selected moisturizing ingredients penetrate deep into the hair, leaving it smooth, silky, and easy to run your fingers through. Formulated with heat repair ingredients (γ-docosalactone), which improves repair power when heat is applied, and meadowfoam estolide, which moisturizes each strand of hair and leaves it supple. The texture has also been improved to blend more easily with hair, improving repair power and shine. <Recommended for> . Those with thin, tangled hair . Those concerned about dryness . Those who prefer airy styling .

I used it in combination with the shampoo from the same series. The finish was light, but it didn't make my hair too dry, even in areas with very dry or cold weather, so I think it does provide a certain level of moisture. There is a sufficient amount, so I think it will be sufficient for people with normal long hair.
I was looking for a treatment and found a trial size, so I bought it! After using it, my hair feels smooth and manageable. The 1000ml bottle costs about 2000 yen, so I'd like to refill it and buy the larger size.
My hair is so smooth! I used to buy the smaller size at the drugstore, but when I found out that the full-sized version was available, I bought it right away. I've also tried salon-exclusive products, but this is the best so far.
It's amazing! I gave it to a friend as a small gift and it was well received. I think I'll buy the regular size next time.
I bought the trial size. I'm grateful that it's portable. I use up the shampoo faster at home, so I only bought the treatment to adjust the amount. I also wanted to try the shampoo.
