I read the reviews and tried it out, but I didn't feel it was very smooth and moisturizing. The scent was like essential oil, but it was a unique smell.
I received this as a gift from Suzykirei. It made my hair smooth and I really enjoyed using it. I was looking for a shampoo that the whole family could use, so the fact that it didn't have a strong scent was a plus. However, considering the cost-effectiveness, I wasn't sure if I would buy it.
I learned about Electron at the salon I used to go to and now I use the booster, but I love it so much that I wanted to try the shampoo too, so I bought a trial size! It makes my hair super smooth and I love it! I'm thinking about buying the larger size too^^
It lathers well! I have waist-length hair, and the amount was enough! The scent is unisex, which is my impression. I'll try the single-use size a few more times, and if it's good, I'll buy the regular size.
I think this scent would be popular with people who like Aesop. I like it because it doesn't make my hair feel rough even on dry hair and the scent doesn't linger too strongly.
