This is an all-in-one product that can be used as both a shampoo and a treatment, as it contains treatment ingredients. While using this product, I did not need to use a separate conditioner or treatment. Even after washing and drying my hair, my hair felt calm and smooth. For a product from Rienne, it had very little herbal scent, just a faint floral aroma.

At first, I saw that it was labeled as a treatment, so after shampooing, I absentmindedly applied it to my hair, but the lather was... incredibly abundant?? I was surprised, and even after re-reading the product name, it still said 'treatment', so I felt the inconvenience of having to rinse my hair again like I would with a shampoo. Upon further research, I found that it is marketed as a dual-use shampoo and treatment. Typically, when we think of a treatment, we think of a hair nourishing product used after shampooing, but this product is closer to a shampoo in terms of its formulation and usage, so the product name is a bit confusing.

The scent was pleasant, and the lather was abundant. Even though I have an oily scalp, the oil did not return until late afternoon. The cleansing power seemed quite effective.

I personally enjoy the herbal fragrance, but those who dislike it may find it too strong. Additionally, the price seems high relative to the quantity, and I was unaware of any undesirable ingredients, so I likely won't repurchase.
