What it is
Moisturize your hair from the inside out for shiny hair all day long. Plant-derived amino acid "Pericea" derived from palm, sugarcane, and cassava, repair ingredients like "Protecute" keratin, which is the same size as the keratin found in hair, and moisturizing ingredient "Lipidure NA" tightly lock in the plant-based beauty ingredients that penetrate, leaving hair with sustained moisture and a smooth texture. Olive squalane and starch-derived rutin derivatives also protect hair from everyday sunlight and the heat of a hair dryer. *Packaging may change without notice.

I can't live without my hair milk and oil after using it, but because my hair is thin, heavy products make it look sticky, and products that are too light make it tangle, so I've been trying out different hair milks to find the perfect one. This hair milk is light and blends easily into my hair, and even if I use a lot, it doesn't look sticky. My hair tends to tangle easily with just this, so I add oil, and the rose scent is so lovely and soothing. I feel like my hair stays more manageable after blow-drying.
I'm currently using the scalp care shampoo and treatment from the same series, so I was curious about this one too and bought it. It has a lovely, subtle rose scent. It's a generous portion and easy to use. It leaves my hair silky smooth, and above all, silky smooth. I wanted a little more shine, and I felt like this alone wasn't enough moisturizing, so I mixed in half a pump of Aujua Inmetrie Oil. (This is my own judgment, so I'm not sure if this is recommended.) It was just right. I wanted volume without irritation, so this was great. I'm holding off on repurchasing it, as I'd like to find a single product that gives me both shine and volume (compared to my own). Personally, I feel confident with Of Cosmetics' products.
After towel drying, I pump two pumps into both hands, spread it evenly, and apply it from the ends upwards. The gentle rose scent seems to have almost disappeared after using a hair dryer. (This may vary from person to person.) I like how it gives my hair shine and manageability.
The appeal of this product is that it doesn't leave my hair sticky, even the next day, and it makes my hair smoother. However, it's not the best value for money... I'm worried about whether I'll be able to continue using it.
The rose scent is soothing and the texture is just right.
