What it is
A silicone-free hair oil that creates a moderate weight while suppressing hair spread, leading to neat and shiny hair. The smooth texture spreads the oil evenly throughout the hair, and it is easy to use regardless of hair type or length. It is a pump type that is easy to grab even when you are busy. Recommended for those who want to finish their hair shiny and supple, or are concerned about hair spread, dryness, and damage, silicone-free and synthetic fragrance-free styling base. Contains rice bran oil that protects against dryness and heat damage caused by UV rays and suppresses spread and dryness caused by bleaching and hair coloring, and camellia seed oil that gives hair shine and moisture and protects it. It is also particular about the feel when styling and the feeling that it is easy to blend into the hair, and it can be quickly washed off with shampoo. The unisex package has a simple yet stylish atmosphere that blends in with the interior. <Scent> A woody citrus scent that blends fresh fruit and the freshness of the forest. Based on the fresh citrus of orange and bergamot, it is blended with rich woody notes of Siberian fir and cedar, and accented with spices such as vetiver and clove. The scent of natural essential oils will help you relax while styling your hair.

This is really good! I have a bob, and one pump gives it a moist, manageable shape with a natural shine and a natural finish. 1.5 pumps gives it a firm hold and a nice shine. The shine isn't oily, it's just beautiful. It makes my hair look beautiful. I also really like the scent. The only disappointing thing is that the scent doesn't last long. I love Osaji and bought the treatment oil first, and it was so good that I bought this too, and it's really good. I'll definitely be buying it again.
I bought this because I wanted a styling oil. Osaji is a brand I personally like for its natural feel. This was my first time buying oil, and like everyone else said, the bottle is so big I wondered if it was really 100ml. I applied two pumps to a short bob and rubbed it all over, which left my hair feeling just moisturized, but not messy, and it was great for styling. The scent is a refreshing herbal scent reminiscent of craft cola. It's a shame that it fades so quickly. I like it, so I'm going to keep using it for a while! I only use two pumps, so it feels like it will never run out, lol
I've been thinking about buying it since it was released, and finally I did. As everyone says, it's only 100ml!? It's so big! Lol. The scent isn't artificial, but a lovely essential oil scent! I bought it because it's silicone-free and won't interfere with shampooing, and it certainly lathers up just as well as usual (but you should still pre-wash thoroughly). However, it was heavier than I expected, which wasn't to my liking. It doesn't dry my hair easily... It does contain silicone, but the Pro Style Oil leaves my hair feeling smooth, so I'll go back to that.
When I was no longer a big fan of hair oil, I was searching for a different brand to try (Davines, L'Occitane, John Masters) and ended up buying OSAJI oil, which had good reviews. This is a review after two weeks. I thought the oil would be thick and heavy, but it spreads easily. The scent is woody citrus and not a cheap aroma. It smells nice when you apply it, but it doesn't last very long. L'Occitane's scent lasted quite a while, so it's not comparable, but it still smells good. For long hair, just 3-4 pumps will give you smooth, shiny hair. It keeps your hair moisturized all the way to the ends! It's a large capacity, so it's great value for money.
