If hair oil sounds suspiciously like snake oil to you, we've found the product that will turn you on to the trend: OI/ OIL. It's a hard-working potion that improves your hair for the short- and long-term. First, this lightweight serum instantly tames frizz (thanks to protective silicone), providing the ultimate finishing touch for any hairstyle. To strengthen your mane over time, it comes packed with antioxidant-rich roucou oil that helps prevent hair aging and breakage.
I've never heard of roucou oil, but i'm all about it now. I might end up buying the full size bottle. I was always using other oils on my hair and it was great, but this one tops it. I love how light it is on my hair and I've read that it's got natural sun protection. It also helps hair grow. This is perfect for my lifestyle and a great addition to my daily hair routine.5
This product is the best sample I have received from all my Birchbox boxes. I cannot get enough of this. Every time I walk by the bathroom I need to apply a little bit on my hair. It is the perfect smell, perfect texture and all. My hair has honestly changed because of this amazing oil.5
this stuff makes your hair ULTRA soft and silky. just a few drops is enough for a full head of hair. it does not weigh your hair down or make it greasy. also, it smells like heaven!5
This is absolutely one of the best hair products I have ever used. I received it as a sample, and just keep buying. It makes my hair so smooth and so soft. My hair is wavy, but I often straighten it. Regardless if I let it air dry, blow it out, straighten it, or curl it, my hair is smooth, soft, and shiny and fly aways are limited - and it never looks greasy, which can be a concern serums. It also smells absolutely fantastic. I use it every day, and my boyfriend even uses it on his beard. If I don't use it, I actually notice a difference in my hair. I really don't see myself ever not using this and not keeping it stocked!5
It smells amazing! I went to the website to purchase the full size bottle because it was so good. It's not heavy and greasy. It's light, refreshing, and moisturizing. It's a must have.5
I was hesitant about putting oily on my self-described "combination" hair. However, this did not make my hair greasy at all. I apply 1-2 pumps to my longish hair and am left with a luscious, manageable mane. It made my hair really soft and smooth - plus it untangled my knots. I thought the smell was fine... but, I could see how people could be put off by it. It smells kind of like baby oil. All in all, I'll probably end up shelling out for this product once my sample runs out.5
This product really smoothed my hair but it had a very masculine scent. I did use most of the bottle.3
This is my favorite Birchbox product I've gotten so far. I need to use 5 pumps, because my hair is long and thick. I get such nice results. I even use one pump in my son's hair occasionally! His hair is thick and super curly and this product is perfect for his hair texture, haha.5
I use this product on my hair, skin, etc. and I absolutely love it. Great product Birchbox!!!! It does not leave your hair oily or a film on it and smells great.5
I have dry and thin/flat hair. This gave me the perfect balance of moisture without weighing my hair down4
