Good but you need way more

I’m seeing a big difference on my frizzy hair BUT I am using waaaaaaay more than the recommended amount. About 10p sized amount for my long hair but it really works and my hair is shiny and much less frizz.

Good oil for less frizz

I have been through 3 of these bottles, each one last me about 6 months with me using it every day, I have curly hair so I use this product to crunch out my gel cast when my hair is dry to eliminate frizz

Best Oil out there!

First off, the packaging is sleek and minimal, which I appreciate. The applicator makes it easy to control the amount of product you use, preventing wastage. In terms of texture, the oil is lightweight and absorbs quickly into the hair without leaving a greasy residue. A little goes a long way, so even with a small amount, I found it instantly added softness and shine to my hair. Additionally, I love that it’s formulated with nourishing ingredients that promote long-term hair health. It contains a unique blend of oils and works to strengthen and protect hair from damage, which is essential if you frequently style your hair, especially with heat. It also protects up to 450 degrees! While the price point is on the higher side, I believe the quality justifies the cost. Overall, I would highly recommend Olaplex Oil for anyone looking to boost their hair care routine. It delivers on its promises, and I’m definitely seeing a positive difference in my hair!

Great Oil!

I have been using this oil for a long time and I absolutely love it!! My hair is very dry and damaged so using this oil is a MUST. A little goes a long way, I just use a few drops. I personally like to use it on dry hair and concentrate it on my ends. I love the packaging it’s compact so its great to take with you on a trip. I also like that the bottle is clear so you can see how much product is left. The oil also has a pleasant smell which is great because I straighten my hair and the oil’s fragrance can hide the smell of burning hair. (Lol) overall, it is a great oil to add hydration to your hair, additional shine, and protection! Sometimes I even use the teeniest amount to tame my frizz.

Great on colored fine hair

I’ve been using this for over a year (one drop mixed with #6) every wash and I still have almost a full bottle. A little goes a long way.

Good for all hair types

I used this Olaplex bonding oil mostly when my hair is dry. I like to see the oil soaking into my hair and watching the oil refresh my dead ends. It makes my hair so shiny and soft as it is very long. I get compliments all the time on how pretty my hair is. I now can thank Olaplex bonding oil for bringing back the shine. The scent is refreshing reminds me of a light citrus smell.The container is glass and would be easier to dispense if it had another way to pour out.I can shake it easily but would be easier to handle with another top . I can use just a few drops on each side to make sure I work thru all of the bonding oil.I like that my dry damaged hair is more tame and managed and easy to comb thru. It also is a heat protectant , it strengthens and repairs all hair types and does not feel like it leaves a residue. I like Olaplex and will continue to use on my hair.

Super moisture

My holy grail hair oil!! I usually wear my hair curly, so you would never realize how dry my ends were. I started wearing my hair straight, and MY GOD. I’ve been using this, and my hair is literally so moisturized

Awesome results!

I wanted to express my satisfaction with the olaplex bonding oil #7 Not only does the product leave my hair soft, but it also gives it a very healthy and shiny look. I love it and will definitely be jeeping usin it! Thank you for providing such a high quality product that delivers on its promises. I look forward to continuing to use this product! I love it, it smells nice but it's not overpowering, it's a subtle scent and it does its job. My hair immediately feels softer and looks shinier after using it on dry hair and it's also great for my heat protection blow-drys. A little goes a long way! I highly recommend it.

Shiny and Smooth Hair

I've used a few Olaplex products in the past and have always been very happy with my hair afterwards. Once I saw they made this bonding oil, I knew it was something I had to try! First of all, I enjoy the scent of this product. It's lovely, clean, and not overwhelming like other hair oils I have tried. I like to add it to my hair before styling with my straightener or curling iron since it protects from heat. Also, it has truly helped with controlling my frizzy hair so I have been using it daily, whether styling my hair or not. It leaves my hair looking and feeling shiny and smooth. I've received so many compliments on my hair and how great it looks since using. I know it's another Olaplex product that will be a staple in my hair routine! I highly recommend this product!

Love this !

I’ve been a fan of Olaplex for a while, but I finally tried the Nº.7 Bonding Oil, and I’m so glad I did! It’s become my go-to finishing product after straightening my hair. It adds a beautiful shine, smooths everything out, and helps control any flyaways. My hair feels incredibly soft, and I’ve noticed less frizz, even in humid weather. I love that it also protects from heat up to 450°F, which gives me peace of mind when styling. Plus, it’s lightweight, so it doesn’t weigh my hair down or make it greasy. Overall, this oil is a game-changer and a must-have for anyone looking to boost shine, repair damage, and keep their hair looking healthy and sleek
