The No. 7 Bonding Oil is the newest addition to the Olaplex line. This is a lightweight, concentrated oil that claims to increase softness, shine and manageability, repairs damaged hair, strengthens and protects hair structure and improves color vibrancy while minimizing frizz. It also provides heat protection up to 450 degrees.
Ingredients: Dimethicone, Isohexadecane, C13-14 Isoparaffin, Coco-Caprylate, Phenyl Trimethicone, Bis-Aminopropyl Diglycol Dimaleate, Propanediol, Zea Mays (Corn) Oil, Beta-Carotene, Helianthus Annuus (Sunflower) Seed Oil, Moringa Oleifera Seed Oil, Punica Granatum Seed Oil, Water (Aqua), Morinda Citrifolia Fruit Powder, Fragrance (Parfum), Hexyl Cinnamal, Eclipta Prostrata Extract, Ethylhexyl Methoxycinnamate, Limonene, Tocopherol, Citral, Linalool, Melia Azadirachta Leaf Extract, Citronellol, Pseudozyma Epicola/Camellia Sinensis Seed (Green Tea) Oil Ferment Extract Filtrate.
The first ingredient is dimethicone which, from what I’ve read on different sites, is a cheaper silicone that is not water soluble and is hard to remove. However, Olaplex says they use a high quality, low molecular weight, water soluble dimethicone that easily washes away and does not build up in the hair. I was surprised to see corn oil listed, as this is not an oil I think of for use on hair, but corn oil prevents dryness by locking in the hair’s moisture. It contains vitamins K and E and omegas 3, 6 and 9. In addition to other oils, this has propandiol, a conditioning humectant. The Bonding Oil also contains Olaplex’s bond builder that helps repair disulfide bonds that are broken down during a chemical service.
Directions state to tip the bottle upside down and tap on the bottom to dispense a few drops to damp or dry hair. This can be mixed into the No. 6 styling cream (or leave-in conditioner or other styling aid) and/or applied after using Olaplex’s new No. 8 moisture mask.
As a side note, I’ve been using silicone-free products in my fine hair for about a year mainly because, if I use a silicone-containing conditioner, the silicone seals moisture in the hair, but doesn’t allow other treatments to penetrate the silicone (apparently), so anything I put on my hair after using that conditioner would be useless I gather. Over the last few months my hair has gotten so dry and looks quite damaged despite my best efforts (though I do need a haircut; I haven’t gotten anything done with my hair for about 8 months). I’ve also had breakage. I’ve been thinking about adding silicone back to my hair and thought this bonding oil would be a good place to start.
The oil is easy to get out of the bottle. It has a light scent that doesn’t really linger. This feels like a dry oil that is not heavy. Above, I rubbed it on my arm for a couple seconds and it doesn’t leave an oily residue, but leaves a smooth-feeling sheen.
Above, in the before photo, I air dried my hair and combed through it a bit, then added about 8 drops for the after photo. There is an immediate smooth feeling to the hair (due to the dimethicone) and it looks a bit less frizzy and less poofy with a bit of shine.
The before photo above was after using a clarifying shampoo and moisturizing treatment and after, 8 drops of the Olaplex oil. Again, the hair feels smoother in the after photo. It’s harder to see results on this curlier hair.
I’ve used the oil on towel dried hair as well to see if the hair detangles with a wide tooth comb and the Bonding Oil on it own. It’s better than combing with wet hair and no product, but using a leave-in conditioner detangles and combs through better.
My flat iron glides through the hair much nicer and with less friction with the application of the oil.
I wash my hair about every 5 to 6 days and can use the Bonding Oil morning and night with no buildup or heaviness on the hair between wash days.
Again, my hair is quite dry, damaged and poofy and my hair seems to absorb this quite fast, so there aren’t really amazing visible results in the photos (of course, I haven’t been using this for long). I can only assume that the hair is getting repaired from the inside due to the bond repair technology. My 4-inch grown out hair with no color feels better than my colored hair with the Olaplex use.
I’ve used the oil for about 3 weeks, morning and evening, and my hair is softer and more manageable. I apply after using a leave-in conditioner and/or heavier hair oils on towel dried hair to seal in moisture. I’ve been getting breakage at the back, underside layers of my hair when I wash it and I think, with the use of the Olaplex, there is less breakage.
I’ll try and update the photos here after I get my hair cut and colored in a couple weeks to see if there is a more visible difference using the No. 7 oil after I get a few of those dry, damaged inches off my hair.
Update (October 26, 2019):
The above photos are a couple weeks after a color, cut and keratin straightening treatment. For the first photo I blow dried my hair and applied Olaplex No. 7 after. The second and third photos are air dried hair with the after photos showing application of the hair oil. The hair looks smoother with less fly-aways and a more “finished” look.
I like that the Olaplex No. 7 Bonding Oil creates an immediate smoothness and softness on the hair and I can feel results rather than see a dramatic difference at this point. My hair might be too dry and damaged and this product is so light, I feel like I could use a lot of this oil before my hair would actually feel moisturized. I’ll likely continue to purchase for the bonding technology, heat protection and smooth feeling on the hair as a nice last step in my hair routine to seal moisture in. Time will tell if there is long term improvement.
Thank you for reading.
