Let’s get one thing straight: I’ve tried every hair oil under the sun. From drugstore argan blends to luxe salon serums, my bathroom cabinet looks like a beauty aisle exploded. And yet… my hair still screamed “fried ends, frizz party, dull and dry.”
That was until I found Olaplex No. 7 Bonding Oil—a product so tiny you might think it’s sample-sized. But don’t let its size fool you—this little bottle packs a serious punch.
Whether you’ve got color-treated strands, chemically straightened locks, or just a plain ol’ heat styling addiction, this might be the one product you didn’t know your hair desperately needed.

First Impressions: Small Bottle, Big Expectations
When my Olaplex No. 7 arrived, I did a double take. This is it? It looked so small I wondered if I accidentally ordered a travel size.

Why It’s Different: It’s Not Just Oil, It’s Science
Here’s what makes this little bottle unlike any other hair oil:
Most oils sit on the surface of your strands, temporarily masking damage and smoothing flyaways. Olaplex No. 7? It actually repairs broken disulfide bonds inside your hair.
It’s powered by Olaplex’s patented bond-building technology, the same science behind their cult-favorite No. 3 Hair Perfector.
In other words, it’s not just making your hair look healthier—it’s helping it actually become healthier.
How to Use It Like a Pro
You don’t need a 10-step haircare routine to make this work. In fact, it’s so easy to use, it fits seamlessly into any routine:
For Wet Hair:
-
Towel-dry your hair
-
Apply 2–3 drops to mid-lengths and ends
-
Comb through and style as usual
For Dry Hair:
-
Use as a finishing oil to tame frizz, add shine, and protect from heat
Pro tip: Mix a few drops into your Olaplex No. 6 Leave-In Cream for an ultra-smoothing cocktail. Thank me later.
My Results After 30 Days
Okay, let me just say this: my hair has NEVER looked this good.
-
Week 1: Immediate shine boost. My hair felt silkier after one blowout.
-
Week 2: Frizz noticeably reduced—even on humid days.
-
Week 3: Ends looked less crispy, and breakage seemed to slow down.
-
Week 4: Hair color looked more vibrant, and people started asking, “Did you do something new to your hair?”
It’s the kind of transformation that makes you want to flip your hair every time you pass a mirror.
