What the gurus are saying

Lightweight and strengthening, this leave-in is praised for cutting down on breakage and brittleness without weighing down fine strands. The one thing to keep in mind is that a little goes a long way, since too much can leave hair feeling grimy. The one dissenting take prefers K18 for its lighter feel, shine and softness, and it is unclear whether fine hair plays a part.

"Living Proof also has, and I absolutely do love this one, the Triple Bond Complex leave-in that does really strengthen your hair. I sadly ran out of this and I'm waiting for the sale to stock up on this."

"Living Proof's Triple Bond Complex is a product I've finished four times now. I use it after the shower and it minimizes hair breakage."

"And to be honest with you, I think the K18 is way better. And the reason being is because I find the K18 is more lightweight. It's lighter in texture when you apply it to your hair and after you've blow dried your hair and you've styled your hair. The K18, it just makes your hair feel so soft and smooth. It adds a lot of shine and my hair just feels so healthy. With this one, I don't get that. And I don't know if it's because, you know, I have fine hair."
✓Yay
"I love how easy this is to use, in contrast to something like Olaplex number three where you have to let it sit on your hair, or K18 where you have to use it after shampoo but before conditioner. With this you just put it on after your shower. There is one catch, you use less of this than you think, otherwise I find my hair gets kind of grimy feeling. But I do really like this, I think if you have any kind of hair damage it does make a difference."

"I really like Living Proof, they've been one of my favorite hair care brands. I had the chance to try a mini size of their Triple Bond Complex as a gift with purchase, and I feel like it actually is really good. That said, it was just a sample, so I don't want to be sitting here pretending like I have a lot of experience with it."

"A little goes a long way and my hair has never felt softer, I'm really surprised by this product. [...] If you're looking for a hair bonding product to deal with those frizzy ends, my number one recommendation still is the Living Proof Triple Bond Complex, but I have to say I'm reaching for it a lot less often because I'm using the Comeback Kid by Fenty for general scalp health."

"My second wash day is all about bond repair. I tend to have very dry, brittle ends. Especially living in Colorado, it's even drier and more brittle. And so I do a bonder repair treatment once a week. Some people do them once a month. So it really just depends on the quality of your hair. I find once a week works perfectly for me. Some of the products that I love are the Living Proof Bonder"

"I also love their Triple Bond Complex. I like it more than the K18 and the Olaplex Bond repair products. It's very lightweight and it doesn't weigh my fine thin hair down."

"I've been loving this treatment by Living Proof, it's a Triple Bond Complex, very similar to the K18. The K18 irritates my scalp, this one does not, so I've been reaching for this about once a week to once every other week just for a little bond repair and smoothing, just to cut down on the frizz. So if you're having trouble with the K with irritation or not really doing what you want, give the Living Proof Triple Bond Complex a try."

"The Living Proof Triple Bond Complex is a leave-in treatment and hair mask that claims to make hair eight times stronger and more resistant to future damage while adding softness, smoothness, and shine. I use it after every shampoo and I love it. [...] I take about a pump and a half onto my hands, separate it into sections, and scrunch from the bottom up."

"This is the one I use when I get out of the shower. They say this is a weekly leave-in treatment and hair mask that makes your hair eight times stronger and more resistant to future damage while also adding softness, smoothness and shine. I use this every single time I shampoo now, which is generally two to three times a week. I get out of the shower and I put my hair up into a microfiber towel and then about 7 to 10 minutes later I apply the Triple Bond Complex."

"I started using this quite recently and so far so good. It's another bond repair treatment and I use this about every third wash. I apply it to wet hair after the shower. Have I noticed a significant difference? Not sure, maybe, maybe. I can tell you that my hair is infinitely better right now than it was a year ago and I do think it's a combination of these products that I'm using together, but I'm in a happy hair place."
