I finally started to nail down my hair-care routine in the past few years. Before that, I pretty much just washed it and let it do its thing; I didn't fully understand how or when to layer in different styling products. Now, though, I cringe at the thought of going without a leave-in conditioner [1] and air-dry cream [2] post shower, and I've perfected my method of making my blowout last (when I do it, that is). Something else I'm very into? Reparative treatments that improve not only the look of my hair, but also the actual structure of it. That's where I was first introduced to the Living Proof Triple Bond Complex Leave-In Hair Treatment [3] ($32, originally $45).

There are a few peptide or bond-repairing leave-in treatments on the market right now, and I'm a big fan of most of them. When I got news that Living Proof was launching its own, I couldn't wait to test it out. As a long-time fan of the brand (I have a reserve of the Living Proof No Frizz Instant De-Frizzer [4] ($33) in my house for emergencies), I knew it'd impress me with the formula — and I was right.

The best part: you can score this top-rated leave-in for 30 percent off for Amazon Prime Day, which starts today and ends Oct. 11. Keep reading ahead for my full review, plus before-and-after photos.

What I Like About the Living Proof Triple Bond Complex Leave-In Hair Treatment

When you first see a bottle of the Triple Bond Complex Leave-In Hair Treatment, you may think to yourself that it's pretty small, but that's because a little bit of this cream goes a long way. The technology behind it is pretty cool: it helps rebuild the structure of your hair with its patent-pending technology by creating a 3-D network for the hair follicle. It also contains encapsulated cellular oil to protect against UV and heat damage and a blend of biomimetic emollients to smooth the fibers in your hair, boosting softness and shine.

This may sound super complicated, but to summarize: it leaves your hair stronger after one use, mends split ends, protects against future damage, and restores shine. It sounds too good to be true, I know, but after using it for the first time, I can confirm it delivers.

How to Use the Living Proof Triple Bond Complex Leave-In Hair Treatment

To use the Living Proof Triple Bond Complex Leave-In Hair Treatment in your hair routine, you simply wash and condition your hair as you normally would in the shower. Then, on damp hair, you comb two pumps throughout your head (you can use more if needed, but two goes a long way) and let it sit 10 minutes. Once that time is up, you simply give it a blast of heat with your blow drier to seal it.

This last step is key, because the technology is heat activated. Fans of air drying (like myself), don't worry: it only needs a minute of heat to work, so you can give your head a quick once-over with a hair dryer and then continue letting your hair dry as you usually would.

What to Consider Before Trying the Living Proof Triple Bond Complex Leave-In Hair Treatment

Immediately after applying the Living Proof Triple Bond Complex Leave-In Hair Treatment, it was hard to tell a difference in my hair, but once it was completely dry, it was impossible to miss. My hair felt softer than it ever had before, and my ends, which were a little dry before, were more hydrated. It also looked shinier and smoother because the leave-in treatment sealed the cuticle of my hair and reduced the frizz I usually see on my waves. This was after letting my hair air dry overnight, too.

The results of the Living Proof Triple Bond Complex Leave-In Hair Treatment lasted for days after I used it, which is great considering it's designed for weekly application. It can be hard to see a noticeable difference in your hair after using a product only once, but this leave-in treatment blew me away.
