If you're a hair aficionadoor desperately trying to fix a botched bleach job then the best Olaplex products might need no introduction. The hair-care brand is beloved by celebrities, top stylists, and reviewers alike, and has made a name for itself as a must-have for color-treated hair.
But despite the acclaim, there still seems to be a little confusion around what the products actually do. We'll clear things up: Unlike other hair treatments that add moisture and shine to the outer layers of your hair (pretty straightforward stuff), Olaplex works on the molecular level to repair the bonds that make up our hairand was the first brand to make this technology available in an at-home formula. By restoring these bonds, it makes hair stronger, healthier, and softer, which is how Olaplex came to be recommended by almost every hairstylist out there. This technology is particularly beneficial for anyone with bleached or color-treated hair, but it can also help reverse damage done from brushing, chemical processes, heat styling, and environment aggressors.
Olaplex No. 4 Bond Maintenance Shampoo
Olaplex's No. 4 has been a mainstay in my routine for the last two years. I know most people swear by this shampoo for color-treated hairand while I do the occasional balayage in the summer, it's really the heat styling that does most of the damage. Having No. 4 on deck has totally transformed my hair since I started using it. My split ends look way less split, and my hair has stopped falling out in big chunks when I shower. Everything just looks and feels healthier, which is nothing short of a miracle for my insanely dry and frizzy hair. Talia Abbas, associate commerce editor
Olaplex No. 5 Bond Maintenance Conditioner
Conditioner is a nonnegotiable step in my hair-care routine, so much so that I don't feel like I've washed my hair properly if I don't use conditioner. Which is why I love the No. 5 conditioner. It's part of Olaplex's 3-4-5 system, three products used together that actually deliver results. After shampooing with No. 4, I apply the conditioner from my scalp all the way down to the tips and leave it on for three minutesthe max patience I have for letting product sit in my hair, TBHbefore rinsing. Not only does it make everything visibly softer, but my hair looks less frizzy and dry when I leave it to air-dry. T.A
Olaplex No. 6 Bond Smoother Reparative Styling Creme
This worked very well on my very fine, frizzy hair. A little goes a long way, which I love with a luxury productthis little bottle will last. I smooth a little bit onto damp hair and then blow-dry it, and it gives me much more of a professional blowout look than I can achieve without it. J.S.
Olaplex No. 7 Bonding Oil
I've tried many hair oils in the past, but none has left me instantly impressed as this one. It's simply divine, lightweight with a subtle, sweet scentand my thick, dry, and frizzy hair soaks up it no time. I apply a few drops to the ends and then rake it through, and it gives my hair an immediate shine. The oil also doubles as a heat protectant, so on days when I'm blow-drying, I'll apply a bit before and after styling for a picture-perfect, bouncy blowout. T.A.
Olaplex No. 0 Intensive Bond Building Hair Treatment
Full disclosure, I didn't notice a difference when I used this product solo. But when I used it as a primer for the No. 3 treatmentas recommended by the brand it definitely kicked the results up a notch. My hair felt softer, split ends seem to disappear, and my hair just looked overall more expensive. B.C.
