Reviews mention

  • Transformative bond-repair technology
  • Highly concentrated, efficient formulas
  • Salon-fresh, clean fragrance
  • Standout purple toning performance
  • Occasional drying shampoo texture
  • Heavy residue on fine hair
  • Purple pigment staining risk
  • Inconsistent long-term results

OLAPLEX delivers noticeable repair and shine for many—especially bleached and color‑treated hair—with standouts like No. 3 Hair Perfector, No. 6 Bond Smoother, No. 7 Bonding Oil, and the 4P Purple Shampoo frequently praised in reviews. However, reviews also flag drawbacks: some experience dryness, heaviness or greasiness, residue, overly strong toning or staining from purple products, mixed or short‑lived results, and concerns about overuse or sensitivity, making OLAPLEX effective but not universally foolproof.

  • Generally works as advertised. It’s my “base layer” on taming my grey hair and its shitty texture. (Another leave in mask and then a little heat protectant spray and she abides, mostly)

  • Form the smell to the feel of my hair after using the shampoo and conditioner, i love this brand. Now that i no longer color or bleach my hair, i use it far less frequently. However, i still use the oil because i like the feel of my hair, the glossiness, and lack of buildup that happens after repeated use.

  • A little goes a long way with Olaplex’s products. I’ve tried their shampoo, conditioner, and hair oil. When I first used the shampoo I was shocked by how little it took to create a full lather for all of my hair - compared to typical drugstore shampoos that I’ve used in the past, I’d say a quarter of the amount does the trick.

  • I used Olaplex shampoo for a while- it lathers really well, smells nice and your hair is left with that 'just left the salon' feel. I started to notice over time it totally changed the texture of my hair from wavy to very straight with little volume. Stopped using it for that reason, but my Mom really likes it.

  • I used No.7 and I experience breakage. It also completely changed the texture of my hair. Unfortunately, this product isn't for me.

  • The olaplex hair mask didn’t work well for me. I didn’t see a difference in my hair and was not worth it to me.. especially for the price

  • Didn’t do much for my hair! I don’t have very damaged hair, so maybe I wasn’t the target user. I have thinner hair so it left me a bit greasy.

  • Olaplex's entire line is a hair transformation in a bottle! From No. 1 to No. 8, it's a journey to stronger, healthier hair. It's like a salon experience at home, leaving your locks looking and feeling fabulous.

  • Can never go wrong with Olaplex. My hair is bleached blonde so it’s pretty much my go to for shampoo/conditioner. A bit pricey but at least your hair will look and smell good. Most especially you won’t go bald so I’d say it’s worth it in the end.

  • Tried the hair oil and while it was great the cost was not worth it. Ran out within a month on a $30 bottle, competitors have same quality and cheaper.

  • Olaplex is very hit or miss, I feel that your hair either gets along with the products or it does not. I personally had some hair loss and hair thinning issues with some products.

  • I'm crazy about haircare, and have tried a lot of salon-quality brands over the years. I have tried Olaplex's shampoos & conditioners, styling products, and bond protectors, and Olaplex consistently leaves my hair feeling healthier and more moisturized than other brands. Even during my bleach blonde phase when I used their purples, the shampoo and conditioner make my hair feel less like straw than other heavy hitters like Kevin Murphy and Kerastase. My 2 go-to products that I'll recommend are the No. 3 Hair Perfector (for when I air dry), and the No. 9 Bond Protector (for when I use heat-styling tools). I comb through my hair after towel drying. Both help my hair dry faster and prevents frizz and frying. For hair oils, I prefer Fable & Mane's for the scent, but Olaplex's is still a great option. A small amount of Olaplex also goes a long way, so no need to overload your hair with product. Downside of that is that you pay a lot for a little, which is the primary the reason why I stopped using their shampoo & conditioner. My only other complaint is that the product is a pain to get out of those tiny bottles! You have to keep the bottle upside down or you'll spend forever waiting for the product to come out. Not sure what Olaplex can do here, but better squeeze options for sure!

  • I have a love hate relationship with these products. At first they seemed to help and my hair was easy to style, but then I started using the purple shampoo after going gray and it just dries my hair out so bad. I only shampoo once every three days. The product lasts because you only need a little bit I can’t take the dryness anymore

  • I like the brand and their products but I don’t feel like they made a huge improvement to the condition of my hair. I swim in the ocean every day, so my hair can get pretty dry and tangled. The No 3 hair perfector is probably my favourite product. It does make your hair soft and smooth for a day or so. The shampoo and conditioner was nice to use, but makes my thin hair a bit flat. Same with the No 6 bond smoother. I think it would be great for thick hair though. I do like to smooth a tiny amount of the No 7 bonding oil through my hair to make it shiny. The packing is nice and I enjoy using the products, I’m just not sure they’re the best products for my particular hair.

  • Beware, folks! I recently dabbled in the world of Olaplex hair care, and let me tell you, it was quite the hair-raising experience. Pun intended. First things first, Olaplex products come with a hefty price tag that will make your wallet cry. They should come with a warning label: "Not responsible for financial heartache caused by shampoo-induced bankruptcy." Seriously, I had to take out a second mortgage just to afford a bottle. But the fun didn't stop there. Oh no! After a few uses, I noticed my strands deciding to embark on a mass exodus. Yep, my hair deserted me faster than a contestant on a failed reality TV show. Apparently, Olaplex had a different definition of "hair care," something along the lines of "hair scare." Perhaps their secret ingredient is a potion that makes your hair disappear into thin air. Presto! No more bad hair days when you have no hair left! Genius, right? So, unless you're aiming for the bald eagle look, I'd think twice before splurging on this hair horror show. Save your pennies and invest in a stylish wig instead.

  • Products really work! I had trouble with color damage and breakage, but after a couple of weeks using No. 5 and No.7, my hair is super strong again. These products are on the pricier side, but if you stock up during sales, they will pay off!

  • As a girl with 4A hair, Olaplex does work surprisingly well.
