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.

  • Olaplex is fine. Nothing to write home about. Made my already dry hair feel even more dry. I do enjoy the hair oil but probably will not repurchase.

  • I used Olaplex after going blonde and it was part of the routine that my hair dresser provided. My hair still felt weak and stringy but I think that’s the nature of going blonde. I do not feel like the product made a difference

  • my hairdresser gave me the salon quality protein treatment and it saved my blonde hair. i use it once every month and it's amazing :)

  • I used a full bottle of No.3 and found no difference in my hair. If anything it made it a little smoother in the short-term but I get the same results from a basic hair mask. I use the bonding oil before using heat on my hair and it seems to work well as a heat protectant. Again though, it doesn't make my hair overly noticeably smoother or anything. Note: I have fine hair dyed blonde.

  • I found olaplex quite effective and groundbreaking before I tried other, more effective haircare. It's not bad, it's just not the best on the market, and you can easily overdo it with the treatments. Proceed with caution.

  • This hair mask is the best thing I have ever put on my hair. I also love the smell, it smells like I just spent hundreds of dollars on a hair treatment at a salon.

  • Love a good Olaplex hair mask - don't get me wrong, they really do work! However, I have really curly thick hair and a little does not go along way... I find myself using too much of the product in one use to cover my whole head, which isn't the best for how pricey some of their products can be.

  • I honestly feel like this whole brand is a scam. Multiple cosmetic chemists have said that most of their products don’t really do anything & only the silicones coating your hair are why anyone notices a difference. K18 is much better quality.

  • Except for the price, everything about the products are great. My friend who had dyed her hair had a great experience with it. I have a dry hair and the shampoo, conditioner work so well~

  • Noticed a big improvement in the beginning, now not so much. I love their purple shampoo, I would say it is my favorite product.

  • I used one of their products for my hair, my hair was really soft and felt a bit more healthier.

  • Have used all of their products both at home and at salons. My best advice is to use them at salons as they know how to maximize the benefits of the products. Their products are only effective when use correctly.

  • I had not tried olaplex for the longest time due to their high prices, but the recent deals they’ve had on Ulta and QVC and other platforms have gotten me to try it and I really like their products, especially the 4C shampoo for a weekly thorough cleanse combined with the conditioner!

  • I tried the hair mask and after using it for about 3 months, I didn't notice a huge long term difference. My hair is very heat/color damaged so it is very dry. I noticed improvement directly after using the product but not much in the long run.

  • I invested in the blonde toning shampoo after hearing that it was the way to go. It's been just ok! I don't think it's toned enough and I actually ended up switching to a different non-Olaplex bottle with way better reviews. Ultimately, I think I won't buy Olaplex again, but I think it's one of those things where if it works for you, it works well, and if it doesn't.... it doesn't! Hair and skin are so personal.

  • THE BEST shampoo to resist New York water and help your hair to survive!!! the experience is perfect even tho I find the price a bit too expensive for the quantity we are getting. The journey on the website is a bit complex (a lot of information) but that was OK

  • I can't speak for the other products but Olaplex #3 has been a fixture in my haircare routine for years. It keeps my hair long and strong.

    Nothing, keep the formula the same!

  • My hair is the type that will shrivel up into a nest after bleach contact. Unfortunately, I didn't know that... until after bleach contact. Olaplex saved my poor hair. I watched it go from unkempt to soft and sleek after just one use. I use no.3, no.4, and no.5, but I think no.3 is the real champ if you don't want to invest in the full Olaplex repertoire.
