OLAPLEX earns polarized reviews: it visibly strengthens and revives bleached or damaged hair—No. 3 Hair Perfector, No. 6 Bond Smoother, No. 7 Bonding Oil, and the 4P Purple Shampoo are frequent standouts—yet many users report dryness, heaviness, or even increased shedding and brittleness if overused. The brand is praised for salon-clean scent, rich lather, and fast toning, but criticized for inconsistent results across hair types and small, hard-to-dispense bottles.
AI summary based on Thingtesting reviews
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.
Works like wonders for 6 months then destroys your hair.
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~

Only has a limited effect on my hair. Very expensive.
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.
High-performing products! Definitely felt like I elevated my hair care routine.

Hard to dispense products/squeeze remainder towards the end.

I used this bonding oil one time and it made my fine hair feel very brittle and it caused more hair fall out than with my normal shampoo. I returned the product to Nordstrom . I would not recommend. But maybe it just wasn’t for me.
i like their clarifying shampoo and whatever my hairdresser uses when i get an olaplex treatment. overall though their shampoo and conditioner are not necessarily worth the price.
The hair oil is quite nice, but I haven’t been a fan of any of the other offerings in the line. The shampoo and conditioner were particularly disappointing.
I’ve been thoroughly impressed with Olaplex No. 4C Shampoo and Conditioner. These products have transformed my hair care routine, leaving my hair feeling incredibly clean, hydrated, and manageable. The shampoo effectively removes buildup without stripping natural oils, while the conditioner provides deep nourishment, making my hair silky smooth and easy to style. What stands out the most is the noticeable reduction in breakage and overall improvement in hair health. Olaplex No. 4C is a game-changer for anyone seeking strong, vibrant hair.
