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 products are hit or miss for me, but for the most part I really like them! Some tend to make my hair super greasy, but others do not. I especially love their dry shampoo!

  • I love this brand buy it from Sephora. Helps my hair healthy. I use it once a week to strengthen my hair.

  • I was so excited to try this product after I started dyeing my hair because of all the hype, but unfortunate it didn't live up to it. While the mask definitely made a difference on my bleached and dyed hair, I had better and faster improvement with other products. That difference paired with the cost for the quantity, I found that Olaplex is just not worth it.

  • I started using Olaplex when it was a salon only product, and it definitely helped protect my fine curls as I bleached and dyed my hair for a few years. I used N3 for a bit, and it helped some, but never quite as much as I hoped for. This might have been user error, or the fact that things always feel better in the salon. I wasn't really impressed when I tried a sample of their shampoo and conditioner. It might make more of a difference over time, but the two uses I got out of the sample didn't make a noticeable difference in my hair.

  • I used both the purple shampoo and conditioner. Loved the smell and it worked quite well on my hair. Only downside is price-- I ended up switching to Sachajuan for the same results (if not better) and more affordable price point. Definitely lives up to the hype though.

  • A little goes a long way!

  • Olaplex number 3 CHANGED and saved my hair overnight. I have been a double process for a lot of years and that can lead to a lot of hair damage. So, to address the breakage and dryness my stylist recommended I give Olaplex a try and let me say, this is a GAME-CHANGER, I highly recommend anyone with treated hair keep this baby in their haircare arsenal.

  • It’s nice, it smells good. Personally I’ve seen really similar results with products that cost about half.

  • Olaplex is like the superhero my hair didn't know it needed. 💥✨ I mean, let's be real, my hair's been through some stuff – heat, color, you name it. But Olaplex swooped in with its magical formula and said, 'I gotchu, fam.' 🦸‍♀️💆‍♀️ Now my locks feel stronger, shinier, and ready to conquer the world (or at least a good hair day). 🌟 If you haven't tried it yet, you're missing out on hair-repairing wizardry! 🪄🌪️

  • I used this product every other week and my hair feels so much more thicker and balanced scalp!

  • their hair treatment saved my life when i bleached my hair. their shampoo and conditioner makes my hair so soft! the bonding oil is alright but too much $ for what it is (in my opinion).

  • This is the rare brand/product that I have no hesitation recommending to anyone, even with the price tag. Olaplex makes high quality hair products that have absolutely made a noticeable difference in the look and feel of my hair/scalp. I have 2C/3A type curly hair, and my stylist noted an improvement in my curls since I’ve started using these products.

  • fantastic. my hair has never been stronger, thicker and more smooth! I've been using a few products for amount 3 months now and really notice a difference. I never thought i would but i do an now I'm a believer!

  • I use the shampoo, conditioner and purple shampoo for my very fine hair. The conditioner does not weigh my hair down once dry and I can tell it really moisturizes. The shampoo lathers very well. The purple shampoo is HEAVILY pigmented so beware, but it does work very nicely.

  • As someone with very dry, curly hair, my curls have always responded very well to the olaplex line! The science behind the products is something I can really respect as a consumer. I find this brand to be my splurge when I go to Sephora. The look and feel of the products feels luxury. Overall, I really love this line and would recommend it to someone who is looking to splurge a bit on their hair routine.

  • I loved Olaplex, I used it religiously- #3 #6 purple shampoo. However- as a double processed platinum blonde I soon found out that using this product could be at the detriment of my hair. After three years, my hair rapidly and over night began to break all around my crown and face. My new hair stylist said it was from too much protein in my hair follicles from over use of Olaplex. It softened my follicles causing them to break. I’ve since taken a break from using the product and my hair is now on a journey back to being healthy. My hair dresser said I can get to a point where I’ll be able to use any protein rich product again, but this time I’ll probably use it few and far in between instead of by the direction.

  • Love no. 3 product, it has revived my hair in a way no other product has.

  • I love the No. 3 hair perfector for maintaining my hair between cuts. The No. 6 can be a little heavy for my hair as a leave-in conditioner, but the No. 7 is a great lightweight finishing oil. Olaplex is my go-to when I need a hair pick me up :)
