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.

  • I've used Olaplex No 3, No.6, No. 5, and the bonding oil and I've loved all of them! I have wavy hair that is completely different textures from the top of my head to the bottom. I've found that Olaplex (especially the oil) has been one of the only products to tame frizzy curls and revive dry ends. It also smells amazing!

  • Works well on damaged hair, but using too often dries your hair out. The oil is great for dry ends.

  • I am a big fan of the Olaplex number 6 leave-in for my thick, coarse, unruly, frizzy, curly hair. I use it both on wet and dry hair but really love it in dry hair that has gotten frizzed and out of control. It smooths out the frizz and brings the style and definition back in a way nothing else has. It is definitely a go to product for me. I have tried all the Olaplex products and they are all nice but I didn’t notice a positive difference in my hair until I tried number 6. This one product was definitely worth the money.

  • What can I say about olaplex besides I love number 3? I use it about once a week at max and it leaves my hair silky smooth and soft. Before using, it was difficult to run my hands through my hair because I have such hard water in my pipes. This made a world of difference, with just an hour a week!

  • Works well for damaged and/or color-treated hair and has a bonus of making your hair super soft. Definitely not for use every day, but maybe once a week.

  • I have only ever used the leave in bond repair and dont notice much difference. I figure maybe if I used the full line I would notice less dryness and breakage.

  • Pros: objectively makes my hair silky smooth! Cons: It’s really expensive for the amount of product you get, and I can’t help but think the chemicals in the product (mostly because of the smell?) are slowly killing me.

  • Love the n3 once a week, my hair is super shiny. the oil is nice as well during winter

  • I have damaged hair from bleaching for a few years and I’ve tried systems 3, 4, 5 & 8. Didn’t notice a difference in hair health using these together, it could be that my hair was just too damaged. Didn’t work for me but may for you!

  • Amazing quality hair products. Worth the money!!

  • I've been dying my curls for decades, and Olaplex 3 has been instrumental to keeping them shiny and healthy. I use it religiously once a week, and I have had so much less breakage since. If you color, heat style, or otherwise damage your hair you need to add these to your routine.

  • I love the range that olaplex has. I just wish i saw results. I'm not bashing the company i think some of their products are great.

  • I wanted to love this because so many people love this brand, but it really dried out my hair.

  • Smells great and anti brassiness, this is highly pigmented. Gets the job done and worth every penny

  • Olaplex #3 bond repair is an OG! I've used this product on and off for years but it is worth the hype. I am interested in trying other products in their hair care system. The only barrier for me is the price tag. The products are expensive, so I am hesitant. After my experience with Olaplex #3 though I am almost convinced to try more. It is a small bottle but it really does help my hair texture, it smells great, and it lasts a lot longer than you'd think (I have very long hair, as well). Whether it is used for color damage, heat damage, or used on virgin hair, I have always had a good experience with this hair mask.

  • Smells great and definitely helps to detangle my hair however the price is high for the small amount of product

  • I had super damaged hair from bleaching it and the N3 SAVED my hair! Literally brought it back to life.
