OLAPLEX reviews and discussion

77% of reviewers would recommend to a friend

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 have been using the OLAPLEX line for the past two years. No.3 is by far my favorite product! It is such a game changer!

  • I think Olaplex lives up to the hype. At first I thought the product was expensive but a little goes a long way and it does last a long time. I love the transformation of my hair since using Olaplex and would recommend it to anyone struggling with damaged hair!

  • I really wanted to like this brand because of the tik tok hype for dry hair. However, each product only hydrated my hair minimally compared to my current shampoo, conditioner, and hair treatment. I actually found the scent a little invasive and the actual products leaving my scalp irrated.

  • Holy grail item for me. I have all of the Olaplex steps and I swear that these products have changed the texture and health of my hair. My hair has never been longer or stronger or healthier and I love the fragrance of these products. Will be purchasing forever and ever.

  • Dried out my hair and my scalp. Actually do still love their oil though. Heard better things from my friends who dye their hair.

  • My hair feels so good after using their products. I had bleached my hair a couple of months ago and this was a life saver! It kept my blonde highlights intact and made my hair look luscious.

  • I have tried a variety of olaplex products including the shampoo and conditioner and the viral number 3 hair protector. I noticed my hair feel softer but no significant changes.

  • This is a product I have a LIKE/HATE relationship with. When I very first ever used it, I loved it. Now I just feel like it is so “fine” or works when it wants to.

  • Terrible ingredients that have negative impacts on women's endocrine system. Much more affordable and clean products out there.

  • The best leave in treatment you can ask for! Lightweight but so nourishing. Extremely good quality product - will never use anything other leave in cream again.

  • The shampoo and conditioner made the texture of my hair different. Did not clean my hair and made it greasy.

  • I love this stuff and even my 10 year old daughter takes this out of my shower! The oil is my favorite but a little bit goes a long way!

  • I dye my hair semi regularly and used it for a few months. Didn’t really notice any difference and kind of expensive for fee results

  • I like it, but its super expensive and sometimes leaves my hair feeling greasy. Not sure if that’s just my hair, though.

  • the shampoo lathers really well, and smells amazing. The conditioner is too heavy for my hair, it pulls down my waves, but I will occasionally use it right after swimming in the ocean salt water so it doesn't damage my ends.

  • I've been using Olaplex for several years now. The first time I used their conditioner, I noticed a huge difference in my hair texture - I also had a lot less hair breakage. I have blonde highlights and Olaplex's blonde/bond maintenance range has been one of very few hair treatment ranges that has made a difference to my chemically processed hair. One thing I have to note, is that it is very expensive and I do wish the products came in bigger quantities, but for the most part, the products are worth it. (Their No 6 didn't do much for me, but the rest was great).
