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 used and loved Olaplex from the beginning on but I think other brands and products have replaced it as THE holy grail in the meantime. I loved No 1 and 2 (the salon ones) and No 8 is a great mask. But I have the feeling that all other Nr are just diluted versions of these and are therefore rather unnecessary. The shampoos are too harsh for my colored hair.

  • I tried their number 5 shampoo and wasn't super impressed for the price. It felt better than most drug store shampoos I've used but I didn't see a huge difference in my hair health and it didn't help my scalp health much.

  • I tried their shampoo and bond maintenance conditioner recently; they both made my hair softer, but I don't think the results were as dramatic as claimed. It's also pretty pricey and I go through it very quickly as someone who washes my hair at least every other day. I would very happily use it again if it were given to me as a gift, but I'm currently using cheaper alternatives that I feel work just as well.

  • I like this brand. Their scents are really nice and I’m obsessed with the scent of no. 7. I’ve tried no. 4-7. Did it make noticeable improvements to my hair? No, I don’t think so. Is it still decent shampoo/conditioner? Sure.

  • As soon as I read the amazing reviews for Olaplex, I was desperate to get my hands on some to try to get my dry, bleached hair back to its former glory. I bought the Olaplex No 0 Bond Builder and the No 3 Hair Perfector, as well as the 4P Blonde Enhancer Toning Shampoo and No5 Bond Maintenance Conditioner. I loved the shampoo and conditioner: the shampoo leaves my hair a lovely purply grey tone and the conditioner really softens my strands. The shampoo doesn't dry hair like a lot of other toning shampoos do. However, the Olaplex No 0 Bond Builder was messy to use and doesn't last long for the price. The No 3 Hair Perfector does seem to strengthen my bleached hair and makes the follicles smooth and flat, and I'm on my third bottle having bought a three pack. At the same time though, when I use any of the Olaplex products I do seem to lose more hair than with other brands and products. Because of that, I don't think I will rebuy once these products are finished.

  • Mixed feelings on this brand and products! My salon uses this and it is such a luxurious experience. However, the fragrance is extremely strong and gives me a headache. My hair feels really good after the salon but the price point doesn’t feel right to adopt at home for every day use.

  • I love the No. 3 repair mask, and the No. 6 Leave-in cream, but not a fan of the shampoo & conditioner.

    Feedback

    I love the No. 3 repair mask, and the No. 6 Leave-in cream. Both of these when used correctly helped my hair get healthy & strong. I would recommend both of these, but as they are bond repair products, be sure to check how to use them for your hair type. I don’t believe I had negative impacts from the shampoo & conditioner as I have heard from others, but also did not see any positive results.

  • At the recommendation of a hair stylist I tried No. 3 to strengthen hair. Didn't notice a difference.

  • I love the smell and consistency. It made my hair feel very healthy - but had to wash my hair everyday - because it got very greasy - maybe the wrong formulation

  • Tried Olaplex No.3 when my hair was coloured. It helped keep my hair feeling soft and from breaking after multiple bleaching/dye jobs. The only thing is if you stop using it the effects are gone pretty fast.

  • Olaplex has always done wonders for my hair. I’ve tried many different products now and they’re all so good. It keeps my hair staying healthier and the purple shampoo/conditioner have kept my hair such a pretty blonde!

  • I’ve been using OLAPLEX since Christmas because it was gifted to me by one of my girlfriends. I’m not sure how I feel about the product. I’ve read a lot of reviews stating it’s the cause of their hair loss and I cannot confirm or deny the statement. I lose hair regularly but I’m unsure if it has anything to do with this product or if it’s caused more than usual.

  • Olaplex is a standout brand that lives up to the hype, offering a scientifically backed solution for repairing and strengthening damaged hair. Whether you have color-treated hair, heat-damaged strands, or just want to improve the overall health and texture of your hair, Olaplex provides effective and noticeable results. While it may not be the most affordable option on the market, its premium performance and ability to truly restore hair make it a favorite for many.

  • Hyped up for a reason, I think that Olaplex works, It helps the hair's bond strengthen and can do a lot of good. However I don't think every product is created equally. I think that Olaplex has some strong options like No5 conditioner, but it's not my choice for long term usage.

  • This is a high-end luxury hair care looking feels great and it goes and applies. Well I appreciate it that combination for shampoo conditioner, and bonding oil. I think it makes for a really strong hair routine but of course for the price. I don’t use that every time.

  • I used to swear by the number 3 but it seems like they changed the recipe recently and it doesn't work nearly as well. It's not really worth it for the price anymore so I probably won't be buying again anytime soon.

  • People say Olaplex is revolutionary but I saw little improvements when I tried it on my hair. I tried their hair mask and it was a nice conditioner but it did nothing different from my usual conditioner I get at Costco

  • I have been using this shampoo and conditioner set and it has been great on my hair so far it lasts forever and it seems high-quality and my hair always seems super soft after using it. I haven’t had any issues with dryness like some other brands can give me.

  • Lovely scented product, and love how it makes my hair feel. It is pricy and the shampoo and conditioner bottles are very small in size. I would like to consider some of their styling products next time I make a purchase, I only tried the travel shampoo and conditioner.

  • Olaplex is definitely a well-known brand in the hair care world, and I can see why. The Bond Builder treatment (No. 3) has definitely helped with my hair’s overall strength and shine, and it’s been great for reducing some of the damage from coloring. I’ve noticed my hair feels smoother after each use, and it does a solid job of improving texture. That said, I wasn’t as blown away as I expected. While it does help, it’s not a miracle worker, especially when it comes to severe damage. The price point is also pretty steep for the size of the bottles, so it feels like more of a splurge than an everyday product. Plus, I wasn’t crazy about the scent — it’s a little too neutral for me. Overall, Olaplex is a good product and works well for maintenance, but I’m not sure it’s the holy grail for everyone. It’s worth trying if your hair is moderately damaged, but don’t expect instant, dramatic results.
