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.

  • A little goes a long way with Olaplex’s products. I’ve tried their shampoo, conditioner, and hair oil. When I first used the shampoo I was shocked by how little it took to create a full lather for all of my hair - compared to typical drugstore shampoos that I’ve used in the past, I’d say a quarter of the amount does the trick.

  • I used to love all their products but feel like there are better choices on the market

  • I received this as a gift and fell in love, this will be my new go to product

  • I tried to love Olaplex, but I don't. It does nothing to my hair despite trying different techniques and watching different tutorials on socials. I tried it on bleached hair, I tried it on my natural hair - nothing! I tried pretty much every product and the only one that I liked was the oil.

  • The best hair care products made for blondes, sure that you won’t be disappointed!!!

  • I've been using Olaplex as a bond builder on my hair ever since I started bleaching it about 3 years ago. It's stayed in great shape (according to my hair stylist who had recommended it), and I use it as directed! I know there has been some recent controversy with the side effects of the product, but I personally have not faced any of those, and I've been using a variety of the products too (I think I have 0, 3, 4, 5, 6, 8, and 9 all in my closet right now). My favorite is number 8 - that moisture mask is amazing! I do not see a noticeable difference after using most of the other products, however. Especially the toning shampoo - it does not tone as well as other purple shampoos I have tried. But I'm sure it works differently on everyone - my hair is naturally a mid-brown. There are of course so many products in the system and different directions for each, which can be complicated and time consuming. Sometimes I wonder if it would be cheaper to me to just go to the salon every once in a while and get a treatment for hair damage, because Olaplex products certainly are not cheap, rather than do these time consuming hair masks once a week.

  • A Sephora rep recommended this for my fine wavy hair. Not for me but… huge but…. Very high quality and smells amazing! Just not for my hair.

  • This last year I went from having black hair to platinum blonde and this definitely saved my hair. I love all their products I just wish they weren’t so expensive.

  • 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.

  • 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.
