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 has literally saved my hair. I struggled to get my hair to grow rather than breaking off once it reached a certain length for years and I started using Olaplex close to 2 years ago now and my hair has never looked or felt better, not to mention the AMAZING growth I have had from it as well!! These products are no joke. But like any other line of products. They work as a system, you want to use them in their system lineup and stay consistent with them to see results. I feel like a lot of people try just one product and think its going to change their life but products that are created in a system, need to be used in that system. Stick to it and you'll see the results!!!

  • I really love how it makes my hair feel- I've used the #0, #3, #4, #5. Since I have thinner hair, I don't use the #3 on my scalp, and I prefer the clarifying shampoo to the regular #3. It makes my hair super soft!

  • who doesn't love olaplaex I love they're heat protectant and of course the shampoo and conditioner is a basic, a bit pricey but if it was a bit cheaper I would say totally worth it! it changed my hair for the better

  • I used Olaplex for several years. However, it got too expensive and I read about the lawsuit of many women experiencing hair loss patches from the product so I discontinued using it.

  • I've used EVERY SINGLE PRODUCT in this line, and absolutely love what it has done to my hair.

    The only con is thet the purple (4p) doesn't have a strong lather. I sometimes feel my hair isn't as clean as I would like it to be. I am obsessed with the 3, and the oil is unreal. It's done amazing things for my hair.

  • I’ve always bleach my hair so it was fairly damaged. The whole system has really brought my hair back to life and it’s so healthy and smooth now!

    Feedback

    I know this doesn’t work on all hair types but if you have fairly straight/wavy hair type it will definitely help.

  • I love these products. The conditioner, the oil and the the hair mask are all so amazing

    Feedback

    Conditioner is so thick that it’s hard to get out of the bottle. I do it though

  • not really a fan of this, im not sure if it wasn't transitioned right on my hair but it made my hair stringy and feel heavy. i have coloured hair so this may have had something to do with that. it was a very average product for me.

  • I’ve tried quite a bit from their product line and most things I’ve absolutely loved. I started using no. 1 & 2 when bleaching my hair and the difference it made was amazing. It really helped keep my hair in good shape while putting it through such a rough process. I also use the no. 4 purple shampoo and the conditioner, as well as no. 8 once a week. I also use no. 9 after washing my hair. I can say that I love all three and would continue to purchase them. The Olaplex products I’ve tried have all helped keep my hair healthy and very soft. The difference it’s made has been quite noticeable.

    Feedback

    The products work wonderfully but I feel the price is a bit high for the amount of product you get.

  • Have been using for over a year and don't really see a difference. probably good for dyed/damaged hair but doesn't do anything special for normal hair. would not buy full price

  • Olaplex nº 5 works wonders on my hair.But I wouldn't say the same thing of all the products.I have blonde highlights and Olaplex nº 4P makes my hair dry, but it's true it does help maintaining blonde

  • i think it works pretty well and leaves my hair feeling strong and silky. a little goes a long way and worth the price

  • I have every Olaplex product and love it all. They are so moisturizing but don't leave your hair greasy. A little goes a long way, as well! I use the shampoo and conditioner once a week and the bonding oil on my ends when I am on my day two hair so it locks in the moisture!

  • I had used the 5 minute leave-in conditioner one time year ago and I lost SO much hair. I actually got so worried that it would continue to fall out. I will never use Olaplex again and advise anyone against using them. I have heard from so so many people that their products are not good and for how much is being charged, there are numerous other places you can take your money.

    Feedback

    The products are full of all kinds of chemicals and I think that is what led to me losing so much hair in that ONE use. I would strongly advise against using Olaplex.

  • Highly overrated from Hairstylists. It is however a good brand and their products are good. There are other alternatives just as good as olaplex.

  • I think this product is overrated and made my hair greasy

    Feedback

    I think the ingredients need to be cleaner and the product should be cheaper
