OLAPLEX reviews and discussion

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.

  • High-performing products! Definitely felt like I elevated my hair care routine.

    Feedback

    Hard to dispense products/squeeze remainder towards the end.

  • I used this bonding oil one time and it made my fine hair feel very brittle and it caused more hair fall out than with my normal shampoo. I returned the product to Nordstrom . I would not recommend. But maybe it just wasn’t for me.

  • i like their clarifying shampoo and whatever my hairdresser uses when i get an olaplex treatment. overall though their shampoo and conditioner are not necessarily worth the price.

  • This is a great brand. My daughter & I do a lot of color swapping- now she’s more highlighted & has snagged the bottle for her blonde. She’s using the purple. It works great & doesn’t make her hair look greasy like another product that we both tried. It’s worth the value but was hoping for a larger bottle last Amazon purchase.

  • I’ve been thoroughly impressed with Olaplex No. 4C Shampoo and Conditioner. These products have transformed my hair care routine, leaving my hair feeling incredibly clean, hydrated, and manageable. The shampoo effectively removes buildup without stripping natural oils, while the conditioner provides deep nourishment, making my hair silky smooth and easy to style. What stands out the most is the noticeable reduction in breakage and overall improvement in hair health. Olaplex No. 4C is a game-changer for anyone seeking strong, vibrant hair.

  • I've tried the N3, and I loved it at first, until I realized it started drying out my hair. Ended up throwing it away. Would not retry it at all. Also used the hair oil, and it made my hair greasy and heavy even when using just a smidge and only for the ends.

  • I've used Olaplex at various points in my life but never loved the products enough to repurchase immediately when I run out.

  • I love this stuff. I wish it were a bit cheaper, but I do find that every time I use it my hair feels really nice. I especially like the conditioner.

  • On the high end side but I think it works for me, help my hair stronger

    Purchased
  • I use Olaplex hair and N3 regularly. My hair is so shiny and smooth, there's been a noticeable difference since I started using Olaplex products

  • New to this product after reading reviews. Initially I thought it was too expensive, however after taking the plunge, this shampoo is excellent, particularly for drying hair and hair that is turning grey. My hair looks and feels the best it has in years

  • My hair is definitely smoother and appears healthier. Takes out the brassiness. It does not weigh my hair down either (my hair is fine and straight)

  • Olaplex has become a love-hate product but let's be clear -- this is NOT meant to be used every day. Olaplex 3, which I would recommend wholeheartedly, is something I use once a month because I have thin hair.

  • Not every product for every day, but best for those after DIY home hair dye sessions.

  • Not my favorite. Although I risk results seem promising over months my hair dries out with regular use. The condition treatment causes me to have breakouts.

  • I splurge on the reconstructor 1-2 times a year when my hair is super fried, and it helps every time. I have tried the more preventative products (shampoo, conditioner, leave-in) and they were nice, but did not provide the level of results to make it seem worth the price. I will continue with the treatments as needed.

    REALLY expensive

  • Olaplex No. 3 is lifechanging. I honestly didn't even really understand what the product was intended to do until I tried it. Your hair will be a fully different texture, so soft and luscious.

    Feedback

    The hardest part is waiting the 10 minutes for the product to work!

  • Great - love the mask

    Feedback

    Price point could be lower, also more ingredient transparency plz

  • Olaplex is UNREAL! I color my hair regularly and have for years, which takes its toll for sure. I started using Olaplex about 4 months ago and have been blown away by the way my hair has improved since then. I use the full bonding system and it leaves my hair silky-smooth and frizz-free, not to mention more manageable overall. I've even seen an improvement in growth. LOVE it.

  • These have made a world of difference making my hair nice and soft again
