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.

  • Great product, my hair is so much better

  • The only shampoo and conditioner I use, I always switch and then come right back as someone who bleaches their curly hair it keeps my hair healthy. I also love the oil for breaking the cast when I wear my hair curly as well as a finisher when I give my hair a blowout, I mostly like how light weight it is. I also like No3 but I can't say I see a monumental difference when I use that one.

  • I wish it wasn't so spendy because I would love to be able to use it more often. Makes my hair feel crazy soft and smells amazing.

  • Great for hydrating dry dry hair. But results in oily heavy hair if I use it anytime other than in the winter when humidity is really low. Sugges sample sizes rather than the full size for deep.treatment when needed as expensive, and I worry product will spoil before I use it up with full size bottles.

  • Not for me. Tried their products for months and they consistently left my hair feeling sticky and thick in a bad way once dried. This feeling went away once I quit using it.

  • Use this regularly and it’s a wonderful product for repairing hair and maintaining it.

  • Love the outcome after using Olaplex 1-5. A bit pricey but worth the money. I do not use the purple 4P shampoo as I bought a different one, but I use the products 1, 2, 3, and 5.

    I buy them
  • My hair is so smooth after using this product.

  • Have tried several products and loved every single one of them. My favorite is the hair oil. Makes my hair so shiny and healthy.

  • Olaplex is an original and cult classic for a reason. It’s excellent for bond maintenance, whether you just use whole system or just the shampoo and conditioner. I also love that you only have to use a small amount of product to get amazing results.

  • Its lightweight formula, enriched with nourishing oils and Olaplex technology, absorbs quickly without leaving a greasy feel. After regular use, my hair feels stronger, healthier, and has a beautiful shine. I highly recommend it to anyone seeking a transformative hair care solution.

  • The purple shampoo is effective and removing brassy from blonde hair but it’s very drying. The conditioner is good not amazing. My hairstylist doesn’t use the brand anymore, he said there’s much better options now.

  • i've used many products from olaplex. number three doesn't do anything for me. number zero made my hair break off and doesn't dispense evenly. i would avoid this product at all costs. number 9 didn't make much of a difference, but i have fine hair and i felt it weighed my hair down too much to add into my routine. the shampoo and conditioner smell heavenly!! i have a greasy scalp so i wouldn't use the shampoo regularly, but after a swim i think this would be nice!! i'm obsessed with the conditioner. sooo thick and hydrates my hair really well. makes my hair feel thicker, shinier, and softer. the hair oil is extremely light weight, so don't use it if your hair is thick or very very dry.

  • After trying most of Oleplex products I am more than satisfied with the products… The different deep conditioners are top notch and really make a difference with my hair!!…The hair oil soaks right in and does the job for my hair.. a very little goes a long way

  • I'm a full time hairstylist and I personally think that Olaplex can get mis-used very quickly. I use to use this everyday behind the chair, and now I don't. When it's overused it will cause damage to the hair because it has a ton of protein, so be aware of when you use it how much you are using it.
