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 dyed my hair for the first time and it started to get so dry and the color was fading away quickly and transforming into something that was not even close to the original color. I tried OLAPLEX and the color and liveliness of my hair came back. Now I have to re-dye my hair every 6 months (I have a balayage for reference).

  • I used Olaplex shampoo and conditioner for about six months. It didn’t really stand out as anything special and it was very expensive.

  • Olaplex's Bonding Oil is the only product I buy from the brand. I decided to buy this oil because it had so many positive reviews, and I must say, it truly delivers! I have wavy, thick hair, and it effectively controls frizz. I no longer have any split ends! I adore its aroma; it reminds me of oranges. If you enjoy citrus scents, you'll love this oil. The bottle appears rather small, but it actually lasts for months! I share this oil with my mother and sister, and it lasts a few months, even though we have very thick and long hair. A little goes a long way.

  • The No. 4 shampoo and conditioner didn't work well for my very thick / long hair. I needed like 1 tablespoon of shampoo and like 1/4 cup of conditioner for each wash. I found that I needed to wash my hair more frequently and it made my scalp itchy throughout the day. Over time (6-8 weeks or so), my hair also became more brittle and drier. Unfortunately, this product didn't agree with me.

  • did wonders for my hair 😍 i have curly thick hair i could never manage but the bond repair conditioner worked amazingly for me but the price is a lot for the product if you have the money splurge but if on a tight budget then consider only using once a week x

  • The No 3. Hair Perfector is AMAZING! I'll shout it from the rooftops. I use it about twice a month and leave it in my hair for as long as I can while I shave my legs. Your hair has never felt smooth and more silky. I never want to heat-treat my hair again!

  • I have been an avid and loyal Olaplex user for YEARS now and will always continue to do so! I use every single one of their products from N°0 to N°9 and everything in between. I love this company so much and everything their products have done for my hair that the day they went public, I invested. I was a swimmer for 8 years and the chlorine damage my hair suffered, I thought, was irreversible. But by using olaplex products everyday my hair has become strong, healthy, and gorgeous!

  • I am writing this honest review because I feel everyone needs to be made aware of the dangers of using anything from the Olaplex line. I have been a frequent user since it first launched at my hair salon maybe 3-4ish years ago? My stylist thought it would be best to use on my hair due to the light blonde highlights I would get every few months and at first I liked the results of the first treatment so I bought the kit for myself to use at home as “maintenance” in between salon vists and within that first month I began to see breakage like never before happen to my beautiful once long thick hair. The thinning and hair loss started and when I mentioned it to my hairdresser at my next appointment she was aware of the potential problems but continued to blow it off saying the company itself said it’s not true! That for me was a red flag and I have since then switched hairdressers. I now work for Sephora and we have clients firsthand come to us telling of their own personal horror stories of bald patches, extreme thinning and hair loss. There are so many other healthier hair treatment options out there so please do yourself a favor and stay far away from this stuff it will ruin your hair follicles the more you use it.

  • Love Olaplex products, they aren’t cheap but they do an amazing job. The purple shampoo ensures your colour stays in and your hair doesn’t look brassy.

  • I love this brand. I have been getting my highlights since highschool and since incorptating olaplex into my routine my hair feels so healthy and doesn't feel dry and dead from the bleach.

  • Products and packaging look good but their formulas were not good at all for my hair. felt very dry and aggressive. Not a joy to use in terms of smell and texture but most importantly results were bad. I don't understand why this brand is everywhere.

  • THE BEST FOR OVERPROCESSED HAIR.

  • Olaplex products are amazing for healing damaged or weak hair.

  • Over priced and wasnt good for my hair, did more damage then good

  • Amazing product for my dry hair. Only bug bear is the packaging!

  • Best hair treatment I’ve used so far! My hair was damaged and now it’s shining and way healthier!

  • I love Olaplex. I have had super damaged hair from coloring and bleaching and every product in this line has helped my hair. Every time I use it it makes my hair softer and feel stronger.

  • Amazing for extensions

    Friends with OLAPLEX
  • My hair was very very very damage so I decided to use opaplex and since then my hair is healthy and shiny. This brand literally change my life and save my hair.

  • Really recovers damaged hair. My hair is dry due to almost daily ironing and because I highlight it every four months. A friend recommended it and bought it so see for myself. After rinsing it the hair feels smooth and easy to style…
