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 tried the No 3+4+5+6+7 from Olaplex. The Shampoo and Conditioner did not impress me. The Bonding Oil and No 3 Perfector seemed to make an impact of smoothing out my blonde hair. I would still use again but I'd say it does not justify the price.

  • While olaplex is definitely expensive their products do work amazing in my hair and keep it moisturized and help repair from heat damage.

  • Good quality products and solid instructions going from one number to the next. Heard it wasn't great for every day use (not that I wash my hair every day), so usually pulse in the product here or there rather than always use.

  • The olaplex oil is my everything- the smell, the shine, it is beyond!!

  • Love the bond enhancer, but can be cost prohibitive. It has obvious results, especially on my damaged hair. It’s a lifesaver for someone who relies on heat tools.

  • LOVE THIS BRAND!! Number 3 worked WONDERS for my damage hair! Be careful… too much can damage your hair further

  • Olaplex n3 is an amazing products that works wonder on my split ends, I do a old old 'dose myselfy in it' treatment every now and then and It keeps the hair nice and silky. Many of my friedns use this too!

  • I used some samples of Olaplex for my hair and they were very useful

  • I have the conditioner. My mum has the whole line and likes it a lot. She has thin type 2 hair. I have type 4B/C. It is very thick so I leave the bottle upside down and a little goes along way. I would be curious to try the whole line- seems to be on the pricier point s. But from what I see it is worth it

  • Lightweight conditioner that made my hair feel silky and strong. Love massaging this in and then leaving it for an hour while I read in the bathtub. Feels like doing something nice for my hair when I use this.

  • I began using the shampoo and conditioner when I found them in my sister's bathroom. I didn't know the brand at first, but after trying it, I was impressed. It consistently left my hair feeling soft and looking shiny. Plus, it feels very natural and doesn't give that unpleasant, heavy product sensation on my hair. That's why I started buying it for myself.

  • I love the number 3 mask and no 7 bonding oil, I notice a really clear difference in the shine and overall healthy appearance of my hair after using them. The oil really smooths frizz and makes a massive different to natural air-dried hair. I've tried the whole range and I don't really feel the other products are worth the huge price tag to be honest. I'm also unsure as to whether I'm going to keep using these products as my hairdresser told me Olaplex are being sued for causing hair loss and that some products are flamable!!

  • I find Olaplex better for dry hair. I have thicker hair and any time I use it I feel like it weighs my hair down. I don't have volume and it gets so much oily faster. Though I do know people that this product does work for.
