  • Noticeable bond-repair performance
  • Shine-boosting lightweight oil

OLAPLEX earns polarized reviews: many report visibly stronger, smoother, shinier hair—especially with No.3 Hair Perfector, No.6 Bond Smoother, No.7 Bonding Oil, and the 4P Purple Shampoo—while others experience dryness, heaviness, greasiness, or no lasting improvement. Reviews suggest it can work brilliantly for bleached/blonde or damaged hair but may weigh down fine hair and effects may fade without consistent use; some users also mention fragrance concerns and allegations of hair loss or irritation.

  • 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.

  • I’ve tried almost all the Olaplex products and have loved them. When you use the entire system, you will truly see all the benefits. But you can still get lots of improvement just by using your favorite. Mine is the hair oil, I just wish it came in a bigger bottle. I realize you only need a little bit, but I have a lot of hair and go through the bottle so fast.

  • This is therapy in a bottle. It really seems to be nutritious for your hair making it healthier and luxurious looking .

  • No.6 is amazing! Makes my hair incredibly soft, and smells great!

  • I use the No. 4 bond maintenance shampoo and conditioner, purple shampoo and the hair oil every week. I love the way my hair has transitioned and strengthened my hair! Definitely recommend
