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.

The healthiest my hair has ever looked and felt. Believe the hype.
I use the No 3, it seems to work decently as a bond repair with sporadic use on my dry, dyed, and curly hair. It is a very high price point, but that particular product can last awhile depending on length and thickness of your hair.
I really wanted this to work for my hair but it didn’t.

Clean, simple, effective. What's not to love? Products works great on my regular dark hair, and perfect options for when I go platinum too.

Conditioner is tricky to squeeze out at times, but not impossible. Could be improved, but not the end of the world. I still use it.
Love this brand and all of their products! They make my hair feel so much healthier, softer and overall just better. My only wish is that it was a bit nicer on my wallet.
I’ve been using Olaplex for years as I’ve been bleaching my hair for a very long time, and it was always the go-to recommendation by my hairstylist(s). It’s impossibly to deny that #3 is amazing…both in how it works and the way it smells, it’s all simply too overpriced for too little product. In addition, they don’t have the best formulas and there were some sketchy ingredients listed last time I checked (maybe a year ago). Because of that, I stopped purchasing it.

Be upfront about the chemicals and formulas of your product. While I’ve never experienced any side effects, I’ve read that some are harmful for women who are pregnant or trying to conceive. If the formulas have been changed, I’d be willing to give them a try again…maybe. It’s hard to earn back a customer’s trust as a brand once you’ve lost it. Also, far too pricey!
The Nº.3 HAIR PERFECTOR has noticeably improved my hair drastically in just a few uses. I was very pleasantly surprised and can't wait to try their other products!

Both my hairstylist and I noticed a dryness in my hair after about a month of using their products. If you are going to purchase, make sure to not use the shampoo and conditioner every time you wash your hair. I’ve sense stopped using Olaplex.
I use two different Olaplex products. Both are equally great for helping to restore my hair into better shape. My hair gets dried out and this helps reduce the dryness and fizziness.

It's expensive but worth the money.
The No3 is my go to hair mask - it makes my straight hair super smooth and silky. Perfect for winter time.

I’ve used almost all of their hair products. I’m really into clean beauty so their hair products are a staple for me.
I've only tried their new heat protectant but it's worked really well for me! My hair is actually much softer, silkier, shinier, and more manageable when I use it before drying my hair.
Expensive but effective. I’ve tried a gift set and it worked well for my hair. It’s proven to repair hair and the results showed for me. I haven’t repurchased because it’s expensive and I have a lot of hair, but if you have the budget for it then give it a try!

K18 Hair Mask did the most for me, if you’re deciding between the two (Not sponsored at all, I’ve just tried both out and had better results from K18).
This stuff really does help repair hair. I've been using it for years and I've been able to grow it much longer than I used to be able to thanks to this.
Feedback
I do wish they had unscented or less scented options, some of the fragrances are way too heavy
I use their no 6 product after every shower. has improved overall hair health
I've been using the Olaplex line for two years now. The Bonding Oil and No.6 are my holy grails!
Feedback
The shampoo and conditioner are expensive and the quality is meh. There are definitely better repairing shampoos/conditioners out there.

I used this when my hair was bleached and it kept it healthy. Didn’t feel worth paying for after my hair grew out but I’d definitely use again if I had bleached or dyed hair.
I have loved almost every single product from this brand! I use the oil almost daily and number 3,5,6 weekly! They recently released 9 which is a lighter weight version of 6 that I am extremely excited to try!!
Feedback
My only qualm is that their shampoo (number 4) is not pH balanced so I do not use it anymore. I’ve seen them respond to feedback (creating the lightweight version of 6) and I’m hopeful they can adjust their formula to make the shampoo as healthy as possible for our hair and scalps
I've used the no. 3 and while it made my hair softer, I have doubts about the ingredients. You will only see effects if you keep using the product but it's not meant to have the effects last a long time
Tested the no.7 oil but it made no difference to my hair.
