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've been using Olaplex as a bond builder on my hair ever since I started bleaching it about 3 years ago. It's stayed in great shape (according to my hair stylist who had recommended it), and I use it as directed! I know there has been some recent controversy with the side effects of the product, but I personally have not faced any of those, and I've been using a variety of the products too (I think I have 0, 3, 4, 5, 6, 8, and 9 all in my closet right now). My favorite is number 8 - that moisture mask is amazing! I do not see a noticeable difference after using most of the other products, however. Especially the toning shampoo - it does not tone as well as other purple shampoos I have tried. But I'm sure it works differently on everyone - my hair is naturally a mid-brown. There are of course so many products in the system and different directions for each, which can be complicated and time consuming. Sometimes I wonder if it would be cheaper to me to just go to the salon every once in a while and get a treatment for hair damage, because Olaplex products certainly are not cheap, rather than do these time consuming hair masks once a week.

I know that a small part of the population have had an allergic reaction to Olaplex. What product doesn't have people who are allergic? You may not know until you use it if it works for you, but hopefully you get the benefits I have gotten. I use #3, #4, #5, #6, #7, and #8. Maybe even #9. I use the purple version of #4 to help tone the brassiness in my money piece. My bff is a cosmetologist and she started raving about Olaplex as soon as it came out. I had no idea what she was talking about because Olaplex wasn't available for regular people to buy. I had to visit her in Colorado to find out the magic that is Olaplex. You definitely need to use it regularly to reap the full benefits. I am brutal to my hair. I bleach it, dye it, use heat at times, etc. This is what I can tell you... If I didn't use Olaplex, my hair would be straw. It's a good thing I live in a desert climate. Olaplex helps a ton. I'm so glad I have access to it now just like the professionals. If I didn't like Olaplex, I would not be writing a review like this. You can see my honesty in other reviews. If I don't like something, I'll tell you. I do think it's worth the money. Do I think you need all of the products? No. I don't need my phone anymore when looking at the numbers to figure out what's best for me, as I used to stand in the aisles trying to figure out which products would be necessary for me. I got the bonding oil as a gift. I have never used an oil before on my hair and had I not gotten it, I wouldn't have bought it. It's nice though. It didn't weigh my hair down. If your hair is dry, I think you could use #3, #6, or #8. It definitely depends on what you like and what you need. If you're blonde and trying to get the brassiness out of your hair, the purple shampoo definitely helps neutralize the yellow. It's worth the hype but give it time. Your hair may feel awesome initially but it does take some consistency for you to get the full effect.

My go-to for when I'm blonde! I used to bleach my whole head + straighten my hair every day in high school, so it was terrible — fried, short, breaking off, etc. I switched to Olaplex and overtime, saw a huge change in my hair! Still used tons of heat and saw a difference, but once I cut down on that my hair was the longest and healthiest its ever been. If you aren't blonde, it might not work as well, as I'm now 50% brown and growing out my natural hair, and I don't find I need this/it doesn't work as well on me. I still LOVE the leave-in + oil for blow outs, and the mask is my go-to after lightening or color services!
Lo mejor para reparar tu cabello dañado, yo tenía las puntas un poco feas por una mala pintura pero me reparo totalmente el cabello y no tuve que cortarlo, fue lo mejor!
I think Olaplex is over-hyped. I know a lot of people get great results from their products, but they were only ever okay for me. I don’t love some of the chemicals they use, either.
I use the No. 5 and No. 6 and I really enjoy them. The shampoo is moisturizing and also clarifying. I have been using it on and off for over year now and I still have not finished a full bottle. It requires such little product to clean your hair properly. The conditioner is good, but it's not revolutionary, in my opinion. I would definitely recommend the shampoo if you have thinner hair.
I'm a big fan of the N3 and N6 products. They work great in repairing and protecting my hair. I do have the shampoo and condition (N4 & N5). I use these often but not all the time because I found my hair to become rough if using it everyday.
I recently went double process blonde. I still have tons of breakage, but I’m sure it would be worse if my stylist didn’t use Olaplex. He uses No 3 and finishes off with No 9. I use pre-treat my hair with No 0 for 10 minutes at home then go in with No 3 for another 10 minutes. I wish it didn’t have to take so long, but I have to do it. I went through half the bottle of No 0 (I have a lot of hair, plus my hair is porous because of the bleach) my first time using it, which is kind of annoying. There are other brands knocking off Olaplex now, like Redken and L’Oréal. I would be interested to try them, just to feel what the difference is. The Redken is about the same price as Olaplex, and L’Oréal is definitely cheaper.

I use pretty much the whole line of Olaplex products from the shampoo and conditioner to the oil and the masks. I feel like it works really well especially for color treated hair. You really don’t need to use very much of the product at once, so I feel like it lasts a long time and is worth the price. I have blonde hair, and I just use the regular shampoo and conditioner rather than the purple one fyi.
Pricey but so worth it and it does not take much. The No 3 is the OG game changer. I have fried my hair with heat and also bleach it - so this stuff is my holy grail and saving grace. I have tried the shampoo and conditioner in addition to other Olaplex products, but if you are to buy only two musts - it’s the No3 and the bonding oil.
Didn't love it! Has a lot of hype but didn't do much for my hair. I also think it's kind of confusing looking to figure out which would actually be best for you or which numbers to mix. not for me.
Look I’ve been at nice hotels and I’ve online shopped after drinking too much so I know good shamp and condish. This is my all time fave. It’s cool looking it smells nice and feels cool. It’s the best. All others are garbage. Sorry classic or trash world and they are on top.

I have N6 and N9 and I love them. They are great for my frizzy hair! I really didn't want to like them because they're fairly expensive, but I can't go back to anything else after using them.
The brand itself has really great products, if you are educated on how to use them properly. I gave 4 stars mainly because of the price, but overall, the products really help if you’re someone who has color treated hair or heat damage. I would think of this line as something you use in moderation, and not something to use everyday.
Good design but not worth the money. It gave me minor rash.
I used this product before at the same Dumbo, Brooklyn apartment of that said person I was dating with the Dr. Jart products. I did use it several times but I found out that this product makes you lose your hair through the Reddit community.

Do not use this product because apparently it makes you lose hair.
Olaplex saved my hair! I have been doing vibrant colors for several years and the constant bleach to my hair has definitely taken a toll. Using olaplex has revived the shine and health to my hair. The nice thing is you dont necessarily need to buy the whole line to reach this either. I started out with the shampoo and conditioner and that was enough to revive my hair's health.
Feedback
The conditioner is hard to get out of the bottle unless you store upside down. I would love a bottle that squirts from the bottom.

I enjoy olaplex products, specifically the hair masks. My hair feels so soft after using them. I also love the clarifying shampoo
Feedback
The product sized tend to be on the small side, especially for the price. Overall it’s an effective product so I think it’s still worth the price.
Huge user of the oil for my bleached and dyed hair. Olaplex absolutely saved the texture of my hair.
I use #6, #7 and also #4P occasionally (purple shampoo). I love using #6/7 together (I mix a dime size of 6 with a few drops of 7) after I towel dry hair in a turban. It makes my hair so so soft! Also #4P is pretty good but I do not use it that often. I only wash my (silver/grey) hair 2-3 times a week and probably use 4P once a week. It's good but I think my favorite purple shampoo may still be Fanola but this is a close second. Buying the other products is a bit out of budget for me but I decided to splurge on these to get the most bang for my buck and I do love them. Maybe one day I will get the shampoo and conditioner too.
Feedback
Definitely recommend #6 and #7 to be used together!
