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.

It’s a different way to care for my damaged, platinum blonde hair. It’s considered a pre-wash treatment. I like that I can quickly use in the shower and it only requires 3 minutes. It’s different because you wet your hair first, then apply Olaplex N3 Plus and leave it on for 3 minutes, then rinse and shampoo and condition as normal. It’s designed to keep working and helping your hair for up to 3 washes and because I don’t wash my hair but every couple days, it’s a treatment I only need to use about 2 to 3 times a month. It’s an upgraded version of Olaplex N3 because it’s also going to help your hair in the future, not just past and present damage. I noticed after using even 1 time that my hair was softer, smoother with less frizz. It also helped my wavy hair look healthier and more uniform instead of a scraggly, frizzy mess. If you have shorter hair to your shoulders or shorter, the 100ml bottle will last you several treatments. I have shoulder length hair and have been able to use 3 treatments and about 1/4 of the 100ml bottle is used. If you have longer or thicker hair I would recommend buying the larger size.

love this oil, which opened me up to the brand overall. high-quality and seem to really make a difference in my hair health. you only need a few shakes of the oil to apply to lengths of damp hair, so it lasts a while.

This just didn’t work for me. I had to use a lot of product each time just to fully coat my hair (long, thin hair) which made it feel wasteful fast. While my hair felt super soft and smooth right after rinsing in the shower, that softness completely disappeared once I followed with shampoo and conditioner per the instructions on the bottle. After drying, my hair honestly looked the same or sometimes even worse than before using it. I also noticed there are a lot of added fragrance ingredients, which felt unnecessary for a repair treatment and made me question the other ingredients and their necessity as well. Overall, it temporarily smoothed my hair, but there were no lasting results.

I have tried so many hair oils over the past 10 years. I have tons of favorites tons of hits and tons of misses and I would say that this hair oil falls in between a lot of categories. If you have oily fine hair similar to myself this oil is just super light. It’s lightweight goes on and dries very quickly so that’s nice but I don’t notice the bonding properties that are supposed to happen with it. It’s supposed to reduce frizz and flyaways, and Is a heat protector up to 450°. You would have to use a ton of this oil for it to be a real heat protector so I don’t count it for that and I don’t notice a ton of reduced frizz.

Honestly, I wasn’t expecting a miracle, but Olaplex No.3 surprised me. My hair feels softer, stronger, and much less tangled after using it regularly. It’s one of those products where the results build up over time rather than overnight. A little pricey, but for me it has been worth it

I’ve honestly never been a hair oil girly but this is amazing! I have naturally oily hair yet it didn’t leave a heavy or oily look to my hair. It gave me a really nice shine and smells great. I will definitely be repurchasing this.

I really love this oil; already repurchased it several times and will continue doing so. It leaves my hair with a beautiful shine, feeling nourished and not heavy like other hair oils. A little goes a long way. Smells super pleasant, not overpowering at all. Only downside is that it leaks sometimes when traveling, so I always put it in extra paper towels and zip locks.

I got this in a hair health kit from Sephora and was shocked at how small the bottle was. Once I started using it, I realized it was small but mighty and would last forever. Great smell and really tames down the hair.

I think everyone can agree that Olaplex smells amazing. This shampoo actually gives more than you'd think and even a small dollop can produce so much shampoo and conditioning in the shower. I definitely feel a difference when using the shampoo for my dry hair.

OLAPLEX No.5 Leave In Moisture and Mend Leave-In Conditioner is a great staple piece to keep around and in your travel bag. It could easily be used daily or with each shampoo if you need an extra layer of conditioner and repair cream. I prefer to use mine after applying a glaze to my hair. The glaze doesn’t have as nice of a finish-feel as freshly conditioned hair, so I use it as a finishing touch and it works really well. I haven’t used many OLAPLEX products, but this has been a good place to start!

I’m in love with this! Ever since I found it, I can’t imagine my hair routine without it. It makes my hair incredibly soft and silky. I’ve tried other products after finishing it, but nothing even comes close. Truly a must-have!

I love OlaPlex. I’ve tried several of their products and they all work very well. My hair looks great. I think it is a little high price but worth it for what you’re getting I would recommend it. And would buy again.

I’m not totally sold on this product yet. I have incorporated it into my routine to give my scalp and hair that extra clean but I feel like it makes my hair oily. I definitely have to wash it more often when I use it.

I <3 this shampoo so much; it came highly recommended by a friend who is a celebrity colorist. It's made my hair so much healthier and shinier. Just a little bit of product create a lot of lather. I also use the conditioner and have the smaller bottles for travel! Need to explore the rest of the product line.

I have used the hair mask and hair oil and I've found that they work really well. Especially the hair oil! I've purchased multiple bottles and have recommended it to a bunch of my friends. It works great esp since I have a dry scalp.

Didn't see much of a difference when I used it a couple months ago.I've have curly hair that I dye often, so I really needed something to restore my damaged hair. Maybe I'll get back to the habit of using it and see if there's any change. It could also be that I'm just using the shampoo and it would be more effective to get their conditioner as well. They're really hyped up and at this price point, I want it to work for me.

I am familiar with some Olaplex hair products and am glad to see that they are continuing to extend their line of bond building hair products. No5 is really easy to use and pairs well with other hair products I am using. I think of it as a leave-in that will give me that extra help that my hair desperately needs. My very fine hair does well with just 1 pump on my clean, damp hair. It’s a creamy consistency that is thicker than a hair serum and daily rinse-off hair conditioner but not as thick as a rinse-off hair mask. I like to apply a pump on my hair between wash-days by focusing on the areas that need it most like the ends and pieces around my face. I like the scent is not overpowering and is what I would consider a unisex scent. I like that it’s not oily or greasy on my hair and it doesn’t make my very fine hair feel weighed down or heavy.

I swear by the N3 hair mask. I can’t speak to other pieces of the routine, but the mask, only once a month, has made a huge difference in my color treated long hair! The small bottle may be deceiving but I don’t find I need to use much at all to get great results.

This leave in conditioner is alright. There are other brands preferred to this. I’m using it because I have a few small containers of it but my hair is also short. I might recommend it. Still unsure.

I have long hair that is on the thin side. I thought it didn’t need a lot of hydration but I color my hair, that wavy. I tried Olaplex before, but it made my hair feel more dry after. I can say Olaplex 5, didn’t make my hair feel stiff like hay after but instead made it easy to detangle, and soft. I always smell my products before applying them, and I like they keep the traditional fragrance. I like the fragrance and smells I little bit of fresh mint, mixed with rosemary. Rosemary kinda smells like citrus and sage, and the number one fragrance I always go for is citrus. When applying the leave-in conditioner to my hair I learned I only needed to use one pump amount for my left and right side. The consistency looks thick but spreads easily through my hair. I noticed some products if my hair is damp, the top turns stiff, but the leave-in didn’t. The Olaplex didn’t leave my hair feeling weighed down or greasy, but I liked the results a little more when there was less product on my hair.
