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.


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.

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've only managed to use this product around 3 times before running out of it (I have rather long hair), but I can confidently say that I really did see and feel a difference after use! My hair is damaged between dying it and the heat from hot showers and outside weather, so it often feels brittle and looks not too great. However, after using Olaplex No.3 Plus, my hair has totally felt stronger and looked like it's actually not about to all fall out! It also looks smoother and softer, and I haven't experienced much hair loss. The smell of it is another benefit- for it being a pre-wash product, the scent sticks to your hair throughout the day. The patented Olaplex Bond Building Technology has truly come in clutch this time, and I'm very much looking forward to rebuying this product and using it!

First things first, I am in LOVE with the way this OLAPLEX shampoo smells. I found that the scent is very luxurious and powerful in my hair. Moving onto the lather, I was very pleased to see that the spread-ability was up to par with how I like my shampoo being dispersed on my scalp. It gave a nice foam, and when it came to rinsing it off, my hair and scalp felt pleasantly clean after. Since I have 2A hair, I like products that don't weigh my hair down but instead enhances and gives body to my waves. With this shampoo, I found it doing just that! When paired with the conditioner, I was even more impressed with how suitable this shampoo is for those with wavy/curly hair.

This OLAPLEX conditioner has done nothing short of ensuring that my mid-lengths to the ends are soft, hydrated, and wavy. I'm really happy with how luxurious it smells, as well as how the scent lasts long in my hair- I've gotten way more compliments than usual from how good my hair smells! I'm someone who feels the need to shower everyday due to my hair feeling dry, but surprisingly enough with this conditioner, I managed to stretch out the in-between time for my shower to 3 days. That in itself is a huge accomplishment for a product, IMO! Moreover, this conditioner has given body to my waves; I did wish that it tamed down the frizz, but I can't complain too much since it does a great job with enhancing my curls.

As someone who constantly seeks out new scents that are long-lasting and are refreshing to smell, Olaplex has really hit the mark with this perfume mist. It's very 'salon-fresh' and can be used anytime throughout the day, morning or night, to uplift the mood and revitalize the senses. The scent profile of this mist centers around the perfect zest of grapefruit citrus complementing sugared mint, which in my experience, is the bolder smell of the two. Other notes, such as ginger and sage, are also present, adding a warm and clean depth to this mist. Overall, the combination of all these smells is genuinely a match made in heaven. This mist is also lightweight and quite easy to layer, but I found myself spraying the perfume mist solo just so I could appreciate it.

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.

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.

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.

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.
