I’ve heard a lot of hype about Olaplex (both bad and good), but never gave it a try myself until recently. I used the No. 4 Bond Maintenance Shampoo in conjunction with the No. 5 conditioner.

The ingredients list is large – there's no way around that – it's massive, but contains some natural ingredients (banana fruit extract, rosemary leaf extract, sunflower seed oil, etc.) as well as biotin, panthenol, and glycerin. I found that it lathered the same as any other sulfate-free shampoo and rinsed out easily. I felt comfortable using it on coloured hair and didn’t notice any stripping or fading. My goal was to see my hair look a bit more rejuvenated. Recently, it has been dry and dull, with a lot of split ends and heat damage. My hair is just naturally on the drier end and prone to frizz, simply the way it’s always been and likely genetics. I also do heat-style my hair 1-2x a week, which doesn’t help the situation. After using this consistently along with the No. 5 conditioner, my hair felt softer to the touch and appeared to be shinier (and as a result, healthier). It didn’t magically “heal” my split ends, but it softened the look of them and made my hair look more cohesive, rather than looking like a bunch of distinct, ratty strands. I don’t know if the difference was dramatic enough to justify the high price point of this shampoo, but it’s a very nice luxury to treat your hair to occasionally. A small amount does go a long way, so it may be more justifiable to splurge on a bottle.

There was a great promotion going on at our local hair salon supplier store so I purchased both the shampoo and the conditioner from Olaplex in the salon size, which is 2000ml. I had received also samples of Olaplex No. 4 in the regular size in the past. The great news is that both 2000ml products lasted me for over a year. Please note I am not a hair stylist, I purchased both for personal use. Now the bad news is, I was never impressed with these two products. I have colored hair and I just don't feel Olaplex in general ever improved my hair in any way, whatsoever. I never felt my hair was healthier or moisturized with Olaplex, actually quite the opposite. If you are planning to purchase any of these two products in the salon size, apart from suggesting to first ... MoreThere was a great promotion going on at our local hair salon supplier store so I purchased both the shampoo and the conditioner from Olaplex in the salon size, which is 2000ml.

If you are planning to purchase any of these two products in the salon size, apart from suggesting to first try the product in a smaller size and making sure you like it first and not making the mistake I did with buying the salon size bottle, I would suggest asking for an additional pump hence I had issues with the conditioner pump. I am still happy to give Olaplex a second try if the brand will be coming out with new products in the future, but I am not a fan of their perfector, shampoo, and conditioner hence the 3-star rating.

Game Changer!

I've had the pleasure of using Olaplex No. 4 Shampoo as a part of my haircare routine, specifically hair recovery. A few years back I was experimenting with different hair colors at home and decided since I have such healthy dark brown hair I would bleach it so I could use unconventional colored hair dye and basically even though I followed instructions and watched tons of videos I ruined my beloved hairs texture and bond. I've been using countless different products to help me with bond restructuring and this Olaplex No 4 has been a game changer for my hair. My hair is normally non porous, dull, and dry but with Olaplex my hair is drastically changed that. I now have the most shiny, revived, and super soft hair I am so grateful.

I have pretty long hair and normally use tons of shampoo but this No 4 was different. It only took a small amount of product to produce huge amounts of lather so I feel this shampoo will last longer also. I did use this with the Olaplex No 5 conditioner as a system . If you have damaged, dull or unhealthy hair this is a must!

Great for color treated hair

Gifted by Olaplex in exchange for my honest review. Formulated with Olaplex's patented Bond Building Technology™, this reparative shampoo is designed to hydrate and nourish hair while supporting bond repair to help prevent further damage and split ends. This nourishing shampoo is gentle and effective and in my opinion, should be used more as a treatment to aid in reducing frizz and breakage and other signs of damage from color, environmental stress or any causes of dryness. For me personally, this has been an amazing addition to my haircare routine and has helped my slightly dry and damaged hair to look much more healthy and shiny. My medium, wavy hair is both color and bleach treated and so the texture was a bit rougher and more dry than I'd prefer. After using ... MoreGifted by Olaplex in exchange for my honest review.

My medium, wavy hair is both color and bleach treated and so the texture was a bit rougher and more dry than I'd prefer. After using this shampoo once every week or so, it looks significantly more healthy, feels softer and smoother and my color looks more vibrant too. The shampoo itself seems concentrated so a little goes a long way. It smells lovely and lathers well giving me a great experience and leaving my hair looking and feeling cleaner and healthier with each wash.

Low porosity/Coil/4C-ish hair girlies, stay AWAY!!

I will leave this review on all the products I used that caused HUGE CHUNKS of my hair to fall out on wash day after using them as instructed.I get a silk press about 2-3 times and year and before using their products my hair was mid-back length, thick, with voluminous layers.However, due to low porosity my hair would feel dry very quickly and needed lots of moisture and oils to stay hydrated.The least manageable part was how the dryness let to many split ends despite regular trims.With static due to dryness, the ends would get knotted even with wide tooth combs or brush detangling brushes.And because of those small knots, certain hair strands would snap or get tangled up even more.Even though I had lots of volume and long hair, the bonds were weak and i ... MoreI will leave this review on all the products I used that caused HUGE CHUNKS of my hair to fall out on wash day after using them as instructed.I get a silk press about 2-3 times and year and before using their products my hair was mid-back length, thick, with voluminous layers.However, due to low porosity my hair would feel dry very quickly and needed lots of moisture and oils to stay hydrated.The least manageable part was how the dryness let to many split ends despite regular trims.With static due to dryness, the ends would get knotted even with wide tooth combs or brush detangling brushes.And because of those small knots, certain hair strands would snap or get tangled up even more.Even though I had lots of volume and long hair, the bonds were weak and i wanted to strengthen them.Therefore, I purchased Olaplex hair kits that would help with the issues I was experiencing.However, Olaplex [Falsely] advertised their bond repair products, saying that it will support strengthening hair.But the absolute opposite happened. Their products as a whole dried my scalp so much that it looked like I had psoriasis.After the first application, of numbers 3, 4, 5, 6, 8, 9, rinsing when the instructions said rinse, and leaving-in the products that were marked as leave-in, I would have never guessed that the moment I rinse my hair, so much would be just dropping off my head.I thought, maybe it's the weather, and went on with using the products. But by the time i made it to wash day #2, my scalp had gotten SOOO much more dry than it has ever been before.And it itched like crazy. Again, I thought it was the weather, and kept using them in the prescribed order from the instructions on each bottle.But before i could even realize that the products were killing my hair from the root, my scalp had become so irritated that it had dried into extremely huge flaky layers.And no matter how much I washed and scrubbed my scalp, it didn't help. I have never had issues with dandruff and now suddenly from the nape of my neck to my front edges, it was hard cakey dandruff.I had to clarify my hair from their products with warm white distilled vinegar water. Only then, the the flaking stop.What's even worse is the state of my ends, they look fried and feel even more brittle. they snap immediately just combing through with my fingers.I kept losing so much hair that I now have BALD SPOTS.My hair is so light it's traumatizing considering how much body and life there was to it before I started using Olaplex.It has now been 3 weeks since I stopped the product and went back to my old routine but every time I go under the showerhead, I still shed like cat's fur in spring.My hair is fried an unmanageable. I have no other option but getting a bob chop at ear length. The damage is ridiculous.I am convinced 99% of positive reviews were PAID for, and many are bots!!! There is no way this product is not killing people's scalp.They're trying to induce dependency and LIED through their teeth about their products being for all hair types.A LIE, it's all a LIE!! DO NOT BUY!Especially if you already have dry hair, low porosity, frizzy hair, thick coils and dense volume.Their products might work for straight and overly oily scalps, but it was in no way tested on people with my type of hair and dry scalp.

My new favorite shampoo

I was gifted by Olaplex the No. 4 Bond Maintenance Shampoo for free, in exchange for my honest review of the product. As a first time user, of the Olaplex product line, I was not quite sure what to expect. My hair is very long, frizzy, and naturally wavy. I use heat on my hair as part of my daily hair routine. So I am always worried about damage like split ends and breakage. I was pleasantly surprised to find, that after using this product for the first time, I could see and feel a difference in my hair. The shampoo has a light fresh scent, and is thick in consistency. I also found that, unlike other shampoo products, I did not have to use a large amount to get a great lather. After washing my hair, with like warm water, I was able to see a difference while it was ... MoreI was gifted by Olaplex the No. 4 Bond Maintenance Shampoo for free, in exchange for my honest review of the product.

After washing my hair, with like warm water, I was able to see a difference while it was still wet. I blow dried my hair and unlike with other products, my hair dried much quicker. I instantly could feel and see a difference in my hair. It was overall smoother and had a nice lustrous shine. My hair looked overall healthier than it has in a good while. Best benefit of all, is that my split ends were not extremely visible. I am extremely satisfied with this product, and I am looking forward to trying other products from this brand.

The BEST

I’ve been using the Olaplex range for several years and it’s completely changed how I care for it. I don’t need to wash it as often as I did and it feels stronger, looks shinier and feels amazing.If you’ve not tried Olaplex your hair will thank you as makes brushing and combing so much easier, mine doesn’t tangle as it used to before. It was an absolute nightmare. It would tangle and be painful to comb out and even using a tangle tease brush it would still hurt and I’d lose so much but that changed when I started using the shampoo and conditioner. They both are thicker products and if used correctly a bottle can last an awfully long time.Do yourself a favour and buy the Olaplex range and use religiously and you’ll find you’ll not need to wash it so often.

I have fine hair and lots of it and these products have transformed it.I love how my stylist sees how it responds to bleaching and heat and its all because of this range of products. (They use RedKen in the salon but I take my Olaplex to use) I will continue to use Olaplex as it’s completely transformed how I treat my hair. I don’t need to dry with a high heat setting and if I’m straightening I can do my whole head in less than 5 minutes. (My hair is about 16” long and layered)I cannot recommend Olaplex enough and urge everyone to at least try it out.

Waste of Money

Take this review for what it's worth: this is about *MY* hair - your mileage may vary.Does not live up to the hype or claims. Definitely not worth the price. Actually would not even use this (or the Nº.5 Bond Maintenance Conditioner) as "regular" shampoo/conditioner, even for a cheap price.Review:Does not distribute evenly so is difficult to spread the lather around. Have to use a bit more product than other shampoos for the same amount of hair. After rinsing, my hair doesn't feel clean. It doesn't feel "dirty," but with other shampoos I can tell my hair rinses clean from whatever products were on it. I do not get that feeling from this shampoo regardless of how much I use. I have used two litres each of this Nº.4 Bond Maintenance Shampoo and the Nº.5 Bond ... MoreTake this review for what it's worth: this is about *MY* hair - your mileage may vary.Does not live up to the hype or claims.

I have used two litres each of this Nº.4 Bond Maintenance Shampoo and the Nº.5 Bond Maintenance Conditioner and notice absolutely no difference. Granted, my hair is not easily prone to breakage, but there is some frizz from mid-length to ends (see "Context" below) and there has been no noticeable improvement in either the strength or appearance of my hair when using Olaplex products. (I tried several Olaplex products during the same time period and used them *exclusively* to control for other variables and objectively judge whether there were any benefits. There were not. During the trials of 2L each of Nº4. shampoo & Nº5. conditioner, I also used multiple containers of each of the following: Nº.0 Intensive Bond Building Hair Treatment, Nº.3 Hair Perfector, Nº.6 Bond Smoother Leave-in Styling Treatment, Nº.7 Bonding Oil, Nº.8 Bond Intense Moisture Mask, Nº.9 Bond Protector Nourishing Hair Serum, and the Volumizing Blow Dry Mist.)Context:My hair is very fine/thin but there is a LOT of it, about three times the average number of follicles (according to multiple hairdressers/stylists and one dermatologist) and takes about five hours to go from towel-dry to completely air-dry in ~60% humidity. It's about four inches past my shoulders and is largely straight with minimal natural body waves. It is not damaged but for a few years now it's been mildly frizzy from mid-length to ends. (Am in my early 50s and I, my GP, and hairdresser/stylist who is the same age as me, suspect it's probably hormonal.) Have tried numerous products to reduce the effect and smooth it out. Not found a solution yet. Not prone to breakage easily but will not hold an up-do when clean and dry because it's too slick; it has to be dirty or coated with dry shampoo and/or a sticky product first. But, bizarrely - and impossibly - if you so much as breathe on it the wrong way when it's dry, it will tie itself into knots. Literally tiny knots and no one ever believes me until they see it for themselves. Windy weather is painful to recover from if I wear it down and free-flowing. I have almost no grey hairs; my natural color ranges from medium-light to medium-dark brown hair. I get a professional cut with some lowlights plus a few highlights around my face done every 10-ish weeks. I wash and condition it almost every morning since just one night's sleep causes it to look greasy regardless of pillow type or covering. I blow dry about 75% of the time (with a Harry Josh dryer) but not all the way dry every time.

Why I keep repurchasing this

Unfortunately, I am a product junkie and I jump from product to product regardless of how effective the previous one was. I also have terrible-quality hair (extremely fine, thinning, coarse, freezy, etc) which drives me to buy even more products. Bond builders have been a game changer for my terrible hair and I can safely say I have tried them all that are out there. Nonetheless, this shampoo I keep returning to as I feel nothing can beat this. I used Olaplex products almost uniquely for 2 years and they saved my hair. However, because of my hair texture which needs both intense protein and also hydration/moisturisation after two years of intense use, I noticed a lack in hydration and moisturization. So I moved to use the Olaplex shampoo and conditioner on the week ... MoreUnfortunately, I am a product junkie and I jump from product to product regardless of how effective the previous one was.

So I moved to use the Olaplex shampoo and conditioner on the week I die my hair and moisture or the equivalent of 3 washes and then another shampoo and conditioner/hair mask that are mainly moisture focused with min protein. After every 3 washes, I also do a deep clean and use a bond builder (separate review). The tow years of use of solely these products and then moving to this combination doubled my fragile hair that are now far stronger.
