Good for reducing hairfall
I started using it after I had postpartum hair loss. I use both olaplex shampoo and conditioner. I did notice less hair fall after using it. My hair is very dry and fizzy. I didn’t find it changed anything in frizziness though.Quantity is okay and texture is good too. There is almost no smell.

    5.0 out of 5 stars It works over time for damaged hair, doesn't cause growth, not needed if hair is already healthy
    Reviewed in the United States on March 1, 2025
    Size: 8.5 Fl Oz (Pack of 1)Verified Purchase
    Good product - I started using a few years ago on my fried, bleached, breaking hair. In combination, used less heat and washed less often. After using for a couple years, I found that I no longer needed it even thought I do get highlights every few months. This lathers well, and a little goes a long way which is helpful for the high price. Very good quality. If you already have healthy hair, you could use it occasionally or it might not be worth buying - too much protein on already-healthy hair can actually cause breakage. Overall, it works over time and is a great product, but not really necessary if you have very healthy hair already.

    5.0 out of 5 stars Far Exceeded My Expectations
    Reviewed in the United States on October 24, 2022
    Size: 8.5 Fl Oz (Pack of 1)Verified Purchase
    I have no idea why I bought this but I'm glad I did. I was always cynical toward high priced shampoos. I would spend a bit more on special treatments but I always figured that shampoo is just get your hair clean so why splurge... Normal me would never spend $30 on a tiny bottle of shampoo. Life crisis me did. I normally use suave or pantene , just the deep cleansing ones, and since my hair has extensions in it I always had to use quite a bit to make sure it all got all over my head, through all the thick hair and I went through large $6 bottles rather quickly. I have bought, once or twice, expensive salon shampoos, Aveda, etc, but felt like I had to use a ton for them to actually get my scalp/hair clean. I was terrified this would last maybe 3 shampoos for me when I saw the bottle lol. The first time I used it, I used way less than I normally would of my other shampoos and it just kept multiplying itself, maintaining a THICK consistency, every time I ''shmoished'' it around my head, lathering it around very thoroughly. I could have used even half the portion I tried. It's the most incredible thick creamy sudsing, CLEANSING shampoo. It will probably last about 3 months and I'm fine with that at this price. It actually made my scalp and hair feel totally squeaky clean and fresh, without making it feel dry or tangled. It's a miracle you guys. Just buy it. Life crisis or not. Just buy it. lol - oh and a bit of background, I have professionally platinum balayaged hair, and even though the bleaching process is the best of the best, we still need to repair and help the hair, so for me it's all about the bonding products and they DO work. I've noticed my hair getting longer than ever because it was not breaking off, almost as long as my extensions now, but not as thick- yet, but still preserved what little I had left to grow it longer...then I graduated to the original and top product in that category (olaplex) and my blonde is now super shiny and feels like silky brand new hair. I really trust this will continue and even exceed in preserving my hair than the cheaper ''bonding'' products I was using. I use Oleplex 3,4, and 5 now and I will not go back to anything ever again. If you want platinum AND long healthy soft shiny hair...these three are what you need.

    I have diligently sought numerous products to enhance the health and vibrancy of my locks. Olaplex No. 4 Bond Maintenance Shampoo has emerged as a remarkable solution, garnering widespread acclaim for its efficacy and remarkable results.

    Restorative and Strengthening Formula:

    Olaplex No. 4 effectively repairs the damage frequently associated with dyeing and heat styling. Its bond-building technology not only fortifies hair from within but also ensures long-lasting resilience. Within a few washes, I observed a significant improvement in the definition and reduced susceptibility to breakage of my curls, thereby transforming the overall texture and strength of my hair.

    Gentle yet Effective Cleansing:

    Olaplex No. 4 provides a thorough cleansing without compromising the hair’s natural oils, which are paramount for maintaining hydration in curly hair. The gentle formulation ensures that my hair feels clean and refreshed, while simultaneously preventing dryness or brittleness, thereby preserving its natural bounce and shine.

    Color-Safe and Nourishing:

    A notable advantage of Olaplex No. 4 is its color-safe formula. It effectively preserves the vibrancy of my dyed hair, averting the premature fading that often occurs with frequent washing. My hair not only appears healthier but also retains its salon-quality color for an extended period.

    Luxurious Feel and Lather:

    The shampoo boasts a rich lather and a pleasant fragrance, transforming each wash into a mini spa experience. Its concentrated formulation ensures that a small amount suffices, providing excellent value and extending the shelf life of the bottle.

    Outstanding Results:

    Since incorporating Olaplex No. 4 into my haircare regimen, I have received numerous compliments on the remarkable transformation of my hair’s health and lushness. It has become an indispensable component of my routine, striking the ideal balance between strength and nourishment.

    Conclusion:

    Olaplex No. 4 Bond Maintenance Shampoo is an indispensable product for individuals with curls and color-treated hair. Its ability to restore, strengthen, and protect makes it an invaluable ally in maintaining beautiful and healthy curls. For its exceptional performance and transformative results, I wholeheartedly recommend it. Five stars!

    I was in search of a product to repair, strengthen, and nourish my thick, waist-length bleached hair. Olaplex No. 4 Bond Maintenance Shampoo along with the conditioner exceeded my expectations: my hair became soft with a healthy shine. I was so satisfied with the results that I repurchased both the shampoo and the conditioner. Despite the container holding only 8.5 fl oz, a little goes a long way -I only need to use a little more than a large coin-sized amount of shampoo to thoroughly cleanse my scalp.

    The shampoo has a delightful minty scent that leaves my scalp feeling refreshed after every wash. It effectively strengthens and repairs my damaged hair, making it feel healthier and more manageable. The improvement in my hair's texture and overall health is noticeable. I highly recommend this shampoo for anyone who is looking to nourish their bleached or damaged hair.

    I've been using Olaplex No.4 Bond Maintenance Shampoo for some time now, and it has truly exceeded my expectations. 🤩🙌

    First off, a little goes a long way, even for my long hair. This means the 250 ml bottle lasts much longer than expected. 🌊👌

    What really impressed me, though, is how effectively it cleans and hydrates my hair. 💧🌸 My locks feel refreshed, soft, and genuinely pampered after each wash.

    Another delightful aspect is the pleasant scent – it makes the whole hair-washing experience even more enjoyable. 🌺🌼

    Olaplex No.4 has certainly earned a permanent spot in my hair care routine, and I highly recommend it to anyone looking for a top-notch shampoo.

    You can feel the quality in this shampoo and yes, it’s not cheap but you are paying for a product that very little goes a long way.

    I use the size of a 20p piece in the palm of my hand and it lathers up into a luxurious foam. Hair is left shiny, smooth and my hairbrush glides through it.

    A 200ml bottle can last over 6 months if used sparingly, you do need to add a bit more water to get it to lather.

    Most beneficial when used with Olaplex No3 product first (pre shampoo treatment) and followed by No5 which is the conditioner.

    My hair was so dry and breakage was bad before using this product. I can now also go a day longer between washes, would recommend.
