N.º 4 Bond Maintenance® - Champú

Great For Color Treated Hair

Product was received as part of an educational promotion - Incentivized. The first time I used this shampoo I was amazed . It left my hair feeling very soft and clean. It cleans my hair without weighing it down or stripping it of my natural oils. After years of bleaching my hair I have yet to find a shampoo that cleanses my hair and retains moisture like this one! In between washes I am one to use a lot of products like oils, gels, and hairspray . This shampoo effortlessly cleansed my scalp and hair . Overall , I highly recommend this shampoo and will be purchasing another bottle.

It doesn't smooth the hair

Pros: It washes hair well. You don't need much, as it lathers easily. Cons: It doesn't smooth the hair at all. I bought it mainly for that purpose, and my expectations were as high as the advertisements suggested—especially based on the images (which they claim are not retouched). I don't know who created those before-and-after pictures, but they are definitely fake or heavily edited. My hair is natural—never dyed, never straightened—so there's no serious damage. However, after using this shampoo along with the No.5 Bond Maintenance Conditioner, my hair remained the same: puffed up and tangled. My previous cheap grocery store shampoo did the same job, but it was five times cheaper. Very disappointed. If you're looking for a shampoo to smooth your hair, I suggest trying another brand.

You must be patient with the result

After using a wide range of hair care products over the years, I finally decided to try the Olaplex Bond Maintenance Shampoo and Conditioner. These two products are part of the larger Olaplex system, which is known for its bond-repair technology designed to strengthen and protect hair from damage. While they are often used in salons, the shampoo and conditioner are available for at-home use, making them accessible for anyone looking to improve the health of their hair. First, let’s talk about the shampoo. The Olaplex No. 4 Bond Maintenance Shampoo has a creamy texture that lathers well without feeling too heavy. A little bit of product goes a long way, which is something I appreciate considering the price point. It cleanses the hair gently but effectively. What stands out the most is that it does not leave the hair feeling stripped or dry, which is a common problem with many shampoos that aim to deep-clean. Instead, the hair feels nourished even before applying the conditioner. The scent is mild and pleasant, not overpowering or artificial, which adds to the overall experience. One of the most noticeable benefits of this shampoo is how it helps manage frizz and dryness. After regular use, I began to see a difference in the way my hair responded to heat styling and brushing. It felt softer and more resilient. The shampoo is designed for all hair types, but it is especially beneficial for those with chemically treated, color-treated, or damaged hair. In my case, with color-treated hair that had become dry and brittle over time, the shampoo made a visible difference in the health and texture of my strands. Moving on to the conditioner, the Olaplex No. 5 Bond Maintenance Conditioner is thick and rich without being greasy or too heavy. Like the shampoo, a small amount is enough to coat the hair and distribute evenly. It detangles the hair quickly, making it much easier to comb through in the shower. After rinsing, my hair feels smooth, hydrated, and more manageable. Wh

The best shampo

I’ve been using the No.4 FINE Bond Maintenance Volumizing and Strengthening Shampoo, and it’s honestly one of the best things I’ve tried for my fine hair. From the very first wash, I noticed my hair felt fuller, looked healthier, and had actual bounce without feeling weighed down. It doesn’t strip my strands and somehow still leaves them feeling super clean. I also love how it helps with breakage and strengthens over time. The scent is fresh and subtle, which is perfect for daily use. A little goes a long way, and the bottle lasts a good while. If your hair is fine, flat, or fragile, this might be your new go to for me, my mom of course tried and her review was 5 stars so this is a must have just look my before and after stunning 😍

Fabulous product. Clean ingredients which are great for healthy hair.

Meh

I didn't notice a difference when using this product. Also it stinks.

I love this stuff!

My hair definitely loves this product. Olaplex No 4 Bond Maintenance Shampoo gives me shiny and thicker-feeling hair. It leaves my hair fresh and manageable for days. And only a small amount is needed, so the 3 ounce bottle lasts for a really long time. I use it with the No 5 conditioner and the results are excellent.

Smells great

Olaplex No. 4 Bond Maintenance Shampoo is a highly regarded product designed to repair and strengthen hair using Olaplex’s patented bond-building technology. Suitable for all hair types, including color-treated and chemically processed hair, this shampoo effectively restores broken disulfide bonds, enhancing hair’s overall health and resilience. Users appreciate its concentrated formula, noting that a small amount produces a rich lather, making the product long-lasting and cost-effective. Many report noticeable improvements in hair softness, shine, and manageability after regular use. However, some individuals with fine or low-porosity hair have experienced dryness or increased shedding, suggesting that results may vary based on hair type. Overall, Olaplex No. 4 is praised for its ability to revitalize damaged hair, though it’s advisable to consider your specific hair needs and possibly consult with a hair care professional before incorporating it into your routine.

Texture feels like heaven

Product was received as part of an educational promotion - Incentivized. The consistency is thin enough to do the job of shampooing my hair, ridding my scalp of the residual products, the first time without multiple washing. It left my hair feeling very soft and clean. It cleans my hair without weighing it down or stripping it of my natural oils. I have yet to find a shampoo that combats the dryness of my hair and the fine texture simultaneously. I use a lot of products to lift my hair, providing texture and volume. That includes gels, texturizers, volumizers and the like. This builds up the hair texture, giving it a sticky and tacky residue that is hard to get rid of. That is until I found Olaplex shampoo. It just cleaned my hair, going down to the roots of the hair leaving it clean. My daughter even used this shampoo on one of my wigs at home, the shampoo has softened and lengthened the wig.

This never disappoints!

This is a favorite gentle shampoo for everyone even without using all the other products in the bonding regimen! I will keep this always in the rotation. A little goes a long way for my fine thin color treated hair.

Super shampoo

I recently tried the Olaplex No.4 Bond Maintenance Shampoo for Fine Hair, and I have to say — I’m seriously impressed! As someone with fine, delicate strands, I’m always cautious with shampoos that claim to “strengthen” or “repair” because they usually end up weighing my hair down. But this formula? It's a total game-changer. It’s incredibly lightweight, yet still delivers a deep, satisfying cleanse without stripping my hair or leaving it feeling dry. My scalp feels refreshed, and my hair feels clean but not squeaky — just perfectly balanced. After just a few washes, I’ve noticed that my hair looks shinier, feels bouncier, and has more volume at the roots. Even my ends feel healthier and less brittle. What I love most is how it strengthens my hair without sacrificing softness or movement. It somehow manages to fortify each strand without making it stiff — which is no small feat for fine hair. And when I pair it with the Olaplex No.5 conditioner? Pure magic. My hair feels silky, smooth, and looks like I just had a professional treatment done. If you have fine or easily weighed-down hair and have been hesitant to try bond-building products, this shampoo is the perfect starting point. It delivers results without compromise and has definitely earned a permanent spot in my haircare lineup!

100% The best

I’ve used many other shampoos over the years but this is the best by far for condition and volume absolutely great results from the first wash
