N.º 4 Bond Maintenance® - Champú

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

Hydrating Volumizing Shampoo

The Olaplex No.4 Fine Bond Maintenance Volumizing and Strengthening Hair Shampoo is a great shampoo for fragile, fine, thin, lifeless hair that pairs well with the Olaplex No. 5 Fine Bond Maintenance Conditioner! I have extremely fine but long hair. The bottle was small (8.5 FL oz) but the shampoo is highly concentrated with a thick rich texture. Although the shampoo had a thicker texture, it easily lathered in my hair with a light refreshing scent. It left my flat, thin, stringy hair more by volumized, hydrated, and it repaired my split ends/breakage without leaving my thin hair look greasy or weighed down! The Olaplex No.4 Fine Bond Maintenance Volumizing and Strengthening Hair Shampoo didn’t weigh my hair down but repaired my damaged lifeless hair leaving my hair softer, smoother, and shinier while removing product build up from my scalp. I love how gentle this shampoo made without harsh ingredients like parabens or sulfates while repairing my hair damage with a rich, moisture, repairing complex of low molecular weight hyaluronic acid that keep the hair soft and hydrated. This shampoo is highly effective for fine thin hair but I took a star off because I wish the bottles were bigger for the price because they are small and probably won’t last long for me since I have long hair but it still has a richer concentrated formula.

Frizzy Mess

This review is for the Olaplex shampoo/conditioner combo, as that is how I used them and don't know if one or both products was to blame for my negative experience. I'll start by saying that I love Olaplex No. 3 and wanted to love No. 4 and No.5. I have medium/normal curly hair that I heat style straight daily. In spite of that, it's in decent condition. I had some of the worst hair days of my life after using this shampoo/conditioner combo. I kept adjusting to try and make them work, but I was left with a dry, frizzy mess every time. I finally gave up and returned both bottles.

Great product

I have really super fine hair and I’ve used this product a couple of times and I can already tell a huge difference in how my hair looks and feels. I’m entering my 50s and my hair seems to be getting thinner so this product has really helped bring the life back into my hair.

A must use. Good..

This shampoo has a nice light smell. Gives you a little tingle sensation not bad. Feels good. Makes your hair soft & manageable. Using this shampoo has become a regimen..

Bonding

I received this free for my thoughts. This has a nice thick texture that has a really nice lather that smells nice. With the first use, I could feel that my thin strands felt a little thicker with less breakage and frizz.

Does not weigh your hair down

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.

HAIR TRANSFORMATION!

I have fine, fragile hair, and most shampoos either weigh it down, dry it out, or do absolutely nothing—but Olaplex No.4 Fine Bond Maintenance Shampoo is a total game-changer. It creates a rich, luxurious lather that deeply cleans without stripping or irritating my scalp. After each wash, my hair feels noticeably stronger, softer, and more manageable, without any heaviness or residue. It adds real volume to my fine hair, making it look and feel fuller, and gives a long-lasting, clean, refreshing sensation. Unlike other shampoos that leave buildup or make my hair limp, this one truly delivers. For the first time in a long time, I actually look forward to washing my hair. If your strands are delicate, fine, or easily damaged, I highly recommend giving this a try. This review was collected as part of a promotion.

Best shampoo I've ever used

I've used Olaplex products for 2 years and my hair has never looked better. They may seem costly but they are very concentrated so you use very little product.

Incredible breakage control, and shine.

Even though this was an incentivized review, I can honestly say I was floored by the results. After just one use, my hair felt dramatically stronger—dryness and brittle breakage came to an almost complete halt. My hair looked shinier, healthier, and fuller, and I started getting compliments at work, which hasn’t happened in a long time. It also gave my fine hair volume without weighing it down, and the clean, fresh scent is a bonus. Highly recommend this for anyone looking for serious breakage repair and beautiful shine!
