N°. 4 Fine Bond Maintenance – Shampoo

It works and it smells great

Olaplex No.4 Bond Maintenance Shampoo is one of those rare products that truly lives up to its hype. From the first wash, it makes hair feel stronger, smoother, and more manageable without weighing it down. The formula lathers beautifully with just a small amount, so the bottle lasts a long time, and it has a clean, refreshing citrus scent that feels uplifting and salon-like. What sets it apart is how it repairs and protects damaged strands—especially helpful for color-treated or heat-styled hair. Over time, it noticeably reduces breakage and frizz, leaving hair softer and shinier with a healthy bounce. While it’s a premium price point, the results make it worth the investment for anyone serious about hair health. It’s a game-changer in a haircare routine.

Great to shower train hair!

I received this as a part of an educational promotion and I couldn’t be any happier! I used to be someone who washed their hair EVERY single day and saw it was causing a lot of damage to my hair but when I would try to wash it every other day I noticed my hair would be oily fairly fast. I use this product every other day and and my hair was still not oily for the second day. I would apply a dime size amount on my hand and it would give a great lather it smelled is very fresh Kind of like an expensive hotel shampoo lol(wish it smelled more fruity). I don’t recommend this product though for every day use as it does dry out your scalp move it every day. I believe it works best every other day as I mentioned, it really prevents your hair from getting oily, and my hair has looked shinier than ever. I would definitely buy and recommend I loved it!

Crossing my fingers that I’m losing less hair!

I was pretty excited to get this shampoo as let’s face it, we’ve all heard the hype about Olaplex. I’ve moved to a new city recently that I think might have harder water than I’m used to, because I’ve been experiencing some extra hair loss. I already naturally have very thin, fine hair, so losing more of it is always the worst. I was pretty excited to see that this shampoo was specifically for fine hair, since some shampoos tend to weigh fine hair down. This is an interesting product because it definitely doesn’t lather as much as my usual shampoo. I’m used to a pretty strong lather. Like noticeable bubbles in my hair lather. For this product, I apply some in the palm of my hands and rub them together and I see some bubbles and suds, but not much, and as soon as I apply it to my scalp, they pretty much sink right in and disappear. I’ve included a picture of my scalp directly after applying the shampoo and you’ll see what I mean- you can’t even tell it’s on there, zero suds. This took a little getting used to for me, because I think I overcompensated and used extra product, because I was always looking for that lather that I was used to seeing. Once I realized what I was doing, and that it was cleaning my hair just fine without all the extra suds and bubbles, I scaled back how much product I use. So yeah, even though it might not be super bubbly it definitely did a good job cleaning my scalp without weighing down my hair. I’ve been using this for a few weeks now and I definitely do like it. It’s hard to tell what results you might see after only a few weeks (I feel like sometimes it might take months to see new hair growth etc.), but I do think I might have noticed some minor differences. I usually clean my hairbrush after every time brush, and I think I’ve been noticing a little less hair in my brush afterwards. If that means that I have less hair falling out, I’d consider it a win! My hair also feels nice and light and clean after use. I don’t think I’ve notice any extra volume, but to be honest, my hair is naturally so thin and limp I really didn’t expect it. I’m excited to continue using this product to see if I notice any further benefits. Anything that will help cut down on hair loss is a big yes yes yes for me! *I received this as a part of an educational promotion.*

So light but works insanely well

Phenomenal. I am so glad Olaplex came out with a version for fine hair because the original would weigh my hair down so much, no matter how little product I used. It was IMPOSSIBLE, to use and work with my hair. I’d have to wash my hair everyday but thankfully it didn’t cause a big issue. This scent that the olaplex shampoos have is one of my faves. So crisp and clean, the shampoo, a little still goes a long way but doesnt weigh done my hair; letting my curls really shine. I received this as a part of an educational promotions.

Pleasantly surprised on first try

I tried the No.4 bond maintenance strengthening and reparative hair shampoo for the first time, and honestly, I had low expectations about its cleansing power, but it left me speechless and not only did it make my hair feel clean without any greasy residue, but the scent is pleasant without being overwhelming, the best part is the undeniable result afterwards, shiny, silky hair. Truly a 1000/10! I received this product as part of an educational program

Clean and Healthy Hair

I’ve been using olaplex for years and this new fine bond maintenance shampoo is exactly what I’ve been looking for. It smells amazing and lathers easily into a rich and creamy foam. It leaves my hair feeling clean, removing all product build up, but without the brittle feeling. I like that it has no protein in it so there’s no risk of my hair turning brittle. It doesn’t strip my hair of its natural shine which I appreciate because it makes it look healthy and bouncy. It also gives me a good amount of volume at the root. Although I have high density hair, the individual strands are fine. I found that this shampoo does a great job at strengthening my hair over time. I’ve noticed less breakage when I use heat tools. I have also noticed less shedding in the shower. * Product was received as part of an educational promotion.

Fine hair to full-body hair!

I absolutely love the Olaplex No.4 FINE Bond Maintenance Volumizing and Strengthening Shampoo. I have long, but fine hair that is thin with ends that easily break. Most volumizing shampoos leave my hair feeling coarse; conditioners often leave my hair feeling weighed down. It's a struggle finding products that work with my fine hair to add volume and strengthen without feeling heavy. Well, HELLO Olaplex No. 4! The shampoo lathered beautifully without feeling harsh or stripping. My scalp felt thoroughly cleansed and refreshed. There was a noticeable difference just after one wash!!! After a week of using, my hair is obviously thicker, softer, and stronger. I paired it with No. 5 Fine Bond Maintenance Volumizing and Strengthening Conditioner. What a dynamic duo for fabulous, silky, full hair! I love that I get the strengthening and repair benefits Olaplex is known for, but in a formula designed specifically for finer hair. I received this product for free in exchange for my honest review.

Great strengthening shampoo, but a bit drying

I really like this shampoo because it makes my hair feel stronger and helps reduce breakage. It cleans well and gives some body without weighing my fine hair down. The only downside is that it can leave my hair feeling a bit dry, so I always need to follow up with conditioner or a mask. It might be slightly drying on me, but overall it delivers on strength and repair, so I’ll keep using it.

Concentrated and Clean!

I was so eager to try out a shampoo that was designed for people with fine hair like mine. I’ve been using the Olaplex Nº.4FINE Bond Maintenance shampoo for a week, and the results have been impressive. The shampoo feels light, yet effective, and it didn't dry out my hair. It lathered easily and rinsed clean. What stands out most is the added volume and lift at the roots, my fine hair appears fuller and has more body without feeling weighed down. I’ve also noticed my ends look smoother and less prone to breakage, making styling easier and my hair overall healthier. The fragrance is subtle and pleasant, never overwhelming, and I read that the formula is safe for color-treated hair, which is a priority for me. While the price point is on the higher side, the product is so concentrated that you only need to use a very small amount, which will make it last for a long time. *This review was collected as part of an educational promotion.

My honest opinion

This shampoo, once again I loved, its thick and concentrated texture. It feels that it moisturizes while cleaning the hair. This product is now part of my hair care routine. After removing the product, the hair feels incredible, soft, clean and hydrated. I received this as a part of an educational promotion."

This shampoo saved my hair!

I received this as a part of an educational promotion. I've been using this shampoo for the last couple of days, and I'm obsessed! My hair has been going through a lot of recent damage from bleaching, salty water from the summer vacation, and the Texas heat weather, which made my scalp itchy and gave me dandruff. I was considering cutting my hair to start fresh, but with this shampoo, I started feeling a huge difference from the first use. This shampoo didn't feel creamy or heavy, and it produced a good amount of foam with little effort. A small amount was enough for my hair, and it was easy to rinse out. The results were fantastic: my hair feels silky, my scalp doesn't feel dry, and there are no signs of dandruff. Very impressive product! My hair is 2a and fine, although I have a lot of hair, and I tend to air dry it and only apply other products when necessary, especially if my scalp feels dry or itchy, because I have to be very careful with the products I apply since plenty of products leave like a paste in my hair or make it greasy. But this one is lightweight, and actually, I feel it has helped to restore the movement of my hair as well. The bottle might look small, but it has almost the same amount of product as other brands, and I think the price is good considering the effectiveness and the fact that it's a specialized product. Also, it smells so good, and the smell remains on your hair by the end of the day (considering you showered in the morning). Recommended!

I have fine and thin hair (width of hair and density on head) and a little bit of dandruff as you can see in my dirty hair picture. This was too heavy for my hair. It cleaned my hair fairly thoroughly, but it was still too heavy for my hair even though it’s marketed for “fine hair.” And for this price point, it’s not worth it. I still gave it two stars since it did do a pretty good at removing my dandruff. I received this as a part of an educational promotion.
