No.4 Bond Maintenance® - Shampoo

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!

great shampoo

Olaplex never disappointment me, this specific shampoo erase my frizz and let me hair smooth and soft with a beautiful gloss, i definitely recommend it .

Great product

I’ve been using the Olaplex Nº4 shampoo for fine hair, and honestly, it’s one of the best shampoos I’ve tried! From the very first wash, I could feel a difference in how clean and refreshed my hair felt — but without that dry or squeaky feeling. It lathers beautifully even with a small amount, and it doesn’t weigh my hair down at all, which is super important for fine strands. Over the past few days, my hair has felt stronger, softer, and looks visibly shinier. I’ve noticed less breakage when I brush, and it even helped reduce frizz, which is always a win. It also has a light, pleasant scent that makes washing my hair feel like a treat. I feel like it preps my hair perfectly for the conditioner. Definitely a new favorite in my routine!

Oleplex no4 bond maintenance

Product was received as part of an educational promotion. I used this for 7 days I love the smell left my hair smelling great. Left my hair feeling clean and didn’t strip the oils. But as far as strengthening or frizz it didn’t help I didn’t see a difference. I also had a lot of fallout out. Incentivized review.

Hair love!

Since I started using this Strengthening and Volumizing Shampoo from Olaplex, I’ve noticed BIG changes in my hair quality! It styles better, and also feels fuller. Definitely more manageable, with tons of shine! It looks gorgeous when I straighten it, very sleek and I appreciate the scent of the shampoo as well! It’s not an overpowering scent, more subtle I’d say. My hair feels stronger from root tip! My absolute favorite thing about this shampoo is that it doesn’t weigh my hair down! I have super fine hair, it gets tangled so easily! And I have a lot of hair too, to my waist to be exact! This shampoo literally is maintenance in a bottle! With hair to my waist, you can imagine how it is to maintain it! Finding a shampoo that not only nourishes my hair, adds shine, and strengthens it, And all without weighing it down is almost too good to be true! I love this shampoo and all it has to offer! All the fine hair girlies need to get you some #4 Bond maintenance, strengthening and volumizing shampoo from Olaplex like today! Don’t sleep on Olaplex & and all the hair care essentials! I’m quite literally sold, cuz girl!, my hair is hair’ing! I Highly recommend! I received this product complimentary, in exchange for my honest review.

Amazing

I’m so happy with the results of how this product left my hair . My hair was super damaged from heat and chemicals such as bleach but as soon as this product touched my hair it transformed it completely from being so dry to having bounce and volume and shine . I love that it’s not super strong in scent and the product is thick ! So a little goes a long way anyone has ever filled their hands with an abundance amount of shampoo to just have a clean feeling hair after washing? I am super guilty ! But not this time around I used a small amount and it did its magic . Also my scalp didn’t feel dry ! Which was the best part

Great shampoo

I have worked in the beauty industry for over 5 years and during this time I have tried many Shampoos. Usually when trying a shampoo I go for one that is hydrating for my curls but this time I went for one that is made for my fine hair. After using this shampoo for a week, my hair felt clean lopked shiny. It wasn't weighed down, which is a common issue that I have when trying hydrating shampoo and conditioner. I really enjoy the scent of this shampoo, it smells like citrus and I enjoy that the scent does not linger. It is a lightweight scent. I would recommend this shampoo to anyone who has fine hair and has issues with shampoo and conditioners weighing down their hair, but they are also looking for something that adds shine to their hair. *I received this product in exchange for my review.

I LOVED THIS PRODUCT

As someone with fine, afro-curly hair, it’s hard to find products that strengthen without making my hair feel heavy or greasy—but Olaplex No.4 (Bond Maintenance Shampoo) and No.5 (Bond Maintenance Conditioner) have truly impressed me. The shampoo cleanses gently, doesn’t strip my natural oils, and still leaves my scalp feeling fresh. The conditioner is rich, but not too thick—it melts into my curls and makes detangling a breeze. After a few washes, I noticed my curls looked more defined and less frizzy. What really stood out is how soft and strong my hair feels, especially in the fragile front areas. These products don’t weigh my hair down, which is essential for my fine texture. I also love that a little product goes a long way—definitely worth the price. Overall, this duo helps maintain moisture, reduce breakage, and keep my curls healthy, bouncy, and full of life.

Extra Love!

After moving from the Philippines to the U.S., my hair went through major changes—dryness, breakage, and rough texture. Olaplex No. 4 & No. 5 saved it. I use them whenever my hair needs extra love from too much sun or coloring. My strands feel stronger, smoother, and healthier every time. It’s my forever go-to.

❤️Love my healthy hair. ❤️

I’ve only been using the no.4 for fine hair for a week and I’m pleasantly surprised. I’ve been loving olaplex lately but I have trouble with my hair being heavy and greasy after washing. I can tell a difference when using this product. My hair feels soft , clean , and I have more volume when it dries. My split ends are looking better also. Love this shampoo and conditioner.
