No.4 Bond Maintenance® - Shampoo

Works great- no alternative!

I happily used olaplex for a year and then purchased a less expensive brand. Within weeks, the difference was apparent- Olaplex helps keep my hair strong and shiny, the other didn’t . I went back to Olaplex

I do like this one!

I do really like this shampoo! It’s not my regular go to but I throw it into the mix every now and then. Especially if I’m double cleansing, this is a good second cleanse option.

Underwhelming

I've been using the Nº.4 Bond Maintenance Shampoo from Olaplex for a while now, and unfortunately, it's not been the miracle worker I was hoping for. As someone with dry, damaged hair, I was excited to try a product that promised to repair and maintain bonds. While the shampoo does a great job of cleaning my hair, I haven't noticed any significant improvements in terms of repair or bond maintenance. My hair still feels dry and brittle, and I haven't seen a noticeable reduction in breakage. The formula is gentle and sulfate-free, which is a plus, but it's not particularly impressive in terms of moisturizing or nourishing my hair. I've had to use additional products to get the moisture and hydration my hair needs. Perhaps my expectations were too high, or this product just isn't suited to my hair type. Either way, I wouldn't recommend the Nº.4 Bond Maintenance Shampoo to those with very dry or damaged hair. There are other products on the market that might be more effective for specific hair concerns.

Really helped with my damaged and dry hair. I was having a lot of breakage and it did help with it for sure.

Great for my hair

If you’ve been dealing with damaged, dry, or chemically treated hair, Olaplex’s shampoo and conditioner duo might be the holy grail you’ve been searching for. I’ve been using the Olaplex No.4 Bond Maintenance Shampoo and No.5 Bond Maintenance Conditioner, and here’s my honest take:

Wonderful product!

I have been using the No. 4 for almost a year. My hair feels wonderful, very soft.

Not good for straight hair, perfect for curls

I had been really excited to try this product after years of hype but it was a real flop... It left my hair stringy, greasy, and unclean no matter how much I scrub or rinse it out. Not good for thick, straight, damaged hair. My partner who has thick curly hair likes it for the reasons I do not. Would not buy again or recommend.

Use the full product line for optimal results!

This product was given in exchange for an honest review. My hair was fuzzy, unrefined and lacked moisture. I was honestly at a place where I wanted to chop it off! This shampoo delivers intense hydration that my curls need, thanks to its rich formulation that softens the curls noticeably without making them limp or greasy. To see the best results, I used this shampoo along with No 3 Bond builder and No 5 conditioner . Together the products created the perfect solution to soften and moisturize my thirsty curls. Olaplex is a splurge-worthy shampoo that delivers hydration, softness, and curl definition for 3C curls. If you want to treat your hair like royalty, this is a solid investment but you may want to reserve it for pampering wash days.

Amazing shampoo

I absolutely love this shampoo. It lathers extremely well and it makes it easy to wash every inch of your hair with a small amount of product. It has a nice scent and the packaging is very simple and easy to recognize. I really appreciate simple packaging as it makes it easy to locate the brand in stores and read what the product is truly about. This shampoo is a little on the pricey end but in my opinion, it is totally worth it. It repairs any damage you have and strengthens hair even if it’s already strong. It livens up and volumizes your hair as well. I truly would recommend this shampoo to anyone. I started this hair journey with thinning hair and this has truly improved my mood and appearance.

LOVE IT

Olaplex No.4 Bond Maintenance Shampoo is my new best friend. I have been using this shampoo almost for a year and I love it! I have long long hair and this shampoo worth the investment. If you’re serious about reviving damaged or over-processed hair, Olaplex No.4 is a must-try. Pair it with other Olaplex products for the best results. Expect smoother, shinier, stronger hair that just feels healthier overall.

Love this shampoo

I genuinely swear by this shampoo. I have curly, frizzy hair that used to feel dry, unmanageable, and just all over the place—especially after washing. I’ve tried so many shampoos that claimed to help, but nothing worked the way Olaplex No. 4 does. It leaves my hair feeling clean but never stripped, and it’s made such a difference in how healthy, soft, and manageable my curls are. The frizz is way more under control, and my curls feel more defined without any extra effort. When my hair needs a little extra TLC, I love pairing it with No. 0 and No. 3 for a full repair treatment—it’s like a reset button for my hair. It’s definitely a bit of a splurge, but honestly, it’s been 100% worth it. If you’ve got curls that tend to frizz or feel damaged, this is a holy grail combo.

I wanted to try olaplex because I damaged my hair a lot with Flat iron, When I tried it for the first time, I noticed some hair falling out in the shower. At first, I thought it was normal, but as I kept using it more and more, I started seeing more and more hair falling out in the shower. I believe it’s because of this product or the entire line, because I’ve used other lines before and they don’t cause nearly as much hair loss.
