I can’t say enough good things about this shampoo! I’ve been using it for a few weeks now, and the difference in my hair is incredible. It has transformed from dry, dull, and lifeless to shiny, smooth, and healthy-looking. The first thing I noticed was how gentle it is on my scalp—it lathers beautifully, and it has a pleasant, light fragrance that isn’t overpowering. After just the first wash, my hair felt softer and more hydrated, but over the course of the past few weeks, the changes have been dramatic. My hair feels significantly stronger and looks so much shinier without being greasy. I used to struggle with split ends and frizz, but now my hair feels nourished and less prone to breakage. It’s like I’ve had a mini hair revival. It’s so much easier to manage, and I can finally go a few extra days between washes without my hair looking flat or greasy. I’ve tried so many shampoos in the past that promised results but never delivered, but this one is the real deal. My hair feels healthier than it has in years, and I’m so happy I found it. Definitely a must-try if you’re looking to give your hair some love and restore its natural shine!

This Olaplex shampoo is one of the best hair products I have ever used. From the first washes, I noticed my hair felt softer, stronger, and much healthier. It really helps repair damage and leaves my hair smooth and shiny without weighing it down. The formula is gentle but very effective, and a little bit goes a long way, so the bottle lasts longer than expected. I also appreciate that it doesn’t have a strong or unpleasant scent, and it works well even on color-treated hair. Overall, this shampoo is worth every penny. It has truly improved the look and feel of my hair, and I highly recommend it to anyone who wants healthier, stronger, and more beautiful hair.

By far the best shampoo. My hair is so soft, and it does not tangle my hair like a lot of shampoos do.

This is, by far, the best shampoo. Even better- a tiny amount goes a very long way! I plan on purchasing more of their products soon.

I recently tried the Olaplex No. 4 Bond Maintenance Shampoo, and I must say it has completely transformed my hair care routine. As someone with color-treated and chemically processed hair, finding the right shampoo that not only cleanses but also nourishes and repairs is crucial. Olaplex No. 4 did not disappoint! Firstly, the scent is delightful and not overpowering. The shampoo lathers well, providing a luxurious and pampering experience in the shower. It leaves my hair feeling clean without that stripped or dry sensation that some shampoos can cause. The real magic, however, happens after the wash. I've noticed a significant improvement in the overall health of my hair since incorporating this product into my routine. My hair feels softer, stronger, and remarkably more manageable. The Olaplex formula truly lives up to its promise of repairing and maintaining hair bonds. Another standout feature is its color-preserving properties. Having invested time and money into my hair color, I'm thrilled to see that this shampoo helps extend the vibrancy of my color-treated hair, making salon visits less frequent. While the price may be a bit higher compared to other shampoos on the market, the results are worth every penny. A little goes a long way, so the bottle lasts a decent amount of time, making it a cost-effective investment in the long run. In conclusion, if you're looking for a shampoo that not only cleanses your hair but also repairs and maintains its health, Olaplex No. 4 Bond Maintenance Shampoo is a game-changer. It's become a staple in my hair care routine, and I highly recommend it to anyone looking to elevate their hair care experience.

This is the holy grail of hair products. I am in my late 40s and have thin, dry, color damaged hair. My hair has been frizzy and I could only wear a ponytail and even in that it would become a tangled rat mess. I have tried 100s of dollars in products from Keratin hair treatments, Aveda products, Nexus, Pantene, Its a 10, blowouts EVERYTHING under the sun and nothing was working. I was ready to shave my head and start over. Then I found this and read soooo many reviews and said shoot all I have to lose is more money. So for my fine, thin, color/highlighted damaged hair I got the 4/5 shampoo and conditioner, weightless nourishing mask,#3 Bond building hair and the #9 Bond Protector. My hair is now SOOOFFFTTT, not frizzy even when it is humid out (I live in the desert) so not many humid days until recently. This is all in just 3 days!!! Day one I used the Shampoo and Hair mask with already noticeable difference, Day 2 and 3 I used only the shampoo and conditioner. I started with the small bottles at $30 each and I am so far very pleased and plan on once I run out getting the larger bottles. I will tell you that you need a very very small amount of shampoo, it goes a LONG ways. The conditioner maybe a nickel size amount as it also goes a long ways. When I first used this and was done rinsing my hair, it did not feel soft and I was thinking okay I am going to not have fun brushing my wet hair and it was going to be a waste of money. Boy I was fooled. even though my hair did not feel soft and slick after conditioning, the wet brush I use as always just glided thru my hair with such ease. I was like oh okay and then once I dried it I was completely shocked at the difference the first wash alone had made. There were no tangles and the entire day my hair has been smooth, soft and manageable! I say take your chance and get this product, I hope you are as happy as I am with this. I plan on tossing every other hair product away now that this is the only thing that genuinely works for my hair in a way that I have never experienced with a hair product before.
