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!

Este shampo es fantástico, repara, hace mi cabello mas fuerte, ya no se me rompe, y acompañado del # 5 han sido el DUO perfecto. This shampoo is amazing, it repairs and strengthens my hair, and it no longer breaks like before. Paired with No. 5, they have been the PERFECT duo.

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.

This is pretty much the best shampoo you can get. My stylist recommends this shampoo only, and it's awesome for my hair, which has to be chemically straightened due to its extreme frizzyness. I follow up with "It's a 10" leave-in conditioner ("miracle leave-in product"). Perfect combo.

I’ve been using Olaplex No. 4 Bond Maintenance Shampoo for a few months (based on the recommendation of my hair stylist), and the results have been great! It has completely eliminated frizz, leaving my hair soft, smooth, and with a beautiful shine. I don't usually need to use a conditioner. That said, it’s worth noting that this shampoo does contain a LOT of ingredients, which might be a concern for some. Hence the 4 stars. Although upon further research I read " OLAPLEX is colour-safe, vegan, PH balanced and completely free from cruelty, DEA, aldehydes, formaldehyde, silicone, parabens, sulphates, phosphates, gluten and nuts." While it has worked wonders for my hair, those who prefer all-natural products might want to look elsewhere. I rotate it with a more natural shampoo. It’s also definitely on the pricey side, but a little goes a long way—you only need a very small amount so the bottle lasts much longer than expected. For me, the results have been worth every penny, and I’ll keep buying it. If you’re looking for a product that can tackle frizz and leave your hair looking its best, this one is worth trying!
