    • A Game-Changer for Curly, Color-Treated Hair!
Size: 3 Piece Set
As a 32-year-old with curly and heavily dyed hair, I've tried numerous products to maintain the health and vibrancy of my locks. Olaplex No. 4 Bond Maintenance Shampoo has been an absolute game-changer, earning high praise for its effectiveness and results. Restorative and Strengthening Formula: This shampoo works wonders in repairing the damage often associated with dyeing and heat styling. Its bond-building technology not only strengthens hair from within but also ensures long-lasting resilience. After just a few washes, I noticed my curls appeared more defined and less prone to breakage, transforming my hair’s overall texture and strength. Gentle Yet Effective Cleansing: Olaplex No. 4 provides a thorough cleanse without stripping my hair of its natural oils, which is crucial for maintaining hydration in curly hair. The gentle formulation ensures that my hair feels clean and refreshed, but never dry or brittle, preserving its natural bounce and shine. Color-Safe and Nourishing: One of the standout features for me is its color-safe formula. It helps preserve the vibrancy of my dyed hair, preventing the dreaded fade that often accompanies frequent washing. My hair not only looks healthier but also retains its salon-fresh color longer. Luxurious Feel and Lather: The shampoo has a rich lather and a pleasant fragrance, making each wash feel like a mini spa experience. It's concentrated so a little goes a long way, offering great value and ensuring the bottle lasts. Outstanding Results: Since incorporating Olaplex No. 4 into my haircare routine, I've received numerous compliments on how healthy and lush my hair looks. It has become an indispensable part of my regimen, providing the right balance of strength and nourishment. Conclusion: Olaplex No. 4 Bond Maintenance Shampoo is a must-have for anyone with curly, color-treated hair. Its ability to repair, strengthen, and protect makes it an invaluable ally in maintaining gorgeous, healthy curls. For its exceptional performance and transformative results, I highly recommend it. Five stars! 🌟🌟🌟🌟🌟 ... show more

    • I’ve used this before and know it’s top shelf.
Size: 8.5 Fl Oz (Pack of 1)
This is one of the very best shampoos that exist. I found it for 50% off yesterday so $15 instead of $30. I’m on a budget but I had to buy two! This is kind of one formula does it for everybody type of shampoo. It’s thick, it lathers up nicely, and it doesn’t make my hair oily which I tend to lean to the oily. It doesn’t leave a residue. This is very highly rated shampoo. All the products in this line are and they deserve to be. If you are undecided and reading 200 reviews, buy this! You won’t regret it. ... show more

    • Lovely Hair Is Not a Dream
Size: 8.5 Fl Oz (Pack of 1)
The bottle is heavy, so there is physical evidence that the formula is dense, as described. A little goes a long way. If I am trying new shampoo, it means I have an adversarial relationship with my hair. I was on a trip to northern Michigan, found a breakfast place in a 90% abandoned strip mall, and spotted a hair salon open, just over there. I came this close to walking in. I don't know what No. 4 Bond Maintenance means, but I haven't enjoyed my hair as much for years. I have been zoning my hair - leave-in conditioner on the ends, thickness spray in the middle and hair repair on the thinning top. Then I have to remember to not brush through. Don't touch! Hair spray to hide that balding cowlick. And now? I didn't remember I have a great haircut that has reached its optimum viewing. I have waves! I have shine! I have a new favorite shampoo. ... show more

    • Great shampoo #4
Size: 8.5 Fl Oz (Pack of 1)
This Shampoo #4 is part at a system. ( I previously used the #3 Hair Strengthener first) This shampoo is great, it cleans hair. I have very sensitive skin (Excezma) after using this shampoo there is no irritation or itching on scalp. Hair feels great, no perfume odors. Simple clean smell. The system is a little pricey #3, #4, and #5 were all bought together, but it’s worth the Money…. See my other reviews #3 and #5. Believe me it’s worth spending the money!! ... show more

    • Will last months
Size: 8.5 Fl Oz (Pack of 1)
A small amount, the sizes of a nickel is all you need. I only give 1 wash instead of 2 and my hair is very clean.

    • Amazing!
Size: 8.5 Fl Oz (Pack of 1)
I’ve never been a huge fan of any hair product I’ve tried. I recently noticed a lot of breakage of my hair, enough that I was constantly being asked by people if I got a haircut. I’ve only been using this for a month, and I notice a difference. I don’t notice my hair being any longer, but I’m sure I will with time. I’m not losing hair like I used to though! I actually used to wash my hair daily because it would look greasy if I skipped a day. Now, I wash 2-3 days a week and it looks fabulous every day. You don’t need nearly as much product as you think you’d need. Only docking a star because it’s expensive. However, I’m willing to watch for sales and keep using! ... show more

    • Amazing for bleached hair
Size: 8.5 Fl Oz (Pack of 1)
I love this product so far. It leaves my hair so soft and hydrated. Not only did I have dry damaged hair, but I also have bleached my hair quite a couple of times; overtime the color began to brass up. This shampoo helped revitalize the color into a nice ashy tone again.
