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.

I love what this shampoo does for my hair and how it makes my hair feel and behave. The scent is also very pleasant and barely noticeable. It's definitely up there in price, but after my hairdresser used it on my hair, I had to buy my own bottle. The good thing is that it really lathers up so you only need a tiny little bit of it each time. I think it will last longer than the other rather expensive shampoos I've been using, such as AG and others. My hair is fine, a bit past shoulder length, and I color it. I used to do highlights, but that became too damaging so I just went to a medium brown color and now only do the roots about every 6 weeks. Even this mild routine is hard on my fine and fragile hair, so I needed to try something different. I really do see a substantial difference in my hair with this shampoo, and it's not just hype. It makes my hair soft and not so flyaway, although since I also use the Olaplex 5 conditioner and #6 leave-in styler (which seems more like a leave-in conditioner), plus the #7 oil for the very ends, so all of these products together really make my hair behave and look better. Due to the price (ouch!), I'm careful to not waste any of the products, but from what I'm seeing after about 6 to 7 weeks of use so far, they will last quite a long time. Highly recommended, and definitely better for me than anything else I've used.

Was skeptical at first when I received. Seemed so tiny BUT a little goes a long way, amazing lather. I have medium length, wavy hair. My hair felt so soft, and so clean after shampooing. I think this bottle could last 5-6 months. I shampoo 2 times weakly. I'm sold!!°

I did a little experiment trying to figure out which shampoos are best for my dark, layered hair. I bought Redken Volume Injection Shampoo, Moroccanoil Hydration Shampoo, and Olaplex No. 4 Bond Maintenance Shampoo. Some shampoos leave my hair looking disappointingly flat, so I was determined to find one that could give me that salon-worthy volume. First up was Redken, but it was a total flop. My hair fell flat immediately after showering, and even after blow-drying with heat protection, it fell flat again later in the day. It was so lifeless that I didn't even bother using it again. Then I tried the Moroccanoil Hydration Shampoo. It left my hair feeling clean and nice, but it didn't really do anything special. It was just average, and not something I'd go out of my way to buy again unless it was heavily discounted. Finally, I tried Olaplex No. 4, and wow, what a revelation! This shampoo is worth every penny. My hair looks incredibly healthy and shiny, and it feels thicker. The best part is that it gives me the volume I usually only achieve after styling. With Olaplex, I can simply brush my hair after air drying, and it looks like I just had a professional blowout. I'm definitely repurchasing this one!

So good! It literally takes a pea size amount of shampoo to clean your whole head! Smells so nice! It is very pricey for a small 8oz bottle! But other than that it’s so good!!

When my hair stylist started using permanent hair color on my hair, it became brittle. Very distressing. She recommended Olaplex, 4, 5, and 6...use all of them. My hair was transformed back to the original character, smooth, healthy, no brittleness. What a relief.
